Tau Day @TauDay
6/28 is #TauDay, a celebration of the true circle constant. Founded with The Tau Manifesto by @mhartl, which proposed using the name τ (tau) for C/r = 6.28… tauday.com The Platonic Realm Joined June 2010-

Looks like DALL-E knows the score. 🤓 #PiDay #HalfTauDay
Looks like DALL-E knows the score. 🤓 #PiDay #HalfTauDay
I was curious how DALL-E might render a pi creature, and its true preferences for tau were revealed. And on today of all days! (Then again, maybe it's on me for the typo)
Happy #HalfTauDay, everyone! #PiDay #PiDay2024 michaelhartl.com/happy-half-tau…
Author Sheldon Axler was kind enough to give me early access to the fourth edition of Linear Algebra Done Right (40% off until February 22), and in return for my feedback he gave me this snazzy hardcover print edition. Much thanks to @AxlerLinear!

Terry Tao and I are pleased to announce the "Prime Number Theorem and Beyond" project, which you can find here: github.com/AlexKontorovic… with blueprint here: alexkontorovich.github.io/PrimeNumberThe… and dedicated stream in the Leanprover Zulip chat. The initial goal is to get the Prime Number…
@keenanisalive The distinction between balls & spheres gets a careful discussion in Section 5 of The Tau Manifesto. As a bonus, we get beautifully succinct formulas for the corresponding volumes and surface areas. (Here λ = τ/4 = 1.57… is the measure of a right angle.) tauday.com/tau-manifesto#…
If you’ve ever taught (or even learned) fractions, you might have seen tempting but erroneous manipulations like a/b + c/d = (a + c)/(b + d). Interestingly, though, the superficially similar relation a/b = c/d = (a + c)/(b + d) is actually correct!
I’ve published a status update on my math learning project. Enjoy! michaelhartl.com/status-update-…
Yesterday I talked about the Euler line with a friend who has a Ph.D. in mathematics from Caltech. He confirmed that he had never heard of it, either, and indeed was surprised to learn that a triangle’s orthocenter, centroid, and circumcenter are collinear.

Author @AxlerLinear was kind enough to give me early access to the 4th edition of Linear Algebra Done Right, so I can confirm that it is a masterpiece of mathematical exposition—highly recommended to anyone looking for an advanced, proof-based treatment of this essential subject.

I am delighted to announce publication of the 4th edition of Linear Algebra Done Right as an Open Access book. The electronic version is legally free to the world at linear.axler.net. That website also has links to pre-order the print version of the book. #linearalgebra

@MathMatize The Cantor–Schröder–Bernstein theorem, which states that, if two cardinalities satisfy |A| ≤ |B| & |B| ≤ |A|, then |A| = |B|. It may seem obvious, but Cantor was unable to prove it. He published the result in 1887, but had to wait until 1898 for Schröder’s & Bernstein’s proofs.

Happy Circle Day! Sigma (σ) looks like a circle whose circumference (C) is being measured with its radius (R). σ ≡ C / R = 2π = 6.28... @mhartl & @TauDay use tau (τ=σ): tauday.com Happy 52nd Birthday to @elonmusk!
HAPPY TAU DAY! T = C/r 6.28
Happy #TauDay everyone! Please enjoy the #TauDay2023 State of the Tau newsletter: tauday.com/state-of-the-t…
You all know that for any circle, c/d = π. But did you know that c/r = τ (Tau)? So essentially, τ = 2π. But as ancient as these letters are, Tau was chosen to represent the circle constant τ = 2π #onthisday - in 2010! On #TauDay... 1/2
My reading for the next few weeks.
@WKCosmo How do you know if someone is a math nerd? They celebrate Pi Day on March 14th and Tau Day on June 28th.
Happy Half Tau Day! (Remember to add "Buy Two Pies" on your calendar for June 28.) tauday.com/tau-manifesto
