The only other video on her channel is about Bezier curves, so I would assume so.

I'm sure that this has been posted, but this guy and a team of nerds are fixing, rebuilding, powering on and attempting to use the comms equipment from an Apollo spaceship They use vintage test equipment when available as well, so there is tons of HP rack mount oscilloscope goodness https://www.youtube.com/watch?v=v49ucdZcx9s

Got me into electronics as a hobby as well. Defining moments that blew my mind: while he was getting the network card on a xerox alto working, he had the inventor of Ethernet stop by to take a look. in another episode, he was working on some ancient HP plotter/printer. there was an issue with a dip switch, so he took the thing apart and cleaned it/fixed it. had to be at most a 50-cent part but he kept it original he definitely lives up to his name

in some of my classes i teach about splines in the computer sense, and in other classes i teach about splines in the woodworking sense. then i get to explain the connection between them and the history of how engineers reproduce complex curves.

echinopsis posted:i wonder if splines are real or much like maths it’s just some idea humans thought of and has questionable utility but doesn’t really exist splines are absolutely real. this is one:  back in the day, when the most advanced technology on earth was sailing vessel design and the science of hydrodynamics did not yet exist, naval engineers needed a way to accurately reproduce the curves of a ship's hull in technical drawings. this was done by defining a series of points for the curve to go through, which can be easily done with just x,y coordinates, then bending a thin wooden strip (the spline) using those hooked weights so that it passed through each point. because of physics the spline would naturally take the smoothest, lowest-energy path through the points, and this curve could be accurately recreated by anyone with the point list as long as they used the same size and shape of spline to do it. "spline" has the same etymology as "splint," as in the small wooden strip you put on a broken finger etc.
