Here is a list of all my public writings and videos.
If you want to do a dialogue with me, but I didn't check your name, just send me a message instead. Ask for what you want!
There's something about the way you write introductions that reminds me of good YouTube videos. It's a combination of easy-to-understand illustrations, simple words, and starting with an interesting question.
To measure the period of a pendulum, the pendulum must leave a position and then return to it. The pendulum is not leaving its current position. Therefore it is incorrect to conclude that the pendulum's period is 0.0 seconds.
The students should continue monitoring the pendulum until it leaves its position and then returns to it.
I think the Dialogue feature is really good. I like using it, and I think it nudges community behavior in a good direction. Well done, Lightcone team.
The points you bring up are subtle and complex. I think a dialogue would be a better way to explore them rather than a comment thread. I've PM'd you.
I know all of those words. I'm not super-comfortable with "chicanery", but it didn't cause any issues with my reading. Please click [agree] on my comment if you know all three words and [disagree] if there is at least one you don't know.
