Why does the universe have mass at all? Why are stars, galaxies, and even people possible instead of a cosmos of pure light? The discovery of the Higgs boson at CERN in 2012 gave science a long-awaited answer—but not the final one. This book explores the Higgs boson not only as a particle of physics but as a symbol of humanity’s restless search for meaning. From the pioneering ideas of six physicists in 1964 to the monumental experiments of the Large Hadron Collider, he guides the listener through the science with clarity and wit, showing how invisible fields shape the visible world.

A quest for understanding reality using two vastly different methods of inquiry.

Look up at the night sky. Every star, every distant world, and the very iron in your blood are remnants of an ancient cosmic story written 4.5 billion years ago. Welcome to Solar System Odyssey—a narrative voyage through our local celestial neighborhood.The Story Our solar system did not begin in serene quiet; it emerged from violent chaos. 4.5 billion years ago, a massive interstellar cloud of gas and dust collapsed under its own gravity to form the solar nebula.The Protoplanetary Disk: As the cloud collapsed, conservation of angular momentum caused it to spin faster and flatten into a ...

A microscopic worm has 959 cells. The Milky Way galaxy contains roughly the same number of stellar nursery cavities. The two are separated by twenty-four orders of magnitude in size—yet their proportions match almost exactly. This is not the only such pair. From protons to stars, from bacteria to galactic structures, from cities to the cosmic web, the same organizational pattern keeps repeating across forty-two orders of magnitude. A 200,000-trial statistical test of seven such pairings returned p = 0.000055—odds of about 1 in 18,000.

We do not see reality as it is. We see reality as we are. Imagine standing on a cliff overlooking the ocean. The wind on your face, the roar of the surf, and the deep blue of the water feel immediate, tangible, and unquestionably real. But how much of that experience belongs to the world itself, and how much belongs entirely to your brain? The physical universe exists independently of us, but our biological access to it is permanently indirect. The human mind does not present raw reality; it builds a highly customized model.

Astrophysicist Lucie Green takes us on a brilliant tour of the most important cosmic maps in human history—visualizations of the cosmos that show us what we’ve discovered, and what we could know, about the universe and its invisible wonders. We think of space as merely the empty distance...

Cosmos is one of the bestselling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

Fans of xkcd ask Munroe a lot of strange questions: What if you tried to hit a baseball pitched at ninety percent the speed of light? How fast can you hit a speed bump while driving and live? If there was a robot apocalypse, how long would humanity last? What if everyone only had one soulmate? What would happen if the moon went away? In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators.

Gene Kranz was present at the creation of America's manned space program and was a key player in it for three decades. As a flight director in NASA's Mission Control, Kranz witnessed firsthand the making of history. He participated in the space program from the early days of the Mercury program to the last Apollo mission, and beyond. He endured the disastrous first years when rockets blew up and the United States seemed to fall further behind the Soviet Union in the space race.

As Carl Sagan did for astronomy and Brian Green did for cosmology, Walter Lewin takes listeners on a marvelous journey in For the Love of Physics, opening our eyes as never before to the amazing beauty and power with which physics can reveal the hidden workings of the world all around us. "I introduce people to their own world," writes Lewin, "the world they live in and are familiar with but don't approach like a physicist - yet."

J. Robert Oppenheimer was one of the iconic figures of the 20th century, a brilliant physicist who led the effort to build the atomic bomb but later confronted the moral consequences of scientific progress. When he proposed international controls over atomic materials, opposed the development of the hydrogen bomb, and criticized plans for a nuclear war, his ideas were anathema to powerful advocates of a massive nuclear buildup during the anti-Communist hysteria of the early 1950s.

Classical physics is about how things move, why they move, and how they work. It's about making sense of motion, gravity, light, heat, sound, electricity, and magnetism, and seeing how these phenomena interweave to create the rich tapestry of everyday experience. It is, in short, the hidden order of the universe.

The Pleasure of Finding Things Out is a magnificent treasury of the best short works of Richard P. Feynman, from interviews and speeches to lectures and printed articles. A sweeping, wide-ranging collection, it presents an intimate and fascinating view of a life in science - a life like no other. From his ruminations on science in our culture to his Nobel Prize acceptance speech, this book will delight anyone interested in the world of ideas.

From space exploration and quantum optics, to biomedical imaging and defense, today’s top scientific minds are using lasers, spectroscopy, sensors, and optics to deliver cutting-edge innovation to our society. In intimate conversations with those pushing the boundaries of human knowledge, “All Things Photonics” spotlights photonics industry progress from beyond the lab. Hear how 3D printed microscopes — and those developed for a fraction of the cost — offer our best hope for diagnosing disease in the developing world; why spectroscopy might be the most valuable tool in the crime ...

What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There's no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson. But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in digestible chapters consumable anytime and anywhere in your busy day.

If you move at high speed, time slows down, space squashes up, and you get heavier. Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing - and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity. 

Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics.
