Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can't affect the other. Quantum entanglement rejects this assumption, offering impeccable reasoning and irrefutable evidence of the opposite. Is quantum entanglement mystical, or just mystifying?

This 10-part history of mathematics reveals the personalities behind the calculations: the passions and rivalries of mathematicians struggling to get their ideas heard. Professor Marcus du Sautoy shows how these masters of abstraction find a role in the real world and proves that mathematics is the driving force behind modern science.  

In his compelling new book, Dr Arthur Turrell makes the case for cutting-edge new techniques in nuclear energy—innovations that would allow us to recreate the power of the stars on our own planet. Filled with the remarkable stories of the scientists and entrepreneurs who have dedicated their lives to a seemingly impossible dream, The Star Builders is an unmissable insight into the future of life—and space—on our planet.

Space is the biggest, oldest, hottest, coldest, strangest thing a human can study. It's no surprise then, that the weirdest facts in science (not to mention the weirdest scientists themselves) are found in astrophysics and cosmology. If you're looking for instructions on how to set up your grandad's telescope this book probably isn't for you. In Astronomical, Tim James takes us on a tour of the known (and unknown) Universe, focusing on the most-mind boggling stuff we've come across, as well as unpacking the latest theories about what's really going on out there.

We all know that we depend on elements for survival - from oxygen in the air we breathe to carbon in the molecular structures of all living things. But we seldom appreciate how, say, phosphorus holds our DNA together or how potassium powers our optic nerves enabling us to see.

A breakout best seller in Italy, now available for American listeners for the first time, Genesis: The Story of How Everything Began is a short, humanistic tour of the origins of the universe, earth, and life - drawing on the latest discoveries in physics to explain the seven most significant moments in the creation of the cosmos.

So you’ve fallen in love with space and now you want to see it for yourself, huh? You want to witness the birth of a star, or visit the black hole at the center of our galaxy? You want to know if there are aliens out there, or how to travel through a wormhole? You want the wonders of the universe revealed before your very eyes? Well stop, because all that will probably kill you.

Did NASA really spend millions creating a pen that would write in space? Is chocolate poisonous to dogs? Does stress cause gray hair? These questions are a sample of the urban lore investigated in this audiobook, Fact or Fiction: Science Tackles 58 Popular Myths. Drawing from Scientific American’s “Fact or Fiction” and “Strange But True” columns, we’ve selected 58 of the most surprising, fascinating, useful, and just plain wacky topics confronted by our writers over the years.

Is time an illusion? Is time travel possible? Could time end? In this audiobook, A Question of Time, we take an interdisciplinary look at the fourth dimension, exploring the latest thinking on the nature of time and the ways it dominates our physical and mental worlds. 

For going on two decades, Scientific American’s “Ask the Experts” column has been answering reader questions on all fields of science. We’ve taken your questions from the basic to the esoteric and reached out to top scientists, professors, and researchers to find out why the sky is blue or whether we really only use 10 percent of our brains. Now, we’ve combed through our archives and have compiled some of the most interesting questions (and answers) into a series of books. 

Science fiction has imagined some pretty wild ideas about how the universe could work - from hidden extra dimensions in Interstellar to life as a mental projection in The Matrix. But these imaginings seem downright tame compared to the mind-bending science now coming out of physics and astronomy, and in this audiobook, we look at the strange and fascinating discoveries shaping (and reshaping) the field today. 

The fundamental outlines of the physical world, from its tiniest particles to massive galaxy clusters, have been apparent for decades. Does this mean physicists are about to tie it all up into a neat package? Not at all. Just when you think you’re figuring it out, the universe begins to look its strangest, and this book illustrates how answers often lead to more questions and open up new paths to insight. 

Our nearest planetary neighbor has been the subject of endless fascination and wide-ranging theories throughout history. Is there life on Mars? Was there ever life on Mars? What was the atmosphere like thousands or millions of years ago? From Percival Lowell, who built his own observatory so he could dedicate himself to studying the red planet, to NASA landing the car-sized Curiosity rover in 2012, this book traces Scientific American's coverage of the observation and exploration of Mars. 

As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realisation that the dinosaurs had been wiped out by just such an impact. Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects and plans for high-tech hardware that could deflect an incoming object from a collision course - a procedure depicted in several Hollywood movies.

Following 10 years of detailed investigation, documentary film-maker Guillaume Coudray presents a powerful examination of the use of nitro-additives in meat. As he reveals, most mass-produced processed meats, and now even many ‘artisanal’ products, contain chemicals that react with meat to form cancer-causing compounds. He tells the full story of how, since the 1970s, the meat-processing industry has denied the health risks because these additives make curing cheaper and quicker, extending shelf life and giving meat a pleasing pink colour.

Blood carries life, yet the sight of it makes people faint. It is a life-saver, and can transmit deadly infections. It is medicine, and a commodity dearer than oil. Each of us has nine to 12 pints of it, yet many don’t know their own blood type. For all its ubiqutousness, menstruation is perhaps the single most demonized biological event. In Nine Pints, Rose George takes us from ancient practices of bloodletting to a cutting-edge trauma ward. 

A powerful reflection on life in isolation, in pursuit of the dream of Mars. In 2013 Kate Greene moved to Mars. On NASA’s first HI-SEAS simulated Mars mission in Hawaii, she lived for four months in an isolated geodesic dome with her crewmates, gaining incredible insight into human behaviour in tight quarters, as well as the nature of boredom, dreams and isolation that arise amidst the promise of scientific progress and glory. 

From the secret fossils of London to the three-billion-year-old rocks of the Scottish Highlands, and from state-of-the-art Californian laboratories to one of the world's most dangerous volcanic complexes hidden beneath the green hills of western Naples, set out on an adventure to those parts of the world where the Earth's life-story is written into the landscape. Helen Gordon turns a novelist's eye on the extraordinary scientists who are piecing together this planetary drama.

Written by experts and offering listeners the opportunity to pass off appropriated knowledge as their own, the Bluffer's Guides provide hard fact masquerading as frivolous observation in one witty, easy listen. Instantly acquire all the knowledge you need to pass as an expert in the world of quantum physics. Never again confuse a boson with a hadron, a fermion with a meson, or a photon with a lepton or an electron. If in doubt, always fall back on a bluffon.

From atomic structures to theories about magnetic forces, scientific progress has given us a good grasp on the properties of many different materials. However, science cannot tell us how to measure the temperature of steel just by looking at it, or how to sculpt stone into all kinds of shapes, or what it feels like to blow up a balloon of glass. Handmade is the story of materials through making and doing. Author and material scientist Anna Ploszajski journeys into the domain of makers and craftspeople to comprehend how the most popular materials really work.
