I don't know why I never tried experimenting with Villarceau circles before. Even the simple operation of uniformly spacing them on their corresponding torus makes for a nice woven appearance.

For some reason, I've gotten drawn into reading Paul Graham's essays again. paulgraham.com/procrastination does jive with my experience of postponing sorting out my books (or actually, the room I'm in) just because I was obsessing over whatever I was working on at that moment.

I forgot that I did this cartoon of a circle rolling on a parabola years ago. I should really find time to modernize it.

Quite a while ago, @11011110 wrote about the Wankel rotor. That reminds me that I should really find the time to clean up my write-up on the Bernoulli-Euler double generation theorem for cycloidal curves.

Sometimes, I still get befuddled by how "it sucks" and "it blows" can mean the same thing.

I made a domain coloring plot of one of the functions I'm currently studying. It looks quite mesmerizing.

My (admittedly very minor complaint) about is that when you have papers of interest in different sessions, Zoom doesn't allow you to be in two different meetings. This makes me have to repeatedly leave and join sessions.

For all of the general crappiness of this pandemic, I have to admit that if not for it, I would not have been able to attend otherwise.

From a monograph I'm currently reading: "(This book) has been written for the technologist, and is not addressed in any sense to the pure mathematician, for whom I am not qualified to write. Between the outlook of the two parties lies a gulf as wide as that between sinner and saint or vice versa!"

It's really sad when the book you need for research is out of print, and all the nearby libraries that do have it are currently shut.

OK, for some weird reason, I couldn't access Mathstodon for an entire day even though pinging it with another website shows that it's up? Must've hit some IP block... o well.

With that being said, there are at least two applications out in the wild that are using algorithms I've devised but never (formally) published or described. I hope they're doing well.

I'm sitting on a bunch of unpublished results that, to the best of my knowledge, aren't in the literature I've already thoroughly combed through, and yet I can't quite tell if they're worth the (nontrivial amount of) time to clean them up properly to be journal-worthy. Or at least arXiv-worthy, for that matter.

A stained glass window of a Latin square (en.wikipedia.org/wiki/Sir_Rona) will be removed from Cambridge U. (theguardian.com/education/2020) because it honors prominent eugenicist R. A. Fisher (en.wikipedia.org/wiki/Ronald_F).

The window visualizes a nice piece of mathematics, with a long history that surprisingly originates in Korea (predating Euler) but in context among windows celebrating Cambridge luminaries it could not be separated from Fisher's racist history, so it's sad but I think it's the right decision.

I guess I shouldn't be surprised that I get a bunch of Springer and Wiley ads for their books on other unaffiliated(!) sites just after I download a journal article from them. That being said, it's a little jarring to see next to webcomics I'm reading.

@JordiGH's recent poll on Japanese honorifics reminded me of another translation headache: pronouns. It's not always straightforward to deal with a character switching from e.g. γ€Œεƒ•γ€ to γ€ŒδΏΊγ€ in English.

People don't often realize that ivory towers can have feet of clay.
