pi = 3.14159... while 22/7 = 3.14285... so 22/7 is bigger. But here's a cute proof that 22/7 is bigger.

The integral that gives 22/7 - pi is surprisingly elegant, and it's clearly positive since you're integrating a positive function. pic.twitter.com/Dj2HJMYRJD
The difference between the exponentials exp(A) - exp(B) of matrices A and B can be expressed concisely in terms of an integration involving their difference A - B. (The proof is one line!) #calculus #math pic.twitter.com/WXADR4N4By

The gulf between words written on the spines of non-curriculum math books and curriculum math books speaks a painful volume to the almost unbridgeable chasm that exists between the freedom of mathematics and its incarceration as a "performing seal"... pic.twitter.com/qLjWLNA1JQ

James Watson (as in Crick &) has been stripped of certain honours at a NY lab thx to comments about race and intelligence. If you're worried that he is simply stating uncomfortable truths, this great blog post should reassure you.https://t.co/2KOJGwgIC5

Why is math such an important issues for social justice. @profnicolej says 1) it is weaponized against blacks 2) black children are disproportionately tracked into the lowest math, and #data4blacklives 1/2

The head of Harvard's astronomy department thinks that Oumuamua - the mysterious object that shot through our solar system in 2017- could be an alien probe. In this interview he explains why. I'd say it's a long shot, but very interesting.https://t.co/0ffLDhmAto

Oh dear, yet another mathematical giant has left us (after Peter Swinnerton-Dyer, Elias Stein and Jean Bourgain). He was also a former master of Trinity College Cambridge, and extraordinarily energetic right into his late 80s. https://t.co/JrAVBkGLdG

If we try to extend the complex numbers the way we extended the reals to get the complexes, by adding more square roots of -1, we get the quaternions Q. The resulting differential calculus of quaternion functions fails some basic expectations. #algebra #math pic.twitter.com/ho4TRNL0jC

Sorry to confirm that Sir Michael Atiyah has died today. It is hard to believe that such a force of nature, life, and mathematical creativity is gone. RIP. https://t.co/AHCdS9EfdG

Dogs on leashes dragging their owners. Surely, this has nothing to do with maths! Well, if they are running along a line perpendicular to the initial direction of the leash, the owners will be dragged along a curve called tractrix.🐶 [Wiki https://t.co/vsVHvk2JyB] #50FamousCurves pic.twitter.com/PUZr63X7hF

Ursula K. Le Guin vs. academia. "I have never in my life been so honored as I was on those frigid Rochester evenings when Ursula K. Le Guin told a department chair that if he wanted her attention, he’d have to ask permission from the freshman" https://t.co/hJJ8dkvio1

En Dolores, un cabo de policía junto con otra persona provocó la muerte de un sospechoso de hurto, que era inocente. Hay medios que titularon “justicia por mano propia”.

No es “justicia”.
