Dr. Michael Guillen, a best-selling author, Emmy award-winning journalist and former physics instructor at Harvard, used to be an atheist ― until science changed his mind. Once of the opinion that people of faith are weak, small-minded folks who just don’t understand science, Dr. Guillen ultimately concluded that not only does science itself depend on faith, but faith is actually the mightiest power in the universe.

Certaines ne sont visibles qu'avec les plus grands télescopes. D'autres brillent si intensément qu'elles peuplent nos mythes depuis l'aube de l'humanité. Elles sont désignées par de mystérieuses références ou portent haut leur nom - Alcyone, Monocerotis, Ras Algethi, Thuban, Zeta Ophiuchi, etc. Les étoiles nous fascinent, mais les connaissons-nous vraiment ?

With all the passion, curiosity, and precise yet lyrical prose that have marked his previous books, Alan Lightman here explores the emotional and philosophical questions raised by discoveries in science, focusing most intently on the human condition and the needs of humankind. He looks at the difficult dialogue between science and religion, the conflict between our human desire for permanence and the impermanence of nature, the possibility that our universe is simply an accident, the manner in which modern technology has separated us from direct experience of the world, and our resistance to the view that our bodies and minds can be explained by scientific logic and laws.

Icy, rocky, sometimes dusty, always mysterious – comets and asteroids are among the Solar System's very oldest inhabitants, formed within a swirling cloud of gas and dust in the area of space that eventually hosted the Sun and its planets. Locked within each of these extra-terrestrial objects is the 4.6-billion-year wisdom of Solar System events, and by studying them at close quarters using spacecraft we can coerce them into revealing their closely-guarded secrets. This offers us the chance to answer some fundamental questions about our planet and its inhabitants.

When asked to explain Relativity simply, Albert Einstein himself once joked, “Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's Relativity.” But when most normal people without advanced training attempt to study the subject seriously, they’re quickly weighed down by the mathematics…

Humans have dreamed of travelling to the stars for as long as we knew that those points of light in the sky were stars like the Sun. Now, in the 21st century, there are actual studies and plans to send interstellar space probes to the nearest stars. Probably to Alpha Centauri which is only 4.3 light years away. Only! What is the history of plans to get to the nearest star? And what are the plans today to make these ideas a reality?

As command module pilot of Apollo 17, the last crewed flight to the moon, Ron Evans combined precision flying and painstaking geological observation with moments of delight and enthusiasm. As a patriotic American in charge of command module America, Evans was nicknamed “Captain America” by his fellow crew members.

Space exploration is as much a story of leadership and teamwork as it is a story of exploration and discovery. Leadership Moments from NASA delves into the organizational culture, leadership styles, and insights of NASA senior executives spanning five decades of human spaceflight, to share the lessons they learned from critical moments where they took on seemingly insurmountable challenges.

With the ongoing advancement of AI and other technologies, our world is becoming increasingly intelligent. From chatbots to innovations in brain-computer interfaces to the possibility of superintelligences leading to the Singularity later this century, our reality is being transformed before our eyes. This is commonly seen as the natural result of progress, but what if there's more to it than that? What if intelligence is an inevitability, an underlying property of the universe?

Nikola Tesla (1856 - 1943) was a genius who revolutionized the way the world looks at electricity. In February 1915, Tesla published a short 12-page work titled How Cosmic Forces Shape Our Destinies in the New York American magazine, recreated as an audiobook here. As Tesla explains in this work, "everything that exists, organic or inorganic, animated or inert, is susceptible to stimulus from the outside. There is no gap between, no break of continuity, no special and distinguishing vital agent. The same law governs all matter, all the universe is alive."

Described as the "ultimate engineer" during his career at NASA, George M. Low was a visionary architect and leader from the agency's inception in 1958 to his retirement in 1976. As chief of manned spaceflight at NASA, Low was instrumental in the Mercury, Gemini, and Apollo programs. Low's pioneering work paved the way for President Kennedy's decision to make a lunar landing NASA's primary goal in the 1960s.

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.

As technological advances and the creation of flying aircraft became realities, the sighting of UFOs increased, as did the interest in potential contact with aliens. It would hardly be groundbreaking for scientists in the 20th century to have a lunchtime discussion in which the search for extraterrestrial life arises, and the question of where it might reside is innocuous enough. However, a furor was created somewhat innocently when physicist Enrico Fermi voiced his “casual lunchtime remark” in the presence of colleagues in 1950.

Learn about the incomparable beauty of the Northern Lights with this accessible guide for aspiring astronomers and seasoned night sky observers. Tom Kerss covers the cultural and scientific context for auroras and offers a comprehensive guide to forecasting and photography so that listeners can fuse their own technical mastery with the infinite creativity of nature.

Mind Openers 2.0 is the second installment in a two-part set. It takes a fresh look at relativity, cosmology, and quantum theory by imagining a “sandbox universe”, in which space and time are treated as tangible and visualizable phenomena. In addition to providing an intuitive feel for the physics, the model makes a number of acutely unexpected predictions. The author is a geophysicist (MSc, fellow of geoscientists, Canada) and educator, who specializes in translating scientific material for the non-expert.

What price do we put on knowledge? How does it profit a man if he learns about the universe, but goes to bed hungry? When the economy takes a downturn, should we still go up into space? NASA missions aren’t cheap - sending astronauts into low Earth orbit or to the Moon, sending robotic spacecraft to explore the planets, and launching telescopes into space can cost millions or even billions of dollars. Lou Friedman, director of the Planetary Society, argues that even when the dollar is dear, the quest to explore our universe is priceless.

Americans are fascinated by the undeniable mystique of the elite world of Navy fighter pilots. In Bogeys and Bandits, Robert Gandt takes listeners on a thrilling ride in the FA-18 Hornet, one of the fastest, sleekest, and deadliest aircraft in the world. Gandt lived and worked with several pilots learning to fly the Hornet: the identical twins from Middle America; the computer nerd with a penchant for speed; the grandson of a Tuskegee Airman, trying to live up to a proud legacy; and two women dealing with the post-Tailhook world of the Navy.

The heart of this course examines the planets themselves, and reveals how they are constructed and how they differ from one another. By studying the physical astronomy of all the planets in the Solar System, we can attempt to understand their true nature. Ultimately, these lectures will bring us to a greater understanding of the Solar System's creation, which brings us again back to the beginning and what it means to us as we look outward from our rotating Earth.

Rope Hypothesis and Thread Theory is based on Bill Gaede's Rope Hypothesis. We apply the rope model to questions such as, what is gravity, light, electricity, and magnetism? What is thermodynamics? What is the difference between light and sound? What is plasma? How do batteries, antennas, and cathode ray tubes work? What is the difference between fundamental and composite objects? Does size scale make a difference when it comes to motion, friction, bending, stretching, and tension?
