"While I try to do my part to destroy the environment, I try not to focus too much on individual responsibility. By pushing for broad policy changes, we can collectively do far more damage to the biosphere than any of us could on our own."

3blue1brown is a channel about animating math, in all senses of the word animate. If you're reading the bottom of a video description, I'm guessing you're more interested than the average viewer in lessons here. It would mean a lot to me if you chose to stay up to date on new ones, either by subscribing here on YouTube or otherwise following on whichever platform below you check most regularly.

I have a friend, Laura Siekman, who did her master thesis in mathematics of Escher's etchings π (technically the topic was "regular tilings of the hyperbolic plane", which is also the title of her thesis in Dutch, but that's just a mathematical description of a lot of Escher's work anyway). I remember she also kept trying to explain how interesting this picture was mathematically at the time she wrote it twenty years ago.

This video explains how ISO is very different to what most people imagine, and how you can use this knowledge to take less noisy photos!

TL;DW: in most cameras increasing the ISO setting works by pre-analog-to-digital voltage amplification, so using it should introduce less noise than digital brightening after the fact would. What this really means is that https://en.wikipedia.org/wiki/Exposing_to_the_right should also include increasing ISO if increasing aperture or exposure time won't cut it in the context of the picture you're taking.

I gotta hand it to the meteorologists, "the Quasi Geostrophic Omega Equation" is a top-tier name for an equation
Is this an AI psychosis joke?
