The video resolution is extremely low, with images glued as he moves away from what he wrote :-) The beauty of the early Internet.
No-Nonsense Quantum Field Theory by Jakob Schwichtenberg (2020) by Ciro Santilli 35 Updated +Created
This book really tries to recall basic things to ensure that the reader will be able to understand the more advanced ones.
Sometimes it goes a little bit overboard, like defining what a function does several times.
But Ciro Santilli really prefers it when authors error on the side of obvious.
This is very widely used in courses as of 2020, it became kind of the default book.
Unfortunately, this approach bores Ciro Santilli to death. Or perhaps is too just advanced for him to appreciate. Either of those.
800+ pages.

RSA (cryptosystem) by Ciro Santilli 35 Updated +Created
Based on the fact that we don't have a P algorithm for integer factorization as of 2020. But nor proof that one does not exist!
The private key is made of two randomly generated prime numbers: and . How such large primes are found: how large primes are found for RSA.
The public key is made of:
  • n = p*q
  • a randomly chosen integer exponent between 1 and e_max = lcm(p -1, q -1), where lcm is the Least common multiple
Given a plaintext message m, the encrypted ciphertext version is:
c = m^e mod n
This operation is called modular exponentiation can be calculated efficiently with the Extended Euclidean algorithm.
The inverse operation of finding the private m from the public c, e and is however believed to be a hard problem without knowing the factors of n.
However, if we know the private p and q, we can solve the problem. As follows.
First we calculate the modular multiplicative inverse. TODO continue.
Position representation by Ciro Santilli 35 Updated +Created
A way to write the wavefunction such that the position operator is:i.e., a function that takes the wavefunction as input, and outputs another function:
If you believe that mathematicians took care of continuous spectrum for us and that everything just works, the most concrete and direct thing that this representation tells us is that:
the probability of finding a particle between and at time
equals:
Rayleigh-Jeans law by Ciro Santilli 35 Updated +Created
Derived from classical first principles, matches Planck's law for low frequencies, but diverges at higher frequencies.

Transcription unit by Ciro Santilli 35 Updated +Created
A sequence of mRNA that can actually be transcribed.
Multiple different transcription units can be produced by a single operon, see: operon vs transcription unit.

P versus NP problem by Ciro Santilli 35 Updated +Created
Interesting because of the Cook-Levin theorem: if only a single NP-complete problem were in P, then all NP-complete problems would also be P!
We all know the answer for this: either false or independent.
