The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

We all know that without water we couldn't survive, and that sometimes a cup of coffee or a glass of wine feels just as vital. But do we really understand how much we rely on liquids, or the destructive power they hold? Set over the course of a flight from London to San Francisco, Liquid Rules offers listeners a fascinating tour of these formless substances, told through the language of molecules, droplets, heartbeats, and ocean waves.

Bringing together the best and most interesting science stories appearing in Quanta Magazine over the past five years, Alice and Bob Meet the Wall of Fire reports on some of the greatest scientific minds as they test the limits of human knowledge. It communicates science by taking it seriously, wrestling with difficult concepts, and clearly explaining them in a way that speaks to our innate curiosity about our world and ourselves.

This is the story of a quest: to find a Theory of Everything. Einstein dedicated his life to seeking this elusive Holy Grail, a single, revolutionary 'god equation' which would tie all the forces in the universe together, yet never found it. Some of the greatest minds in physics took up the search, from Stephen Hawking to Brian Greene. None have yet succeeded. In The God Equation, renowned theoretical physicist Michio Kaku takes the listener on a mind-bending ride through the twists and turns of this epic journey: a mystery that has fascinated him for most of his life.

Would you like to know how the universe works? Scientists have been asking that question for a long time and have found that many of the answers can be found in the study of particle physics, the field that focuses on those impossibly tiny particles with unbelievably strange names - the hadrons and leptons, baryons and mesons, muons and gluons - so mystifying to the rest of us.

The United States, Russia, China, and other countries around the world have experienced contact with the phenomenon, as we will discover in War. Americans demand that their leaders reveal what they know. They demand disclosure. But what do our allies, and our enemies, know about the phenomenon and why have they not already disclosed? Why is this an international issue, and not just an American one? And what does that tell us about the phenomenon?

Time One tackles mankind's most baffling question: How did the world begin? After challenging old thinking about forty-seven crucial scientific problems, Time One author Colin Gillespie solves forty-five of them and comes up with a strikingly simple answer to the most perplexing question of them all: How did the world begin?

Time One takes an iconoclastic look at contemporary physics, notably relativity, quantum mechanics and string theory.

In the summer of 1964, a reclusive young professor at the University of Edinburgh wrote two scientific papers which have come to change our understanding of the most fundamental building blocks of matter and the nature of the universe. Peter Higgs posited the existence an almost infinitely tiny particle—today known as the Higgs boson—which is the key to understanding why particles have mass, and but for which atoms and molecules could not exist.

Inspired by Albert Einstein's theory of relativity and Bertrand Russell and David Hilbert's pursuit of the fundamental rules of mathematics, some of the most brilliant minds of the generation came together in post-World War I Vienna to present the latest theories in mathematics, science, and philosophy and to build a strong foundation for scientific investigation. Composed of such luminaries as Kurt Gödel and Rudolf Carnap, and stimulated by the works of Ludwig Wittgenstein and Karl Popper, the Vienna Circle left an indelible mark on science.

This is a landmark in science writing. It resurrects from the vaults of neglect the polymath Jerome Cardano, a Milanese of the 16th century. Who is he? A gambler and blasphemer, inventor and chancer, plagued by demons and anxieties, astrologer to kings, emperors and popes. This stubborn and unworldly man was the son of a lawyer and a brothel keeper but also a gifted physician and the unacknowledged discoverer of the mathematical foundations of quantum physics.

The night sky is an endless source of wonder and mystery. For thousands of years it has been at the heart of scientific and philosophical inquiry, from the first star catalogues etched into ancient Mesopotamian clay tablets to the metres-wide telescopes constructed in Chile's Atacama Desert today. On a clear night it is hard not to look up and pick out familiar constellations, and to think of the visionary minds who pioneered our understanding of what lies beyond.

Goswami's basic premise is that quantum physics is not only the future of science, but is also the key to understanding consciousness, life, death, God, psychology, and the meaning of life. Quantum physics is an antidote to the moral sterility and mechanistic approach of scientific materialism and is the best and clearest approach to understanding our universe. In short, quantum physics is indeed the theory of everything.

E=mc2: It may be Einstein’s most well-known contribution to modern science, but how many people understand the thought process or physics behind this famous equation? In this collection of his seven most important essays on physics, Einstein guides the listener step-by-step through the many layers of scientific theory that formed a starting point for his discoveries.

The brain is made up of 85 billion neurons, which are connected by over 100 trillion synapses. For over a century, a diverse array of researchers have been trying to find a language that can be used to capture the essence of what these neurons do and how they communicate - and how those communications create thoughts, perceptions, and actions. The language they were looking for was mathematics, and we would not be able to understand the brain as we do today without it.

Scientists Daniel and Kelly cannot stop talking about our amazing, wonderful, weird Universe! Each episode is a fun, easy-to-understand, and in-depth explanation of topics in science, from particles to black holes to moon colonies to ecosystems to parasites and everything else in the Universe!

We are constantly bombarded with inaccurate, contradictory and sometimes misleading information - until now. Ben Goldacre masterfully dismantles the dubious science behind some of the great drug trials, court cases and missed opportunities of our time. He also shows us the fascinating story of how we know what we know, and gives us the tools to uncover bad science for ourselves.

Brian Cox and Robin Ince present a witty, irreverent look at the world according to science. The Infinite Monkey Cage has become one of BBC Radio 4’s most popular science-based programmes. In each episode, physicist Brian Cox and comedian Robin Ince delve into a particular field of science, with the help of guests from the worlds of science, academia and entertainment. These 25 episodes feature subjects ranging from music to Frankenstein, from particle physics to the science of sleep, and from astronauts to insects. Also included are the 2016 and 2017 Christmas Special episodes.

There are approximately 25,000 "city killer" asteroids in near-Earth orbit—and most are yet to be found. Small enough to evade detection, they are capable of large-scale destruction, and represent our greatest cosmic threat. But in September 2022, against all odds, NASA's Double Asteroid Redirection Test (DART) mission deliberately crashed a spacecraft into a carefully selected city killer, altering the asteroid's orbit. In How to Kill an Asteroid, award-winning science journalist Robin George Andrews reveals the development of the technology that made it possible

Did you know that there’s so much empty space inside matter that the entire human race could be squeezed into the volume of a sugar cube? Or that you grow old more quickly on the top floor of a building than on the ground floor? The two towering achievements of modern physics are quantum theory and Einstein’s general theory of relativity. But, almost a century after their advent, most people haven’t the slightest clue what either is about. Get set for the most entertaining science book of the year.

For decades after the structure of DNA was identified, scientists focused purely on genes, the regions of the genome that contain codes for the production of proteins. Other regions - 98 percent of the human genome - were dismissed as ‘junk’. But in recent years researchers have discovered that variations in this ‘junk’ DNA underlie many previously intractable diseases, and they can now generate new approaches to tackling them.
