I wish, in school, teachers would have taught us things like this, how gears are just concurrent levers, how cams introduce asynchronicity to an operation. This is stuff I only started learning from working on and learning about cars.

I remember even when I was in school (a good time ago now), they were already killing off shop classes and the like. How sad that schools couldn't see what values classes like that have in critical problem solving.

They could. The bureaucrats didn't, and moreover didn't care.

I took a hands on physics class in high school (elective at a magnet school) called power and energy, in which we took apart, cleaned, and put back together an engine as our semester project, as well as learning all the math and physics behind the way in which they operated, how to calculate pretty much everything they did, etc.

It was an enormously valuable class in learning, fairly early on in my proper STEM education, how a system could be made up of many moving parts and subsystems - an obvious boon to my work today in software.

Contact your local school board and state education agency. The schools I have taught at still have these classes (automobile mechanics, applied physics, etc) because parents fight for them.

They are probably still able to legally be offered as courses (states usually don't remove entire course from state standards. The just go unupdated). School boards like to remove these courses because they are expensive (among other reasons) and on paper they look unpopular (hard safety caps mean a 15 person shop class looks unpopular compared to a 45 student overfilled history class).

Schools and school boards are parts of the government most susceptible to public pressure.

As a teacher, I want parents and community members to lobby their local schools. They don't listen to teachers but they buckle to parent complaints[1]. Please use your "complaining" powers for good.

[1]Unfortunately, schools can have a bad habit of viewing all parent contact as "complaints" or "whining."

Jam Handy is under-appreciated in my opinion [0]. I wonder how videos like this would be received today. 0. https://en.wikipedia.org/wiki/Jam_Handy

Ten years ago I also would have wondered. Now I know; there are a lot of fine YouTube channels of a similar nature. It is certainly true that one must filter through a lot of garbage to find them, but they are there. Different topic, but here's just an example to get you started: https://www.youtube.com/watch?v=KfuARMCyTvg

I was in a Soviet school system (it was towards the end). And somehow we had a really fun shop class. We did stuff with electricity. Had a lathe, wood and metal. Remember making our own hammers. Learned to use a coping saw, a wood plane. School was remodeling so they let do demo work. Totally unsafe but loads of fun. Didn't learn about cars much though.

We had so many things there that would be considered unsafe and dangerous these days for US kids here I'd imagine. Same thing with chemistry experiments. Though interestingly there more encouragement here to play contact sports like football which leads to concussions and injuries.

Same video over and over again https://hn.algolia.com/?query=differential%20gear&sort=byPop...

Hey, its the first time I saw it. Nice stuff. Should be recycled.

Wait you didn't see this when it was posted the first time 8 years ago? Then you clearly shouldn't get the chance to see it again.
