  • human brains use bang-bang control to control our body movement. all muscles are either on or off, with many individually actuateable groups of fibers per major muscle group. if youve ever lifted weights and started to shake on a hard lift, thats your body switching rapidly between different muscle fibers trying to complete the lift. body feedback takes more than 100 ms, which is way too long to do active feedback control on a lot of the really fast actions we do with our bodies, so for those our brain just does it open loop. it generates a sequence based on your intent and past training and just lets it rip, but we for sure can modify the sequence midway.

    this is part of why humanoid robots look so uncanny when they move, they do continuous control which is fundamentally different from how we move our bodies. our brains have special pathways that process others body movements and what those robots do doesnt line up with how we know our bodies move so it looks wrong.





  • eureka. i tried to rewatch it recently and its… oof. one of the main characters has an autistic son who is a savant and they talk about hopefully finding a cure for autism someday. meanwhile pretty much all the scientists and engineers show actual autistic traits that im sure the writers thought were just quirky smart people traits. meanwhile the sheriffs house is voiced by a male character trying to do a womans voice and haha isnt it funny how its kind of inappropriate towards him constantly because its a dude doing a girl voice? then the constant perpetuation of stereotypes, nerd/jock bullshit, and really bad science thats just magic with a technological paint job.







  • they would just burn in those cases. they pop from the buildup of steam inside the kernel, so if you heat them with too hot of a heat source the hull will burn and let the steam out before they have a chance to pop. thats why you need oil when popping corn in most circumstances, to modulate the heat and avoid burning them. air poppers are kind of unique in not needing oil, but they do still tend to burn the kernels slightly and often have more duds than more traditional methods done properly.
