I Set A Trap To Catch My Students Cheating With AI. The Results Were Shocking. "Students are not just undermining their ability to learn, but to someday lead."

To “my students and to anyone who might listen, I say: Don’t surrender to AI your ability to read, write and think when others once risked their lives and died for the freedom to do so.”

How Soon Will the Seas Rise? | Quanta Magazine The uniquely vulnerable West Antarctic Ice Sheet holds enough water to raise global sea levels by 5 meters. But when that will happen — and how fast — is anything but settled.

Ice dam at Alaska’s Mendenhall Glacier releases floodwater toward downstream homes A huge basin of rainwater and snowmelt dammed by Alaska’s Mendenhall Glacier has started to release, sending a potentially record surge of flooding toward parts of Juneau in what has become an annual concern for residents.

A huge basin of rainwater and snowmelt dammed by Alaska’s Mendenhall Glacier has started to release, and officials on Tuesday urged residents in some parts of Juneau to evacuate ahead of what could be a record surge of floodwater downstream.

5-panel comic. (1) [teacher with long hair next to whiteboard] TEACHER: I’m supposed to give you the tools to do good science. (2) [teacher addressing students] But what *are* those tools? Methodology is hard and there are so many ways to get incorrect results. What is the magic ingredient that makes for good science? (3) TEACHER: To figure it out, I ran a regression with all the factors people say are important: [embedded list in sub-panel, cut off at end] Outcome variable: correct scientific results. Predictors: collaboration; skepticism of others’ claims; questioning your own beliefs; trying to falsify hypotheses; checking citations; statistical rigor; blinded analysis; financial disclosure; open data (4) TEACHER: The regression says two ingredients are the most crucial: 1) genuine curiosity about the answer to a question, and 2) ammonium hydroxide. (5) STUDENT: Wait, why did *ammonia* score so high? How did it even get on the list? LONG HAIR: ...And now you’re doing good science!

America’s infatuation with boy geniuses and ‘Great Men’ is ruining us We’re obsessed with narratives about powerful men and how they got that way. But our mania for founder myths obscures an ideology of inequality

Excellent essay about the power of the myth and its danger. Origin stories impact many socio-economic trajectories from personal statements in graduate school applications to personal narratives to pursuade investors. Aspirational stories win, true or not.
