Applied Science is just a really smart guy who works (worked?) at Valve who reads cutting edge research papers and tries to recreate it in his home machine shop / garage. I just discovered Not Just Bikes a few weeks ago, and I'm really digging his content. He complains and rants too much for me to really binge his channel, but I still go back to it for small doses. I'll work my way through his catalogue eventually! I do like Technology Connections, but I'm a mechanical engineer by training so a lot of his videos don't really cover new stuff for me, or it's a 22 minute video for 8 minutes of real content. He tends to go over each concept repeatedly from sliiightly different perspectives each time. Which is cool, but I end up skipping around in the video until he gets to the point.
