Week 19, Day 2: Beauty

EVEN BLOCK PERIOD. Notes on Stars and Galaxies and review HR diagram homework.

"A thing of beauty is a joy forever"

We have got to use beauty when ever we can in our classes. Why would you use a chart like the one shown below when you can use the beautiful one on the right.

An HR (Hertzbrung-Russell) diagram is just a graph of all the stars we have data on, plotting their Luminosity vs. their temperature. 95% of the stars fall on that line. THERE IS ORDER IN THE UNIVERSE.  We know that but this chart lets us SEE IT!.
