Written over a period of thirty-five years, these essays explore the topics of causation, time, fate, determinism, natural teleology, different conceptions of the human soul, the idea of the highest good and the human significance of leisure. While most of the essays take as their starting-point some theme in Ancient Greek philosophy, they are meant not as exegesis but as distinctive and independent contributions to live philosophizing. Written with clarity, precision without technicality, and philosophical imagination, they will engage a wide range of readers, including scholars and students of Ancient Greek philosophy and others working on more contemporary analytical concerns.

For all of you who break out in a sweat at the thought of thermodynamics, or freeze up at the mention of quantum mechanics, like a bolt from the blue, INSTANT PHYSICS will zap you through the fascinating history of our most basic, yet baffling, science. From the thousand-year search for proof of the existence of the ever-elusive atom to the varied and heated arguments behind the big bang theory, INSTANT PHYSICS answers all the heavy questions with a light touch. You'll learn:* How the Greek philosophers used the sledgehammer of mathematics to break apart the mysteries of the physical universe.* Why gravity is a "romantic" force.* How to tell the difference between a gluon, a meson, and a quark, even if you can't see them.INSTANT PHYSICS is crammed with special features, including chapter summaries, who's who lists, biographical and historical tidbits, and a host of illustrations, photos, equations, diagrams, and drawings.

Cosmology is the study of the origin, size, and evolution of the entire universe. Every culture has developed a cosmology, whether it be based on religious, philosophical, or scientific principles. In this book, the evolution of the scientific understanding of the Universe in Western tradition is traced from the early Greek philosophers to the most modern 21st century view. After a brief introduction to the concept of the scientific method, the first part of the book describes the way in which detailed observations of the Universe, first with the naked eye and later with increasingly complex modern instruments, ultimately led to the development of the "Big Bang" theory. The second part of the book traces the evolution of the Big Bang including the very recent observation that the expansion of the Universe is itself accelerating with time.

Advance Praise for Gravity's Arc "A beautifully written exposition of the still mysterious force that holds our universe together--and the even more mysterious dark twin that may blow it apart." --Joshua Gilder, coauthor of Heavenly Intrigue "A lucid book as up-to-date as the effect of gravity on the bones of astronauts." --Denis Brian, author of The Unexpected Einstein How did they do it? How did one of the greatest geniuses who ever lived retard the study of gravity for 2,000 years? How did a gluttonous tyrant with a gold nose revolutionize our view of the solar system? How could an eccentric professor shake the foundations of an entire belief system by dropping two objects from a tower? How did a falling apple turn the thoughts of a reclusive genius toward the moon? And how could a simple patent clerk change our entire view of the universe by imagining himself riding on a beam of light? In Gravity's Arc, you'll discover how some of the most colorful, eccentric, and brilliant people in history first locked, then unlocked the door to understanding one of nature's most essential forces. You'll find out why Aristotle's misguided conclusions about gravity became an unassailable part of Christian dogma, how Galileo slowed down time to determine how fast objects fall, and why Isaac Newton erased every mention of one man's name from his magnum opus Principia. You'll also figure out what Einstein meant when he insisted that space is curved, whether there is really such a thing as antigravity, and why some scientists think that the best way to get to outer space is by taking an elevator.

Rhetoric gives our words the power to inspire. But it's not just for politicians: it's all around us, whether you're buttering up a key client or persuading your children to eat their greens. You have been using rhetoric yourself, all your life. After all, you know what a rhetorical question is, don't you? In this updated edition of his classic guide, Sam Leith traces the art of argument from ancient Greece down to its many modern mutations. He introduces verbal villains from Hitler to Donald Trump - and the three musketeers: ethos, pathos and logos. He explains how rhetoric works in speeches from Cicero to Richard Nixon, and pays tribute to the rhetorical brilliance of AC/DC's "Back In Black". Before you know it, you'll be confident in chiasmus and proud of your panegyrics - because rhetoric is useful, relevant and absolutely nothing to be afraid of.
