I always appreciate these! They show up in live presentations more than in papers, however.

When would we ever use the harmonic mean? Here's one example:

wait what

There is no standard algorithm for calculating sine and cosine. IEEE 754, the most widely used standard for the specification of reliable floating-point computation, does not address calculating trigonometric functions such as sine. The reason is that no efficient algorithm is known for computing sine and cosine with a specified accuracy, especially for large inputs.[53]

Oregon National Guard Adjutant General, General Gronewold says if they are federalized, that he will advise the Title 10 commander to utilize National Guard Troops to PROTECT protesters at ICE facilities. This is the right answer.

An astonishing result, beautifully described in @quantamagazine.bsky.social: the mathematics linking scattering amplitudes in particle physics to a geometric object called the amplituhedron can be better understood by also mapping the amplituhedron to the mathematics of origami.

The amplituhedron, a shape at the heart of particle physics, appears to be deeply connected to the mathematics of paper folding.

Here’s my guess about what will happen: TikTok and younger Instagram users will get inoculated to the effects of AI slop. They won’t recognize every example, but they’ll be suitably skeptical. Older and less-online folks will be taken in more. It will be a new form of literacy, and minds will adapt.

No, but don't worry. It's really on us as math educators to get these things cleared up.

And then there are those pairs of words that are spelled the same but pronounced differently.

There’s a great linguist on TikTok who uses features like this to determine where people are from (when they ask him to): Zay Dupree www.tiktok.com/@zaydupree
Sometimes he tracks them down to a city or part of a state, sometimes to a neighborhood (e.g. in New York City)!

I say “naught” usually rhymes with “caught,“ but “caught” can be pronounced differently in different places. In some places it’s more of a closed vowel, and “cot” is more open, but in others they’ve moved towards each other in sound, and can be indistinguishable. Hence the “cot-caught merger.”

Joshua Bowman @thalesdisciple.bsky.social · 5d

In the U.S. it varies by region. “Nought” is unusual enough that I’m not sure how most USians would say it. Here it’s more common to use the spelling “naught” and rhyme it with “caught.” But “naught” is unusual, too, outside of idioms like “it was all for naught.”

the truth is always in between the extremes. that is why mathematical objects should be indexed starting with 0.5

Tired: the smallest natural number is one.

Wired: the smallest infinite cardinal is aleph-one.

Jessamyn Dukes @rhymeswithspecimen.bsky.social · 5d

this is why indexing should always start at 1

After a couple of votes for “x-nought” in the comments, I did some research and determined that either naught or nought is acceptable.

Whether their pronunciation is the same or different, I’m not sure.

Joshua Bowman @thalesdisciple.bsky.social · 7d

TIL at least some of my students believed x_0 was read as x-not, rather than x-naught.

Is this more common in places with the cot-caught merger, or does that not make a difference? Is it just because “naught” is an archaic word?

The real question is, how did zero come to be both “naught” and “aught”?

Oh yes, the students were thrilled when I pointed out that “aught” and “ought” are also spelled differently.

It's not knot, but also not naught. It's a little bit nautical, but also somewhat naughty.
