Comment on Damping and Damped Harmonic Motion Video – Get out of the way and let us see what you did

Damping and Damped Harmonic Motion at https://www.youtube.com/watch?v=qxDvW8_fm7I Don’t stand in front of the board. Use a laser pointer and stand outside the screen. Your hand waving just gets in the way. Nice presentation, if I did not have to look around you to see the equations and results. You can use a small inset with you,

Comments and Suggestions for Gresham Meggett Oral History Project Kick-Off Meeting, Criminal Law

Gresham College: Gresham Meggett Oral History Project Kick-Off Meeting at https://www.youtube.com/watch?v=a-Ii8Iwc-As This would be much better and more accessible if there were English captions and transcript.

Comment on Houston Astronomical Society website and practices

Debbie, First, your novice videos should be globally public on your website.  Either HAS is an organization devoted to all people knowing about the sky and heavens, or not.  Share openly.  If there are things specific to secure gatherings at private places, those should not be shared, but minimized or separate.  I tell groups like

Comment on Why does light slow down in water

https://www.youtube.com/watch?v=CUjt36SD3h8 You explained part of the problem, but not why it follows those paths. That takes mathematics, and you did not use any.
