I’m not sure I understand what you are saying here: do you mean that most of the light from the sun is in this range, so that’s why life evolved to use it?

Sometimes when building a minimal reprex for a bug, you discover that you were the bug all along. I assume this is what Kafka was on about.

This is not what I expect from the MAA. I agree it sounds like article was written by an LLM

The reason I prefer this is that it’s feels more natural, not a random collection of rules. Symmetry, ability to undo a move, ability to compose moves, are all very natural things to want to have/study. But the set-with-operation def seems hard to justify vs semi group or monoid—it feels arbitrary

Tyler Jarvis @tylerjarvis.bsky.social · 15/01/2025
I’ve long felt that the set-with-binary-operation definition is the wrong way to define a group. I much prefer to say it is a nonempty set of symmetries (bijective functions of some set to itself) that is closed under compositions and inverses. Associativity and the identity come for free.

When I was a young man there were whispered rumors among the elders that they could remember their own elders talking about a time when getting grants had been a means for doing science, rather than vice versa.

This is crazy. It's morally wrong, socially irresponsible, technically stupid, financially dangerous (does that tiny disclaimer saying "don't trust this!" in a tiny font going to hold up in court?). What is up at Google, have they truly given the reins of the company to an unfathomable idiot?

I genuinely cannot believe Google is now showing Gemini-generated medical snippets including *drug summaries and medical advice* to treatserious health conditions. I checked. It does. With barely a tiny disclaimer about GenAI. How can a (formerly?) trusted company be so incredibly reckless?

Hard disagree. It looks better than any other system out there, by orders of magnitude. Making math easily readable takes work, just like explaining math clearly takes work. Plus it's easy to make a macro--please just don't inflict MSWord upon us.

The world is a LOT better for children than it was 50 years ago. ourworldindata.org/child-mortal...
Plot of child mortality (deaths before the age of 5) in 1970 and 2022  for the US, the EU, China, Africa as a whole, and many individual countries.  In all cases child mortality has significantly decreased. DR Congo went from 24.9% in 1970 to 7.6% in 2022;  China from 11.3% to 0.7%; the US from 2.3% down to 0.6%.  Australia and the EU are currently lowest at 0.4%. Source: Our world in data https://ourworldindata.org/child-mortality-global-goal

The math benchmarks I want: 1. OopsBench: given a faulty proof with numbered steps, which step contains an unfixable logical flaw? 2. DunnoMath: half the problems are taken from FrontierMath, half are almost certainly unsolvable. Major points off for guessing an answer to an unsolvable problem.

New phenomenon where students show up with a chunk of ChatGPT code and say "it doesn't work" and I say, "well what did you try?" and they explain the different things they asked ChatGPT. It's pretty worrying

Should be the math em, because mu is intended to be used in math mode
000
Tyler Jarvis @tylerjarvis.bsky.social · 12/12/2024
As a general strategy, you want to use em as your main unit for horizontal lengths in text, and use ex for vertical lengths in text (mu for horizontal lengths in math mode) Other units do not scale when the font size changes (which needs to happen much more often than you think it will)
020
Tyler Jarvis @tylerjarvis.bsky.social · 12/12/2024
Note that’s 1/18 of a math mode em. I think it’s because math equations often need finer adjustments than text does so the default unit in math mode (mu) is smaller than for text (em)
