Angry swearing rant
I've been stewing about this for a couple of hours and I just need to vent (will probably delete later):
Fuck you, FCC. And fuck Starlink too. And OneWeb, and AST, and every other horrible techbro company that wants to fucking destroy something beautiful for profit.
I WILL KEEP FIGHTING YOU because you are stupid and selfish and short-sighted and access to the dark night sky is a human right.
When I was a kid I was bummed to find out that "x-ray specs" were a hoax. But astronomers can do it for real!
Here, new infrared images from the Webb telescope pierce the global haze on Titan to reveal the intriguing landscape beneath.

@chatphysics I always like to have ping pong balls, coins and a fibre optic lamp. Coins can be used for radioactive decay and similar.#ChatPhysics
#ITeachPhysics Introducing an idea for the first time it's handy to provide a way to easily remember the meaning, especially for definitions that one just has to remember e.g.
The "independent" variable is the one "I choose". "Independent" starts with an "i" and and so it is the one "I" choose.
Also, provide a simple example they can draw on e.g.
Measuring the period of a pendulum for different lengths, say, 0.4, 0.5, 0.6 m. "I" chose the lengths, so length is the "independent variable".
I pretty sure this is not a correct use of the word “Design.”
On the other hand, “ergobomination” is perfect 👍

Mars is at it's closest to Earth. Here's a photo I captured of it last night using a 14" telescope. You can clearly see the northern polar ice cap! I'm working hard to learn to overcome the challenges of planetary photography to bring you the best images of Mars at opposition.
@JohnBarentine As people build their starter castles with external floodlights as some sort of pathetic echo of a moat, our night sky is slipping from a 1 to a 2. Sigh.
I was diagnosed with #HIV in 1998, when I was 30.
At the time, I did not expect to live to 50.
I’m 55 now.
HIV treatment works and it means I can’t pass it on - we call this #UequalsU.
HIV changed. Tell everyone.

I hold the philosophical position that if two things are indistinguishable, their difference is irrelevant.
"What if we live in a simulation?" -- irrelevant
"What if you couldn't tell the difference between taking to a computer and a real person?" -- irrelevant
But more precisely, it's begging the question to say "imagine something was indistinguishable, now how would you treat it differently???"
A new meta-analysis of "light pollution effect on human health, focusing on the main human pathologies and the types of polluting lights" finds that "the increase in exposure to artificial light triggers mainly sleep and mood disorders, with light from electronic devices and artificial night the main source of pollution."

Retired Chem/Physics/Earth Sciences teacher. I'm interested in everything.
I like a good debate that introduces me to other perspectives. I don't waste much time with people who devolve to name-calling or insults, aside to call them out on it.
I think society performs at its best when we take care of others, especially the weakest among us. That means a strong social safety net, with "free" healthcare, education, and public transit. It's a dream, I know.
30+ years of explaining stuff to teenagers has left me with some habits... I'm not a mansplainer, but I *do* like to find ways to 'splain stuff to receptive ears 😊
I like dogs, cats, and astronomy pictures with a bias towards the shorter wavelengths (kinda leaves out all those lovely Hα pics 😄).
The first thing I look at when shopping for cars is headroom/legroom. Saves a lot of time.
