Physicist and science communicator. Writes Backreaction and makes videos explaining new physics and astronomy results, frequently to argue that the headline about them overstates the case.
It's a bad idea. If you dictate scientists just what to work on, you will get a low return on investment. The current science funding schemes ALREADY have this problem: pour money into some specific program, see scientists produce something that fits into the program to get the money --> topic is overcrowded with incremental and nonsense research that mostly leads nowhere. It's inefficient for the same reason planned economies are inefficient. Scientists need MORE freedom to do what they want, not less. Quoting @NewsfromScience The National Science Foundation (NSF) has issued a 10-page memo signaling a retreat from its traditional role of giving grants to individual researchers to pursue their best ideas and to train the next generation of scientists. Instead, the memo makes clear, NSF will devote the bulk of its resource… Related

Stimulating piece on Scottish education in @asteriskmgzn: https://t.co/jyTk8uTT1J. I suspect that discussions of canon, culture, and shared context to return to the fore in the coming years, as many skills, narrowly-construed, are ceded to AI, and as some of the excesses of de-Arnoldization, and the processes that Arendt described in her writing on education, start to recede. I’m curious on the causal linkage between PISA scores and the reforms he describes. It feels like a very exciting time to be a theorist of education, and I assume that the best work will come from surprising places. Related

A really lovely GRID VIEW is coming to Basecamp 5 shortly. We had a grid view in 4, but it wasn't any good and I didn't want to drag it into 5. Had we done that, we'd have called it done and never revisited. By intentionally leaving it out, we allowed pressure to build to bring it back. And with no legacy to battle or revamp, we were able to return to the drawing board and make something so much better, from scratch. Coming to a Basecamp near you. Soon. Related

I've been surprised to find that sometime in past six months or year, ChatGPT has generally started returning better results than Google for me. OpenAI probably has fewer employees than Google Search alone, and what fraction of OAI works on search? On the order of 1%? Arguably an unfair comparison because ChatGPT takes 20x longer to return a result, but Google doesn't have a "20x slower but don't return https://danluu.com/seo-spam/ knob" OpenAI Google Related

A Monday morning question for you: I'm not usually awake from 5am to 6am, but when I am I tend to enjoy it. Start the day slow. Watch the sunrise. Get a few things done before everyone else wakes up. Meanwhile, I am often awake from 10pm to 11pm and I find that I tend to use it poorly. Passively watching TV or scrolling on a screen. Late-night snacking. Generally focusing on things that are fairly unimportant. Trading the last hour of the night for the first hour in the morning would be a pretty high-value trade for me. Which hours of your day tend to return the most value and which ones tend… Related

RE: https://mastodon.social/@refactoredd/117157266100987313 I may someday return to it, but I have shelved it for now. I just don't use an iPad enough. The worst part of developing the app was having to carry an iPad with me. 😬 Every time I try to work an iPad into my computing life, it doesn't stick for very long. It feels like computing with mittens on. Nearly everything I frequently do with my computer or phone is less capable, more cumbersome, or outright impossible on an iPad. And the iPad's strengths are generally things I rarely or never do. Related

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who

Nobody here wrote their own korrents. They are compiled from public
