What is matter? Matter is the stuff from which we and all the things in the world are made. Everything around us - from desks, to books, to our own bodies - are made of atoms, which are small enough that a million of them can fit across the breadth of a human hair. Inside every atom is a tiny nucleus and orbiting the nucleus is a cloud of electrons. The nucleus is made out of protons and neutrons, and by zooming in further, you would find that inside each there are even smaller particles: quarks.

The marvelous complexity of the universe emerges from several deep laws and a handful of fundamental constants that fix its shape, scale, and destiny. Where did these laws and these constants come from? And why are the laws so fruitful when written in the language of mathematics? Author Peter Atkins considers the minimum effort needed to equip the universe with its laws and its constants. He explores the origin of the conservation of energy, of electromagnetism, of classical and quantum mechanics, and of thermodynamics, showing how all these laws spring from deep symmetries.

How to Love the Universe is a new kind of science writing by an author truly enamored of the world around him. In 10 short chapters of lyrical prose - each one an ode to a breathtaking realm of discovery - Stefan Klein uses everyday objects and events as a springboard to meditate on the beauty of the underlying science.

In Signposts to God, particle physicist Peter Bussey introduces listeners to the mysteries of modern physics and astronomy. Authored in clear, accessible prose, Bussey provides a primer on topics such as the laws of nature, quantum physics, fine-tuning, and current cosmological models. Bussey argues that, far from ruling out a divine creator, modern physics and astronomy present us with compelling signposts to God. The more we know about the cosmos and our presence in it, the more plausible belief in God becomes.

The beauty of fractal patterns and their relation to chaos, as well as the history of chaos, and its uses in the real world and implications for the philosophy of science are all discussed in this Very Short Introduction audiobook.

Black holes are a constant source of fascination to many due to their mysterious nature. This Very Short Introduction audiobook addresses a variety of questions, including what a black hole actually is, how they are characterized and discovered, and what would happen if you came too close to one.

In How the Laser Happened, Nobel laureate Charles Townes provides a highly personal look at some of the leading events in 20th-century physics. This lively memoir, packed with firsthand accounts and historical anecdotes, is an invaluable resource for anyone interested in the history of science and an inspiring example for students considering scientific careers.

Sixty-six million years ago an asteroid as large as Mt. Everest hit what is now the Yucatan Peninsula at a speed ten times faster than the fastest rifle bullet. Debris from the impact blew into space, re-entered the atmosphere as a swarm of shooting stars that burned the global forests and grasslands, leaving behind a thin global layer containing rock from the asteroid and from Mexico, and smoke from the fires. This layer marks one of the greatest extinctions in Earth history including not just dinosaurs, but also fish, plankton, ammonites, and plants making up about 75% of the known species.

Atomic weaponry is widely understood as a story of American scientific achievement—but scientists working in Britain played a vital role in its development. Including Nobel Prize winners and Jewish refugees from Nazi Germany, these scientists have long since been forgotten. But without their expertise, Robert Oppenheimer's research at Los Alamos would never have succeeded. Gareth Williams unearths the true story of the top-secret British atomic program, codenamed "Tube Alloys," established in 1940.

Are the physical laws of our universe finely tuned, such that life can exist? What does this imply about how our universe formed? Questions like these are examined in Nature's Balancing Act, presented for a wide audience.

Following the discovery of the Higgs boson, Frank Close has produced this major revision to his classic and compelling introduction to the fundamental particles that make up the universe. Frank Close takes us on a journey into the atom to examine known particles such as quarks, electrons, and the ghostly neutrino, and explains the key role and significance of the Higgs boson. Along the way he provides fascinating insights into how discoveries in particle physics have actually been made, and discusses how our picture of the world has been radically revised in the light of these developments.

The Superluminal Universe reveals, for the first time in English, the incredible insights of French quantum physicist Professor Regis Dutheil. Thanks to the development of particle accelerators, physicists are now able to propel particles (tachyons) at a speed close to that of light (300,000 km per second). At these extreme speeds, the laws that govern our universe no longer apply. Professor Dutheil's work has shown that the theory of relativity is not incompatible with that of tachyons, provided that we allow for the possibility of a double reality.

This is a theoretical physicist's grand tour of how life emerged on Earth and, perhaps most importantly, how human civilization will begin expanding beyond our home planet. According to Dr. Adriana Marais, living on more than one planet is an inevitability of becoming a more advanced society, but the process of getting there will provide us with the essential tools for better stewardship of our own. Humanity has always looked up at the night sky and wondered what lies beyond our world.

What are we made up of? What holds material bodies together? Is there a difference between terrestrial matter and celestial matter? When Democritus stated that we are made up of atoms, few people believed him. Not until Galileo and Newton in the seventeenth century did people take the idea seriously, and it was another four hundred years before we could reconstruct the elementary components of matter.

David J. Helfand reconstructs the history of the universe—back to its first microsecond 13.8 billion years ago—with the help of atoms. He shows how, by using detectors and reactors, microscopes and telescopes, we can decode the tales these infinitesimal particles tell.

Earth stands at a tipping point. As we fail to curtail emissions fast enough, our planet stares down a cascade of imminent, catastrophic, and irreversible disaster triggered by climate change. Yet a potent technology already exists to buy us more time: solar geoengineering. Through methods such as atmospheric aerosols, human-generated cirrus clouds, and solar sails, we humans can—at least in the short term—slow the Earth's warming. Should we?
