The Violent Universe (contributed by Ed Sproles)

Here is another free online class may be of interest:

EdX is running another class taught by Paul Francis and Brian Schmidt of Australian National University.  Brian Schmidt is a 2011 Nobel Prize winner in physics.  The class just started so you can join and catch up.

The class is titled “The Violent Universe” and covers White Dwarfs to Supernovae and black holes.  You can do as much or as little as you like in viewing the lectures and doing the problem sets.

A fun sideline in their courses is a “mystery” world where their universe obeys somewhat different laws.  They disclose a little more each week; it is a puzzle to figure what is going on in this world using the observations provided.

 Just Google “The Violent Universe” to find it in EdX.
