Scientists in the past few decades have made crucial discoveries about how our cosmos evolved over the past 13.8 billion years. But there remains a critical gap in our knowledge: We still know very little about what happened in the first seconds after the Big Bang. At the Edge of Time focuses on what we have recently learned and are still striving to understand about this most essential and mysterious period of time at the beginning of cosmic history.

In Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the rivalries, epiphanies, and intrigues he witnessed firsthand.

Time rules our lives, woven into the very fabric of the universe-from the rising and setting of the sun to the cycles of nature, the thought processes in our brains, and the biorhythms in our day. Nothing so pervades our existence and yet is so difficult to explain. But now, in a series of 24 riveting lectures, you can grasp exactly why - as you take a mind-expanding journey through the past, present, and future, guided by a noted author and scientist.

The universe often presents us with the most unexpected yet profound gifts. On today's episode, we welcome Tero Isokauppila, a Finnish visionary and 13th-generation farmer with an extraordinary passion for mushrooms. As Tero often jests, "Mushrooms chose me, I didn't choose mushrooms," and it's this serendipitous journey that has transformed him into a leading advocate for the myriad benefits fungi offer.Growing up in Finland on a farm steeped in agricultural heritage, Tero Isokauppila was no stranger to the natural world. His father, an agronomist, and his mother, a physiology and anatomy ...

The human brain does a pretty amazing job of taking in a huge amount of data from multiple sensory modalities -- vision, hearing, smell, etc. -- and constructing a coherent picture of the world, constantly being updated in real time. (Although perhaps in discrete moments, rather than continuously, as we learn in this podcast...) We're a long way from completely understanding how that works, but amazing progress has been made in identifying specific parts of the brain with specific functions in this process. Today we talk to leading neuroscientist Doris Tsao about the specific workings of ...

Was ist der kosmische Mikrowellenhintergrund und was macht ihn so interessant?

Whether you are a scientist or a poet, pro-nuclear energy or staunch opponent, conspiracy theorist or pragmatist, James Mahaffey's books have served to open up the world of nuclear science like never before. With clear explanations of some of the most complex scientific endeavors in history, Mahaffey's new book looks back at the atom's wild, secretive past and then toward its potentially bright future.

Time moves forward, not backward---everyone knows you can't unscramble an egg. In the hands of one of today's hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself---a period of modern cosmology of which Einstein never dreamed.

Apollo is the behind-the-scenes story of an epic achievement. Based on exhaustive research that included many exclusive interviews, Apollo tells how America went from a standing start to a landing on the moon at a speed that now seems impossible. It describes the unprecedented engineering challenges that had to be overcome to create the mammoth Saturn V and the facilities to launch it. It takes you into the tragedy of the fire on Apollo 1, the first descent to the lunar surface, and the rescue of Apollo 13.

Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is ascientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely.

In this podcast, Taylor and Andrew investigate the past, present, and future of materials science and engineering. Topic areas ranging from cutting edge materials technology, the history of different materials, the commercialization of new materials, and exciting advances in processing and characterization are all covered in detail. Our episodes include things like the unlikely discovery of superglue or teflon, the fascinating backstories about modern biomaterials like dialysis filters, and updates on new technologies including wearable electronics, next generation batteries, and nanomaterials...

As smartphones, supercomputers, supercolliders, and AI propel us into an ever more unfamiliar future, How to Speak Science takes us on a rollicking historical tour of the greatest discoveries and ideas that make today's cutting-edge technologies possible. Wanting everyone to be able to "speak" science, YouTube science guru Bruce Benamran explains - as accessibly and wittily as in his acclaimed videos - the fundamental ideas of the physical world: matter, life, the solar system, light, electromagnetism, thermodynamics, special and general relativity, and much more.

The Trouble with Physics argues that a limited notion of time is holding physics back. It's time for a major revolution in scientific thought. The reality of time could be the key to the next big breakthrough in theoretical physics. What if the laws of physics themselves were not timeless? What if they could evolve? Time Reborn offers a radical new approach to cosmology that embraces the reality of time and opens up a whole new universe of possibilities.

Most of us have heard of black holes and supernovas, galaxies and the big bang. But few of us understand more than the bare facts about the universe we call home. What is really out there? How did it all begin? Jo Dunkley begins in Earth's neighborhood, explaining the nature of the solar system, the stars in our night sky, and the Milky Way. She then moves out past nearby galaxies - and back in time - to the horizon of the observable universe, which contains over a hundred billion galaxies, each with billions of stars, many orbited by planets, some of which may host life.

For fans of The Astronaut Wives Club, The Mercury 13 reveals the little-known true story of the remarkable women who trained for NASA space flight. In 1961, just as NASA launched its first man into space, a group of women underwent secret testing in the hopes of becoming America’s first female astronauts. They passed the same battery of tests at the legendary Lovelace Foundation as did the Mercury 7 astronauts, but they were summarily dismissed by the boys’ club at NASA and on Capitol Hill.

How big is the universe? How many numbers are there? And is infinity + 1 is the same as 1 + infinity? Such questions occur to young children and our greatest minds. And they are all the same question: What is infinity? In Beyond Infinity, Eugenia Cheng takes us on a staggering journey from elemental math to its loftiest abstractions. Along the way, she considers how to use a chessboard to plan a worldwide dinner party, how to make a chicken-sandwich sandwich, and how to create infinite cookies from a finite ball of dough.
