things for which I have no intuition
... include "angular momentum" (yes, despite having sat on a spinny chair and done the thing; yes, despite having worked through all the maths multiple times; yes, this is awkward for several of my flavours of science) and "ratchet straps".
The latter is increasingly inconvenient given the existence of my terrible tent-based hobbies.
So! A has been threatening me with the concept of a Tiny Ratchet to add Enrichment to my Environment for a while, and a few days ago (courtesy of the car getting a spa treatment) a tiny ratchet did indeed wind up on the sofa, where my feet normally go.
It has spent the entirety of those days Not Biting Me even though I squinted at it suspiciously, so this evening we moved on to the next step of "staring intently at all the moving parts while fiddling", with Supervision from a Responsible Adult.
So far I think it is going better than angular momentum? I am potentially willing to grudgingly concede the existence of ratchet straps. The tiny baby (0.28 tonne) ratchet will continue to live on the sofa so I can intermittently pick it up and continue fiddling suspiciously. Maybe I will manage to internalise enough of the workings to feel slightly more confident being handed the ten-tonne ratchets in a few weeks' time...

Ahh, I learned about these on the job, as it were, riding paratransit. Drivers are required to secure wheelchairs to floor with four “tie downs” — ratchet in a strap with heavy duty hook to scratch your caster fork or rear undercarriage.

I've spent a lot of time being strapped down with them on public transport, yes! Alas this has done NOTHING for my ability to apply them myself.
