Mapping the Milky Way: William Herschel's Star-Gages
Todd Timberlake
In 1785 astronomer William Herschel mapped out the shape of the Milky Way star system using measurements he called "star-gages." Herschel's star-gage method is described in detail,…
Comparing periodic-orbit theory to perturbation theory in the asymmetric infinite square well
Todd K. Timberlake
An infinite square well with a discontinuous step is one of the simplest systems to exhibit non-Newtonian ray-splitting periodic orbits in the semiclassical limit. This system is a…
Computation in Classical Mechanics
Todd Timberlake, Javier E. Hasbun
There is a growing consensus that physics majors need to learn computational skills, but many departments are still devoid of computation in their physics curriculum. Some departme…
Is there quantum chaos in the prime numbers?
Todd Timberlake, Jeffery Tucker
A statistical analysis of the prime numbers indicates possible traces of quantum chaos. We have computed the nearest neighbor spacing distribution, number variance, skewness, and e…
