光速c、重力定数G、電子の電荷の大きさe、プランク定数h。これらの基礎物理定数は日常から宇宙までを支配する法則が数値となったものだ。我々はふだん物理定数など意識せずに暮らしているが、この値が違えば太陽はブラック・ホールと化し、人類は地球にいられず火星に住むハメになり、宇宙の姿は激変する。

Nothing has had a more profound impact on the development of modern civilization than thermodynamics. Thermodynamic processes are at the heart of everything that involves heat, energy, and work, making an understanding of the subject indispensable for careers in engineering, physical science, biology, meteorology, and even nutrition and culinary arts. Get an in-depth tour of this vital and fascinating science in 24 enthralling lectures suitable for everyone from science novices to experts who wish to review elementary concepts and formulas.

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.

Science and technology are, without a doubt, two forces that will change the way you live your life in the coming months, years, and decades. And in recent decades, these forces have evolved and developed at a lightning-fast pace. Explore the many possibilities of what your future may look like with these 24 lectures: a scientifically accurate and enlightening survey of today's most advanced research in fields such as engineering, biology, chemistry, and theoretical physics.

L’immagine più bella che gli astronauti hanno colto dalla Luna è stata quella della Terra. Fulgida e azzurra nel buio più nero, delicata, come vivente. Qualcosa di unico nello Spazio sconfinato. Eppure noi umani siamo spesso inebriati dal sogno di lasciarla per trasferirci su altri pianeti. In principio fu la fantascienza: nel 1966, mentre il programma Apollo era in pieno svolgimento, negli USA andava in onda per la prima volta la serie tv Star Trek in cui la nave stellare Enterprise viaggiava alla ricerca di "strani, nuovi mondi".

By the end of World War I, Albert Einstein had become the face of the new science of theoretical physics and had made some powerful enemies. One of those enemies, Nobel Prize winner Philipp Lenard, spent a career trying to discredit him. Their story of conflict, pitting Germany's most widely celebrated Jew against the Nazi scientist who was to become Hitler's chief advisor on physics, had an impact far exceeding what the scientific community felt at the time.

Since the fall of the Soviet Union, long-suppressed information has emerged on Heisenberg’s role in the Nazi atomic bomb project. In Beyond Uncertainty, Cassidy interprets this and other previously unknown material within the context of his vast research and tackles the vexing questions of a scientist’s personal responsibility and guilt when serving an abhorrent military regime.

The Toy-Physics podcast gives a gentle overview of the book Toy-Physics: A Foundation for Faith, Hope and Renewal.  It leads to a rigorous and common-sense accessible alternative to the spacetime story of modern physics.  The Toy-Physics story pulls physicality, spirituality, and reality into a strong triangular bond of unity.

Introduzione alla relatività ristretta di Einstein

A show where we discuss a variety of topics related to the natural world, physics, metaphysics, mythology, and philosophy! We're an Ottawa based scientific paranormal investigation and research team. We use every resource possible to attempt to debunk and disprove paranormal claims, using scientific methodology and skepticism - in hopes we can't!

Es ist die berühmteste Theorie aller Zeiten. Aber wie viele von uns wissen, was sie genau bedeutet? Und warum ist sie hundert Jahre später immer noch relevant für uns? Der Hawking-Schüler und Bestsellerautor Christophe Galfard untersucht die wahre Bedeutung hinter der ikonischen Abfolge von Symbolen, aus denen Einsteins große Gleichung besteht. In seinem leicht zugänglichen und anschaulichen Stil schildert Christophe Galfard die Auswirkungen der bekanntesten Gleichung aller Zeiten auf unsere Vorstellung von der Realität und eröffnet uns ein neues Verständnis der Natur von Raum und Zeit.

In the 1990s, researchers in the Arctic noticed that floating summer sea ice had begun receding. This was accompanied by shifts in ocean circulation and unexpected changes in weather patterns throughout the world. The Arctic's perennially frozen ground, known as permafrost, was warming, and treeless tundra was being overtaken by shrubs. What was going on? Brave New Arctic is Mark Serreze's riveting firsthand account of how scientists from around the globe came together to find answers.

Oxford mathematician and author John Lennox takes a closer look at Hawking's logic regarding what brought the universe into being. In lively, layman's terms, Lennox guides us through the key points in Hawking's arguments - with clear explanations of the latest scientific and philosophical methods and theories - and demonstrates that far from disproving a creator God, they make his existence seem all the more probable.

Can there be freedom and free will in a deterministic world? Renowned philosopher Daniel Dennett emphatically answers "yes!" Using an array of provocative formulations, Dennett sets out to show how we alone among the animals have evolved minds that give us free will and morality. Weaving a richly detailed narrative, Dennett explains in a series of strikingly original arguments - drawing upon evolutionary biology, cognitive neuroscience, economics, and philosophy - that far from being an enemy of traditional explorations of freedom, morality, and meaning, the evolutionary perspective can be an indispensable ally.

In den 1920er Jahren schlug die Stunde der Physiker: Sie machten sich auf den Weg zu den Atomen im Innersten der Welt. Dabei sahen sie sich gezwungen, das gewohnte Weltbild vollkommen aufzugeben. Ernst Peter Fischer erzählt so anekdotenreich wie wissenschaftlich anschaulich und versiert vom großen Jahrzehnt der Physik zwischen 1922 und 1932, seinen genialen Protagonisten und von den ungeheuren Folgen, die der damals vollzogene Wandel mit sich bringen sollte.

Keine Kultur kann existieren ohne eine Erzählung von den Ursprüngen. Der italienische Teilchenphysiker und Bestsellerautor Guido Tonelli erzählt in "Genesis" die große Geschichte von der Entstehung unseres Universums, angefangen vom Big Bang und den allerersten Augenblicken danach bis zu unserem Sonnensystem. Sein Buch ist der meisterhafte Versuch, aus dem Wissen der heutigen Astrophysik heraus eine Erzählung von den Ursprüngen zu entwickeln, die nie die Grenzen der Wissenschaft verlässt, sich aber an den großen Mythen messen lassen kann.

Edwin Hubble was a man ahead of his time. For him only astronomy really mattered. He took advantage of the opportunity given to him to use the most advanced telescope of his time to determine the truth behind the most distant clouds of light visible to Earth-based observers. His major discoveries changed our knowledge of our place in the universe forever. His determination that the universe is expanding served as the foundation for the big bang theory.

From the Ether to the Quantum Field is an essay in which I retrace the scientific development of the notion of the ether, as it dominated 19th century science, to the notion of the quantum field that is the final answer of modern science to the cosmic energy field as well as the human biofield that various researchers have detected and described, and that they all termed differently. Because of the terminological confusion, it was not obvious that all those researchers, from Carl Jung to Harold Saxton Burr, were actually talking about one and the same thing.

Game of Thrones is a fantasy that features a lot of made-up science - fabricated climatology (when is winter coming?), astronomy, metallurgy, chemistry, and biology. Most fans of George R. R. Martin's fantastical world accept it all as part of the magic. A trained scientist, watching the fake science in Game of Thrones, might think, "But how would it work?" In Fire, Ice, and Physics, Rebecca Thompson turns a scientist's eye on Game of Thrones, exploring the science of an ice wall, the genetics of the families, and the biology of beheading.

Three of the most important words in science are I don't know. Not knowing implies a universe of opportunities—the possibility of discovery and surprise. Our understanding of science has advanced immeasurably over the last 500 years, yet many fundamental mysteries of existence persist: How did our universe begin? How big is the universe? Is time travel possible? What’s at the center of a black hole? How did life on Earth arise? Are we alone? What is consciousness, and can we create it?
