Here it is - our last show for this school year. Thanks to all my students!

Video review of the critical angle concept. This is why we use prisms instead of mirrors in binoculars and periscopes.

Video review of Snell's Law. We show how to calculate n, theta i and theta r.

Here we have a brief video review of reflection and refraction.  Produced using a new software package, so the audio has some issues with low bitrate.

A memorial to one of my best students who died in heart surgery last weekend.

We're back! Well I'm back after a break for buying a new house and starting to move. A brief look at what's been happening, and how we'll finish the school year.

A quick video review of pendulums and springs from last week.  This is a whiteboard lecture - just like being in class!

Our first podcast of the spring semester. A look at pendulums, springs, and our first week. Then, I answer listener email questions about broadcast standard levels and the tools I use. Nerdy music from The Science Groove and music.podshow.com.

Today I talk about what you need to be successful on the final exam, and we have random ravings of the lunatic mind. Music courtesy of music.podshow.com.

Here are 100 questions that could show up on the final next week.  Study hard!  Answer key included!
