Finally finished my timelapse of the lunar eclipse under the aurora in Fairbanks, Alaska! Check out the massive substorm turning the ground green in front of the eclipse, too!
This is one of my favorite timelapses I have captured!
You should have asked Einstein for that list, he wouldn’t have forgotten cars! Tsk…
Think I got one mainstream media review and it was this. It was for their online site and it was glowing. But don‘t think I even retweeted it. Anyway, here are some reviews from some wonderful people, including some of my writer heroes:
Screenshot of a Desmos graph. It shows many concentric circles which fade out at large radii like ripples or waves. Three colored line segments are intercepting the waves, and data about them is displayed. Two additional points measure the wave intensity and provide ratios of the intensities.
I put together an inverse square law #desmos sim. It includes two intensity probe points for seeing ratios, as well as adjustable collectors/receivers for looking at area and power.
Happy to hear feedback from #ITeachPhysics folks!

A great advert for paying attention in science lessons before working in the Chery marketing department??
This is… insane!
@lewisgoodall.com you seen this from French newspaper liberation? You’d think it would make uk news, but can’t find anything on bbc website
🥶 If you don't mind the (extremely) cold, we're hiring!

My brother fought in the infantry and lost soldiers in Afghanistan. The press used to report deaths before families had been told and I would check my phone over and over, scared it would ring.
I went to the inquest of one of his killed men. I saw his red-eyed parents, girlfriend and baby daughter.
That’s cool!
Students get their favourite meals, carbon footprint down by nearly a third, lower saturated fat, what’s not to like 🤔😊 #STEM

Two days ago it was Elissa Slotkin. Last week it was Jerome Powell. Before that, Mark Kelly. Weaponizing the justice system against your opponents is an authoritarian tactic.
The only person not being investigated for the shooting of Renee Good is the federal agent who shot her.
Hello Bluesky - glad to finally be here! I will post EU institutional and democracy stuff, especially Commission presidentialisation, the (party-)politicisation of EU decision-making, inter-institutional dynamics, and the growing influence of far-right actors in the European Parliament and beyond!🇪🇺
Well that was a game and a half.
Thank you everybody for your support on #TheTraitors. It has been one heck of a ride.
Hahaha! What’s your prediction?
This is what it a computer chip looks like up close
Two social media posts. The first is from Keir Starmer and reads: “The UK has long supported a transition of power in Venezuela. We regarded Maduro as an illegitimate President and we shed no tears about the end of his regime. I reiterated my support for international law this morning. The UK government will discuss the evolving situation with US counterparts in the days ahead as we seek a safe and peaceful transition to a legitimate government that reflects the will of the Venezuelan people.” Below it is a post from Ed Davey that reads: “This cop out isn’t good enough. Standing up for international law means condemning leaders when they break it, whether that’s Vladimir Putin or Donald Trump.”
ATTENTION - derniers jours pour candidater à notre résidence pour créateur.trice ou designeur·e - deadline le 7 janvier.
Venez donc monter un projet de vulgarisation avec mon équipe "La Physique Autrement" ce printemps, tout est expliqué ici :

Love this! Indeed the ‘bed’ unit made its a way in an early paper of the ‘new’ AQA spec at gcse, to much confusion amongst the student body of the time! Nice thing to share in class, thanks for sharing Dan! #iteachphysics
Agreed re stopping using X. We just need more of the big edu accounts to stop posting there and switch to here. There are already many, many small voices like mine on Bluesky, I killed my x account over a year ago
Happy New Year's Eve everyone. If you are a teacher (or indeed anyone) still posting on X, I have a suggested New Year's Resolution for you. Stop!
If you agree, please REPOST here and on X if you maintain an account there.

Thanks for sharing, that will make a great starter question for my a-level projectile motion lesson :) #iteachphysics

Cela fait maintenant 4 ans que ce télescope est dans l'espace et nous raconte l'univers. Il paraît que ce livre raconte bien tout ça 😂
That is awesome, I’m 100% stealing this for teaching a level gravitational fields
