I'm very uncomfortable that someone with 204k followers and a responsibility for accurate dataviz should make the claim that "the UK death toll is accelerating", on the basis of 2 days' figures. https://t.co/d09tC7gLOk

Everyone knows that all circles are similar. But did you know that all parabolas are similar?

— Tamás Görbe (@TamasGorbe) April 3, 2020

The ratio of the red parabolic arc length and the blue focal parameter is

√2 + log(1+√2) = 2.29558...

for any parabola. This is the universal parabolic constant, the “π of parabolas”. pic.twitter.com/JntitYWd7q

Non-Euclidean visualizations usually show some regular constructions. Could we visualize the geometries themselves?

Let's distribute the snowballs randomly.

This is the Euclidean space. Looks a bit like space flight in some old video games. (1/10) pic.twitter.com/AHBqqjit26

Politics is back, baby! It's good again.

— Sonia (@yet_so_far) April 6, 2020

Full-throated defences of liberal values from liberal commentators can resume in the fullest confidence, now that the only political project that was in any danger of acting on their principles has been defeated. https://t.co/0TxmpGKOZf

Look at the Wuhan line on this new graph from @jburnmurdoch. The lockdown was introduced there on 23rd Jan – 69 days ago – which means this entire Wuhan curve has happened since then. It shows how long it can take to see the effect of control measures on the number of deaths. pic.twitter.com/MAsBIzFevj

Math textbooks are full of "fake-world applications": contrived scenarios that pretend to be about practical problems but would clearly never occur outside a math textbook. Already ancient Babylonian math is full of this. Social context helps explain why. https://t.co/MAkGPE3V9q

Daughter C (11 years old) just finished the whole set of Jenga Views puzzles. She was very proud of herself. (Puzzles can be found here https://t.co/9px8ObJiHt) #Homeschooling2020 😍 pic.twitter.com/TzqrAYGjdB

After an eight-year struggle, Shinichi Mochizuki has finally gotten his 600-page proof of the abc conjecture accepted in a peer-reviewed journal. But some experts are still unconvinced.

Some new comments by Scholze on abc, from here: https://t.co/83eriOY8Kq

— Daniel Litt (@littmath) April 6, 2020

Let me just add to this my own understanding — I’ve spent a fair amount of time with these papers and I see no evidence of new ideas whose strength would suffice to say anything exciting about abc. pic.twitter.com/m9jNbAco8B

I highly recommend the Bates LaTeX manual and @overleaf. After two (75 minute) classes, I had 100% of students producing LaTeX documents mostly without help. https://t.co/TlgYMEz6wk
