Also, I will release the 3rd learning module, the Albert Einstein Learning Module, on Saturday at noon. It covers only three chapters:
- Light
- Einstein's Relativity
- Modern Atom
You can start reading in chapter 17. I specifically like the "Physics On Your Own" blurb on p. 341, with two pencils and a small mirror. You can try this out. And if you have another small mirror or two, you can make your own retro-reflector like the Apollo astronauts placed on the moon, which is diagrammed on p. 344.
