DOWNLOAD EBOOKHow can something that grounds us and keeps us here on this earth be so invisible and mysterious? We’re not talking about anything abstract and undetectable. We’re talking about GRAVITY! Gravity is a force that affects everyone and everything. Gravity is something we can easily understand, even kids, especially if they have the right tools to teach them. Explore Gravity! With 25 Great Projects will introduce kids ages 6-9 to the basics of gravity, including concepts of matter, attraction, and gravitational pull. Projects include creating a working model of a scale to learn what “weight” really means and how it’s affected by gravity. By playing with various weights to make a marvelous mobile, readers learn about the center of balance and how martial artists use this knowledge to throw their weight around. All the projects in this book are easy to follow, require little adult supervision, and use commonly found household products, many from the recycling box! The fun facts, trivia, jokes, comics, and hands-on activities will help kids discover the captivating science of gravity. Furthermore, the informational text and hands-on activities will excite kids about STEM, the interrelated fields of science, technology, engineering, and math.

DOWNLOAD EBOOKAn ideal introduction to Einstein's general theory of relativity This unique textbook provides an accessible introduction to Einstein's general theory of relativity, a subject of breathtaking beauty and supreme importance in physics. With his trademark blend of wit and incisiveness, A. Zee guides readers from the fundamentals of Newtonian mechanics to the most exciting frontiers of research today, including de Sitter and anti-de Sitter spacetimes, Kaluza-Klein theory, and brane worlds. Unlike other books on Einstein gravity, this book emphasizes the action principle and group theory as guides in constructing physical theories. Zee treats various topics in a spiral style that is easy on beginners, and includes anecdotes from the history of physics that will appeal to students and experts alike. He takes a friendly approach to the required mathematics, yet does not shy away from more advanced mathematical topics such as differential forms. The extensive discussion of black holes includes rotating and extremal black holes and Hawking radiation. The ideal textbook for undergraduate and graduate students, Einstein Gravity in a Nutshell also provides an essential resource for professional physicists and is accessible to anyone familiar with classical mechanics and electromagnetism. It features numerous exercises as well as detailed appendices covering a multitude of topics not readily found elsewhere. Provides an accessible introduction to Einstein's general theory of relativity Guides readers from Newtonian mechanics to the frontiers of modern research Emphasizes symmetry and the Einstein-Hilbert action Covers topics not found in standard textbooks on Einstein gravity Includes interesting historical asides Features numerous exercises and detailed appendices Ideal for students, physicists, and scientifically minded lay readers Solutions manual (available only to teachers)

DOWNLOAD EBOOKGravity is a mystery. Objects fall to the ground as if pulled by an unseen hand. Galileo was the first person to discover how falling works, but failed to ask why. Kepler deciphered the laws of planetary motion but missed the meaning of his own discoveries. Newton ignited the Enlightenment when he found the connection between matter and gravity, and gave us the tools to measure orbital mechanics. But Newton was disappointed with his own discoveries because the source of gravity lay hidden from him. Einstein discovered the connection between space and matter but his own equations masked the real source of gravity. He failed to understand that space is more than geometry. This book explores the energy of space and discovers that its structure completely defines gravity. Using simple mathematics and the achievements of Galileo, Kepler, Newton, and Einstein, the author constructs a new law of gravity that is defined by the size of the universe and its matter-energy content. Gone is Newton's awkward, arbitrary constant and Einstein's dependence on it. The force of gravity becomes the tendency for the Universe to reach perfect symmetry of space-energy. The Universe is self-regulating with its space-tension exactly balanced by its matter-energy. The Universe consists of only space-energy and the matter-energy that was derived from it. With space-energy revealed as the source of gravity, the author looks into the meaning of anti-gravity, and how we might achieve it.

DOWNLOAD EBOOKIt was all part of man's greatest adventure--landing men on the Moon and sending a rover to Mars, finally seeing the edge of the universe and the birth of stars, and launching planetary explorers across the solar system to Neptune and beyond. The ancient dream of breaking gravity's hold and taking to space became a reality only because of the intense cold-war rivalry between the superpowers, with towering geniuses like Wernher von Braun and Sergei Korolyov shelving dreams of space travel and instead developing rockets for ballistic missiles and space spectaculars. Now that Russian archives are open and thousands of formerly top-secret U.S. documents are declassified, an often startling new picture of the space age emerges: the frantic effort by the Soviet Union to beat the United States to the Moon was doomed from the beginning by gross inefficiency and by infighting so treacherous that Winston Churchill likened it to "dogs fighting under a carpet"; there was more than science behind the United States' suggestion that satellites be launched during the International Geophysical Year, and in one crucial respect, Sputnik was a godsend to Washington; the hundred-odd German V-2s that provided the vital start to the U.S. missile and space programs legally belonged to the Soviet Union and were spirited to the United States in a derring-do operation worthy of a spy thriller; despite NASA's claim that it was a civilian agency, it had an intimate relationship with the military at the outset and still does--a distinction the Soviet Union never pretended to make; constant efforts to portray astronauts and cosmonauts as "Boy Scouts" were often contradicted by reality; the Apollo missions to the Moon may have been an unexcelled political triumph and feat of exploration, but they also created a headache for the space agency that lingers to this day. This New Ocean is based on 175 interviews with Russian and American scientists and engineers; on archival documents, including formerly top-secret National Intelligence Estimates and spy satellite pictures; and on nearly three decades of reporting. The impressive result is this fascinating story--the first comprehensive account--of the space age. Here are the strategists and war planners; engineers and scientists; politicians and industrialists; astronauts and cosmonauts; science fiction writers and journalists; and plain, ordinary, unabashed dreamers who wanted to transcend gravity's shackles for the ultimate ride. The story is written from the perspective of a witness who was present at the beginning and who has seen the conclusion of the first space age and the start of the second.
