Classical physics could not explain the spectra of black bodies. It predicted that the intensity (power emitted at a given wavelength) of emitted light should increase rapidly with decreasing wavelength without limit (the "ultraviolet catastrophe"). In the figure below, the curve labeled "Rayleigh-Jeans law" shows the classically expected behavior.
Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around.

Duke Physics Challenges The following Physics Challenges are for Duke undergraduates and others to enjoy. The motivation for these problems comes from Mark Twain's famous quip that "I have never let my schooling interfere with my education." and similarly I think physics is too much fun to restrict just to classrooms, labs, and homework assignments. If you would like to propose a solution to a Challenge, talk about one of the Challenges, or get a hint, please send me e-mail at email@example.com or drop by my office in the Physics building, Room 097. Please also forward to me any neat problems that you find or invent that would be fun to present as a challenge. Henry Greenside's Duke Physics Challenges
