Let's skip on to two other videos. Each of them quite different from the others.

• First is Sal exploring the origins of the French Revolution. It's actually longer than most of the videos at 17 minutes. You obviously don't have to view any more than you want. But you might find it fun to fully view sometime. It says a lot about Sal's special skills as a teacher.
• The third video is titled "The Birth of Stars" - it doesn't back away from its title and does take us clearly into the modern science of cosmology.
