"Private equity firms have purchased life insurers and loaded them with risky debt, exposing policyholders and the public to losses and raising the threat of financial contagion."

Two and a half stones!

It must be more with a keystone. One brick lies across the middle and rests only on its two ends, on the tips of two cantilevers. It adds a full brick length to the span, while each side carries just half a brick’s weight at its tip. For example like this, for 2.5 brick lengths.

The best you can do with 4 bricks is 1.16789... (see arxiv.org/html/0710.2357) But what about a bridge of 8 stones? . Two optimal 4-brick stacks back to back, that is two times 1.16789?

DAG people rejoice! The link between understanding and problems is just collider bias from conditioning on solutions.

I disagree with Terence Tao's view of mathematics, which he articulated in a talk yesterday at Caltech (see slide below). Applied math problems are not disjoint from pure math problems. This is not a minor matter. So no, this is not a "more accurate model". It's embarrassing.

OpenAI issued PR statements saying they were interested in providing tools, not solving problems, then plowed millions of dollars of compute into solving problems. It is worth considering whether this has negative first order effects.

*Mathematicians did not ask for this work to be done" WTF?!! Since when was math something that was only done at the request of professional mathematicians?!! Mathematicians don't own mathematics! This is crazy!!

A lot of people—me included—do not enjoy reading LLM outputs. There’s an alternative! Personally I have always been very bad at reading mathematics. But you don’t have to read it by reading it, if that makes sense. Rather, you think in its general vicinity.

I once had a conversation with Akshay Venkatesh where he was explaining some result to me and I commented “wow, you read that [difficult] paper?” And he replied “well, I imagined I read it.” Made a big impression on me.

But the spider web itself is implemented using a small solver of Hooke's law that iteratively moves each free node in the direction of its net force. That is why adding a radius visibly shifts the hub and deforms the frame rather than simply drawing a new straight segment.
