Richard Feynman, Nobel Prize winner for his work on the description and calculation of interactions between particles, was a genius of our time. Quantum physics theoretician, enfant terrible of the Manhattan project and ascerbic critic of the investigative committee of the American space shuttle, Feynman left a profound impression on modern physics. James Gleick, a former journalist at The New York Times and author of the best-selling Chaos Theory, tells how Feynman's ideas were formed and how he reinvented particle physics. Through this portrait, Gleick explores the nature of genius itself and provides insight about the fascination that it engenders.
Why don't sand dunes collapse? How does sand flow in an hourglass? How is it possible to empty a silo of all its wheat? What's a ceramic? The answer to all these questions can be found in the science of the complex organizations of matter, a science which is pluridisciplinary. Étienne Guyon, head of the École Normale Supérieure, and Jean-Paul Troadec, a researcher, present the characteristics of grain matter, the rules by which it is organized (in both crystal and fluid) as well as its movements (in silos as in avalanches).
From the physics of particules to astronomy, from chemistry to biology, chaos is present in most scientific fields. Three specialists of this subject have undertaken, through many examples, to extract chaos from the scientific world in order to show how strong is its hold on our daily lives.
This book is foremost a piece of scientific popularization. M. Cassé leads us on an historical stroll through physics. First we meet the ideas of Galileo and Newton. Then Einstein modifies the classical notions of time and space. Finally quantum mechanics revolutionize our sense of matter. On a deeper level, Cassé sees physics as an arena for debate on the nature of reality. This is why scientific discourse often tends toward reverie and poetic meditation, particularly when concerning itself with the void, a central notion for modern physics and the complex protagonist of Cassé's scientific journey.
Man has begun to realize one of his most ancient dreams: to overcome gravity, to conquer space, to explore the universe. André Lebeau sheds light on some of the stakes of this quest. By examining the logic of evolution which drives us to explore, and then to occupy, discovered continents, Lebeau traces the perspectives that the possible colonization of outer space opens to humanity. In so doing, he offers a new viewpoint on the dynamics of scientific and technological progress.
