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.

hmmm retrohisotricism in all its glory

cool

in the pharmacy a decade ago we were still using manual balances, and had all these tiny squares of bent metal that were like 1g or 5g or whatever. I think 500mcg was the smallest I ever used

You guys aren't going to believe this, but that guy is our games teacher.
Normally I would not recommend Shango066's channel because he is prone to randomly (like once every 20 videos or so) making racist or transphobic "jokes" despite his excellent technical skills otherwise making him very good viewing. In this case, however, he's only in this video for the first minute and the rest of it is about as good a look as you can get at how independent (non-Clear Channel/iHeartRadio/Sinclair) commercial radio stations operate in the current day so please watch this one but be cautious about the rest of his channel:

i am mesmerized by the configuration of this machine.

https://i.imgur.com/D8K4rUt.mp4

the obvious way to scan a book would be to start at the beginning and scan each page one at a time, right? easy, logical, just need a camera and a robot arm that makes the same page-turning motion over and over? maybe some sort of smoothing thing that ensures the page lies flat?

gently caress no. start at the back of the book, vacuum up two facing pages, scan the insides of each one simultaneously with a linear array then flip them to the side and repeat. it's better for the book, it doubles your scanning rate, and there's only one moving part.

that's some sewing machine "what if we used two threads and put the eye of the needle in the tip" poo poo

if the book is just plain text you can just take a video flipping though the pages
