SUMMARY
The Stefan-Boltzmann law, expressed as I = σT^4, was initially derived using classical mechanics by Josef Stefan in 1879, with Ludwig Boltzmann providing a formal derivation shortly thereafter. However, classical mechanics fails to explain the distribution of energy across different frequencies, leading to the "ultraviolet catastrophe." This issue was resolved through the introduction of quantized energy levels in quantum physics, which is essential for a complete understanding of blackbody radiation.
