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.

By 100 years ago, it seemed clear that the speed of light was the fastest possible speed. Causality was safe. And then quantum mechanics happened, introducing spooky connections that seemed to circumvent the law of cause and effect. From Aristotle's Physics to quantum teleportation, learn about the scientific pursuit of instantaneous connections in this insightful examination of our world.

In our rapidly evolving digital age, where reality often intertwines with the virtual, a question emerges: could our very existence be a part of a grander digital construct? "Simulation Theory for Beginners" dives headfirst into this profound question, exploring the enigmatic simulation hypothesis in depth.

How should a democracy choose its representatives? How does disease spread? How do computers teach themselves chess and why is chess easier for them than analysing a sentence? All of these are questions about geometry. Jordan Ellenberg reveals the mathematics behind some of the most important scientific, political and philosophical conundrums we face. The word 'geometry', from the Greek, means 'measuring the world'. If anything, geometry doesn't just measure the world - it explains it. Shape shows us how.

Block by Block offers an original perspective on thermodynamic science and history based on the three approaches of a practicing engineer, academician, and historian. The book synthesizes and gathers into one accessible volume a strategic range of foundational topics involving the atomic theory, energy, entropy, and the laws of thermodynamics.

Host Brett Moffatt and his guests will expand your knowledge and awareness of the latest research and developments as they happen. Unidentified aerial phenomena have swept the globe capturing the imaginations and attention of world powers, the military, scientists, and popular culture. Join us as we dissect the science facts from science fiction in this compelling offering into the world of UFOs/UAPs, in Australia and across the globe.

While scientists double down on the shocking figures, we still find ourselves unable to discuss climate change meaningfully among friends and neighbours - or even to grapple with it ourselves. The key to progress on climate change is in the psychology of human attitudes and our ability to change. Whether you're already alarmed and engaged with the issue, concerned but disengaged, a passive sceptic or an active denier, understanding our emotional reactions to climate change, is critical to coping on an individual level and convincing each other to act.

The Atomic Bomb podcast describes the history leading to the discovery of the atomic bomb, as well as its role in World War 2. We also examine the science behind the understanding of the atomic nucleus, how it enables the release of atomic energy, as well as the design and function of nuclear reactors and nuclear weapons. We follow the stories of some of the scientists involved – their discoveries, tragedies, and adventures. Lastly, we consider the geopolitical impact that nuclear weapons have made on the world.Credits and Licensing Information:Written, presented, and edited by Lane ...

Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: Observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria.

The periodic table is one of the most potent icons in science. It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the periodic table by van Spronsen (1969), has been out of print for a considerable time. The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and interested lay-persons alike.

This short, smart book tells you everything you need to know about "nothing". What remains when you take all the matter away? Can empty space - "nothing" - exist? To answer these questions, eminent scientist Frank Close takes us on a lively and accessible journey that ranges from ancient ideas and cultural superstitions to the frontiers of current research, illuminating the story of how scientists have explored the void and the rich discoveries they have made there.

In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes's formula has become a linchpin of the digital economy. But here's where things get interesting: Bayes's theorem can also be used to lay odds on the existence of extraterrestrial intelligence, and on the biggest question of all: how long will humanity survive?

The purpose of this audiobook was to explain something beautiful that doesn't exist yet. It explores time travel as precognitive dreaming, dematerialization with secret time machine technology and through consciousness travel, lucid dreaming, and remote viewing. It also examines various reports of time slips, dimensional doorways, claims of time travel, the physics of time travel, and the nature of timelessness and non-linear causality.

The audiobook is focused and high-yield, covering the most important topics you might expect to learn in a typical undergraduate organic chemistry course. The material is accurate, up-to-date, and broken down into bite-sized chapters. There are key takeaways following each chapter to drive home key points and quizzes to review commonly tested questions.

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.

Over the past few years, devastating tsunamis off the coast of the Indian Ocean have killed hundreds of thousands of people. Even more alarmingly, scientists predict that these tsunamis, as well as a series of earthquakes and volcanic eruptions, will be striking with even greater frequency and may eventually threaten Hawaii, California, and Oregon.

If you've ever found yourself fascinated by the idea of quantum computing but feel a little overwhelmed by the mind-blowing subject of quantum mechanics or concerned by climate change but haven't been able to get to grips with the details of global warming, this book is for you.

My beginner's book is your ticket to one of the coolest and most mysterious subjects out there. This isn't your average physics book. It's a portal to understanding the stuff that makes up... well, everything! Subatomic particles. Do not let their size fool you; they have a massive impact on the world around you—the fundamental part of how everything works and not as complex as you might fear.

Each episode, your AI particle physicists Bob and Alice break down the latest, most significant papers from the LHC experiments at CERN. From new measurements of the Higgs boson to the ongoing search for physics beyond the Standard Model, this podcast offers a clear, expert review of cutting-edge research's data, methods, and implications. Perfect for physics students, researchers, and anyone who wants to understand the universe at its most fundamental level.

Many people are fed up with the way traditional religion alienates them. Too easily it perpetuates conflict, vilifies science, and undermines reason. Nancy Abrams - a philosopher of science, lawyer, and lifelong atheist - is among these people, but she has also found freedom in imagining a higher power. Here, Abrams explores a radically new way of thinking about God. She shows why an omniscient, omnipotent God that created the universe and plans what happens is incompatible with science - but that this doesn’t preclude a God that can comfort and empower us.
