Technique to solve partial differential equations
Naturally leads to the Fourier series, see: solving partial differential equations with the Fourier series, and to other analogous expansions:
One notable application is the solution of the Schrödinger equation via the time-independent Schrödinger equation.

- buy some at a cryptocurrency exchange. This is the only viable way of obtaining crypto nowadays, since basically all cryptocurrencies require specialized hardware to mine.
- send it to a self hosted Bitcoin wallet without a full node, e.g. Electrum
- then send something out of the wallet back to the exchange wallet!
- convert the crypto back to cash

When we have a symmetric matrix, a change of basis keeps symmetry iff it is done by an orthogonal matrix, in which case:

Quite good, Ciro Santilli played this a lot in 2021/2022, his user ID: ofo5fNy7wRNC1Cw94YVB4KMOW5f2.
The physics not as good as the original Mario Kart 64, and it is notably missing jump gliding, and generally not as sharp! But it is really not bad.
Some of the weapons were too useless that you are just better firing them straight away at wall immediately to get something better, they could have a little better balancing there. I'm talking about you gatling that takes 10 seconds to finish firing, and does not kill enemies immediately. You are better off just firing that gun immediately when you get it to be able to get another gun ASAP. They seem to have done some balancing there however.
It had no chat option, but in a way it was cool to be forced to communicate non-verbally with people whose usernames you got familiar with. Funny you can love people like that, without ever talking to them. The best way of doing so being tea-bagging by going back and forth on a player after winning.
Performance was sometimes a problem. When Ciro tried it again on December 2022, it was unplayable due to the impossibly large lag. Things were much better again in 2023 however it seems.

AGI research has become a taboo in the early 21st century Updated 2025-07-16
Due to the failures of earlier generations, which believed that would quickly achieve AGI, leading to the AI winters, 21st researchers have been very afraid of even trying it, rather going only for smaller subste problems like better neural network designs, at the risk of being considered a crank.
While there is fundamental value in such subset problems, the general view to the final goal is also very important, we will likely never reach AI without it.
This is voiced for example in Superintelligence by Nick Bostrom (2014) section "Opinions about the future of machine intelligence" which in turn quotes Nils Nilsson:
There may, however, be a residual cultural effect on the AI community of its earlier history that makes many mainstream researchers reluctant to align themselves with over-grand ambition. Thus Nils Nilsson, one of the old-timers in the field, complains that his present-day colleagues lack the boldness of spirit that propelled the pioneers of his own generation:Nilsson’s sentiment has been echoed by several others of the founders, including Marvin Minsky, John McCarthy, and Patrick Winston.Concern for "respectability" has had, I think, a stultifying effect on some AI researchers. I hear them saying things like, "AI used to be criticized for its flossiness. Now that we have made solid progress, let us not risk losing our respectability." One result of this conservatism has been increased concentration on "weak AI" - the variety devoted to providing aids to human
thought - and away from "strong AI" - the variety that attempts to mechanize human-level intelligence
