The Ultraviolet Catastrophe

The ultraviolet catastrophe was a significant problem in late 19th-century physics that arose from the failure of classical physics to adequately describe black body radiation. According to Rayleigh-Jean's Law, radiation intensity would rise infinitely as wavelength decreased, which contradicted experimental observations that showed intensity declined after a certain point. This discrepancy frustrated physicists, as neither classical model adequately explained the behavior of black body radiation across the spectrum. The failure to resolve this issue highlighted the limitations of classical physics and set the stage for revolutionary changes in the understanding of energy and matter.

During the late 19th and early 20th centuries, there was a problem that stumped even the best minds in physics.

Eventually, one man, Max Planck, solved the problem, but his solution was one that was out of left field. While the math worked, he didn’t actually believe that the mathematics explained reality.

It turned out his discovery was more true than he realized and it ushed in a revolution in the world of physics that completely changed our view of nature and reality.
