Wait, so I'm not the only one who thinks about this? [[Special:Contributions/172.71.167.177|172.71.167.177]] 23:28, 17 January 2024 (UTC) | Wait, so I'm not the only one who thinks about this? [[Special:Contributions/172.71.167.177|172.71.167.177]] 23:28, 17 January 2024 (UTC) | ||

This sounds like the premise of the 1966 sci-fi story The Revolving Boy by Gertrude Friedberg. I recall reading it sometime in the 1960s or ’70s. I wonder whether Randall has read the book too — https://solarbridge.wordpress.com/2011/05/19/the-revolving-boy-gertrude-friedberg/ | This sounds like the premise of the 1966 sci-fi story The Revolving Boy by Gertrude Friedberg.

I feel like the "worldline torsion" line needs to be explained moreso than the OCD thing, since "worldline" is a word people might not know and it's the crux of the joke.

The CPSC recommends merry-go-rounds be limited to 13 ft/sec. https://www.sportsplayinc.com/images/cpsc.pdf For a 10 ft radius, that would be one rotation every 4.8 sec. Over "one long afternoon" (which I'll take as 6 hours) that would amount to 4,469 rotations. If you compensated for this with a mere one rotation per day, the excess rotation would be completely offset in 12 years and 3 months, so "decades" is quite an exageration.

It makes me think a lot about [[162: Angular Momentum]] [[Special:Contributions/141.101.98.34|141.101.98.34]] 19:45, 18 January 2024 (UTC) | It makes me think a lot about [[162: Angular Momentum]] [[Special:Contributions/141.101.98.34|141.101.98.34]] 19:45, 18 January 2024 (UTC) | ||
