What Is Fiend's Problem?

The disagreement between Veen's law and experiment is often taught in quantum mechanics classes as the observation that broke the paradigm of classical physics. But for those actually living through this, it probably wasn't all that obvious at this point that this disagreement would be so significant. If we went back and did a survey of physicists in 1900,. I think you'd probably not find many who were really worried about this problem. It was eventually picked up by a big shot physicist at the time, a German man named Max Plank.
