Example of the creepy fingers: https://youtu.be/3zoTKXXNQIU?si=MgZgSRFFyxrNGhw3 172.70.175.25 12:58, 24 April 2024 (UTC)

If that's as creepy as Maxwell's Demon gets, you have to wonder if he's related to Gachnar: https://www.facebook.com/watch/?v=3090746901188850 172.70.91.12 14:47, 24 April 2024 (UTC)

Fortunately, Maxwell's Demon can be banished with a silver hammer. 172.69.246.151 15:08, 24 April 2024 (UTC)

Is this a Dungeons and Discourse reference? Psychoticpotato (talk) 18:23, 24 April 2024 (UTC)
Ultimately that'd be from The Beatles... (Don't know that particular D'n'D thing, if that's a thing. Bet that's also a reference of its own.) 172.71.242.70 18:46, 24 April 2024 (UTC)

Thank you, whoever completed the transcript. I didn't know the bullet tag and the comics are starting to get more complicated to explain and transcribe. So again, my thanks. <3 Z1mp0st0rz (talk) 16:12, 24 April 2024 (UTC)

David Acheson showed that any finite number of inverted pendulum segments can be made stable through vibration. related video here: https://www.youtube.com/watch?v=BJ7_fFABc9s&t=0s 108.162.238.131 17:23, 24 April 2024 (UTC)

Considering that Maxwell's demon can reverse entropy, I welcome our new demon overlord. We must all put more starch onto speakers! Fabian42 (talk) 18:10, 24 April 2024 (UTC)

A double pendulum requires 2 weights, and additional one at the center joint. Surprisingly Randal has that wrong. 172.69.60.177 00:25, 26 April 2024 (UTC)

Traditionally, I've seen that fudged by a massive 'link'. In fact, the two pendulum lengths can be dense bars, without even a terminating weight.
This obviously changes the dynamics, as the idealised pendulum has all its mass in the swinging weight at its end (the CoG in its centre), a swinging bar is 'twice as long as its swing-factor' (CoG is half way along). So a two-bar double-pendulum (assuming negligable weight bonus/deficit in the mid-joint mechanism) is a half-length-effect secondary pendulum sat at the end of an extended primary.
As if •-O-•-O-, •=joint (zero mass, zero size), -=extension (zero mass, zero flexibility), O=mass (zero size, zero flexibility)...). This is obviously differently 'tuned' to •—©—O (©=weight+joint, at a point).
...or else the inter-length joint, though not obviously so, is suitably overwhelmingly massive to do weight+jointing. 172.69.43.185 02:25, 26 April 2024 (UTC)
