Extra Help Session for Exam II

John is offering an extra help session this week for people who want to go over material for Exam II.  The help session will be Wednesday, October 17, 2-3 p.m. in Business Leadership Building room 090 .

The exam will be Thursday morning at 8 a.m. and will cover Chapters 5-8 (although I ran out of time and the exam will not cover section 8.5).

Happy Birthday Niels Bohr

Last week I introduced the Bohr model of the atom.  Neils Bohr would have been 127 years old today. In commemoration, this was the doodle art on Google.com today:

Hopefully you can recognize and understand some of the symbolism in this figure.  See if you can figure it out.  We will discuss in class.
