Not a physicist but this echoes my feelings when people talk about time as an emergent phenomenon.

- measurablefunc 1y agoI'm not a physicist either but this stuff isn't magic. Most of the mathematics used by physicists isn't complicated if you've managed to get past calculus.
- GOD_Over_Djinn 1y agoAt this point, numerous exotic mathematical tools from Langlands program, Lie algebras, algebraic geometry and topology have been used in physics. I do agree that you can go quite far with calculus, linear algebra, and probability. But I do think that you overstate the case.
- measurablefunc 1y agoAlgebraic geometry isn't any more complicated than multi-variable calculus. It's certainly more abstract but you get used to it after a while. Schemes¹ are not difficult to learn if you know basic commutative algebra & topology. If you don't know basic commutative algebra then you'll have a tougher time but it's again something that can be learned w/ enough practice & patience. ¹https://webhomes.maths.ed.ac.uk/~v1ranick/papers/eisenbudharris.pdf https://webhomes.maths.ed.ac.uk/~v1ranick/papers/eisenbudhar...
