β€˜Hey’ came before β€˜hi,’ and β€˜hi' came before β€˜hello.’

β€˜Hi’ is most likely a variant of β€˜hey.’

β€˜Hello’ is not related to either.

Goodbye.

While electrodynamics is well understood, there aren't many scattering problems we can actually solve. A plane wave scattering from a uniform dielectric sphere is one of those few, and the solution was originally found by Gustav Mie in 1908.

arctrig

I do love that the arctrig functions do translate to actual arc lengths, though.

Pam from the office meme, but it’s Einstein: 

corporate needs you to find the differences between this picture and this picture -

1) cartoon of dropping a ball on an accelerating rocket.
2) cartoon of dropping a ball on earth.

Pam with einsteins face: they’re the same picture

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.

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.

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.

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 usβ€”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 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.

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.
