Eugene Chiang received his undergraduate degree in physics from MIT in 1995, and his PhD in astronomy from Caltech in 2000. He teaches a variety of classes in the Astronomy Department, ranging from introductory astrophysics for undergraduate majors, to fluid mechanics and radiative processes for graduate students, to graduate seminars on galactic and planetary dynamics. The most challenging and most rewarding class he teaches is order-of-magnitude physics, in which the class tries to estimate any quantity under the sun to within a factor of 10.
