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.)
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'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

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!

I ordered a couple of small metal prints of some of my sculptures from Craftcloud (IN3DTEC was the printer). Spendy (and don’t forget the extra $30 in tariffs!), but they came out looking pretty darn spectacular!

Anyone post #math challenges on here? This integral (said to be due to Joseph Bertrand) posted by ChetuyaGamma on the other site hooked me. (I think integrating via contour is consider the coward's way out, but I like the wiggly lines okay?)

Had to pause the latest #3blue1brown video after the 10 seconds to try to solve it myself.
Given an n cube, how many unique connected partial n cubes can we construct out of (n-k) faces? (This is rhetorical, I'm trying it and will try to bumble my way through the computations)

Twitch affiliate anniversary coming up on Friday. 8hrs of math? I'm feeling combinatorics + analytic comb. + comb. algorithms (including absolutely stupid stuff like renting out a 4x5090 server and running a brute force n-queens enumeration algorithm on it).

i think i never posted about this here amidst the chaos of traveling but a month ago i saw the extremely rare vancouver island marmot (marmota vancouverensis) in what i think was easily the most amazing wildlife encounter of my life

I have a lot of people to thank for my journey, but I have to say the minimal polynomials of cos(n pi/m) made me into the man I am today. Well no, but can you imagine?

One of the more obtuse ways to calculate Fibonacci numbers. My determinant formula circled in green gives rise to the recursion r -> 1+1/r. The fixed point r=1+1/r is solved by r=phi, the golden ratio
