here's a series of videos about Guédelon, a castle being built using 13th century techniques and materials. these show some of the extra stuff, the first five (all I've seen so far) have shown how they made some lime using a lime kiln. french with english subtitles. https://www.youtube.com/watch?v=0xcimgg4IBM

echinopsis posted:can't remember what thread someone recently posted some interactive thing that had bezier curves etc but it reminded me of this neat. i spent a bunch of time a while back working on using spline volume patches (so extending the parameterization into 3 dimensions and creating solid spline volumes) to calculate electric fields. kind of a doomed project, but it was like early covid so i didn't have much else to do other than gently caress around with splines and work on code. gotta use nurbs though, plain 'ol bezier curves can't represent circles

i enjoyed a lot of the videos from joey (the botany guy), he's pretty entertaining. haven't watched them in a while but maybe i'll go through a few recent ones. this one is neat, he's looking for Parasitaxus usta, which is a parasitic conifer. new caledonia has some cool stuff but that's definitely one of the strangest. he finds it at about 14:30 in the video. https://www.youtube.com/watch?v=5xU-lmKUkUc then there's this one, where he looks at some plants around the blighted industrial areas in oakland, and then goes by the homeless camp where he talks about how the cops are harassing the homeless folks who can't afford rent because of all the gentrification. https://www.youtube.com/watch?v=35qF2hEefXg

idk if this is really educational, but i've been checking on this leucistic red-tailed hawk cam occasionally. the bird is really cool looking, leucism is where (some of) the bird's feathers don't get coloration, so she's mostly white. she hasn't layed eggs yet so it's pretty boring right now. you might see her pop in with a branch once a day or something. https://www.youtube.com/watch?v=WQ0mCowoEUI

https://www.youtube.com/watch?v=wJNx9rrv1co it looks like this rov is doing some live dives. they've got a cool camera on the thing, they can zoom in to look at jellyfish and stuff. so far they've just floated around while the biologists rant about whatever jellyfish species are out there, then occasionally hoover up a jellyfish into a sample tube.

Dijkstracula posted:every now and again the algorithm serves me up something good for a change neat. the saddest part of nuclear physics is you can do like hydrogen or simple nuclei, but it's impossible to calculate/solve anything bigger. if you want to calculate stuff from bigger nuclei you just kind of have to make a whole lot of assumptions and it works pretty well, but not really.

FMguru posted:gobekli tepe owns yeah that was pretty cool. beats what happened in the us when they unearthed the mississippian culture around st. louis. there was a highway scheduled to be built through some of the sites so they had to scramble as many archaeologists as they could find and do some emergency archaeology. that video really is impressive with the scale they’re showing and how much is left to be excavated. good poo poo.

idk color is super fuckey. especially once you get out of our lovely electronic displays, they can only reproduce like a third, or maybe a bit more of the possible human gamut. that's why you gotta go look at art in person

yeah i thought about this too, like if you make it your career to be a youtuber how does the middle of your career look? like what does the hydraulic press guy do, he can't keep smashing stuff forever.

yeah and the hydraulic press guy is maybe not the greatest example, he can go back to machining stuff which is what i think he did before the youtube channel. but still, it's not like youtube has a matching 401(k) plan or something so pretty much all youtubers are expendable, exploited, and very vulnerable to job loss. so when they make it their whole life it doesn't really offer great advancement, no safety, and idk if it's really that transferable either.

no they stuck it on a cnc machine and gave it a nice fillet (pronounced fill-it) on the fins. should help it move through the water easier.
