History of the Peloponnesian War: Bk. 1-2


Thucydides
    He saw the rise of Athens to greatness under the inspired leadership of Pericles. In 430, the second year of the Peloponnesian War, he caught and survived the horrible plague which he described so graphically. Later, as general in 423 he failed to save Amphipolis from the enemy and was disgraced. He tells about this, not in volumes of self-justification, but in one sentence of his history of the war—that it befell him to be an exile for twenty years. He then lived probably on his property in Thrace, but was able to observe both sides in certain campaigns of the war, and returned to Athens after her defeat in 404. He had been composing his famous history, with its hopes and horrors, triumphs and disasters, in full detail from first-hand knowledge of his own and others.The war was really three conflicts with one uncertain peace after the first; and Thucydides had not unified them into one account when death came sometime before 396. His history of the first conflict, 431–421, was nearly complete; Thucydides was still at work on this when the war spread to Sicily and into a conflict (415–413) likewise complete in his awful and brilliant record, though not fitted into the whole. His story of the final conflict of 413–404 breaks off (in the middle of a sentence) when dealing with the year 411. So his work was left unfinished and as a whole unrevised. Yet in brilliance of description and depth of insight this history has no superior.The Loeb Classical Library edition of Thucydides is in four volumes.

Hippocratic Writings


Hippocrates - 1978
    His fame was such that many Greek medical writings became attributed to him. What they have in common is not dogma but, rather, constructive debate between one another. They also share a concern with meticulous observation and an insistence on physical, not supernatural, causation of illness. The writers were the pioneers of rational medicine; their ideas, dominant for centuries, still reveal to us the ideal of ethical practice, as well as the origins not just of Western medicine but of scientific method.This excellent selection of Hippocratic treatises shows the range of writing and thought. Some are technical works on embryology, surgery or anatomy; others are addressed to a lay audience; all are informed with the spirit of inquiry. G.E.R. Lloyd's authoritative introduction puts them into their contemporary context and assesses their later influence.

Einstein's Heroes: Imagining the World Through the Language of Mathematics


Robyn Arianrhod - 2004
    Einstein's Heroes takes you on a journey of discovery about just such a miraculous language--the language of mathematics--one of humanity's mostamazing accomplishments. Blending science, history, and biography, this remarkable book reveals the mysteries of mathematics, focusing on the life and work of three of Albert Einstein's heroes: Isaac Newton, Michael Faraday, and especially James Clerk Maxwell, whose work directly inspired the theory of relativity. RobynArianrhod bridges the gap between science and literature, portraying mathematics as a language and arguing that a physical theory is a work of imagination involving the elegant and clever use of this language. The heart of the book illuminates how Maxwell, using the language of mathematics in a newand radical way, resolved the seemingly insoluble controversy between Faraday's idea of lines of force and Newton's theory of action-at-a-distance. In so doing, Maxwell not only produced the first complete mathematical description of electromagnetism, but actually predicted the existence of theradio wave, teasing it out of the mathematical language itself. Here then is a fascinating look at mathematics: its colorful characters, its historical intrigues, and above all its role as the uncannily accurate language of nature.

Discourses, Books 3-4. The Enchiridion (Loeb Classical Library #218)


Epictetus - 1928
    Expelled with other philosophers by the emperor Domitian in 89 or 92 he settled permanently in Nicopolis in Epirus. There, in a school which he called 'healing place for sick souls', he taught a practical philosophy, details of which were recorded by Arrian, a student of his, and survive in four books of Discourses and a smaller Encheiridion, a handbook which gives briefly the chief doctrines of the Discourses. He apparently lived into the reign of Hadrian (117–138 CE).Epictetus was a teacher of Stoic ethics, broad and firm in method, sublime in thought, and now humorous, now sad or severe in spirit. How should one live righteously? Our god-given will is our paramount possession, and we must not covet others'. We must not resist fortune. Man is part of a system; humans are reasoning beings (in feeble bodies) and must conform to god's mind and the will of nature. Epictetus presents us also with a pungent picture of the perfect (Stoic) man.The Loeb Classical Library edition of Epictetus is in two volumes.

Imagining the Tenth Dimension: A New Way of Thinking about Time and Space


Rob Bryanton - 2006
    Ten dimensions? Most of us have barely gotten used to the idea that there are four.Using simple geometry and an easygoing writing style, author Rob Bryanton starts with the lower dimensions that we are all familiar with, then uses those concepts to build one layer upon another, ultimately arriving at a way of imagining the tenth dimension.Part scientific exploration, part philosophy, this unique book touches upon such diverse topics as dark matter, Feynman's "sum over paths", the quantum observer, and the soul. It is aimed at anyone interested in leading-edge theories about cosmology and the nature of reality, but it is not about mainstream physics. Rather, Imagining the Tenth Dimension is a mind-expanding exercise that could change the way you view this incredible universe in which we live.

Epitome of Copernican Astronomy and Harmonies of the World


Johannes Kepler - 1621
    This volume contains two of his most important works: The Epitome of Copernican Astronomy (books 4 and 5 of which are translated here) is a textbook of Copernican science, remarkable for the prominence given to physical astronomy and for the extension to the Jovian system of the laws recently discovered to regulate the motions of the Planets. Harmonies of the World (book 5 of which is translated here) expounds an elaborate system of celestial harmonies depending on the varying velocities of the planets.

Orestes and Other Plays


Euripides
    Ion vividly portrays the role of chance in human life and the dynamics of family relationships. In Orestes, the most popular of the tragedian's plays about the ancient world, Euripides explores the emotional consequences of Orestes' murder of his mother on the individuals concerned, and makes the tale resonate with advice to Athens about the threat to democracy posed by political pressure groups. The Suppliant Women is a commentary on the politics of empire, as the Athenian king Theseus decides to use force of arms rather than persuasion against Thebes. The Phoenician Women transforms the terrible conflict between Oedipus' sons into one of the most savage indictments of civil war in Western literature by highlighting the personal tragedy it brings.

Fermat's Enigma


Simon Singh - 1997
    xn + yn = zn, where n represents 3, 4, 5, ...no solution"I have discovered a truly marvelous demonstration of this proposition which this margin is too narrow to contain."With these words, the seventeenth-century French mathematician Pierre de Fermat threw down the gauntlet to future generations.  What came to be known as Fermat's Last Theorem looked simple; proving it, however, became the Holy Grail of mathematics, baffling its finest minds for more than 350 years.  In Fermat's Enigma--based on the author's award-winning documentary film, which aired on PBS's "Nova"--Simon Singh tells the astonishingly entertaining story of the pursuit of that grail, and the lives that were devoted to, sacrificed for, and saved by it.  Here is a mesmerizing tale of heartbreak and mastery that will forever change your feelings about mathematics.
