I have a recurring fantasy that a sorcerer splits the timeline in such a way that everyone who sincerely believes that the world would be happier without some other set of people gets their wish. Afterward many of us, perhaps most, live in many successor worlds at once, and share memories when we sleep.

Ya, after you answered it occurred to me that I could have looked up “Schild's ladder (not the novel)”

Yes, thanks. How did you guess?

I want to read about a certain mathematical concept but cannot recall the word for it. Then I remembered it's described in «Schild's Ladder» by @npub12cu…d38p … but where is my copy??

@npub1nzj…pmgc This reminds me of «Blade Runner» (the novel by Alan Nourse, which is unrelated to the movie of the same title, which is based on a story by Philip Dick).

The AMS link is broken; did you leave out a space before “AMS website”?

A few months ago I happened to see, close together in time, two or three videos that said this or that animal can run at 18.6 mph.

I watched it in 2004 and blogged in part:
The first half of the picture, though slow, was rather interesting to me because most of the foreigners speak Spanish, French and English, as the mood takes them; I wonder how realistic that is.

The Grassmannian is the space of orthographic projections from a Euclidean space to one of lower dimension; the set of k-dimensional planes passing through the origin in E^n. By forbidden arc (my mistake, it has more than one degree of freedom) I mean a continuous set of projections that make the images of some elements collide.

You want a projection of the 5-cube that maximizes the minimum projected distance between a vertex and a non-incident edge. I think that means finding Voronoi points between forbidden arcs in the Grassmannian.

When I first read of the idea of Einstein rings, the description ended with: how striking that would be, too bad we'll likely never find one.

In 2006 I reorganized “Enclave” and “Exclave” into “Enclave and exclave” and “List of enclaves and exclaves”, to lessen repetition and bulk. Likely the most ambitious single thing I ever did on Wikipedia. @npub1k6n…wl5m
