In 1919, British scientists led extraordinary expeditions to Brazil and Africa to test Albert Einstein's revolutionary new theory of general relativity in what became the century's most celebrated scientific experiment. The result ushered in a new era and made Einstein a global celebrity by confirming his dramatic prediction that the path of light rays would be bent by gravity. Today, Einstein's theory is scientific fact. Yet the effort to "weigh light" by measuring the gravitational deflection of starlight during the May 29, 1919, solar eclipse has been clouded by myth and skepticism.

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.

Why is red meat red? How do they decaffeinate coffee? Do you wish you understood the science of food but don't want to plow through dry, technical books? In What Einstein Told His Cook, University of Pittsburgh chemistry professor emeritus and award-winning Washington Post food columnist Robert L. Wolke provides reliable and witty explanations for your most burning food questions, while debunking misconceptions and helping you interpret confusing advertising and labeling.

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

L'essentiel à connaître sur la physique quantique ! Beaucoup d'entre nous ignorent à quoi la physique quantique renvoie précisément : d'où vient le terme " quantique " ? Quand cette science a-t‑elle vu le jour ? Pourquoi doit-on la distinguer de la physique classique ? En 50 notions, Blandine Pluchet vous emmène à travers un fascinant voyage au coeur de l'infiniment petit. Grâce aux découvertes de physiciens du xxe siècle tels que Planck, Einstein ou encore Bohr, quanta, photons, électrons et autres composants de la matière n'auront bientôt plus de secrets pour vous !

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.

This Basic Physics for Beginners is the ultimate guidebook you’ll ever need to learn the basics of Physics! This comprehensive yet easy-to-follow book on the principles of Physics will make you master the subject the easiest way!

The ABC of Relativity is still considered today, nearly 90 years after its first appearance, as an authoritative and accessible introduction to Einstein's Theory of Relativity. While there's nothing particularly easy about understanding the Theory of Relativity, many have found that Russell's explanation is easier to understand than Einstein's own writings on the topic. Russell covers topics such as time dilation and curved space-time, using non-scientific examples of train travel and aerial views of the terrain.

You may well be familiar with the fact that lightning, contrary to the popular saying, often strikes the same place twice. But this is just the tip of the iceberg when it comes to what many of us wrongly believe about the way the world works. Whether it's word of mouth, myths you've read about online or misremembered facts from school, we're bombarded by misconceptions about the science we come into contact with every day—this book will uncover the most popular myths to help you avoid contributing to the perpetuation of these misunderstandings.

Now in its fourth edition, this low-cost astronomy audio-textbook is designed for a one-semester introductory astronomy course aimed at non-science majors and future teachers. This new edition brings the latest astronomical discoveries together with cutting-edge teaching and learning strategies designed specifically to improve student learning and retention.

What is time? What does it mean for time to pass? Is it possible to travel in time? What is the difference between the past and future? Until the work of Newton, these questions were purely topics of philosophical speculation. Since then we've learned a great deal about time, and its study has moved from a subject of philosophical reflection to instead became part of the subject matter of physics.

Physics informs our understanding of how the world works - but more than that, key breakthroughs in physics have transformed everyday life. We journey back to 10 separate days in history to understand how particular breakthroughs were achieved, meet the individuals responsible and see how each breakthrough has influenced our lives.

Genetic engineering expert Dr Alina Chan and renowned science writer Matt Ridley examine the origins of SARS-CoV-2, the virus responsible for COVID-19, using their formidable skills to scrutinise arguments and rigorously analyse the sprawling data. Viral is a fascinating account that takes in pangolins, horseshoe bats, internet sleuths and misleading scientific papers. It details the evidence and investigates hypotheses for the virus origin, chief among them a potential laboratory leak or a natural spillover.

In der Schule war Physik vielleicht ein Unterrichtsfach, das nicht immer auf Beliebtheit gestoßen ist. Es schien oft langweilig und theoretisch und wenn Experimente durchgeführt wurden, waren diese häufig nicht sehr spannend. Man musste oft viele Gegenstände messen, wiegen oder beobachten und die Ergebnisse detailliert notieren. Formeln und Berechnungen waren quasi an der Tagesordnung und hatten durch ihre Komplexität eher eine abschreckende Wirkung. Allerdings ist Physik doch so viel mehr als blanke Theorie.

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

Einstein's theory of gravity, as beautiful as it is, seems to be in direct contradiction with another theory he helped create: quantum mechanics. From the explosions of neutron stars and the collisions of black holes to the modern scientific process as a means to seek truth and understanding in the cosmos, this audiobook takes the listener on a journey of learning and discovery that has been 100 years in the making.

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.

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.

Astrobiology is an exciting new subject, and one, arguably, more interdisciplinary than any other. Astrobiologists seek to understand the origin and evolution of life on Earth in order to illuminate and guide the search for life on other planets. In this Very Short Introduction, David C. Catling introduces the subject through our understanding of the factors that allowed life to arise and persist on our own planet, and for the signs we are looking for in the search for extraterrestrial life.
