In the last physics lesson, the teacher seemed to have to explain the Doppler effect for quite a long time to some people before they understood it. So, being the nice, considerate, thoughtful person I am, I decided out of the goodness of my golden heart to explain the Doppler effect for future reference using animation (actually, I thought it would be a fun thing to do anyway). For those of you who are confused about what the Doppler effect has to do with anything, it's red shift and blue shift. So it is relevant to the lesson.

Vid Description:"This scene from PBS's NOVA program, Episode "Einstein's Big Idea," demonstrates Albert Einstein's use of "thought experiments" to help visualize complex ideas at the forefront of science. This scene also shows Einstein as a young, passionate visionary, rather than as the stale, gray old man he is universally known as today." Students wanted to see the whole movie...please let me know if you come across it.
