The Principia: Mathematical Principles of Natural Philosophy is Isaac Newton's monumental work, originally published in 1687. Known familiarly as the Principia, this text laid out in mathematical terms the principles of time, force, and motion that have guided the development of modern physical science.

Even after more than three centuries and the revolutions of Einsteinian relativity and quantum mechanics, Newtonian physics continues to account for many of the phenomena of the observed world. Newtonian celestial dynamics is still used to determine the orbits of our space vehicles.

This edition is a completely new translation, the first in 270 years, based on the third (1726) edition, the final revised version approved by Newton. It includes extracts from earlier editions, corrects errors found in previous versions, and replaces archaic English with contemporary prose and up-to-date mathematical forms.

Newton's principles describe acceleration, deceleration, and inertial movement; fluid dynamics; and the motions of the earth, moon, planets, and comets. A great work in itself, the Principia also revolutionized the methods of scientific investigation. It set forth the fundamental three laws of motion and the law of universal gravity, the physical principles that account for the Copernican system of the world as emended by Kepler, thus effectively ending controversy concerning the Copernican planetary system.

The illuminating Guide to the Principia by I. Bernard Cohen, along with his and Anne Whitman's translation, makes this preeminent work truly accessible for today's scientists, scholars, and students.

With the born storyteller's command of narrative and imaginative approach, Leonard Mlodinow vividly demonstrates how our lives are profoundly informed by chance and randomness and how everything from wine ratings and corporate success to school grades and political polls are less reliable than we believe.

By showing us the true nature of chance and revealing the psychological illusions that cause us to misjudge the world around us, Mlodinow gives us the tools we need to make more informed decisions. From the classroom to the courtroom and from financial markets to supermarkets, Mlodinow's intriguing and illuminating look at how randomness, chance, and probability affect our daily lives will intrigue, awe, and inspire.

From a brilliant new talent comes a riveting novel of chance, fate, and numbers, and one man's strange journey past the boundaries of the possible.

David Caine inhabits a world of obsession, rich rewards, and rapid, destructive downfalls. A compulsive gambler and brilliant mathematician prone to crippling epileptic seizures, he possesses the uncanny ability to calculate odds of any hand in the blink of an eye. But one night at an underground poker club, Caine makes a costly miscalculation, sending his life spinning out of control.

Desperate, he agrees to test an experimental drug with unnerving side effects: inexplicable visions of the past, present, and future. Unsure whether he's perceiving an alternate reality or suffering a psychotic breakdown, Caine embarks on a journey that stretches beyond the possible into the world of the improbable.

Gradually, he discovers the extent of his astonishing new ability -- but powerful, shadowy forces know Caine's secret. Now Caine must fight for his survival -- and his sanity.

Green Lion Press has prepared a new one-volume edition of T.L. Heath's translation of the thirteen books of Euclid's Elements. In keeping with Green Lion's design commitment, diagrams have been placed on every spread for convenient reference while working through the proofs; running heads on every page indicate both Euclid's book number and proposition numbers for that page; and adequate space for notes is allowed between propositions and around diagrams.

The all-new index has built into it a glossary of Euclid's Greek terms. Heath's translation has stood the test of time, and, as one done by a renowned scholar of ancient mathematics, it can be relied upon not to have inadvertently introduced modern concepts or nomenclature. We have excised the voluminous historical and scholarly commentary that swells the Dover edition to three volumes and impedes classroom use of the original text. The single volume is not only more convenient, but less expensive as well.
