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.

Ratchet straps can be real pains, especially when they don't want to release easily after you've gotten them into the right places. Having one around to fiddle with is a good idea.
