When Ed White, clad in his gleaming space suit with a large American flag on his left shoulder, eased himself outside his Gemini spacecraft in 1965, Americans had a new space hero. They also learned a new acronym: EVA, short for extravehicular activity, more commonly known as "spacewalking." Though few understood the tremendous risks White was taking in his twenty-two-minute space walk, Americans watched with immense pride and patriotism as White, tethered to Gemini 4, propelled himself around the spacecraft with a pressurized oxygen-fueled zip gun.

In Calculating the Cosmos, Ian Stewart presents an exhilarating guide to the cosmos, from our solar system to the entire universe. He describes the architecture of space and time, dark matter and dark energy, how galaxies form, why stars implode, how everything began, and how it's all going to end. He considers parallel universes, the fine-tuning of the cosmos for life, what forms extraterrestrial life might take, and the likelihood of life on Earth being snuffed out by an asteroid.

Does the universe embody beautiful ideas? Artists as well as scientists throughout human history have pondered this "beautiful question". With Nobel laureate Frank Wilczek as your guide, embark on a voyage of related discoveries, from Plato and Pythagoras up to the present. Wilczek's groundbreaking work in quantum physics was inspired by his intuition to look for a deeper order of beauty in nature.

Author Jim Holt explores the greatest metaphysical mystery of all: why is there something rather than nothing? This runaway best seller, which has captured the imagination of critics and the public alike, traces our latest efforts to grasp the origins of the universe. Holt adopts the role of cosmological detective, traveling the globe to interview a host of celebrated scientists, philosophers, and writers.

Space is a place of unparalleled possibility for humanity, and it's undergoing a revolution. A wave of companies led by gutsy entrepreneurs are unlocking opportunities that fire the imagination. No, it's not hotels on Mars or day trips to orbit (yet), but it's an awe-inspiring transformation driven by innovative technologies, creative approaches, hard work, and—for the first time—market forces.

Was könnte da der Sinn des Lebens sein? Der Wissenschaftsinfluencer Tim Vollert hat darauf eine faszinierende Antwort, und die liegt in der Physik. Auf seiner spannenden Reise vom Urknall bis zum Kältetod des Universums erklärt er nicht nur die Physik des Kosmos, sondern auch die Biologie hinter der Entstehung des Lebens.

In the 1940s and '50s, when the newly minted Jet Propulsion Laboratory needed quick-thinking mathematicians to calculate velocities and plot trajectories, they didn't turn to male graduates. Rather, they recruited an elite group of young women who, with only pencil, paper, and mathematical prowess, transformed rocket design, helped bring about the first American satellites, and made the exploration of the solar system possible.

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.

Spaceflight is notoriously dangerous. Beyond launch mishaps and equipment failures, astronauts face serious health problems from long-term weightlessness and high-energy radiation. Not to mention, the space environment is a near-perfect vacuum that can quickly kill anyone who is unprotected. Drawing on the hard-won insights of NASA astronauts and space researchers, this 12-lecture course presents the perils of spaceflight and what experts have done to make them survivable. It also deals with livability in space, including nutrition, sleep, environmental control, and personal hygiene.

During the early and most dangerous years of the cold war, a handful of Americans, led by President Dwight D. Eisenhower, revolutionized spying and warfare. In great secrecy and beyond the prying eyes of Congress and the press, they built exotic new machines that opened up the Soviet Union to surveillance and protected the United States from surprise nuclear attack. Secret Empire is the dramatic story of these men and their inventions, told in full for the first time.

One of the leading physicists of her generation, Dr. Chanda Prescod-Weinstein is also one of fewer than one hundred Black American women to earn a PhD from a department of physics. Her vision of the cosmos is vibrant, buoyantly nontraditional, and grounded in Black and queer feminist lineages. Dr. Prescod-Weinstein urges us to recognize how science, like most fields, is rife with racism, misogyny, and other forms of oppression. She lays out a bold new approach to science and society, beginning with the belief that we all have a fundamental right to know and love the night sky.

En octubre de 2017, científicos del observatorio Haleakala, en Hawái, detectaron un objeto interestelar en movimiento próximo a la Tierra. Primero fue catalogado de cometa, pero esta hipótesis fue descartada. Llamado "Oumuamua", "mensajero" o "explorador" en hawaiano, finalmente fue catalogado como asteroide, si bien su forma y su comportamiento diferían del resto de los asteroides y cometas de nuestro sistema solar. Cuanto más lo observaban los científicos, más extraño les parecía.

When and how did the universe begin? Why are we here? What is the nature of reality? Is the apparent “grand design” of our universe evidence of a benevolent creator who set things in motion—or does science offer another explanation? In The Grand Design, Stephen Hawking and Leonard Mlodinow present the most illuminating scientific thinking about these and other abiding mysteries of the universe, in nontechnical language marked by brilliance and simplicity.

In the aftermath of World War II, the United States accelerated the development of technologies that would give it an advantage over the Soviet Union. Airpower, combined with nuclear weapons, offered a formidable check on Soviet aggression. In 1947, the United States Air Force was established. Meanwhile, scientists and engineers were pioneering a revolutionary new type of aircraft which could do what no other machine had ever done: reach mach 1 - a speed faster than the movement of sound - which pilots called "the demon."

For more than half a century, physicists and astronomers engaged in heated dispute over the possibility of black holes in the universe. The weirdly alien notion of a space-time abyss from which nothing escapes - not even light - seemed to confound all logic. This engrossing audiobook tells the story of the fierce black hole debates and the contributions of Einstein, Hawking, and other leading thinkers who completely altered our view of the universe.

Everything we now know about the universe - from the behavior of quarks to the birth of galaxies - has come from people who've been willing to ponder the unanswerable. And with the advent of modern science, great minds have turned to testing and experimentation rather than mere thought as a way of grappling with some of the universe's most vexing dilemmas. So what is our latest picture of some of the most inexplicable features of the universe? What still remains to be uncovered and explored by today's scientists?

I don’t think many people know that the moon is not actually a perfect sphere; it is in fact shaped slightly like a lemon with bulges on both sides. Or that a day on Mercury lasts longer than a year. These are just a few of the many interesting facts that you will discover about space in this audiobook. If you’re like me, anything space related will fascinate you; there is just something exciting about the big wide world out there beyond Earth, the many unknowns, and the interesting facts that are being discovered on a daily basis.

The Los Angeles Times headline screamed: Rocket Scientist Killed in Pasadena Explosion. The man known as Jack Parsons, a maverick rocketeer who helped transform a derided sci-fi plotline into actuality, was at first mourned as a scientific prodigy. But reporters soon uncovered a more shocking story: Parsons had been a devotee of the city’s occult scene.

A journey through life, the universe and everything. From what actually happened in the big bang to the accidental discovery of Post-it notes, science is packed with surprising discoveries. Did you know, for instance, that if you were to get too close to a black hole it would suck you up like a noodle (it's called spaghettification), why your keyboard is laid out in QWERTY (it's not to make it easier to type) or whether the invention of the wheel was less important to civilisation than the bag (think about it)? New Scientist does.

In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?
