The analogy doesn't seem to be inaccurate in the way currently indicated. In both cases (tape measure and pulsar), conservation of ''angular'' momentum is what produces the result. With the tape measure, a small fast-spinning thing turns into a large slow-spinning thing; the opposite happens with a pulsar.

I tried applying the right-hand-rule with the y-axis pointing to the right. :( I hurt my hand.

- Rotate your paper then do the right hand rule :)
- Hand joint exercises. Gentle motions with the wrist bent backwards, and bent forwards; 3-5 circles in both directions and both postures, twice a day. 162.158.62.41 00:48, 19 January 2021 (UTC)
