Amongst the many petition tracking sites (which help to avoid the actual site crashing), this is quite a good one, as it puts the constituencies in order of how many signatures they have. Proud to see that Cambridge is third. https://t.co/59rVx02Weo #RevokeArt50Now

A fractal impossible object, packed with impossibility at multiple scales!

— John Carlos Baez (@johncarlosbaez) March 23, 2019

Nidhal Selmi drew this. It's a blend of the Sierpinski triangle, a famous fractal, and the Penrose tribar, a famous "impossible object".

Let me explain how it's connected to sheaf cohomology.

OMG this makes me so happy!!!! Karen is not only a great mathematician, but a wonderful mentor/sponsor. She is one of the main reasons grad school was survivable and even sometimes enjoyable for me and other women in the program. So well deserved. https://t.co/TsxME0Z7G7

The well-known #Gaussian integral over the reals extends naturally to positive matrices. (Can it be extended beyond that?) #funtime #calculus #algebra #math pic.twitter.com/SA7SL50EaH

La matemática Karen Keskulla Uhlenbeck (1942) ha ganado el Premio Abel por sus aportaciones en análisis, geometría y física matemática. Es la primera mujer en conseguirlo. ¡Enhorabuena!

Homophobia cannot be allowed to influence education. Queer kids have the right to grow up knowing they are loved unconditionally.

This feels like a creeping return to Section 28

Vectors in Minkowski space can be nicely represented using 2x2 matrices. In this representation, Lorentz transformations can be expressed as matrices L in SL(2,C) that transform a 2x2 matrix/vector V to LVL*. #algebra #physics #math pic.twitter.com/XgzVo3QTaw

A cube whizzes past at nearly the speed of light, c. What do you see? Lorentz contraction squashes the cube. But you *see* it as rotated and bent, since light from different parts of the cube take different amounts of time to reach you - and it's moved a lot by then!
