Asked to name a great physicist, most people would mention Newton or Einstein, Feynman or Hawking. But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list. Maxwell, an unassuming Victorian Scotsman, explained how we perceive color. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.

In Reconnecting to the Source he unpacks the science behind spiritual experience, investigating the ways in which we can access realms of experience beyond the everyday. It is in these moments, when our conscious minds are in contact or perhaps even overridden by our unconscious selves, that we can explore the depths of spiritual meaning. In addition to a foreword by Deepak Chopra, the book includes new, never before published contributions from a long list of well-known writers and public figures.

Carl Sagan, writer and scientist, returns from the frontier to tell us about how the world works. In his delightfully down-to-earth style, he explores and explains a mind-boggling future of intelligent robots, extraterrestrial life and its consequences, and other provocative, fascinating quandaries of the future that we want to see today.

Behind the familiar surfaces of the telephone, radio, and television lies a sophisticated and intriguing body of knowledge known as information theory. This is the theory that has permitted the rapid development of all sorts of communication, from color television to the clear transmission of photographs from the vicinity of Jupiter. Even more revolutionary progress is expected in the future.

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.

These stories from Quanta Magazine map the routes of mathematical exploration, showing listeners how cutting-edge research is done, while illuminating the productive tension between conjecture and proof, theory and intuition. Listeners of The Prime Number Conspiracy are headed on "breathtaking intellectual journeys to the bleeding edge of discovery strapped to the narrative rocket of humanity's never-ending pursuit of knowledge," says Quanta editor-in-chief Thomas Lin.

In Neil deGrasse Tyson’s delightful journey through the cosmos, his fictional character Merlin responds to popular questions asked by adults and children alike. Merlin, a timeless visitor from Planet Omniscia in the Andromeda Galaxy, has observed firsthand many of the major scientific events of Earth’s history.

"The Universal One" by Walter Russell is an ambitious and comprehensive work that endeavors to blend the realms of science, philosophy, and spirituality into a singular, cohesive theory of the universe.

This Very Short Introduction presents the field of fluid mechanics by focusing on the underlying physical ideas and using everyday phenomena to demonstrate them, from dripping taps to swimming ducks. Eric Lauga shows how this set of fundamental physical concepts can be applied to a wide range of flow behaviors and highlights the role of fluid motion in both the natural and industrial worlds. This book also considers future applications of fluid mechanics in science.

Right now, you are orbiting a black hole. The Earth goes around the Sun, and the Sun goes around the centre of the Milky Way: a supermassive black hole—the strangest and most misunderstood phenomenon in the galaxy. In A Brief History of Black Holes, University of Oxford astrophysicist Dr Becky Smethurst charts the scientific breakthroughs that have uncovered the weird and wonderful world of black holes, from Hawking radiation to the iconic first photographs of a black hole in 2019.

When asked to explain Relativity simply, Albert Einstein himself once joked, “Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's Relativity.” But when most normal people without advanced training attempt to study the subject seriously, they’re quickly weighed down by the mathematics…

In a field known for startling ideas, the Many-Worlds Interpretation (MWI) of quantum mechanics may take the prize. It holds that parallel to our own world are a large number of other universes, almost identical to ours but with small variations. Copies of each of us inhabit a myriad of these worlds. But they are not us exactly; they share our past history, but they are different people who have unique futures. Although these realms are invisible and can’t communicate with each other, prominent physicists are convinced they must exist.

Are we living in a simulation? MIT computer scientist Rizwan Virk draws from research and concepts from computer science, artificial intelligence, video games, quantum physics, and ancient mystics to explain why we may be living inside a simulated reality like the Matrix. The Simulation Hypothesis is the definitive book on simulation theory and is now completely updated to reflect the latest developments in artificial intelligence and virtual reality.

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.

In June 1925, 23-year-old Werner Heisenberg, suffering from hay fever, retreated to a small, treeless island in the North Sea called Helgoland. It was there that he came up with one of the most transformative scientific concepts: quantum theory. Almost a century later, quantum physics has given us many startling ideas: ghost waves, distant objects that seem magically connected to each other, cats that are both dead and alive. Today our understanding of the world around us is based on this theory. And yet it is still profoundly mysterious.

Peter has motor neurone disease, a condition universally considered by doctors to be terminal. It will destroy his nerve cells, and he is told that within an average of two years, it will take his life, too. But, face to face with death, he decides there is another way. Using his background in science and technology, he navigates a new path, one that will enable him not just to survive but to thrive.

In January 2020, as people started dying from a new virus in Wuhan, China, few really understood the magnitude of what was happening. Except, that is, a small group of scientific misfits who in their different ways had been obsessed all their lives with how viruses spread and replicated - and with why the governments and the institutions that were supposed to look after us, kept making the same mistakes time and again. This group saw what nobody else did. A pandemic was coming. We weren't prepared.

This is a conceptual overview of Einstein's relativity. The book exists in two versions. This edition does not include mathematics or algebra, while the other version does.

منذ بزوغ فجرها، ضُربت على البشرية قيود العُزلة والوحدة في كونٍ شاسع ومُظلم وعصي على التخيُّل.. ولأن الإنسان يحمل رغبة متأصِّلة تدفعه دائمًا إلى السعي وراء المجهول، فلطالما حاول رصد واستكشاف الفضاء، وأطلق مراصده نَهِمة تُفتِّش السماء رقعةً رقعةً، أملًا في العثور على أدنى إشارة تَعِد بوجود أيِّ شكل آخر من أشكال الحياة الذكية غيره في الكون

We take time for granted as it passes during every moment of our existence. Other things may change, but time remains constant and predictable. The past, the present, and the future exist within a harmonious, reliable, and never-changing system. Or at least that’s how it seems… It was Albert Einstein who, in 1905, first theorized that time might not be quite as straightforward as that.
