The paint.net thing is actually so sad to me. I understand many of the valid concerns with AI, but dogpiling and harassing a freeware developer isn't the way to advocate against AI. At best you'll be ignored, at worst you'll turn people against your cause. This isn't an isolated incident either […]

How do I explain to #picaTheCat that I cannot "turn the nor'easter off" or "turn up the sunshine more" on the roof. She meows at the door. I open the door. She meows at the torrential cold crisp rain to "stop at once" ... then at me for not helping.

2. A medium ratchet wrench "I hope it comes loose"
3.  A 2 foot ratchet wrench "I wasn't asking"
4. An angle grinder "You should have listened"

A series of (presumably) Twitter posts by Hannalore Gerling-Dunsmore @JoyOfPhysics

Me, as an undergrad, just starting upper level courses: THERE IS A PROFOUNDLY BEAUTIFUL REASON FOR ALL LAWS OF PHYSICS

Me, as a perpetual graduate student: Light goes that fast because it wants to. 

Me now: light redshifts because it gets tired and blueshifts because it goes weeeeeeeeee going down the gravitational potential 

Me, now: stellar evolution is when the star eats all its favorite snacks and has to move on to progressively worse snacks 

Eventually it runs out of snacks and blows itself up, which is something we can all relate to
