166.Salvia Lamiaceae.
Salvia is the largest genus of plants in the mint family, Lamiaceae, with nearly 1000 species of shrubs, herbaceous perennials, and annuals. Within the Lamiaceae, Salvia is member of the tribe Mentheae within the subfamily Nepetoideae. It is one of several genera commonly referred to as sage.
The genus is distributed throughout the Old World and the Americas, with three distinct regions of diversity: Central and South America (approx. 500 species); Central Asia and Mediterranean (250 species); Eastern Asia (90 species).
Description.
Salvia species include annual, biennial, or perennial herbs, along with woody subshrubs. The stems are typically angled like other members in Lamiaceae. The leaves are typically entire, but sometimes toothed or pinnately divided. The flowering stems bear small bracts, dissimilar to the basal leaves?in some species the bracts are ornamental and showy.
The flowers are produced in racemes, or panicles, and generally produce a showy display with flower colors ranging from blue to red, with white and yellow less common. The calyx is normally tubular or bell shaped, without bearded throats, and divided into two parts or lips, the upper lip entire or three-toothed, the lower two-cleft. The corollas are often claw shaped and are two-lipped. The upper lip is usually entire or three-toothed. The lower lip typically has two lobes. The stamens are reduced to two short structures with anthers two-celled, the upper cell fertile, and the lower imperfect. The flower styles are two-cleft. The fruits are smooth ovoid or oblong nutlets and in many species they have a mucilaginous coating.
Many salvias have trichomes (hairs) growing on the leaves, stems, and flowers, which help to reduce water loss in some species. Sometimes the hairs are glandular and secrete volatile oils that typically give a distinct aroma to the plant. When the hairs are rubbed or brushed, some of the oil-bearing cells are ruptured, releasing the oil. This often results in the plant being unattractive to grazing animals and some insects.
Staminal lever mechanism.

The defining characteristic of the genus Salvia is the unusual pollination mechanism. It is central to any investigation into the systematics, species radiation, or pollination biology of Salvia. It consists of two stamens (instead of the typical four found in other members of the tribe Mentheae) and the two thecae on each stamen are separated by an elongate connective. It is the elongation of the connective that enables the formation of the lever mechanism. Sprengel (1793) was the first to illustrate and describe the nototribic (dorsal) pollination mechanism in Salvia. When a pollinator probes a male stage flower for nectar, (pushing the posterior anther theca) the lever causes the stamens to move and the pollen to be deposited on the pollinator. When the pollinator withdraws from the flower, the lever returns the stamens to their original position. In older, female stage flowers, the stigma is bent down in a general location that corresponds to where the pollen was deposited on the pollinator's body. The lever of most Salvia species is not specialized for a single pollinator, but is generic and selected to be easily released by many bird and bee pollinators of varying shapes and sizes. The lever arm can be specialized to be different lengths so that the pollen is deposited on different parts of the pollinator?s body. For example, if a bee went to one flower and pollen was deposited on the far back of her body, but then it flew to another flower where the stigma was more forward (anterior), pollination could not take place. This can result in reproductive isolation from the parental population and new speciation can occur. It is believed that the lever mechanism is a key factor in the speciation, adaptive radiation, and diversity of this large genus.
Taxonomy.
History.
George Bentham was first to give a full monographic account of the genus in 1832-1836, and based his classifications on staminal morphology. Bentham's work on classifying the family Labiatae (Labiatarum Genera et Species (1836)) is still the only comprehensive and global organization of the family. While he was clear about the integrity of the overall family, he was less confident about his organization of Salvia, the largest genus in Labiatae (also called Lamiaceae). Based on his own philosophy of classification, he wrote that he "ought to have formed five or six genera" out of Salvia. In the end, he felt that the advantage in placing a relatively uniform grouping in one genus was "more than counterbalanced by the necessity of changing more than two hundred names." At that time there were only 291 known Salvia species.
Subdivision.
Bentham eventually organized Salvia into twelve sections (originally fourteen), based on differences in corolla, calyx, and stamens. These were placed into four subgenera that were generally divided into Old World and New World species:
Subgenus Salvia: Old World (Sections: Hymenosphace, Eusphace, Drymosphace)
Subgenus Sclarea: Old World (Sections: Horminum, Aethiposis, Plethiosphace)
Subgenus Calosphace: New World (Section: Calosphace)
Subgenus Leonia: Old and New World (Sections: Echinosphace, Pycnosphace, Heterosphace, Notiosphace, Hemisphace)
His system is still the most widely studied classification of Salvia, even though more than 500 new species have been discovered since his work. Other botanists have since offered modified versions of Bentham's classification system, while botanists in the last hundred years generally do not endorse Bentham's system.
It was long assumed that Salvia's unusual pollination and stamen structure had evolved only once, and that therefore Salvia was monophyletic, meaning that all members of the genus evolved from one ancestor. However, the immense diversity in staminal structure, vegetative habit, and floral morphology of the species within Salvia has opened the debate about its infrageneric classifications.
Phylogenetic analyses.
Through DNA sequencing, Salvia was shown to not be monophyletic but to consist of three separate clades (Salvia clades I-III) each with different sister groups. They also found that the staminal lever mechanism evolved at least two separate times, through convergent evolution. Walker and Sytsma (2007) clarified this parallel evolution in a later paper combining molecular and morphological data to prove three independent lineages of the Salvia lever mechanism, each corresponding to a clade within the genus. It is surprising to see how similar the staminal lever mechanism structures are between the three lineages, so Salvia proves to be an interesting but excellent example of convergent evolution.
Walker and Sytsma (2007) also addressed the question of whether Salvia is truly polyphyletic or just paraphyletic within the tribe Mentheae. To make Salvia monophyletic would require the inclusion of 13 species from Rosmarinus, Perovskia, Dorystaechas, Meriandra, and Zhumeria genera. The information attained by Walker and Sytsma (2007) supporting the three independent origins of the staminal lever indicate that Salvia is not the case where 13 species (currently not members of the genus) are actually members of Salvia but underwent character reversals?in other words, Salvia is paraphyletic. Instead, Salvia is defined by its convergent character of distinct staminal evolution that proves its polyphyly.
The description of individual species within Salvia has undergone constant revision. Many species are similar to each other, and many species have varieties that have been given different specific names. There have been as many as 2,000 named species and subspecies. Over time, the number has been reduced to less than a thousand. A modern and comprehensive study of Salvia species was done by Gabriel Alziar, in his Catalogue Synonymique des Salvia du Monde (1989) (World Catalog of Salvia Synonyms). He found that the number of distinct species and subspecies could be reduced to less than 700.
Selected species and their uses.
Main article: List of Salvia species.
Many species are used as herbs, as ornamental plants (usually for flower interest), and sometimes for their ornamental and aromatic foliage. The Plant List has 986 accepted species names. A selection of some well known species is below.
Salvia apiana is the white sage sacred to a number of U.S. Native American Peoples, and used by some tribes in their ceremonies.
Salvia cacaliifolia is the blue wine sage or Guatemalan sage blooming with many pure gentian-blue flowers.
Salvia divinorum, or diviner's sage, is sometimes cultivated for psychedelic drug effects; the legality of its use is under review in some US states.
Salvia elegans, the pineapple sage, is widely grown as an ornamental shrub or sub-shrub, with pineapple scented leaves.
Salvia fruticosa, called Greek sage or just sage is commonly grown and harvested as an alternative to common sage.
Salvia hispanica, commonly known as chia, produces edible seeds which are high in protein and in the omega-3 fatty acid, ?-linolenic acid (ALA).
Salvia leucantha, Mexican bush sage or woolly sage, is grown as an ornamental in warm climates for its drooping flower heads, with white flowers emerging from furry blue or purple bracts.
Salvia microphylla from Mexico, sometimes called baby sage, is a small shrub grown extensively for its red (sometimes pink or white) flowers, and its fruit scented leaves.
Salvia miltiorrhiza, Chinese, Red sage, Danshen medicinal herb.
Salvia nemorosa, Woodland sage, ornamental
Salvia officinalis, or common sage is used widely in cooking, as an ornamental and landscape plant, and in herbal medicine.
Salvia sclarea, clary or clary sage, is grown as an ornamental and to some extent for perfume oils.
Salvia splendens or scarlet sage is a popular ornamental bedding or pot plant.
Salvia guaranitica or 'hummingbird sage' is grown as an ornamental flower.
Salvia species are used as food plants by the larvae of some Lepidoptera (butterfly and moth) species including the bucculatricid leaf-miner Bucculatrix taeniola which feeds exclusively on the genus and the Coleophora case-bearers C. aegyptiacae, C. salviella (both feed exclusively on S. aegyptiaca), C. ornatipennella and C. virgatella (both recorded on S. pratensis).
Etymology.
The name Salvia "salviya" derives from the Latin salvere ("to feel well and healthy, health, heal"), the verb related to salus (health, well-being, prosperity or salvation); referring to the herb's healing properties. Pliny the Elder was the first author known to describe a plant called "Salvia" by the Romans, likely describing the type species for the genus Salvia, Salvia officinalis.
The common modern English name sage derives from Middle English sawge, which was borrowed from Old French sauge, and like the botanical name, stems from Latin salvere. When used without modifiers, the name 'sage' generally refers to Salvia officinalis ("common sage" or "culinary sage"); however, it is used with modifiers to refer to any member of the genus. The ornamental species are commonly referred to by their genus name Salvia.

167.All the King's Men by Robert Penn Warren.
All the King's Men is a novel by Robert Penn Warren first published in 1946. Its title is drawn from the nursery rhyme Humpty Dumpty. In 1947 Warren won the Pulitzer Prize for All the King's Men. It was adapted for film in 1949 and 2006; the 1949 version won the Academy Award for Best Picture. It is rated the 36th greatest novel of the 20th century by Modern Library, and it was chosen as one of TIME magazine's 100 best novels since 1923.
Plot.
All the King's Men portrays the dramatic political rise and governorship of Willie Stark, a cynical populist in the American South during the 1930s. The novel is narrated by Jack Burden, a political reporter who comes to work as Governor Stark's right-hand man. The trajectory of Stark's career is interwoven with Jack Burden's life story and philosophical reflections: "the story of Willie Stark and the story of Jack Burden are, in one sense, one story."
The novel evolved from a verse play that Warren began writing in 1936 entitled Proud Flesh. One of the characters in Proud Flesh was named Willie Talos, in reference to the brutal character Talus in Edmund Spenser's late 16th century work The Faerie Queene.
The version of All the King's Men edited by Noel Polk (ISBN 0-15-100610-5) uses the name "Willie Talos" for the Boss as originally written in Warren's manuscript, and is known as the "restored version" for using this name as well as printing several passages removed from the original edit.
Warren claimed that All the King's Men was "never intended to be a book about politics."
Themes and imagery.
One central motif of the novel is that all actions have consequences, and that it is impossible for an individual to stand aloof and be a mere observer of life, as Jack tries to do (first as a graduate student doing historical research and later as a wisecracking newspaperman). In the atmosphere of the 1930s, whole populations seemed to abandon responsibility by living vicariously through messianic political figures like Willie Stark. Thus, Stark fulfills the wishes of many of the characters, or seems to do so. For instance, his faithful bodyguard Sugar-Boy, who stutters, loves Stark because "the b-boss could t-talk so good"; Jack Burden cannot bring himself to sleep with Anne Stanton, whom he loves, but Stark does so; and so on. (It is in this sense that the characters are "all the king's men"; other than borrowing this familiar phrase, the title has nothing to do with the story of Humpty Dumpty. The title is possibly derived from the motto of Huey P. Long, whose life was similar to that of Willie Stark, "Every Man a King".) But this vicarious achievement will eventually fail; ultimately Jack realizes that one must "go out of history into history and the awful responsibility of Time."
The novel explores conceptions of Calvinist theology, such as original sin ("Man is conceived in sin and born in corruption, and he passeth from the stink of the dydie to the stench of the shroud," says Willie when told that no adverse information about an opponent would be likely to be found. "There's always something"); and total depravity ("You got to make good out of bad," says Willie when his ruthless methods are criticized. "That's all there is to make it with.") Jack discovers that no man is invulnerable to sin under the right circumstances, and thus his search for dirt on the judge begins with questions as to what circumstances would cause one to do wrong. Jack, Willie, and Adam all abandon idealism when they realize that nobody is pure and unblemished.
Another motif in the novel is the "Great Twitch." When Jack Burden unexpectedly discovers that the love of his life, Anne Stanton, has been sleeping with Governor Willie Stark, he impulsively jumps in his car and drives to California to obtain some distance from the situation. Jack's description of his trip contains overt and indirect references to the notion of Manifest Destiny, which becomes somewhat ironic when he comes back from it believing in the "Great Twitch."
The "Great Twitch" is a particular brand of nihilism that Jack embraces during this journey westward: "all the words we speak meant nothing and there was only the pulse in the blood and the twitch of the nerve, like a dead frog's leg in the experiment when the electric current goes through." On his way back from California, Jack gives a ride to an old man who has an involuntary facial twitch. This image becomes for him the encapsulating metaphor for the idea that "all life is but the dark heave of blood and the twitch of the nerve." In other words, life is without meaning; everything is motivated by some inborn reflex action and nobody is responsible for their choices or even their own destiny. (The concept is brought to life for Jack when he witnesses a lobotomy performed by Adam Stanton.) The emotional distance permitted by this revelation releases Jack from his own frustration stemming from the relationship between Anne Stanton and his boss, and allows him to return to circumstances which were previously unbearable.
Subsequent events (including the tragic deaths of Governor Stark, Jack's lifelong friend Adam Stanton, and Judge Irwin, Jack's father) convince Jack that the revelation of the "Great Twitch" is an insufficient paradigm to explain what he has seen of history. "[H]e saw that though doomed, [his friends] had nothing to do with any doom under the godhead of the Great Twitch. They were doomed, but they lived in the agony of will." Ultimately, he grows to accept some responsibility for his part in the destruction of his friends' lives.
The book also touches on Oedipal themes, as Jack discovers his father's true identity after having caused his death.
The theme of one's father's identity and its effects on one's own sense of identity is explored twice in the novel, first through Adam and Anne's painful discovery that their father (the late Governor Stanton) once assisted in the cover-up of a bribery scandal. Then Jack discovers that his biological father is Judge Irwin, not, as he previously believed, "the Scholarly Attorney." In each case, the discovery catalyzes an upheaval in the character's moral outlook.
Time is another of the novel's thematic fascinations. The idea that every moment in the past contains the seeds of the future is constantly explored through the novel's non-chronological narrative, which reveals character continuities and thematic connections across different time periods.
Characters.
Willie Stark.
The central character of Willie Stark (often simply referred to as "the Boss") undergoes a radical transformation from an idealistic lawyer and weak gubernatorial candidate into a charismatic and extraordinarily powerful governor. In achieving this office Stark comes to embrace various forms of corruption and builds an enormous political machine based on patronage and intimidation. His approach to politics earns him many enemies in the state legislature, but does not detract from his popular appeal among many of his constituents, who respond with enthusiasm to his fiery populist manner.
Stark's character is often thought to be inspired by the life of Huey P. Long, former governor of Louisiana and that state's U.S. senator in the mid-1930s. Huey Long was at the zenith of his career when he was assassinated in 1935; just a year earlier, Robert Penn Warren had begun teaching at Louisiana State University. Stark, like Long, is shot to death in the state capitol building by a physician. The title of the book possibly came from Long's motto, "Every Man a King."
In his introduction to the Modern Library edition, Warren denied that the book should be read as either praise for Huey Long or praise for his assassination. However, Warren did not deny that Long served as an influence or inspiration for Stark:
One of the unfortunate characteristics of our time is that the reception of a novel may depend on its journalistic relevance. It is a little graceless of me to call this characteristic unfortunate, and to quarrel with it, for certainly the journalistic relevance of All the King's Men had a good deal to do with what interest it evoked. My politician hero, whose name, in the end, was Willie Stark, was quickly equated with the late [US] Senator Huey P. Long....
This equation led, in different quarters, to quite contradictory interpretations of the novel. On one hand, there were those who took the thing to be a not-so-covert biography of, and apologia for, Senator Long, and the author to be not less than a base minion of the great man. There is really nothing to reply to this innocent boneheadedness or gospel-bit hysteria. As Louis Armstrong is reported to have said, there's some folks that, if they don't know, you can't tell 'em... But on the other hand, there were those who took the thing to be a rousing declaration of democratic principles and a tract for the assassination of dictators. This view, though somewhat more congenial to my personal political views, was almost as wide of the mark. For better or worse, Willie Stark was not Huey Long. Willie [Stark] was only himself....
[T]he difference between the person Huey P. Long and the fiction Willie Stark, may be indicated by the fact that in the verse play [Proud Flesh] the name of the politician was Talos ? the name of the brutal, blank-eyed 'iron groom' of Spenser's Fairie Queene, the pitiless servant of the knight of justice. My conception grew wider, but that element always remained, and Willie Stark remained, in one way, Willie Talos. In other words, Talos is the kind of doom that democracy may invite upon itself. The book, however, was never intended to be a book about politics. Politics merely provided the framework story in which the deeper concerns, whatever their final significance, might work themselves out.
Jack Burden.
Jack Burden is the novel's narrator, a former student of history, newspaper columnist, and personal aide to Governor Willie Stark.
His narrative is propelled in part by a fascination with the mystery of Stark's larger-than-life character, and equally by his struggle to discover some underlying principle to make sense of all that has happened.
In narrating the story, Jack commingles his own personal story with the political story of Governor Stark. His telling of these two stories side by side creates a striking contrast between the personal and the impersonal. While his wry, detached, often humorous tone suggests an attempt to stand apart from the other characters' passions and intrigues, the highly personal content of his narrative suggests an awareness that he cannot truthfully remove himself and his own history from the story of Willie Stark, because his own story has paralleled and helped shape the tragic outcome of Stark's story.
Jack's overall character development might be roughly described as a journey away from an amoral perspective on human history as a chain of uncontrollable events, toward a belief in the fundamental interconnectedness of all of history. In other words, he might be said to trace a path from refusal to acceptance of personal responsibility. On the other hand, one defining trait that remains a constant throughout Jack's development is a passion for discovering the truth of history.
"And all times are one time, and all those dead in the past never lived before our definition gives them life, and out of the shadow their eyes implore us. That is what all of us historical researchers believe. And we love truth." [p. 342]
Anne Stanton.
Anne is Jack Burden's childhood sweetheart and the daughter of Willie Stark's political predecessor, Governor Stanton. Many of the novel's passages recounting Jack's life story revolve around memories of his relationship with Anne. Like many of Jack's friends, Anne disapproves of Willie Stark. However, in the wake of a devastating revelation regarding one of her father's moral lapses, she has an affair with Stark.
Adam Stanton.
Adam is a highly successful doctor, Anne Stanton's brother, and Jack Burden's childhood friend. Jack comes to view Adam Stanton as the polar opposite of Governor Stark, calling Adam "the man of idea" and Stark "the man of fact". Elsewhere, he describes Adam's central motivation as a deep need to "do good". Governor Stark invites Adam to be director of his pet project, a new hospital and medical center. The position initially strikes Adam as repugnant because of his revulsion to Stark's politics, but Jack and Anne ultimately persuade him to accept the invitation, essentially by removing his moral high ground. Adam's sense of violation as a result of his entanglement with Governor Stark proves violently tragic when he is informed by Lieutenant Governor Tiny Duffy that Stark has been sleeping with his sister. His pride demolished, Adam finds the Governor at the Capitol building and shoots him. To the extent that Willie Stark's story may have been loosely based on real-life events, the inspiration behind Adam Stanton's character would have been Dr. Carl Weiss.
Judge Irwin.
Judge Irwin is an elderly gentleman whom Jack has known since childhood, a man who is essentially a father-figure to him. Willie Stark assigns Jack the task of digging through Irwin's past to find something from the past with which Irwin can be blackmailed. Jack investigates thoroughly and finds what he is looking for: an incident many years ago when Judge Irwin took a bribe to dismiss a lawsuit against a fuel company, resulting in the personal destruction of a man named Mortimer Littlepaugh. Jack presents the incriminating evidence to Irwin, and before he has a chance to use it against him, Irwin commits suicide. Only at this point does Jack learn from his mother that Irwin was his father.
Cass Mastern.
One of Jack Burden's first major historical research projects revolves around the life of a 19th-century collateral ancestor, Cass Mastern, a man of high moral standards and a student at Transylvania College in Kentucky (Robert Penn Warren's native state). Cass's story, as revealed through his journals and letters, is essentially about a single betrayal of a friend that seems to ripple endlessly outward with negative consequences for many people. In studying this fragment of Civil War?era history, Jack begins to suspect (but cannot yet bring himself to accept) the idea that every event has unforeseen and unknowable implications, and that all actions and all persons are connected to other actions and other persons. Jack suggests that one reason he is unable to complete his dissertation on Cass's life is that perhaps "he was afraid to understand for what might be understood there was a reproach to him."
Cass Mastern and his moral challenges parallel those of Jack, something Jack does not understand when he is doing his doctoral dissertation on Mastern and one of the reasons that Burden abandons it. It is only at the end of the novel that Jack realizes this.

168.Crystal or Crystalline Solid.
A crystal or crystalline solid is a solid material whose constituents, such as atoms, molecules or ions, are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations.
The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word crystal is derived from the Ancient Greek word ?????????? (krustallos), meaning both ?ice? and ?rock crystal?, from ????? (kruos), "icy cold, frost".
Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Examples of polycrystals include most metals, rocks, ceramics, and ice. A third category of solids is amorphous solids, where the atoms have no periodic structure whatsoever. Examples of amorphous solids include glass, wax, and many plastics.
Crystal structure (microscopic)
Halite (table salt, NaCl): Microscopic and macroscopic.
Microscopic structure of a halite crystal. (Purple is sodium ion, green is chlorine ion.) There is cubic symmetry in the atoms' arrangement.
Macroscopic (~16cm) halite crystal. The right-angles between crystal faces are due to the cubic symmetry of the atoms' arrangement.
Main article: Crystal structure.
The scientific definition of a "crystal" is based on the microscopic arrangement of atoms inside it, called the crystal structure. A crystal is a solid where the atoms form a periodic arrangement. (Quasicrystals are an exception, see below.)
Not all solids are crystals. For example, when liquid water starts freezing, the phase change begins with small ice crystals that grow until they fuse, forming a polycrystalline structure. In the final block of ice, each of the small crystals (called "crystallites" or "grains") is a true crystal with a periodic arrangement of atoms, but the whole polycrystal does not have a periodic arrangement of atoms, because the periodic pattern is broken at the grain boundaries. Most macroscopic inorganic solids are polycrystalline, including almost all metals, ceramics, ice, rocks, etc. Solids that are neither crystalline nor polycrystalline, such as glass, are called amorphous solids, also called glassy, vitreous, or noncrystalline. These have no periodic order, even microscopically. There are distinct differences between crystalline solids and amorphous solids: most notably, the process of forming a glass does not release the latent heat of fusion, but forming a crystal does.
A crystal structure (an arrangement of atoms in a crystal) is characterized by its unit cell, a small imaginary box containing one or more atoms in a specific spatial arrangement. The unit cells are stacked in three-dimensional space to form the crystal.
The symmetry of a crystal is constrained by the requirement that the unit cells stack perfectly with no gaps. There are 219 possible crystal symmetries, called crystallographic space groups. These are grouped into 7 crystal systems, such as cubic crystal system (where the crystals may form cubes or rectangular boxes, such as halite shown at right) or hexagonal crystal system (where the crystals may form hexagons, such as ordinary water ice).
Crystal faces and shapes.
As a halite crystal is growing, new atoms can very easily attach to the parts of the surface with rough atomic-scale structure and many dangling bonds. Therefore these parts of the crystal grow out very quickly (yellow arrows). Eventually, the whole surface consists of smooth, stable faces, where new atoms cannot as easily attach themselves.
Crystals are commonly recognized by their shape, consisting of flat faces with sharp angles. These shape characteristics are not necessary for a crystal?a crystal is scientifically defined by its microscopic atomic arrangement, not its macroscopic shape?but the characteristic macroscopic shape is often present and easy to see.
Euhedral crystals are those with obvious, well-formed flat faces. Anhedral crystals do not, usually because the crystal is one grain in a polycrystalline solid.
The flat faces (also called facets) of a euhedral crystal are oriented in a specific way relative to the underlying atomic arrangement of the crystal: They are planes of relatively low Miller index. This occurs because some surface orientations are more stable than others (lower surface energy). As a crystal grows, new atoms attach easily to the rougher and less stable parts of the surface, but less easily to the flat, stable surfaces. Therefore, the flat surfaces tend to grow larger and smoother, until the whole crystal surface consists of these plane surfaces. (See diagram on right.)
One of the oldest techniques in the science of crystallography consists of measuring the three-dimensional orientations of the faces of a crystal, and using them to infer the underlying crystal symmetry.
A crystal's habit is its visible external shape. This is determined by the crystal structure (which restricts the possible facet orientations), the specific crystal chemistry and bonding (which may favor some facet types over others), and the conditions under which the crystal formed.
Occurrence in nature.
Ice crystals.

Rocks.
By volume and weight, the largest concentrations of crystals in the earth are part of the Earth's solid bedrock.
Some crystals have formed by magmatic and metamorphic processes, giving origin to large masses of crystalline rock. The vast majority of igneous rocks are formed from molten magma and the degree of crystallization depends primarily on the conditions under which they solidified. Such rocks as granite, which have cooled very slowly and under great pressures, have completely crystallized; but many kinds of lava were poured out at the surface and cooled very rapidly, and in this latter group a small amount of amorphous or glassy matter is common. Other crystalline rocks, the metamorphic rocks such as marbles, mica-schists and quartzites, are recrystallized. This means that they were at first fragmental rocks like limestone, shale and sandstone and have never been in a molten condition nor entirely in solution, but the high temperature and pressure conditions of metamorphism have acted on them by erasing their original structures and inducing recrystallization in the solid state.
Other rock crystals have formed out of precipitation from fluids, commonly water, to form druses or quartz veins. The evaporites such as halite, gypsum and some limestones have been deposited from aqueous solution, mostly owing to evaporation in arid climates.
Ice.
Water-based ice in the form of snow, sea ice and glaciers is a very common manifestation of crystalline or polycrystalline matter on Earth. A single snowflake is typically a single crystal, while an ice cube is a polycrystal.
Organigenic crystals.
Many living organisms are able to produce crystals, for example calcite and aragonite in the case of most molluscs or hydroxylapatite in the case of vertebrates.
Polymorphism and allotropy.
Main articles: Polymorphism (materials science) and Allotropy.
The same group of atoms can often solidify in many different ways. Polymorphism is the ability of a solid to exist in more than one crystal form. For example, water ice is ordinarily found in the hexagonal form Ice Ih, but can also exist as the cubic Ice Ic, the rhombohedral ice II, and many other forms. The different polymorphs are usually called different phases.
In addition, the same atoms may be able to form noncrystalline phases. For example, water can also form amorphous ice, while SiO2 can form both fused silica (an amorphous glass) and quartz (a crystal). Likewise, if a substance can form crystals, it can also form polycrystals.
For pure chemical elements, polymorphism is known as allotropy. For example, diamond and graphite are two crystalline forms of carbon, while amorphous carbon is a noncrystalline form. Polymorphs, despite having the same atoms, may have wildly different properties. For example, diamond is among the hardest substances known, while graphite is so soft that it is used as a lubricant.
Polyamorphism is a similar phenomenon where the same atoms can exist in more than one amorphous solid form.

Main articles: Crystallization and Crystal growth.
Crystallization is the process of forming a crystalline structure from a fluid or from materials dissolved in a fluid. (More rarely, crystals may be deposited directly from gas; see thin-film deposition and epitaxy.)
Crystallization is a complex and extensively-studied field, because depending on the conditions, a single fluid can solidify into many different possible forms. It can form a single crystal, perhaps with various possible phases, stoichiometries, impurities, defects, and habits. Or, it can form a polycrystal, with various possibilities for the size, arrangement, orientation, and phase of its grains. The final form of the solid is determined by the conditions under which the fluid is being solidified, such as the chemistry of the fluid, the ambient pressure, the temperature, and the speed with which all these parameters are changing.
Specific industrial techniques to produce large single crystals (called boules) include the Czochralski process and the Bridgman technique. Other less exotic methods of crystallization may be used, depending on the physical properties of the substance, including hydrothermal synthesis, sublimation, or simply solvent-based crystallization.
Large single crystals can be created by geological processes. For example, selenite crystals in excess of 10 meters are found in the Cave of the Crystals in Naica, Mexico. For more details on geological crystal formation, see above.
Crystals can also be formed by biological processes, see above. Conversely, some organisms have special techniques to prevent crystallization from occurring, such as antifreeze proteins.
Defects, impurities, and twinning.
Main articles: Crystallographic defect, Impurity, Crystal twinning and Mosaicity.
Two types of crystallographic defects. Top right: edge dislocation. Bottom right: screw dislocation.
An ideal crystal has every atom in a perfect, exactly repeating pattern. However, in reality, most crystalline materials have a variety of crystallographic defects, places where the crystal's pattern is interrupted. The types and structures of these defects may have a profound effect on the properties of the materials.
A few examples of crystallographic defects include vacancy defects (an empty space where an atom should fit), interstitial defects (an extra atom squeezed in where it does not fit), and dislocations (see figure at right). Dislocations are especially important in materials science, because they help determine the mechanical strength of materials.
Another common type of crystallographic defect is an impurity, meaning that the "wrong" type of atom is present in a crystal. For example, a perfect crystal of diamond would only contain carbon atoms, but a real crystal might perhaps contain a few boron atoms as well. These boron impurities change the diamond's color to slightly blue. Likewise, the only difference between ruby and sapphire is the type of impurities present in a corundum crystal.
Twinned pyrite crystal group.
In semiconductors, a special type of impurity, called a dopant, drastically changes the crystal's electrical properties. Semiconductor devices, such as transistors, are made possible largely by putting different semiconductor dopants into different places, in specific patterns.
Twinning is a phenomenon somewhere between a crystallographic defect and a grain boundary. Like a grain boundary, a twin boundary has different crystal orientations on its two sides. But unlike a grain boundary, the orientations are not random, but related in a specific, mirror-image way.
Mosaicity is a spread of crystal plane orientations. A mosaic crystal is supposed to consist of smaller crystalline units that are somewhat misaligned with respect to each other.
Chemical bonds.
Crystalline structures occur in all classes of materials, with all types of chemical bonds. Almost all metal exists in a polycrystalline state; amorphous or single-crystal metals must be produced synthetically, often with great difficulty. Ionically bonded crystals can form upon solidification of salts, either from a molten fluid or upon crystallization from a solution. Covalently bonded crystals are also very common, notable examples being diamond, silica, and graphite. Polymer materials generally will form crystalline regions, but the lengths of the molecules usually prevent complete crystallization. Weak van der Waals forces can also play a role in a crystal structure; for example, this type of bonding loosely holds together the hexagonal-patterned sheets in graphite.

Quasicrystals.
The material Ho-Mg-Zn forms quasicrystals, which can take on the macroscopic shape of a dodecahedron. (Only a quasicrystal, not a normal crystal, can take this shape.) The edges are 2mm long.
Main article: Quasicrystal.
A quasicrystal consists of arrays of atoms that are ordered but not strictly periodic. They have many attributes in common with ordinary crystals, such as displaying a discrete pattern in x-ray diffraction, and the ability to form shapes with smooth, flat faces.
Quasicrystals are most famous for their ability to show five-fold symmetry, which is impossible for an ordinary periodic crystal (see crystallographic restriction theorem).
The International Union of Crystallography has redefined the term "crystal" to include both ordinary periodic crystals and quasicrystals ("any solid having an essentially discrete diffraction diagram").
Quasicrystals, first discovered in 1982, are quite rare in practice. Only about 100 solids are known to form quasicrystals, compared to about 400,000 periodic crystals measured to date. The 2011 Nobel Prize in Chemistry was awarded to Dan Shechtman for the discovery of quasicrystals.
Special properties from anisotropy.
See also: Crystal optics.
Crystals can have certain special electrical, optical, and mechanical properties that glass and polycrystals normally cannot. These properties are related to the anisotropy of the crystal, i.e. the lack of rotational symmetry in its atomic arrangement. One such property is the piezoelectric effect, where a voltage across the crystal can shrink or stretch it. Another is birefringence, where a double image appears when looking through a crystal. Moreover, various properties of a crystal, including electrical conductivity, electrical permittivity, and Young's modulus, may be different in different directions in a crystal. For example, graphite crystals consist of a stack of sheets, and although each individual sheet is mechanically very strong, the sheets are rather loosely bound to each other. Therefore, the mechanical strength of the material is quite different depending on the direction of stress.
Not all crystals have all of these properties. Conversely, these properties are not quite exclusive to crystals. They can appear in glasses or polycrystals that have been made anisotropic by working or stress?for example, stress-induced birefringence.

Crystallography is the science of measuring the crystal structure (in other words, the atomic arrangement) of a crystal. One widely used crystallography technique is X-ray diffraction. Large numbers of known crystal structures are stored in crystallographic databases.

166.Salvia Lamiaceae.
Salvia is the largest genus of plants in the mint family, Lamiaceae, with nearly 1000 species of shrubs, herbaceous perennials, and annuals. Within the Lamiaceae, Salvia is member of the tribe Mentheae within the subfamily Nepetoideae. It is one of several genera commonly referred to as sage.
The genus is distributed throughout the Old World and the Americas, with three distinct regions of diversity: Central and South America (approx. 500 species); Central Asia and Mediterranean (250 species); Eastern Asia (90 species).
Description.
Salvia species include annual, biennial, or perennial herbs, along with woody subshrubs. The stems are typically angled like other members in Lamiaceae. The leaves are typically entire, but sometimes toothed or pinnately divided. The flowering stems bear small bracts, dissimilar to the basal leaves?in some species the bracts are ornamental and showy.
The flowers are produced in racemes, or panicles, and generally produce a showy display with flower colors ranging from blue to red, with white and yellow less common. The calyx is normally tubular or bell shaped, without bearded throats, and divided into two parts or lips, the upper lip entire or three-toothed, the lower two-cleft. The corollas are often claw shaped and are two-lipped. The upper lip is usually entire or three-toothed. The lower lip typically has two lobes. The stamens are reduced to two short structures with anthers two-celled, the upper cell fertile, and the lower imperfect. The flower styles are two-cleft. The fruits are smooth ovoid or oblong nutlets and in many species they have a mucilaginous coating.
Many salvias have trichomes (hairs) growing on the leaves, stems, and flowers, which help to reduce water loss in some species. Sometimes the hairs are glandular and secrete volatile oils that typically give a distinct aroma to the plant. When the hairs are rubbed or brushed, some of the oil-bearing cells are ruptured, releasing the oil. This often results in the plant being unattractive to grazing animals and some insects.
Staminal lever mechanism.

The defining characteristic of the genus Salvia is the unusual pollination mechanism. It is central to any investigation into the systematics, species radiation, or pollination biology of Salvia. It consists of two stamens (instead of the typical four found in other members of the tribe Mentheae) and the two thecae on each stamen are separated by an elongate connective. It is the elongation of the connective that enables the formation of the lever mechanism. Sprengel (1793) was the first to illustrate and describe the nototribic (dorsal) pollination mechanism in Salvia. When a pollinator probes a male stage flower for nectar, (pushing the posterior anther theca) the lever causes the stamens to move and the pollen to be deposited on the pollinator. When the pollinator withdraws from the flower, the lever returns the stamens to their original position. In older, female stage flowers, the stigma is bent down in a general location that corresponds to where the pollen was deposited on the pollinator's body. The lever of most Salvia species is not specialized for a single pollinator, but is generic and selected to be easily released by many bird and bee pollinators of varying shapes and sizes. The lever arm can be specialized to be different lengths so that the pollen is deposited on different parts of the pollinator?s body. For example, if a bee went to one flower and pollen was deposited on the far back of her body, but then it flew to another flower where the stigma was more forward (anterior), pollination could not take place. This can result in reproductive isolation from the parental population and new speciation can occur. It is believed that the lever mechanism is a key factor in the speciation, adaptive radiation, and diversity of this large genus.
Taxonomy.
History.
George Bentham was first to give a full monographic account of the genus in 1832-1836, and based his classifications on staminal morphology. Bentham's work on classifying the family Labiatae (Labiatarum Genera et Species (1836)) is still the only comprehensive and global organization of the family. While he was clear about the integrity of the overall family, he was less confident about his organization of Salvia, the largest genus in Labiatae (also called Lamiaceae). Based on his own philosophy of classification, he wrote that he "ought to have formed five or six genera" out of Salvia. In the end, he felt that the advantage in placing a relatively uniform grouping in one genus was "more than counterbalanced by the necessity of changing more than two hundred names." At that time there were only 291 known Salvia species.
Subdivision.
Bentham eventually organized Salvia into twelve sections (originally fourteen), based on differences in corolla, calyx, and stamens. These were placed into four subgenera that were generally divided into Old World and New World species:
Subgenus Salvia: Old World (Sections: Hymenosphace, Eusphace, Drymosphace)
Subgenus Sclarea: Old World (Sections: Horminum, Aethiposis, Plethiosphace)
Subgenus Calosphace: New World (Section: Calosphace)
Subgenus Leonia: Old and New World (Sections: Echinosphace, Pycnosphace, Heterosphace, Notiosphace, Hemisphace)
His system is still the most widely studied classification of Salvia, even though more than 500 new species have been discovered since his work. Other botanists have since offered modified versions of Bentham's classification system, while botanists in the last hundred years generally do not endorse Bentham's system.
It was long assumed that Salvia's unusual pollination and stamen structure had evolved only once, and that therefore Salvia was monophyletic, meaning that all members of the genus evolved from one ancestor. However, the immense diversity in staminal structure, vegetative habit, and floral morphology of the species within Salvia has opened the debate about its infrageneric classifications.
Phylogenetic analyses.
Through DNA sequencing, Salvia was shown to not be monophyletic but to consist of three separate clades (Salvia clades I-III) each with different sister groups. They also found that the staminal lever mechanism evolved at least two separate times, through convergent evolution. Walker and Sytsma (2007) clarified this parallel evolution in a later paper combining molecular and morphological data to prove three independent lineages of the Salvia lever mechanism, each corresponding to a clade within the genus. It is surprising to see how similar the staminal lever mechanism structures are between the three lineages, so Salvia proves to be an interesting but excellent example of convergent evolution.
Walker and Sytsma (2007) also addressed the question of whether Salvia is truly polyphyletic or just paraphyletic within the tribe Mentheae. To make Salvia monophyletic would require the inclusion of 13 species from Rosmarinus, Perovskia, Dorystaechas, Meriandra, and Zhumeria genera. The information attained by Walker and Sytsma (2007) supporting the three independent origins of the staminal lever indicate that Salvia is not the case where 13 species (currently not members of the genus) are actually members of Salvia but underwent character reversals?in other words, Salvia is paraphyletic. Instead, Salvia is defined by its convergent character of distinct staminal evolution that proves its polyphyly.
The description of individual species within Salvia has undergone constant revision. Many species are similar to each other, and many species have varieties that have been given different specific names. There have been as many as 2,000 named species and subspecies. Over time, the number has been reduced to less than a thousand. A modern and comprehensive study of Salvia species was done by Gabriel Alziar, in his Catalogue Synonymique des Salvia du Monde (1989) (World Catalog of Salvia Synonyms). He found that the number of distinct species and subspecies could be reduced to less than 700.
Selected species and their uses.
Main article: List of Salvia species.
Many species are used as herbs, as ornamental plants (usually for flower interest), and sometimes for their ornamental and aromatic foliage. The Plant List has 986 accepted species names. A selection of some well known species is below.
Salvia apiana is the white sage sacred to a number of U.S. Native American Peoples, and used by some tribes in their ceremonies.
Salvia cacaliifolia is the blue wine sage or Guatemalan sage blooming with many pure gentian-blue flowers.
Salvia divinorum, or diviner's sage, is sometimes cultivated for psychedelic drug effects; the legality of its use is under review in some US states.
Salvia elegans, the pineapple sage, is widely grown as an ornamental shrub or sub-shrub, with pineapple scented leaves.
Salvia fruticosa, called Greek sage or just sage is commonly grown and harvested as an alternative to common sage.
Salvia hispanica, commonly known as chia, produces edible seeds which are high in protein and in the omega-3 fatty acid, ?-linolenic acid (ALA).
Salvia leucantha, Mexican bush sage or woolly sage, is grown as an ornamental in warm climates for its drooping flower heads, with white flowers emerging from furry blue or purple bracts.
Salvia microphylla from Mexico, sometimes called baby sage, is a small shrub grown extensively for its red (sometimes pink or white) flowers, and its fruit scented leaves.
Salvia miltiorrhiza, Chinese, Red sage, Danshen medicinal herb.
Salvia nemorosa, Woodland sage, ornamental
Salvia officinalis, or common sage is used widely in cooking, as an ornamental and landscape plant, and in herbal medicine.
Salvia sclarea, clary or clary sage, is grown as an ornamental and to some extent for perfume oils.
Salvia splendens or scarlet sage is a popular ornamental bedding or pot plant.
Salvia guaranitica or 'hummingbird sage' is grown as an ornamental flower.
Salvia species are used as food plants by the larvae of some Lepidoptera (butterfly and moth) species including the bucculatricid leaf-miner Bucculatrix taeniola which feeds exclusively on the genus and the Coleophora case-bearers C. aegyptiacae, C. salviella (both feed exclusively on S. aegyptiaca), C. ornatipennella and C. virgatella (both recorded on S. pratensis).
Etymology.
The name Salvia "salviya" derives from the Latin salvere ("to feel well and healthy, health, heal"), the verb related to salus (health, well-being, prosperity or salvation); referring to the herb's healing properties. Pliny the Elder was the first author known to describe a plant called "Salvia" by the Romans, likely describing the type species for the genus Salvia, Salvia officinalis.
The common modern English name sage derives from Middle English sawge, which was borrowed from Old French sauge, and like the botanical name, stems from Latin salvere. When used without modifiers, the name 'sage' generally refers to Salvia officinalis ("common sage" or "culinary sage"); however, it is used with modifiers to refer to any member of the genus. The ornamental species are commonly referred to by their genus name Salvia.

167.All the King's Men by Robert Penn Warren.
All the King's Men is a novel by Robert Penn Warren first published in 1946. Its title is drawn from the nursery rhyme Humpty Dumpty. In 1947 Warren won the Pulitzer Prize for All the King's Men. It was adapted for film in 1949 and 2006; the 1949 version won the Academy Award for Best Picture. It is rated the 36th greatest novel of the 20th century by Modern Library, and it was chosen as one of TIME magazine's 100 best novels since 1923.
Plot.
All the King's Men portrays the dramatic political rise and governorship of Willie Stark, a cynical populist in the American South during the 1930s. The novel is narrated by Jack Burden, a political reporter who comes to work as Governor Stark's right-hand man. The trajectory of Stark's career is interwoven with Jack Burden's life story and philosophical reflections: "the story of Willie Stark and the story of Jack Burden are, in one sense, one story."
The novel evolved from a verse play that Warren began writing in 1936 entitled Proud Flesh. One of the characters in Proud Flesh was named Willie Talos, in reference to the brutal character Talus in Edmund Spenser's late 16th century work The Faerie Queene.
The version of All the King's Men edited by Noel Polk (ISBN 0-15-100610-5) uses the name "Willie Talos" for the Boss as originally written in Warren's manuscript, and is known as the "restored version" for using this name as well as printing several passages removed from the original edit.
Warren claimed that All the King's Men was "never intended to be a book about politics."
Themes and imagery.
One central motif of the novel is that all actions have consequences, and that it is impossible for an individual to stand aloof and be a mere observer of life, as Jack tries to do (first as a graduate student doing historical research and later as a wisecracking newspaperman). In the atmosphere of the 1930s, whole populations seemed to abandon responsibility by living vicariously through messianic political figures like Willie Stark. Thus, Stark fulfills the wishes of many of the characters, or seems to do so. For instance, his faithful bodyguard Sugar-Boy, who stutters, loves Stark because "the b-boss could t-talk so good"; Jack Burden cannot bring himself to sleep with Anne Stanton, whom he loves, but Stark does so; and so on. (It is in this sense that the characters are "all the king's men"; other than borrowing this familiar phrase, the title has nothing to do with the story of Humpty Dumpty. The title is possibly derived from the motto of Huey P. Long, whose life was similar to that of Willie Stark, "Every Man a King".) But this vicarious achievement will eventually fail; ultimately Jack realizes that one must "go out of history into history and the awful responsibility of Time."
The novel explores conceptions of Calvinist theology, such as original sin ("Man is conceived in sin and born in corruption, and he passeth from the stink of the dydie to the stench of the shroud," says Willie when told that no adverse information about an opponent would be likely to be found. "There's always something"); and total depravity ("You got to make good out of bad," says Willie when his ruthless methods are criticized. "That's all there is to make it with.") Jack discovers that no man is invulnerable to sin under the right circumstances, and thus his search for dirt on the judge begins with questions as to what circumstances would cause one to do wrong. Jack, Willie, and Adam all abandon idealism when they realize that nobody is pure and unblemished.
Another motif in the novel is the "Great Twitch." When Jack Burden unexpectedly discovers that the love of his life, Anne Stanton, has been sleeping with Governor Willie Stark, he impulsively jumps in his car and drives to California to obtain some distance from the situation. Jack's description of his trip contains overt and indirect references to the notion of Manifest Destiny, which becomes somewhat ironic when he comes back from it believing in the "Great Twitch."
The "Great Twitch" is a particular brand of nihilism that Jack embraces during this journey westward: "all the words we speak meant nothing and there was only the pulse in the blood and the twitch of the nerve, like a dead frog's leg in the experiment when the electric current goes through." On his way back from California, Jack gives a ride to an old man who has an involuntary facial twitch. This image becomes for him the encapsulating metaphor for the idea that "all life is but the dark heave of blood and the twitch of the nerve." In other words, life is without meaning; everything is motivated by some inborn reflex action and nobody is responsible for their choices or even their own destiny. (The concept is brought to life for Jack when he witnesses a lobotomy performed by Adam Stanton.) The emotional distance permitted by this revelation releases Jack from his own frustration stemming from the relationship between Anne Stanton and his boss, and allows him to return to circumstances which were previously unbearable.
Subsequent events (including the tragic deaths of Governor Stark, Jack's lifelong friend Adam Stanton, and Judge Irwin, Jack's father) convince Jack that the revelation of the "Great Twitch" is an insufficient paradigm to explain what he has seen of history. "[H]e saw that though doomed, [his friends] had nothing to do with any doom under the godhead of the Great Twitch. They were doomed, but they lived in the agony of will." Ultimately, he grows to accept some responsibility for his part in the destruction of his friends' lives.
The book also touches on Oedipal themes, as Jack discovers his father's true identity after having caused his death.
The theme of one's father's identity and its effects on one's own sense of identity is explored twice in the novel, first through Adam and Anne's painful discovery that their father (the late Governor Stanton) once assisted in the cover-up of a bribery scandal. Then Jack discovers that his biological father is Judge Irwin, not, as he previously believed, "the Scholarly Attorney." In each case, the discovery catalyzes an upheaval in the character's moral outlook.
Time is another of the novel's thematic fascinations. The idea that every moment in the past contains the seeds of the future is constantly explored through the novel's non-chronological narrative, which reveals character continuities and thematic connections across different time periods.
Characters.
Willie Stark.
The central character of Willie Stark (often simply referred to as "the Boss") undergoes a radical transformation from an idealistic lawyer and weak gubernatorial candidate into a charismatic and extraordinarily powerful governor. In achieving this office Stark comes to embrace various forms of corruption and builds an enormous political machine based on patronage and intimidation. His approach to politics earns him many enemies in the state legislature, but does not detract from his popular appeal among many of his constituents, who respond with enthusiasm to his fiery populist manner.
Stark's character is often thought to be inspired by the life of Huey P. Long, former governor of Louisiana and that state's U.S. senator in the mid-1930s. Huey Long was at the zenith of his career when he was assassinated in 1935; just a year earlier, Robert Penn Warren had begun teaching at Louisiana State University. Stark, like Long, is shot to death in the state capitol building by a physician. The title of the book possibly came from Long's motto, "Every Man a King."
In his introduction to the Modern Library edition, Warren denied that the book should be read as either praise for Huey Long or praise for his assassination. However, Warren did not deny that Long served as an influence or inspiration for Stark:
One of the unfortunate characteristics of our time is that the reception of a novel may depend on its journalistic relevance. It is a little graceless of me to call this characteristic unfortunate, and to quarrel with it, for certainly the journalistic relevance of All the King's Men had a good deal to do with what interest it evoked. My politician hero, whose name, in the end, was Willie Stark, was quickly equated with the late [US] Senator Huey P. Long....
This equation led, in different quarters, to quite contradictory interpretations of the novel. On one hand, there were those who took the thing to be a not-so-covert biography of, and apologia for, Senator Long, and the author to be not less than a base minion of the great man. There is really nothing to reply to this innocent boneheadedness or gospel-bit hysteria. As Louis Armstrong is reported to have said, there's some folks that, if they don't know, you can't tell 'em... But on the other hand, there were those who took the thing to be a rousing declaration of democratic principles and a tract for the assassination of dictators. This view, though somewhat more congenial to my personal political views, was almost as wide of the mark. For better or worse, Willie Stark was not Huey Long. Willie [Stark] was only himself....
[T]he difference between the person Huey P. Long and the fiction Willie Stark, may be indicated by the fact that in the verse play [Proud Flesh] the name of the politician was Talos ? the name of the brutal, blank-eyed 'iron groom' of Spenser's Fairie Queene, the pitiless servant of the knight of justice. My conception grew wider, but that element always remained, and Willie Stark remained, in one way, Willie Talos. In other words, Talos is the kind of doom that democracy may invite upon itself. The book, however, was never intended to be a book about politics. Politics merely provided the framework story in which the deeper concerns, whatever their final significance, might work themselves out.
Jack Burden.
Jack Burden is the novel's narrator, a former student of history, newspaper columnist, and personal aide to Governor Willie Stark.
His narrative is propelled in part by a fascination with the mystery of Stark's larger-than-life character, and equally by his struggle to discover some underlying principle to make sense of all that has happened.
In narrating the story, Jack commingles his own personal story with the political story of Governor Stark. His telling of these two stories side by side creates a striking contrast between the personal and the impersonal. While his wry, detached, often humorous tone suggests an attempt to stand apart from the other characters' passions and intrigues, the highly personal content of his narrative suggests an awareness that he cannot truthfully remove himself and his own history from the story of Willie Stark, because his own story has paralleled and helped shape the tragic outcome of Stark's story.
Jack's overall character development might be roughly described as a journey away from an amoral perspective on human history as a chain of uncontrollable events, toward a belief in the fundamental interconnectedness of all of history. In other words, he might be said to trace a path from refusal to acceptance of personal responsibility. On the other hand, one defining trait that remains a constant throughout Jack's development is a passion for discovering the truth of history.
"And all times are one time, and all those dead in the past never lived before our definition gives them life, and out of the shadow their eyes implore us. That is what all of us historical researchers believe. And we love truth." [p. 342]
Anne Stanton.
Anne is Jack Burden's childhood sweetheart and the daughter of Willie Stark's political predecessor, Governor Stanton. Many of the novel's passages recounting Jack's life story revolve around memories of his relationship with Anne. Like many of Jack's friends, Anne disapproves of Willie Stark. However, in the wake of a devastating revelation regarding one of her father's moral lapses, she has an affair with Stark.
Adam Stanton.
Adam is a highly successful doctor, Anne Stanton's brother, and Jack Burden's childhood friend. Jack comes to view Adam Stanton as the polar opposite of Governor Stark, calling Adam "the man of idea" and Stark "the man of fact". Elsewhere, he describes Adam's central motivation as a deep need to "do good". Governor Stark invites Adam to be director of his pet project, a new hospital and medical center. The position initially strikes Adam as repugnant because of his revulsion to Stark's politics, but Jack and Anne ultimately persuade him to accept the invitation, essentially by removing his moral high ground. Adam's sense of violation as a result of his entanglement with Governor Stark proves violently tragic when he is informed by Lieutenant Governor Tiny Duffy that Stark has been sleeping with his sister. His pride demolished, Adam finds the Governor at the Capitol building and shoots him. To the extent that Willie Stark's story may have been loosely based on real-life events, the inspiration behind Adam Stanton's character would have been Dr. Carl Weiss.
Judge Irwin.
Judge Irwin is an elderly gentleman whom Jack has known since childhood, a man who is essentially a father-figure to him. Willie Stark assigns Jack the task of digging through Irwin's past to find something from the past with which Irwin can be blackmailed. Jack investigates thoroughly and finds what he is looking for: an incident many years ago when Judge Irwin took a bribe to dismiss a lawsuit against a fuel company, resulting in the personal destruction of a man named Mortimer Littlepaugh. Jack presents the incriminating evidence to Irwin, and before he has a chance to use it against him, Irwin commits suicide. Only at this point does Jack learn from his mother that Irwin was his father.
Cass Mastern.
One of Jack Burden's first major historical research projects revolves around the life of a 19th-century collateral ancestor, Cass Mastern, a man of high moral standards and a student at Transylvania College in Kentucky (Robert Penn Warren's native state). Cass's story, as revealed through his journals and letters, is essentially about a single betrayal of a friend that seems to ripple endlessly outward with negative consequences for many people. In studying this fragment of Civil War?era history, Jack begins to suspect (but cannot yet bring himself to accept) the idea that every event has unforeseen and unknowable implications, and that all actions and all persons are connected to other actions and other persons. Jack suggests that one reason he is unable to complete his dissertation on Cass's life is that perhaps "he was afraid to understand for what might be understood there was a reproach to him."
Cass Mastern and his moral challenges parallel those of Jack, something Jack does not understand when he is doing his doctoral dissertation on Mastern and one of the reasons that Burden abandons it. It is only at the end of the novel that Jack realizes this.

168.Crystal or Crystalline Solid.
A crystal or crystalline solid is a solid material whose constituents, such as atoms, molecules or ions, are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations.
The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word crystal is derived from the Ancient Greek word ?????????? (krustallos), meaning both ?ice? and ?rock crystal?, from ????? (kruos), "icy cold, frost".
Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Examples of polycrystals include most metals, rocks, ceramics, and ice. A third category of solids is amorphous solids, where the atoms have no periodic structure whatsoever. Examples of amorphous solids include glass, wax, and many plastics.
Crystal structure (microscopic)

The scientific definition of a "crystal" is based on the microscopic arrangement of atoms inside it, called the crystal structure. A crystal is a solid where the atoms form a periodic arrangement. (Quasicrystals are an exception, see below.)
Not all solids are crystals. For example, when liquid water starts freezing, the phase change begins with small ice crystals that grow until they fuse, forming a polycrystalline structure. In the final block of ice, each of the small crystals (called "crystallites" or "grains") is a true crystal with a periodic arrangement of atoms, but the whole polycrystal does not have a periodic arrangement of atoms, because the periodic pattern is broken at the grain boundaries. Most macroscopic inorganic solids are polycrystalline, including almost all metals, ceramics, ice, rocks, etc. Solids that are neither crystalline nor polycrystalline, such as glass, are called amorphous solids, also called glassy, vitreous, or noncrystalline. These have no periodic order, even microscopically. There are distinct differences between crystalline solids and amorphous solids: most notably, the process of forming a glass does not release the latent heat of fusion, but forming a crystal does.
A crystal structure (an arrangement of atoms in a crystal) is characterized by its unit cell, a small imaginary box containing one or more atoms in a specific spatial arrangement. The unit cells are stacked in three-dimensional space to form the crystal.
The symmetry of a crystal is constrained by the requirement that the unit cells stack perfectly with no gaps. There are 219 possible crystal symmetries, called crystallographic space groups. These are grouped into 7 crystal systems, such as cubic crystal system (where the crystals may form cubes or rectangular boxes, such as halite shown at right) or hexagonal crystal system (where the crystals may form hexagons, such as ordinary water ice).
Crystal faces and shapes.
As a halite crystal is growing, new atoms can very easily attach to the parts of the surface with rough atomic-scale structure and many dangling bonds. Therefore these parts of the crystal grow out very quickly (yellow arrows). Eventually, the whole surface consists of smooth, stable faces, where new atoms cannot as easily attach themselves.
Crystals are commonly recognized by their shape, consisting of flat faces with sharp angles. These shape characteristics are not necessary for a crystal?a crystal is scientifically defined by its microscopic atomic arrangement, not its macroscopic shape?but the characteristic macroscopic shape is often present and easy to see.
Euhedral crystals are those with obvious, well-formed flat faces. Anhedral crystals do not, usually because the crystal is one grain in a polycrystalline solid.
The flat faces (also called facets) of a euhedral crystal are oriented in a specific way relative to the underlying atomic arrangement of the crystal: They are planes of relatively low Miller index. This occurs because some surface orientations are more stable than others (lower surface energy). As a crystal grows, new atoms attach easily to the rougher and less stable parts of the surface, but less easily to the flat, stable surfaces. Therefore, the flat surfaces tend to grow larger and smoother, until the whole crystal surface consists of these plane surfaces. (See diagram on right.)
One of the oldest techniques in the science of crystallography consists of measuring the three-dimensional orientations of the faces of a crystal, and using them to infer the underlying crystal symmetry.
A crystal's habit is its visible external shape. This is determined by the crystal structure (which restricts the possible facet orientations), the specific crystal chemistry and bonding (which may favor some facet types over others), and the conditions under which the crystal formed.
Occurrence in nature.
Ice crystals.

Rocks.
By volume and weight, the largest concentrations of crystals in the earth are part of the Earth's solid bedrock.
Some crystals have formed by magmatic and metamorphic processes, giving origin to large masses of crystalline rock. The vast majority of igneous rocks are formed from molten magma and the degree of crystallization depends primarily on the conditions under which they solidified. Such rocks as granite, which have cooled very slowly and under great pressures, have completely crystallized; but many kinds of lava were poured out at the surface and cooled very rapidly, and in this latter group a small amount of amorphous or glassy matter is common. Other crystalline rocks, the metamorphic rocks such as marbles, mica-schists and quartzites, are recrystallized. This means that they were at first fragmental rocks like limestone, shale and sandstone and have never been in a molten condition nor entirely in solution, but the high temperature and pressure conditions of metamorphism have acted on them by erasing their original structures and inducing recrystallization in the solid state.
Other rock crystals have formed out of precipitation from fluids, commonly water, to form druses or quartz veins. The evaporites such as halite, gypsum and some limestones have been deposited from aqueous solution, mostly owing to evaporation in arid climates.
Ice.
Water-based ice in the form of snow, sea ice and glaciers is a very common manifestation of crystalline or polycrystalline matter on Earth. A single snowflake is typically a single crystal, while an ice cube is a polycrystal.
Organigenic crystals.
Many living organisms are able to produce crystals, for example calcite and aragonite in the case of most molluscs or hydroxylapatite in the case of vertebrates.
Polymorphism and allotropy.
Main articles: Polymorphism (materials science) and Allotropy.
The same group of atoms can often solidify in many different ways. Polymorphism is the ability of a solid to exist in more than one crystal form. For example, water ice is ordinarily found in the hexagonal form Ice Ih, but can also exist as the cubic Ice Ic, the rhombohedral ice II, and many other forms. The different polymorphs are usually called different phases.
In addition, the same atoms may be able to form noncrystalline phases. For example, water can also form amorphous ice, while SiO2 can form both fused silica (an amorphous glass) and quartz (a crystal). Likewise, if a substance can form crystals, it can also form polycrystals.
For pure chemical elements, polymorphism is known as allotropy. For example, diamond and graphite are two crystalline forms of carbon, while amorphous carbon is a noncrystalline form. Polymorphs, despite having the same atoms, may have wildly different properties. For example, diamond is among the hardest substances known, while graphite is so soft that it is used as a lubricant.
Polyamorphism is a similar phenomenon where the same atoms can exist in more than one amorphous solid form.
Crystallization.

Main articles: Crystallization and Crystal growth.
Crystallization is the process of forming a crystalline structure from a fluid or from materials dissolved in a fluid. (More rarely, crystals may be deposited directly from gas; see thin-film deposition and epitaxy.)
Crystallization is a complex and extensively-studied field, because depending on the conditions, a single fluid can solidify into many different possible forms. It can form a single crystal, perhaps with various possible phases, stoichiometries, impurities, defects, and habits. Or, it can form a polycrystal, with various possibilities for the size, arrangement, orientation, and phase of its grains. The final form of the solid is determined by the conditions under which the fluid is being solidified, such as the chemistry of the fluid, the ambient pressure, the temperature, and the speed with which all these parameters are changing.
Specific industrial techniques to produce large single crystals (called boules) include the Czochralski process and the Bridgman technique. Other less exotic methods of crystallization may be used, depending on the physical properties of the substance, including hydrothermal synthesis, sublimation, or simply solvent-based crystallization.
Large single crystals can be created by geological processes. For example, selenite crystals in excess of 10 meters are found in the Cave of the Crystals in Naica, Mexico. For more details on geological crystal formation, see above.
Crystals can also be formed by biological processes, see above. Conversely, some organisms have special techniques to prevent crystallization from occurring, such as antifreeze proteins.
Defects, impurities, and twinning.
Main articles: Crystallographic defect, Impurity, Crystal twinning and Mosaicity.
Two types of crystallographic defects. Top right: edge dislocation. Bottom right: screw dislocation.
An ideal crystal has every atom in a perfect, exactly repeating pattern. However, in reality, most crystalline materials have a variety of crystallographic defects, places where the crystal's pattern is interrupted. The types and structures of these defects may have a profound effect on the properties of the materials.
A few examples of crystallographic defects include vacancy defects (an empty space where an atom should fit), interstitial defects (an extra atom squeezed in where it does not fit), and dislocations (see figure at right). Dislocations are especially important in materials science, because they help determine the mechanical strength of materials.
Another common type of crystallographic defect is an impurity, meaning that the "wrong" type of atom is present in a crystal. For example, a perfect crystal of diamond would only contain carbon atoms, but a real crystal might perhaps contain a few boron atoms as well. These boron impurities change the diamond's color to slightly blue. Likewise, the only difference between ruby and sapphire is the type of impurities present in a corundum crystal.
Twinned pyrite crystal group.
In semiconductors, a special type of impurity, called a dopant, drastically changes the crystal's electrical properties. Semiconductor devices, such as transistors, are made possible largely by putting different semiconductor dopants into different places, in specific patterns.
Twinning is a phenomenon somewhere between a crystallographic defect and a grain boundary. Like a grain boundary, a twin boundary has different crystal orientations on its two sides. But unlike a grain boundary, the orientations are not random, but related in a specific, mirror-image way.
Mosaicity is a spread of crystal plane orientations. A mosaic crystal is supposed to consist of smaller crystalline units that are somewhat misaligned with respect to each other.
Chemical bonds.
Crystalline structures occur in all classes of materials, with all types of chemical bonds. Almost all metal exists in a polycrystalline state; amorphous or single-crystal metals must be produced synthetically, often with great difficulty. Ionically bonded crystals can form upon solidification of salts, either from a molten fluid or upon crystallization from a solution. Covalently bonded crystals are also very common, notable examples being diamond, silica, and graphite. Polymer materials generally will form crystalline regions, but the lengths of the molecules usually prevent complete crystallization. Weak van der Waals forces can also play a role in a crystal structure; for example, this type of bonding loosely holds together the hexagonal-patterned sheets in graphite.

Quasicrystals.
The material Ho-Mg-Zn forms quasicrystals, which can take on the macroscopic shape of a dodecahedron. (Only a quasicrystal, not a normal crystal, can take this shape.) The edges are 2mm long.
Main article: Quasicrystal.
A quasicrystal consists of arrays of atoms that are ordered but not strictly periodic. They have many attributes in common with ordinary crystals, such as displaying a discrete pattern in x-ray diffraction, and the ability to form shapes with smooth, flat faces.
Quasicrystals are most famous for their ability to show five-fold symmetry, which is impossible for an ordinary periodic crystal (see crystallographic restriction theorem).
The International Union of Crystallography has redefined the term "crystal" to include both ordinary periodic crystals and quasicrystals ("any solid having an essentially discrete diffraction diagram").
Quasicrystals, first discovered in 1982, are quite rare in practice. Only about 100 solids are known to form quasicrystals, compared to about 400,000 periodic crystals measured to date. The 2011 Nobel Prize in Chemistry was awarded to Dan Shechtman for the discovery of quasicrystals.
Special properties from anisotropy.
See also: Crystal optics.
Crystals can have certain special electrical, optical, and mechanical properties that glass and polycrystals normally cannot. These properties are related to the anisotropy of the crystal, i.e. the lack of rotational symmetry in its atomic arrangement. One such property is the piezoelectric effect, where a voltage across the crystal can shrink or stretch it. Another is birefringence, where a double image appears when looking through a crystal. Moreover, various properties of a crystal, including electrical conductivity, electrical permittivity, and Young's modulus, may be different in different directions in a crystal. For example, graphite crystals consist of a stack of sheets, and although each individual sheet is mechanically very strong, the sheets are rather loosely bound to each other. Therefore, the mechanical strength of the material is quite different depending on the direction of stress.
Not all crystals have all of these properties. Conversely, these properties are not quite exclusive to crystals. They can appear in glasses or polycrystals that have been made anisotropic by working or stress?for example, stress-induced birefringence.
Crystallography.
Main article: Crystallography.
Crystallography is the science of measuring the crystal structure (in other words, the atomic arrangement) of a crystal. One widely used crystallography technique is X-ray diffraction. Large numbers of known crystal structures are stored in crystallographic databases.
