A simple finite element simulation of a pulse scattering on a small (but not point-like) dielectric obstacle.
The scatterer behaves approximately as a re is a very faint halo of light going everywhere, but most light gets diffracted into something similar to a Airy Disk.

i'm disappointed but not shocked that this time capsule from 2016 is not only still true, but maybe even more true
A lot of people say AI isn't very good for the world and its outputs are routinely unreliable, but these haters fail to see how it's revolutionizing how we incinerate schoolchildren.
I think about this take more often than I'd like to.
PRIMARY TEACHERS! This "disappearing rainbow" works because of the way light is refracted and totally internally reflected - the same phenomena at play in the making of a real rainbow. It's a demonstration you can use to explore / explain rainbows to your students. More in the link below.
Our students came up with a creative solution to measure a force with a smartphone and phyphox.
NEW. This is an elementary girls school in the city of Hormozgan in Iran.
In the last hour, it was hit by a US/Israeli missile attack.
So far, 24 young girls are confirmed dead [SOURCE: Al Jazeera].
The US has just committed a war crime.

winter sun shines high above a circular still water tank at a sewage treatment plant. The sky is blue with puffy clouds and brick buildings are on the distant horizon. the sky and sun reflect off the water in the tank. the foreground seemingly connects to the distant buildings as a catwalk on the left extends from out-of-frame bottom towards the horizon.
sewage is water with life experience.
it reflects the choices we make and carries with it the residue of our yesterdays and years.
it can unsettle us—until we realize it was once a part of us. our pasts make us who we are today.
and can inspire us to be better tomorrow.
Please read this article to the end. Even before ICE got involved, this started because this *blind man who speaks no English and uses a curtain rod as a walking stick* got lost on a walk and some Karen called the police on him and they tasered and beat him bc he didn’t drop the rod. WTF

I'm launching a new project on how A.I. is changing writing instruction. Professors and high school teachers -- we need your help! Please fill out this brief survey: www.nytimes.com/2026/02/23/u...

I'm constantly trying (/failing) to get this point across.
If you're a trained expert in a field, then it may be worthwhile to question the scientific consensus of your peers.
If you're not, the scientific consensus is absolutely the best you can do and it's arbitrary foolishness to disregard it.
NEW: Meta’s director of AI safety, supposedly the person at the company who is working to make sure that powerful AI tools don’t go rogue and act against human interests, had to scramble to stop an AI agent from deleting her inbox against her wishes...
"The strategic initiative has a bigger plan for us all. You’re suffering now, but if you fight through the pain and work extra hard in support of the new strategic initiative, you’ll taste the sweet afterlife of a successfully executed strategic initiative."

Why do I have to pretend that I'm going to print something in order to save it as a PDF. Why do I have to engage in a little ruse.
When my daughter’s school suggested she use AI to help her prep for tests, she replied “I’d rather fail than use AI.” 🙌

Because in 2012, a US District Court ruled that New Jersey common law postmortem publicity rights endure for no more than 50 years after a person’s death. Because Einstein died in 1955, the Court’s ruling means that Einstein’s publicity rights are now in the public domain.

WHY ARE THEY ALLOWED TO USE EINSTEIN’S IMAGE LIKE THIS???? THE ESTATE SHOULD SUE

Nice! Got some good looking data from @flippingphysics.bsky.social Shoot and Drop video.
Incredible new motion tracking online app: phystracker.org Check out that "Analysis" tab! #iTeachPhysics
Hey! Scholars! If you're using someone's work in your class, sometimes it's nice to email them and tell them, because then they might feel good about their research instead of entirely crushed by the academic humanities' ongoing descent into the grave
Alysa Liu telling 60 Minutes “I love struggling, it makes me feel alive” is a legit revolutionary statement from a Bay Area native in a time when copious amounts of time and resources are being put toward convincing us to opt out of experiencing struggle, friction and self-actualization
There's so many physicists here on Blusky yet I never see any real discussion or dialogue on any physics topic despite following the physics feed and every physicist in my areas of interest.
Am I missing them? What can we do to spark some physics conversations?

Infographic titled “The 2026 Winter Olympics medals” shows gold, silver and bronze medals with ribbons. Gold medal value is $1,938 / £1,437 and is 500 g silver with 6 g gold plating. Silver medal value is $1,003 / £744 and is 500 g of 99.9% silver. Bronze medal value is $5.13 / £3.81 and is 420 g copper. Text notes medals use recycled metals from the Italian State Mint and have protective coatings.
As the Winter Olympics draw to a close, what are the medals that the top athletes will be taking home made of? This graphic takes a look and also highlights the values of each medal: www.compoundchem.com/2026/02/22/w...
