I'm almost in awe at Rowling's confidence in herself as a writer that she would set for herself the task of explaining why the heroes of her story didn't stop the Holocaust. https://t.co/f7ukd2CPz5

高校数学の教科書には、「〜〜を数学的帰納法で証明せよ」という問題がある。
解答例「n=1のときは明らかに成り立つ。n=kで成り立つと仮定してn=k+1で成り立たないとすると、帰納法で証明できないので、問題に反して困る。よってn=k+1でも成り立つ。帰納法により任意のnで成立する。」

I was on a train for the first time in ages last Sunday.
It struck me that, in the same way we have a quiet carriage, couldn’t we have carriages for people who want to wear masks and carriages for people who don’t?

100,000 kids off school with confirmed or suspected covid.

What happened to children’s education bring a top priority.

This is an abject failure of policy.

Our children deserve better.https://t.co/7dI36Zuo9X

CHARTS OF LARGE CARDINALS
A Thread

The ladder of large cardinals is ubiquitous in modern work in set theory, with the consistency strength of many statements being calibrated by its rungs. Here I collect published charts of fragments of the hierarchy.

We are creating a Data Science + Mathematics degree/major and I am pleased that it requires two ethics courses.

It absolutely beggars belief that some U.K. scientists are still gaslighting us with “schools just reflect community transmission” BS.

Rates in older people are typically going down, but in school-age children they are rising.

How do you square that? pic.twitter.com/FYKcpy8B5r

There are simple things we could have been doing to prevent kids catching covid in schools.

Masks, isolation, efficient contact tracing, bubbles, ventilation, vaccination.

Where are the CO2 monitors that were promised? Not in my kids’ school for sure.

When we teach calculus, we *at once* introduce (at least) 5 new concepts (limits, tangent lines/slopes, derivatives, area, integrals), all intertwined together. There's no reason for this! Most of these ideas can be introduced *much* earlier, one at a time. Here's an attempt at.. pic.twitter.com/mWed3rS9sn

Know any new(ish) faculty in the math. sciences who want great professional development and a supportive community? #MAAProjectNExT applications are open!

Just saying “we should treat covid like any other respiratory virus” won’t magically make covid just like any other respiratory virus.

Some videogames pretend to be spherical, but they are not! They are just the old flat plane but with stereographic projection. Easy to tell because we cannot have a hex or square grid on a sphere (a beautiful math fact). (1/5) pic.twitter.com/xtDGDJXkko

Question: Why do we attribute calculus to Newton and Leibniz? For instance the fundamental theorem of calculus was already known to Isaac Barrow (Newton's teacher). Other concepts date back even earlier, e.g. in ancient Greece and India there were calculus concepts already.

"Mathematics is the ultimate language! It is cold and concrete and precise!"

Meanwhile mathematicians: "If we assume this conjecture we don't know how to prove, we then see that this is greater than or equal to this, up to some fudge factors. The proof is easy to see."
