Who has read this book? I’m trying to get back into maths. Last time I studied maths was when I was 16 and although a lot of the fundamentals are still there, a lot has been forgotten.

Anyone have advice for those getting back into maths?

Building ENS since forever.

Interested in identity, cryptography, climbing, health.

Understanding papers on cryptography or understanding technical posts by @vitalik.eth

I usually get stuck on the mathematical notation.

Secondly is to give me a better understanding of cryptography from a fundamental level

Any specific goals for picking up math? Is it just for mental alacrity? Also if you’re not talking about university-level math, then I think MBA (or equivalent) math can be good practice. Just filter for hard questions.

Free PDF my advisor used for his crypto course:
“Intro to Modern Cryptography”
Bellare & Rogaway, 2005
https://web.cs.ucdavis.edu/~rogaway/classes/227/spring05/book/main.pdf

To me, it was very readable (for such tough material).

Not sure if it's what you're looking for, I've been getting deeper into the maths lately and I started working my way through this yesterday.
