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.

Whether searching for extra-terrestrial life, managing the effects of space weather or learning about dark matter, the study astrophysics has profound implications for us all. NASA scientist and astronomer Sten Odenwald explains the key concepts of this vast topic, bringing clarity to some of the great mysteries of space.

" 18 avril 2018 : Shojiro Takejama appuie sur le bouton rouge qui déclenche son expérience. Boum ! Dans l'explosion qui s'ensuit et qui manque de détruire le laboratoire, le chercheur parvient à produire le champ magnétique le plus intense au monde : 1 000 fois celui qui règne dans un tunnel d'IRM.

Quant’è grande l’universo? Da che cosa è composto? Com’è nato? Come evolverà? Il libro accompagna il lettore in un percorso che parte da ciò che sappiamo per poi addentrarsi nel territorio sconosciuto dei grandi misteri del cosmo. Un viaggio sorprendente che apre nuovi orizzonti, svelando che dietro l’apparenza luminosa e sfavillante di stelle e galassie si nasconde un universo costituito da componenti di natura ignota.

Too often, textbooks obscure the beauty and wonder of outer space with tedious discourse that even Galileo would oppose. Astronomy 101 cuts out the boring details and lengthy explanations, and instead, gives you a lesson in astronomy that keeps you engaged as you discover what's hidden beyond our starry sky. From the Big Bang and nebulae to the Milky Way and Sir Isaac Newton, this celestial primer is packed with hundreds of entertaining astronomy facts you won't be able to get anywhere else.

"The Beginner's Guide to Parallel Realities" transforms mind-bending concepts into accessible insights that will forever change how you view reality. Using clear examples and engaging thought experiments, this guide breaks down complex theories about the multiverse, time travel, and alternate dimensions into digestible pieces that anyone can understand.

This text revolves around a new and unusual view on the most fundamental puzzle of physics. It focuses on the key aspect that makes the role of the time dimension fundamentally different: causality. The implicit and intuitive way by which causality is usually taken for granted is just made explicit and less self-evident, shedding a new light on the gravity-quantum conflict. The case is made that gravity is a necessary condition for a causal universe.

This is a journey into the mysterious and transformative world where science and spirituality converge to illuminate the profound nature of love. In this book, we explore how the same forces that bind atoms and particles can also explain the magnetic pull of soulmates, the deep connection that transcends time and space, and the inexplicable resonance we feel with certain people.

Un delicioso ensayo que nos adentra en las particularidades de nuestro bien más preciado: el tiempo. ¿Por qué algunas horas pasan volando mientras otras se alargan infinitamente? ¿Por qué la sensación del tiempo transcurrido se diluye inexorablemente ante el tedio y en cambio se desvanece en los momentos de gozo? Hace tiempo que la ciencia definió el tiempo como algo relativo y sin embargo sigue siendo nuestro bien más escaso. Lo prueba el hecho de que somos la generación que más tiempo tiene para sí misma y sin embargo vivimos subyugados por el ritmo incesante de las agujas del reloj.

Vier Forscher und ein unablässiges Hin und Her der Ideen – vor hundert Jahren entstand eine neue Wissenschaft, die die Grenzen der Vorstellungskraft sprengte: die Quantenphysik. Ihre Protagonisten: Max Planck, Albert Einstein, Niels Bohr und Werner Heisenberg. Sie ergründeten das Innere der Atome und rangen mit einer scheinbar einfachen Frage: Was ist Licht? – zu einer Zeit, in der Elektrizität erstmals die Städte erhellte und Kino und Fotografie ihren Siegeszug antraten. Thomas de Padova lässt die fieberhafte Suche nach Antworten anhand der Begegnungen der Forscher lebendig werden.
