Looks at Leonardo da Vinci love of nature and how it inspired many of his ideas.

An introduction to Leonardo da Vinci's genius focusing on his famous notebook sketches and the modern inventions they predicted. In 1781, Thomas Paine came up with a model for a single-span bridge; in 1887, Adolf Eugen Fick made the first pair of contact lenses; and in 1907, Paul Cornu built the first helicopter. But Leonardo da Vinci thought of all these ideas more than five hundred years ago! At once an artist, inventor, engineer, and scientist, da Vinci wrote and drew detailed descriptions of what would later become hang gliders, automobiles, robots, and much more. In Neo Geo, Gene Barretta cleverly shows how Leonardo's ideas—many inspired by his love of nature—foreshadowed modern inventions, offering a window into the future.

This book analyzes Leo Strauss's writings on political violence, considering also what he taught in the classroom on this subject.

What do record players, batteries, and movie cameras have in common? All these devices were created by the man known as The Wizard of Menlo Park: Thomas Edison. Edison is most famous for inventing the incandescent lightbulb, but at his landmark laboratories in Menlo Park & West Orange, New Jersey, he also developed many other staples of modern technology. Despite many failures, Edison persevered. And good for that, because it would be very difficult to go through a day without using one of his life-changing inventions. In this enlightening book, Gene Barretta enters the laboratories of one of America's most important inventors.

This provocative book examines the teachings of political theorist Leo Strauss and the ways in which they have been appropriated, or misappropriated, by senior policymakers.

The truth is out: we’re not alone in the universe. The arrival of a member of the Arkonide race has sent the Earth spiraling even further into chaos. Deep in the Gobi Desert, the astronaut Perry Rhodan stands his ground as hostile troops surround the new utopia he’s trying to build for all of humanity. But when the gravely ill alien’s condition worsens, there is no choice but to send him out for treatment—no matter the risk. Meanwhile, Sid, John Marshall, and Sue are on the run, wrestling with newly discovered superhuman powers and ominous threats that seem to lurk in the shadows. In a world of political and economic strife, can a handful of ordinary heroes survive and make a difference to the planet’s future? Rhodan doesn’t doubt that mankind is destined for the stars. But with so many obstacles in their path, the road there won’t be easy...

A probing study that demystifies the common portrayal of Leo Strauss as the inspiration for American neo-conservativism by tracing his philosophy to its German Jewish roots.
