But it is a mathematically inevitable consequence of the Einstein field equations. A singularity develops.

But in a funny way, you can never observe the singularity and then bring that information back out ("no naked singularities"). So how are you going to do an experiment to demonstrate there's a singularity? You really can't, you get spaghettified and hawking-radiated out a bajillion years later.

This is part of what Penrose and Hawking are famous for! Singularities are guaranteed en.wikipedia.org/wiki/Penrose...

I can't remember where I read good non-technical accounts of this... Probably Susskind's Black Hole Wars. Hawking's autobiography is good but I can't remember if it discusses this.

(oops, also you need vanishing diffusion term to get the sharp cusps)

The KPZ equation is very cool. In the simple case with no noise term, its solution is patched downwards pointing parabolas. I'd like to get a pic where those sharp cusps develop over time but where you can still see some effect of noise like in this pic, but I can't find the right params atm.

You would NEVER catch me up at 4:30am numerically integrating the KPZ equation to draw stromatolites.

Well... maybe.

Lyra!!!

Always a pleasure, especially the amazing discussions of sequels to pirate based games!

:( have a good soup!

Oh thank god

Total resistance from unit resistors This problem is based on, A337517, the most recent OEIS sequence with the keyword "nice". \$a(n)\$ is the number of distinct resistances that can be produced from a circuit with exactly ...

If you like that, you might like this challenge codegolf.stackexchange.com/q/214638/53884 based on OEIS sequence oeis.org/A337517 (the number of distinct resistances that can be produced from a circuit with exactly n unit resistors.)

Oh awesome! Might try my hand. I used some of the code from oeis.org/A048211 which is slightly different. Actually a(5) is the first different number, so I wonder what the unique circuit with 5 resistors that obtains a new value (not obtainable by series and parallel circuits) looks like.

I used slow mathematica code, you have to go to 14 resistors before you can do better than 22/7. I basically just check N cases where N is taken from oeis.org/A000084

If you're given only twelve 1 ohm resistors but you need a circuit with an equivalent resistance of pi (approximated as closely as possible), and you have to use all of the resistors (no shorting or leaving them out), here the ways to get 22/7 ohms (which is the best you can do). #math #circuits

IMMENSELY EXCITED.

Oh, did someone mention Valheim? I can be normal about Valheim. I'm being normal about Valheim right now.

Dastardly.

I bring a "I count as 0 views" vibe to the stream that some stream metrics don't appreciate.

Could you pick me up ten... No, twenty kg of granola. I beg of you.

Brain bug of the last week: I have not seen one person say "Silent Hill Forte" in the wild. I've googled it and seen people saying it there, but that doesn't count. Thank you for your attention.

Introducing the Joel Box, just about done. Little motorized Joel I'll hopefully be able to affix on my TwitchCon badge. I'll also have little Joel pins for anyone that's finds me there!
