I did talk about this some time ago, but I found another person who shares similar gripes with the phrase "N times more/less than", and would rather just resort to "N times as much". So at least I know I'm not alone in this!
I know there are people who complain about π Day and τ Day only working in a Month/Day format
Some time ago I jokingly introduced a contender "sampi":
ϡ ≡ π/2 ≡ τ/4
So at least we could dedicate 15/7 as Sampi Day (ignoring the zero), celebrating the angle of orthogonality. And there are several notable properties of ϡ that (arguably) aren't as elegant with π or τ...
Maybe Mathstodon should have #SampiDay on 15th July?
"This #study will provide an in-depth understanding of the emotional roots of MA in primary and secondary #school children. The researchers will also characterize the relation of MA and general anxiety and links to mathematics performance, and develop robust MA questionnaires."
I'm unsure if this lecturer intentionally planned to hold his midterm test on #PiDay tomorrow 🤔
Probably gonna see π in Gaussian densities in some questions. Maybe even a question on estimating π via sampling?
"A pair of mathematicians has built on an obscure, 30-year-old mathematical theory to show that soap-filmlike minimal surfaces appear abundantly in a wide range of shapes."
Yeesh, that test just now is another reminder of why I loathe exams that disallow help sheets
Sure, you can test me on how well I can apply theorems/algorithms to questions, but I can't additionally memorize that stuff by heart at all
It feels like an unnecessary penalty for my rubbish memory rather than an actual test of my skills
Timothy Browning has discovered that
This settles all but one case of which two-digit numbers can be represented as a sum of three cubes. The remaining case is \(n=42\).

This particular thread on /r/math blew up: a Deputy is asking a question on behalf of an inmate who did a little personal investigation into some number theory
People really like the idea of the Deputy encouraging the inmate to dig deeper into the #maths, and keeping him mentally stimulated + educated while in prison
On a random note, I found this bottled iced #tea that I guess you pronounce as "Cha Pi" (茶\(\pi\)).
It's sweet red tea with rose + lychee (maybe a little too sweet). I've no idea what \(\pi\)) has got to do with it.
The more I study maths, the more it feels like the state of "being a mathematician" is an ideal but unattainable limit point, and one can only hope to enter a sufficiently small local neighbourhood around this point
I've heard anecdotes of people who've done PhDs in maths and *still* wouldn't feel comfortable enough calling themselves "mathematicians"
Still on the topic of integration, maths teacher blackpenredpen went through a 6-hour integral-solving marathon (100 integrals!)
Didn't know until now that MIT has an annual Integration Bee, which as you might guess is like a spelling bee but you're solving fiendish integrals instead of spelling words.
Also the winner - the Grand Integrator - gets a wizard hat 🧙♂️
"Katherine Johnson, the "human computer" whose work was depicted in the 2016 film "Hidden Figures," was recognized on Friday as the agency renamed a building after the pioneer.
The National Aeronautics and Space Administration redesignated a building that houses programs essential to safety on space missions in the 100-year old #mathematician's native West Virginia as the Katherine Johnson Independent Verification and Validation (IV&V) Facility."
