Too much, too much, too much

And what has not been too much, espite it all? My mathematics blog. I'm keeping it to one, maybe two, posts a week, as you know if it's on your reading page or if your RSS reader picks it up. If you just wait for my recaps here, then, here's the recent stuff:

• My Little 2021 Mathematics A-to-Z: Triangle
• My Little 2021 Mathematics A-to-Z: Inverse
• I'm looking for the last topics for the Little 2021 Mathematics A-to-Z
• My Little 2021 Mathematics A-to-Z: Convex

And now ... the finish of my Silver Bells pictures! Close out the drone show and see what I photographed before my camera completely ran out of battery.

Trivia: When learning to juggle Fred Allen bought three silk hats from a magic shop. The proprietor assured him the hats had to be specially ballasted to be juggleable; this weighting cost three dollars each. Source: Fred Allen: His Life and Wit, Robert Taylor.
