At the St. Louis Park, MN rally, where there are > 1000 Americans. And two T-Rexs, a Portland Frog, a Tweety Bird, a squirrel and raccoon. And #CaptainAmerica. I had to ask:
me: What would Captain America do?
Cap: He would hold the line.
me: And he'd say - no, you move!
me: What would Captain America do?

Sorry @gailsimone.bsky.social , there wasn't enough space in my new book THE PHYSICS OF SUPERHEROES GOES HOLLYWOOD to discuss Cyclops' heat vision or Superman's force beams. Maybe in the sequel?🤔

Both physics profs who consult for superhero movies and writers of superhero comic books who know their physics enjoy my new book THE PHYSICS OF SUPERHEROES GOES HOLLYWOOD. Bringing people together - it's what I do!😉

My book launch last night at the fantastic Magers & Quinn went great last night. Full house and they even laughed at (some) of the jokes. My new book covers a broad range of physics - from the very big (as in the universe) to the very small (the Higgs boson) and the human scale where we all live.

Well, people are free to debate the question, but it has been definitively answered by Science! (Indestructible Hulk # 10)

After reading Paul Halpern's book on the Multiverse, see how the concept is used in superhero movies. True to its name - there are different types of Multiverses!

One week to go. An all-new exploration of General Relativity and time travel, the Higgs Boson, A.I., why your footprints look dry on the sandy shoreline, active matter, and how LEDs work. Or as computer scientist, author, and current writer of the Fantastic Four, @ryannorth.ca says:

Case in point - the mechanics of Puffer Fish have nothing to do with this JLA story! But Julie Schwartz' "Editors Note" or "Flash Facts" were the early forerunners of hyperlinks.

Sure, it's hot out. But how's the weather in space?

So the first Summer of Astounding Astrophysics went great. Full house, great audience, and very kind (i.e. they laughed at my jokes). Next Tues, Prof. Lucy Fortson, co-founder of the Zooniverse project, will tell how YOU can contribute to cutting edge Astro research (no adv. degrees required!).
