However, many, many, many terrible horrors come with it:
Animal-in-the-loop Updated 2025-07-16
Ciro Santilli invented this term, it refers to mechanisms in which you put an animal in a virtual world that the animal can control, and where you can measure the animal's outputs.
Andromeda Galaxy Updated 2025-07-16
First proper nearest galaxy to the Milky Way. Everything in the middle in the Local group is either a satellite of the Milky Way or Andromeda.
Many Andromeda satellite galaxies are simply numbered Andromeda II, Andromeda III and so on.
As described on Wikipedia, the observational history of Andromeda is fascinating. Little by little, people noticed that it had a different nature to many other objects observed on the sky, and the hypothesis that there are other galaxies like ours grew in force.
Part of our fascination with Andromeda is due to how similar in size and shape and close it is to the Milky Way.
It is clearly the only thing so large and so close.
Andromeda is, without a doubt, our sister galaxy.
One can't help but wonder if there is some alien looking back at us when we are looking at them through our telescope.
Andromeda is also the furthest object from Earth that can be seen with the naked eye.[ref] Not surprising, as it literally shines with the strength of a trillion suns!

He's also curious about quantum computing: quantum.country/ like Ciro Santilli. Some crazy overlaps we get.

UniProt human: www.uniprot.org/uniprot/Q9BYF1 It is interesting to see in the Mutagenesis how many known mutations can increase or decrease SARS-CoV-2 S protein binding affinity.

He's good. Sometimes a bit repetitive, but generally pretty good.
Only the "original" videos matter. After those it became crap.

Angular momentum operator Updated 2025-07-16
Basically the operators are just analogous to the classical ones e.g. the classical:
becomes:
Besides the angular momentum in each direction, we also have the total angular momentum:
Then you have to understand what each one of those does to the each atomic orbital:
There is an uncertainty principle between the x, y and z angular momentums, we can only measure one of them with certainty at a time. Video 1. "Quantum Mechanics 7a - Angular Momentum I by ViaScience (2013)" justifies this intuitively by mentioning that this is analogous to precession: if you try to measure electrons e.g. with the Zeeman effect the precess on the other directions which you end up modifing.
Nothing makes the fact that your life is an illusion clearer than animations of molecular biology processes. You just have no idea what is going on inside your own body right now!
And don't get Ciro Santilli started on the brain and the impossibility of free will.
And yet, we live, oblivious to all of it.

Anime Updated 2025-07-16
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.
This does not seem to go deep into the Standard Model as Physics from Symmetry by Jakob Schwichtenberg (2015), appears to focus more on more basic applications.
But because it is more basic, it does explain some things quite well.
In the LC circuit:
You can kickstart motion in either of those systems in two ways:
