Il y a 1 jour · Physicist James Clerk Maxwell imagined his demon in 1867 while thinking about how to cheat the laws of thermodynamics. He considered two boxes of gas separated by a weightless door and a tiny ...
Il y a 2 jours · L’expérience originale du démon de Maxwell, énoncée par le physicien écossais James Clerk Maxwell en 1867, implique deux compartiments contenant le même gaz, stocké à la même température. Ceux-ci sont séparés par une porte contrôlée par une entité théorique appelée « démon », qui va permettre de trier les particules selon leur vitesse.
Il y a 4 jours · So, James Clerk Maxwell stated that the advocates of direct action, or action-at-a-distance, argued that at every level of the universe, there is space between the particles at that level, and so interaction therebetween must be at a distance. And this is exactly what Michael Faraday supposed when he proposed a medium in which induction could take place.
Il y a 1 jour · This article inspired further work based on the twin ideas that substances are composed of indivisible particles, and that heat is a consequence of the particle motion as governed by Newton's laws. The work, known as the kinetic theory of gases, was done principally by James Clerk Maxwell, and Ludwig Boltzmann.
Il y a 5 jours · Peter Reid of the University of Edinburgh demonstrates how Maxwells studies of optics shaped our understanding of how we see the world. Professor Harald Haas highlights his influence on wireless communications and demonstrates light projections.

La réalisation la plus importante de Maxwell a été de formuler un ensemble d'équations qui réunissait des observations, des expériences et des équations auparavant sans rapport avec l'électricité, le magnétisme et l'optique en une théorie cohérente [76].
Il y a 2 jours · In a paper published in 1865, James Clerk Maxwell proposed that light was an electromagnetic wave and, therefore, travelled at speed c. In 1905, Albert Einstein postulated that the speed of light c with respect to any inertial frame of reference is a constant and is independent of the motion of the light source. [8]
