Desmos Studio is hiring! 🎉🎉🎉 We are looking for people to join us in our mission to help everyone learn math, love math, and grow with math. Learn more about our openings for a UI / Visual Designer and a Community Manager here: desmos.rippling-ats.com/
We learned today that WebKit/Safari has special behavior for desmos.com hard coded in. Guess we’re in the big leagues!

In case I have any followers that work on Webkit: there's a bug that shipped w/ Safari 16 that affects some very basic uses of canvas. I don't see a great way to work around this systematically.

Holy hell, it actually happened: California just eliminated minimum parking requirements for new housing projects within a half mile of public transit stops *statewide*!
A truly incredible day for housing and climate policy in the world's 5th largest economy!

Accessibility is not just about the end result, but about the experience. If I can get it done, but it’s 10X more frustrating and takes 10X longer for me as a blind user, it’s not truly accessible. Ultimately, #a11y is about equity of opportunity as well as experience.

If you were in any doubt about the idea that girls avoid physics because they “don’t like hard maths” you should read this exceptional response.

I’ve always wished I had the courage to use this, from Lev Landau, “Excuse the delay, due to my extreme antipathy to the epistolary art.”

Debate is not much of a truth-seeking activity. It’s a parody of truth-seeking in which uncertainty and ambiguity are perceived liabilities. To advocate for a text means omitting whatever careful qualifications its author has made, delivering it as its own reductio ad absurdum.

Early on in my career I sometimes used exercises where I asked students to adopt opposed positions from texts and debate each other. It usually didn't work well.
Now I use exercises where I ask students to imagine how they would teach texts to other people. It works well.

It was a fascinating challenge explaining Mirzakhani's math in this sensitive and touching documentary about her extraordinary life. If you haven't seen it yet, check your tv listings!

It's bewildering that there is so little public funding available to develop and maintain infrastructure that is useful to many researchers compared to the funding that is available to individual researchers to do their own research.
New blog post: fredrikj.net/blog/2022/02/lo… I discuss the current state and long-term development plans (features, maintenance, funding) of some free software projects that I help maintain or depend on (mpmath, FLINT, Arb, Calcium, Fungrim, MPFR, GMP).

∞ is not a Real number, but some explanations for why not claim too much.
“∞ is not real because ∞-∞ is indeterminate,” but 0 is Real even though 0/0 is indeterminate.
“∞ can only be approached as a limit”, but √2 is also only approached as a limit (of rationals).
It’s hard to correctly say why ∞ is not real without either bringing up the definition of a field (axiomatic approach), or the concept of convergence of sequences (constructive approach).
