AHHHHHH SOMETHING ARRIVED IN THE MAIL TODAY!!!!! My early copy of I, ROCK!!! Illustrated by Steph Stilwell, coming June 10th from Beach Lane Books!!! 🤩😍🤩😍🤩 OMG it's perfect. 😭

How does gravity control the motion of our solar system? Move the Sun, Earth, Moon and Space Station to see how it affects their gravitational forces and orbital paths in Gravity and Orbits phet.colorado.edu/en/simulatio... #Astronomy #GravitationalForce #edusky

Sometimes you're goofing off and stumble upon someone's little corner of the web, and something really wows you, and the next thing you know it's three hours later and oh no I think I was supposed to pick a kid up from school. (On here as @rreusser.bsky.social)

The "thanks for paying" screen for my recent endoscopy bill: Me: ... ........ ...Actually, valid question, given everything going on at the moment.

I added 60 (sixty!) more rad science links to The Science Playground. There are so many good simulations, toys, and games out there. Also added a new tab with all the Free Web Links specifically - for your quick dopamine hit of science. thescienceplayground.com/index.php/fr...

SOOTHING BIRD FACT 🐦 Instead of expanding and contracting like ours, birds' lungs are rigid, and air is pumped through them in one direction (making them more efficient) by a series of air sacs.

I have a few more copies. ❤️ Please let me know if you know a kid who could use this message right now and I will send them a signed book for free. (Sorry to have to limit it to the U.S. at the moment.) #KidLit

You probably need an idle game about building up the entire* periodic table, right? Try: The Incremental Table of Elements, by angarg12. angarg12.github.io/IncrementalT... *as I learned from Bond Breaker, only Hydrogen and Oxygen are real elements.

#PhysicsFactlet Do you want an interpretation of quantum mechanics that doesn't really work that well in practice, but that would look fantastic for your Sci-Fi novel? I have for you "Many interacting words" (not to be confused with the similarly named "Many worlds interpretation"). a 🧵 1/ 🧪⚛️🎢

Yay a potential flow panel solver. Variables are source/sink strength distributed along each segment and uniform circulation along the curve. It solves for the values that make flow 1) not pass through the rigid surface, and 2) leave the trailing edge smoothly. 🛫 rreusser.github.io/hess-smith-p...

For your weekend relaxation: 1.5 billion years of plate tectonics in 60 seconds. Fun to locate your hometown (or ancestral town) and track where it's been over the years...or how long it's even existed as a physical location. 🧪 theconversation.com/witness-1-8-...

🎢 A Merry Physmas to All! ⚛️

Could we tell whether anyone in our galaxy uses a warp drive? This sounds like a crazy question, but it can be answered using numerical GR (one of the fun highlights of the annual theory meeting presented by Katy Clough) 🧵1/7

We are looking for players to sign-up and playtest an early prototype: baugarten.game

AI has made it so hard to buy a calendar - suddenly I have to be a detective, inspecting dozens of products super closely to make a small purchase. Super great. Like, technology has always been frustrating when you use it, and now it's attacking unrelated realms... making *them* inconvenient, too.

Terrific new buoyancy simulation from PhET has just been released. Tons of new features and lots of different possibilities for virtual labs with students. phet.colorado.edu/en/simulatio... #iTeachPhysics #EduSky #Physics #PhET

Sometimes you make something just to prove that you can. Behold, a 3D printed physical model of double slit wave interactions! 😅 #iteachphysics 🎢

To follow up on this one -- something interesting is happening with the setup to make these circles...

What better way to ring out a week than with another exciting episode of... "PhIND that PhET!" Which PhET simulation is this nondescript picture from? Answers will only be accepted in the form of OTHER nondescript pictures from this sim.

One star, 12 thousand asteroids. I enjoy how spiral arms start to form, but it's not really connected to how spiral arms really form... (that's more complex that what I've got modeled here, which is just gravity.)

This is a pretty cool way to look at how your computer screen works. I love how unrecognizable it is when you just see the pixels. LCD Display by JavaLab javalab.org/en/lcd_displ...

To add a puzzle twist to this... Why does the orbit precess in the direction it does? Could you think of an arrangement of 3 stars that would make it precess the other direction?

I do enjoy the lacy look the 1/r^2.05 orbit makes after a while... (Feel free to run it yourself: www.testtubegames.com/gravity.html...)
