Rayleigh-jeans law derivation
Webderivation of the Plank constant from the Rayleigh-Jeans Law is beautiful. 2. Your discussion on Quantum Mechanics is right on the mark for a non-physicist. 3. Boy, are you going to get hammered by the scientific high priests. Your suggestions are bold. What I find the most appealing in your book is the In 1900, the British physicist Lord Rayleigh derived the λ dependence of the Rayleigh–Jeans law based on classical physical arguments, relying upon the equipartition theorem. This law predicted an energy output that diverges towards infinity as wavelength approaches zero (as frequency tends to infinity). Measurements of the spectral emission of actual black bodies revealed that the emission agreed with Rayleigh's calculation at low frequencies but diverged at high frequencies; …
