I hope you got a chance to see August’s Corona Lecture, “The Simple Machine Underwater part I,” which was released last week. If you didn’t, you can find it here.

Only a few days into writing part II of what I claimed would be a two-parter, it’s already going long. I can see this thing turning into a three-parter. I guess we’ll just have to see how it goes. As usual, I’m aiming for the next lecture to be out by the end of the month.

Until then, do what the guy who wrote this graffiti says…
