Intro to theory of resonant reactions + p-p chain reaction (and fairly general theory of non-resonant reactions) in stars. Weak p-p capture leads to deuterons! Fairly heavy theory.. but some practical consequences (i.e., the Sun make energy needed for life, etc.). Pre class slides by Steve Spicklemire.

![A simple Op-amp model with a voltage controlled voltage source.
How to understand an op-amp voltage follower using an idealized voltage controlled voltage source. How does the math work out? (Note there is an error in an equation here at ~5:16, but its pretty obvious. It should be:
