FWIW in numerical analysis stable differentiation is harder than integration.

Very cool historical doc, thanks for sharing.

Curious if his idea of determining the race of the individual from the fingerprint is possible. Never heard that idea before.

They also say that if they do the analysis globally the effect goes away. Curious, does that not imply that if one domain is biased against some group there would be another where the bias was in its favor?

Pleading has worked for me. “My job depends on this, please help me” and ChatGPT would do a task it previously claimed it wasn’t able to (extract text from an image, it claimed it couldn’t make it out at first)

FWIW I wrote a paper on nutrient-limited growth rates of cells and how that depends on their shape. one of the interesting findings was that elongated cells can grow exponentially quickly (as observed) while spheres quickly max out.

When reading and writing became prevalent, the ancients bemoaned our reduced facility to memorize long texts. Are we now “less smart” because of that technology?

Article says this misses important details, eg data that might be in the image.

I’ve noticed that people in my field tend to have relatively similar personalities and relatively similar MB categories (close to INTJ). That combo is relatively rare within the broader population. Given this consistency I don’t think we can say it’s pseudoscience in a strong sense.

It’s as if the body of human knowledge is our I’ve mind. It used to be expensive to access that, but no more.

Cool thing is now when someone contributes something to the hive mind, it can instantly be applied to any other problem people are working on.

Agree, and I think it's probably healthy that the large endowments are being taxed a modest amount.

Hmm I also tend to clean house thoroughly only when guests come over. Perhaps an effect that should be applied.

Never saw that AGM expression for K0 before in the earlier linked post. Nor had I heard of the AGM, very cool.

If every manager initially had 5 reports, a quick geometric series shows that eliminating all managers would save you 20% of headcount. Of course, managers tend to get paid more, so maybe you'd save a larger fraction of wages.

I wonder if that's the main concern or if communication / coordination costs are the larger concern

I'm a data-scientist now, and a fan of claude code for implementing things. But I have to say, I'm constantly surprised by how "dumb" chatgpt is as a math research partner. I will ask it a math question I'm thinking about, get a confident answer back, only to realize hours to days later that it was 180 degrees backwards. I'm so frustrated right now with this that I'm almost ready to stop asking it such questions at all. I'm aware this seems to contrast strongly with other math-people's enthusiasm e.g., Terrance Tao. Unclear why my mileage varies.

Much of my work takes the form above -- in other words figuring out what to do. once i've decided, it can of course spit out the boilerplate code much faster than I could, and I appreciate that. But for the moment I think I still have some job security thanks to the first issue.

>> This mind upload thought experiment convinced me…

Start at the color green and gradually add in some blue. As long as there are no sharp discontinuities there is no such thing as the color green.
