The AI Revolution in Math Has Arrived | Quanta Magazine AI is being used to prove new results at a rapid pace. Mathematicians think this is just the beginning.

I'm taking away from this interesting article that AI might divorce *learning mathematics* from *doing mathematics* in a way that could make research less fun in the future

Could you enlighten me on the following? (I’m not an economist.) I understand that zombie companies staying afloat because of subsidies is bad, but why are dwindling profits bad per se (as the article seems to suggest)? Isn’t that the aim in competitive markets?

“Recent OECD analysis underscores the role of subsidies. Company-level analysis of Chinese industry by the 38-member organisation estimates that Chinese businesses are subsidised at between three and nine times the rate of their rich-world counterparts.” Between 3 and 9 times!

A very bad day for CDU/CSU-SPD governing coalition in Baden-Württemberg elections.

Merz' CDU loses to Greens after year-long polling lead.

SPD at disastrous low of 5.5%.

Expect pressure to increase on both Merz & SPD vice chancellor Klingbeil from within their own parties.

Don’t go after the rich to fix broken budgets It will not work, and is wrong in principle

What am I missing? Most proposals under discussion (e.g. the Californian tax or the French “Zucman” tax) target wealth inequality, not income inequality. Yet the article keeps criticising them based on steady or falling income inequality

yau says you are the schools expert in category theory. true? . 2 . is
there a topological equivalent to the power laws. ? 3 is there a geometric
derivation that is coherent ? 4, re language, as martin may have told you
i have been spending a great deal of time with Chomsky. i have been
trying to formalize the concept of signals ( images etc ) that are
coherent. . visual energy is first focused and then our vision
system eventually recognizes -separates , real world images from noise. a form
of a map? then arguably makes judgements based on similar ( distances from
already existing maps etc ). images. , meaning etc. . skype or call
might be helpful when and if you have time

query , is gravity merely a pseudo force. like centripetal ,
created by the central limit theorem. so that it is a consequence of the probabililty
distribution of matter in the universe . nothing more. . 2. in a truly
random probability space. if an event occurs for the first time,
does it increase the probability that it will happen again.

I think Jacob Lurie is more of an expert in category theory than I am, but I appreciate Yau's endorsement. I'm not sure I understand the questions in your first email. I'll have to ponder them. As for the others I'm not sure I know enough to think beyond the boiler plate answers. General Relativity tells us that gravity is an aspect of mass, so I wouldn't know how to think of it as a pseudo force. And "truly random" would be probably be taken to mean that the occurrence of an event does not increase the probability of it happening again. though I think Martin tells me that evolution, once it has solved a problem, is more likely to solve it again, so there may be a model of probability spaces that do have this property.

in math, he comes across as an annoying and ignorant crackpot, and could not have appeared otherwise to any knowledgeable person. for example he sent this garbage to hopkins, who somewhat disappointingly did humour him.
