Problem: Prior to Planck's work, it had been assumed that the energy of a body could take on any value whatsoever that it was a continuous variable. The RayleighJeans law makes close predictions for a narrow range of values at one limit of temperatures, but the results diverge more and more strongly as temperatures increase. To make Planck's law, which correctly predicts blackbody emissions, it was necessary to multiply the classical expression by a complex factor that involves h in both the numerator and the denominator. The influence of h in this complex factor would not disappear if it were set to zero or to any other value. Making an equation out of Planck's law that would reproduce the RayleighJeans law could not be done by changing the values of h, of the Boltzmann constant, or of any other constant or variable in the equation. In this case the picture given by classical physics is not duplicated by a range of results in the quantum picture.
What in making Planck's law was in neither the numerator and denominator of the formula that was used?

Problem: The earthquake was the worst to strike the Sichuan area in over 30 years. Following the quake, experts and the general public sought information on whether or not the earthquake could have been predicted in advance, and whether or not studying statistics related to the quake could result in better prediction of earthquakes in the future. Earthquake prediction is not yet established science; there was no consensus within the scientific community that earthquake "prediction" is possible.
How long since the Sichuan area has had a severe quake?

Answer: 30 years

Problem: In the U.S., for example, copyright case law contains a substantial similarity requirement to determine whether the work was copied. Likewise, courts may require computer software to pass an Abstraction-Filtration-Comparison test (AFC Test) to determine if it is too abstract to qualify for protection, or too dissimilar to an original work to be considered infringing. Software-related case law has also clarified that the amount of R&D, effort and expense put into a work's creation doesn't affect copyright protection.
What test might courts require hardware to pass to determine if it is protected or infringing?
