Spin number of a field by Ciro Santilli 35 Updated +Created
Physics from Symmetry by Jakob Schwichtenberg (2015) chapter 3.9 "Elementary particles" has an amazing summary of the preceding chapters the spin value has a relation to the representations of the Lorentz group, which encodes the spacetime symmetry that each particle observes. These symmetries can be characterized by small integer numbers:
As usual, we don't know why there aren't elementary particles with other spins, as we could construct them.

Basically a synonym for doing a large chunk of de novo DNA synthesis.
Schrödinger equation for a free one dimensional particle by Ciro Santilli 35 Updated +Created
Then, for each energy , from the discussion at Section "Solving the Schrodinger equation with the time-independent Schrödinger equation", the solution is:
Therefore, we see that the solution is made up of infinitely many plane wave functions.
The correlation between software engineers and Buddhism by Ciro Santilli 35 Updated +Created
Ciro Santilli believes that there is a positive correlation between being a software engineer and liking Buddhist-like things.
Maybe it is linked to minimalism and DRY, which software engineers value so greatly.
Even Ciro had to try an unoriginal Buddhist joke intro in one of this Stack Overflow answers.
Ciro also feels that his "minimal reproducible example" scientific language/concept learning method obsession of breaking things into tiny sub-problems has a strong link with Koans.
Some notable Buddhism/programmer examples:
Another thing that points the correlation out is the existence of wattsalan.github.io/ on a github.io about Alan Watts.
Jim Simons by Ciro Santilli 35 Updated +Created
Ciro Santilli's wife, who was frustrated with academia at some point, admires the fact that Simons managed to make infinite money, and then invested back in actual science, e.g. through the Simons Foundation.

Bitcoin whitepaper by Ciro Santilli 35 Updated +Created
Released by Satoshi Nakamoto on the early mailing list discussions where Bitcoin was announced.
More conveniently available on bitcoin.org: bitcoin.org/bitcoin.pdf nowadays, except when it was down for a few years due to our master Craig Steven Wright.

Man shall not live by bread alone by Ciro Santilli 35 Updated +Created
Gospel of Matthew 4:4:
Man shall not live by bread alone, but by every word that proceeds out of the mouth of God
Ciro Santilli's mother loves that one. Even though she was constantly worried that if Ciro had studied physics he would be poor and starve, a factor which led him to study engineering instead, one of the greatest mistakes of his life. don't be a pussy.

where:
Note that this is the sum of the:
  • Dirac Lagrangian, which only describes the "inertia of bodies" part of the equation
  • the electromagnetic interaction term , which describes term describes forces
Note that the relationship between and is not explicit. However, if we knew what type of particle we were talking about, e.g. electron, then the knowledge of psi would also give the charge distribution and therefore
