ISI_LISTEN_START
Soyons clairs, Einstein Light explique les théories de la physique en détail et en anglais. Si des sous-titres dans les autres langues sont fournis, c’est uniquement en support pour vous aider à comprendre les informations en anglais.
Comme les informations transmises sont surtout visuelles et sonores, si vous tentez de lire les sous-titres en même temps, vous ne voyez pas ce qui se passe... À force de recommencer, on y arrive, mais le système est loin d’être idéal pour les étrangers.
Ceci dit, les explications sont bien animées, précises et le tout fort intéressant. Idéalement le site gagnera à être utilisé avec de l’accompagnement.
Au programme, (avec des sous-titres en français, allemand, italien, chinois, japonais, russe et espagnol (cliquez sur le drapeau de votre langue)). ISI_LISTEN_STOP
- GALILEO - Mechanics and Galilean relativity
- Do I need to know this? What will I learn?
- An introduction to the mechanics of Galileo and Newton
- Inertial frames and why the laws are the same in the train and on the platform
- The original references, and some caveats and conventions.
- MAXWELL - Electricity, magnetism and relativity
- A little background to electricity and magnetism
- Electricity and magnetism in a moving frame: what would you expect?
- Electricity and magnetism in a moving frame: an electric circuit example
- The electric and magnetic forces between moving charges
- EINSTEIN - The principle of Special Relativity
- Relative to what? What is stationary? The æther?
- The weirdness - and the logic - of the invariance of the speed of light Why Einstein’s relativity is an obvious extension of Galileo’s
- Maxwell’s equations: are they really so beautiful that you would dump Newton?
- But is it true? Is the speed of light really independent of the motion of the observer?
- More about the Michelson-Morley experiments.
- TIME DILATION - How relativity implies time dilation and length contraction
- More about time dilation Is time dilation true? How big are the effects?
- More about simultaneity, and the limits to time order reversals.
- More about length contraction.
- Is the symmetry of time dilation paradoxical? The twin paradox.
- Is the symmetry of length contraction paradoxical? The pole paradox.
- Lorentz transforms, the addition of velocities and spacetime
- E = mc2 - How relativistic mechanics leads to E = mc2
- What do those energy equations mean, and where did they come from?
- Energy in Newtonian mechanics and in relativity
- E = mc2 and binding energies in the nucleus (and in molecules.)
- Why there would be no chemistry without relativity
- Practical devices using relativity
- BEYOND RELATIVITY. (Multimedia version, or smaller html version)
- Relativity and quantum mechanics meet (crash into?) gravity
- Possible variations in the laws of nature
