After a few billion years of bearing witness to life on Earth, of watching one hundred billion humans go about their day-to-day lives, of feeling unbelievably lonely, and of hearing its own story told by others, The Milky Way would like a chance to speak for itself. All one hundred billion stars and fifty undecillion tons of gas of it. It all began some thirteen billion years ago, when clouds of gas scattered through the universe's primordial plasma just could not keep their metaphorical hands off each other.

Qui aurait imaginé, il y a vingt ans à peine, qu'un smartphone saurait reconnaître un visage ou qu'on guérirait l'hémophilie par thérapie génique? Que des robots pilotés depuis la Terre sillonneraient la planète rouge ou qu'on verrait le cerveau en action grâce à l'IRM? Les révolutions scientifiques bouleversent notre quotidien sans que nous en ayons toujours conscience : c'est à ce récit exaltant que nous invite ce livre audio.

The Big Bang is all but dead, and we do not yet know what will replace it. Our universe's "beginning" is at an end. What does this have to do with us here on Earth? Our lives are about to be dramatically shaken again - as altered as they were with the invention of the clock, the steam engine, the railroad, the radio and the Internet.

Discover the science behind the most popular sci-fi franchise of all time. Capturing the imagination and hearts of crowds worldwide, Star Wars is a fantastic feat of science fiction and fantasy. We marvel at the variety of creatures and technology and the mystery behind the force. But how much of the Star Wars world is rooted in reality? Could we see some of the extraordinary inventions materialize in our world?

On 12th April 1981 a revolutionary new spacecraft blasted off from Florida on her maiden flight. NASA's Space Shuttle Columbia was the most advanced flying machine ever built - the high watermark of post-war aviation development. A direct descendant of the record-breaking X-planes the likes of which Chuck Yeager had tested in the skies over the Mojave Desert, Columbia was a winged rocket plane, the size of an airliner, capable of flying to space and back before being made ready to fly again.

This course guides listeners through the sights of the naked- eye sky, wherein we directly witness the effects of the turning and revolving of the Earth, the artistry painted by the human mind using the sky and stars, and how the view changes with time and with our place on the planet.

In his phenomenal bestseller A Brief History of Time, Stephen Hawking literally transformed the way we think about physics, the universe, reality itself. In these thirteen essays and one remarkable extended interview, the man widely regarded as the most brilliant theoretical physicist since Einstein returns to reveal an amazing array of possibilities for understanding our universe.

Classical Mythology of the Constellations is a stargazer's guide to the wondrous stories of the gods, heroes, and monsters that populate the night sky. As long as humans have lived on Earth, they have gazed up at the starry sky with fascination and longing. For the ancient Greeks and Romans, the Sun, Moon, and Earth were gods. The stars beyond our Solar System, however, represented heroes, animals, and monsters that the gods placed in the sky after their death.

Humanity has long looked to the sky and marveled at the world around us. We've wondered why the world is the way it is and whether it has to be that way. And we dream of a time when we have developed a theory of everything—a theory that answers all questions. Einstein's Unfinished Dream explores the cutting-edge research of modern particle physicists that pushes us slowly towards a theory of everything....

David K. Stumpf demystifies the intercontinental ballistic missile program that was conceived at the end of the Eisenhower administration as a key component of the US nuclear strategy of massive retaliation. Although its nuclear warhead may have lacked power relative to that of the Titan II, the Minuteman more than made up for this in terms of numbers and readiness to launch - making it the ultimate ICBM.

Instruments of modern physics can measure the energies of the electromagnetic spectrum, but these energies only account for roughly 4 percent of the total identifiable mass-energy of the universe. What makes up the remaining 96%? In this scientifically based yet accessible analysis, Yury Kronn, Ph.D., explores the nature of the remaining 96% of the universe’s mass-energies. Contemporary science calls this mass energy “dark matter,” and the ancients called it life force, prana, or chi.

A respected physics professor and author breaks down the great debate over the big bang and the continuing quest to understand the fate of the universe.

Scientists have been searching for aliens in our solar system and beyond, but have not yet found evidence that life exists beyond Earth. SETI, the Search for Extraterrestrial Intelligence, has been scanning the stars for alien radio beacons for 50 years. Radio and TV broadcasts have been leaking from Earth’s atmosphere for over a century, and these traveling time capsules could eventually reach a broader audience than ever imagined. Neil and Lynne review the methods used to locate aliens and discuss what to do if you’re ever abducted.

Galileo’s Dialogue Concerning the Two Chief World Systems compares the Copernican or Heliocentric system with the Ptolemaic or Peripatetic, system of the cosmos. Published in Florence in 1632, it resulted in him being tried before the Inquisition. Using the dialogue form, Galileo masterfully shows the truth of the Copernican system that the Earth revolves around the Sun. The Dialogue is one of the most important treatises ever written. A work of supreme clarity and accessibility, it remains as accessible now as when it was published.

Living busily on Planet Earth, we rarely remember that we actually inhabit only a miniscule part of the universe. In The Planets and the Solar System, Jen Green paints the wider picture, and takes us on a journey across billions of kilometers in our galaxy, from our Sun to near and distant planets. Some, like Mercury, have a molten core surrounded with crust and spins quickly; Jupiter, on the other hand, is a big ball of gas.

On January 15, 2009, a US Airways Airbus A320 had just taken off from LaGuardia Airport in New York when a flock of Canada Geese collided with it, destroying both of its engines. The plane's pilot, Chesley "Sully" Sullenberger, managed to glide it to a safe landing in the Hudson River. It was an instant media sensation---the "Miracle on the Hudson"---and Captain Sully was the hero. But how much of the success of this dramatic landing can actually be credited to the genius of the pilot?

There seems to be evidence to suggest that our world and everything in it are only ghostly images: projections from a level of reality so beyond our own that the real reality is literally beyond both space and time. The main architect of this astonishing idea is one of the world’s most eminent thinkers - physicist David Bohm, a protégé of Einstein’s. In this executive summary, Chuck gives a current perspective on some of the areas that define our reality.

In a drastic reevaluation of astronomy observations from Mahabharata, using high-tech tools of modern astronomy and low-tech tools of the logic of scientific discovery, Nilesh Oak’s extraordinary book presents ordinary theory of astronomy observations that would lead to a quantum jump in our understanding of the Mahabharata War

The universe is a vast, mysterious, and incredibly cool place. It’s filled with things so strange and wonderful they can make your head spin. From the tiniest particles buzzing around beneath the surface of reality to the largest structures stretching across billions of light-years, the cosmos is packed with surprises. And the more we learn, the more we realize just how much we don’t know. When you glance up at the night sky, you’re not just looking at stars. You’re peering into the deep past, through millions or even billions of years.

Carl Edward Sagan (November 9, 1934-December 20, 1996), born in Brooklyn, NY, was an American astronomer and astrophysicist. His best-known scientific contribution was his research on the possibility of extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by exposure to light. The following is a lecture Sagan gave in 1977 during which he discussed the place, scale and geometry of earth–the third planet from the Sun, formed 4.5 billion years ago–in our solar system.
