La physique quantique

La séparation des pouvoirs est un concept fondamental en philosophie politique et en droit, qui vise à éviter les abus de pouvoir. Il repose sur une idée simple mais puissante : il ne faut jamais confier tous les pouvoirs à une seule personne ou à un seul groupe, car cela conduit ... Show More

La “main invisible” est une idée célèbre développée au XVIIIe siècle par Adam Smith, philosophe écossais considéré comme le père de l’économie moderne. Ce concept apparaît principalement dans son ouvrage "La richesse des nations" (1776), et il reste aujourd’hui au cœur de la pens ... Show More

Les Barbaresques étaient des pirates originaires du Maghreb, notamment des régions côtières actuelles de l’Algérie, de la Tunisie, du Maroc et de la Libye. Leur nom vient de « Berbères », les populations locales, mais aussi de l’appellation européenne des côtes d’Afrique du Nord ... Show More

Sean Carroll is creating a profoundly new approach to sharing physics with a broad audience, one that goes beyond analogies to show how physicists really think. He cuts to the bare mathematical essence of our most profound theories, explaining every step in a uniquely accessible ... Show More

Melvyn Bragg and guests discuss the German physicist who, at the age of 23 and while still a student, effectively created quantum mechanics for which he later won the Nobel Prize. Werner Heisenberg made this breakthrough in a paper in 1925 when, rather than starting with an idea ... Show More

"There is nothing new to discover in physics", declared the British physicist Lord Kelvin in 1900. That is no longer true. Today it is becoming increasingly clear that there are problems that physics, as we know it, doesn't seem to be able to solve. Perhaps we just need more data ... Show More

Publication week! Say hello to Quanta and Fields, the second volume of the planned three-volume series The Biggest Ideas in the Universe. This volume covers quantum physics generally, but focuses especially on the wonders of quantum field theory. To celebrate, this solo podcast t ... Show More

Nassim Haramein, a veteran physicist working on one of the most complex and difficult problems in physics, describes his insights into our holographic universe, consciousness, and zero-point energy. He discusses fundamental principles of spacetime and the groundbreaking discovery ... Show More

In the 1860s, James Clerk Maxwell argued that light was a wave of electric and magnetic fields. But it took over four decades for physicists to put together the theory of special relativity, which correctly describes the symmetries underlying Maxwell's theory. The delay came in p ... Show More

What is the nature of quantum physics? Neil deGrasse Tyson and comedian Chuck Nice get quantum, exploring Schrodinger’s Cat, electrons, Hilbert Space, and the biggest ideas in the universe (in the smallest particles) with theoretical physicist Sean Carroll. NOTE: StarTalk+ Patron ... Show More

In this episode, we cover the topic of work and energy. We’ll start off by talking about work, which includes the mathematical and conceptual definitions and the sign convention of work. We’ll also talk a little bit about mechanical advantage and also path dependency. Moving on t ... Show More
