Lecture 2: Astronomical Numbers
An introduction and review of the basic notation and physical units we will be
using throughout this course. In particular, we will be using the
Metric (SI) system for lengths, masses, times, and temperatures, and
special astronomical units for distances (AU and Light Years) and masses
(Earth Masses and Solar Masses) appropriate when discussing
interplanetary and interstellar scales. Recorded live on 2009 Sep 24 in
Room 1005 Smith Laboratory on the Columbus campus of The Ohio State
University.
