Thank you, Dr. Andersen, for your wonderful lesson on Physics and Space. I'd be lyin' if I said I understood any of it (sigh... my background is in a totally different area), but I'm thankful that you are joining the discussion here, and making your contribution(s). I hope you will continue to provide us with teachable moments. Physics and the hard sciences are just as important as our (occasional) bombastic confrontations over who's winning the Election, and whether Kamala Harris has the stuff to be a good Vice President (or not).
