Where most of Ciro Santilli's ancestors came from, and why Ciro has the Italian nationality as well as Brazilian.
More specifically his paternal line comes from Gissi in the Abruzzo region.
Ciro feels really bad by the fact that he does not speak Italian and has never visited Gissi as of 2020.
He would likely be able to learn Italian in like 3 months because it is so similar to Portuguese and French which he already speaks.
For what it is worth though, Ciro Santilli does honestly love Europe, and feels a strong desire to make it even awesomer, along with the rest of the world. Despite this being a hopeless attempt due to having more than one natural language is bad for the world.
Ciro Santilli's knee by Ciro Santilli 37 Updated 2025-07-16
If Achilles' had his heel, Ciro had his knee.
First during University in Brazil while trying a kick up during the development of Cirodance his knee went a bit weird for a few weeks.
Then, just after arriving in France for École Polytechnique, the boys were playing indoor soccer, and to impress the girls Ciro was playing really hard, even took off his shirt, and suddenly when he was running by himself his knee snapped, he fell and it hurt like hell.
Ciro was on crutches for a few weeks, but the inflammation went away, but then he tried to play more soccer, but the knee was not as stable as before, and once he tried to run full speed, it slipped and hurt him a bit more (less severely) and so he gave up. For some reason it was not visible on the tomography made at the hospital.
Maybe Ciro should have investigated more though, certainly an experienced doctor could have done a hand pressure exam to determine which joint was damaged manually even. That was a medical failure.
So from this day on Ciro gave up on all interesting sports, and confined himself to more repetitive stuff like gym weights and cycling: Section "Ciro Santilli's sport practice". At Polytechnique he was forced to take up swimming as his mandatory sport, that was unbearably boring.
This defect is likely genetic since a close relative had similar problems.
But oh well, his then not-even girlfriend was impressed enough by the soccer or sorry enough for the sucker to marry him, so it worked out.
Repeat this mantra:
Only decentralize when inevitable.
Only decentralize when inevitable.
Only decentralize when inevitable.

We have everything and we have nothing
And some men do it in churches
And some men do it by tearing butterflies in half
and some men do it in Palm Springs
Laying it into butter-blondes with Cadillac souls
This stuck to Ciro's mind for some reason. His brain just keeps completing the sentence, over and over:
Ciro Santilli does it in his computers and in his labs!
The neutron temperature example is crucial: you just can't give the cross section of a target alone, the energy of the incoming beam also matters.

Maxwell's equations by Ciro Santilli 37 Updated 2025-07-16
Unified all previous electro-magnetism theories into one equation.
Explains the propagation of light as a wave, and matches the previously known relationship between the speed of light and electromagnetic constants.
The equations are a limit case of the more complete quantum electrodynamics, and unlike that more general theory account for the quantization of photon.
The system consists of 6 unknown functions that map 4 variables: time t and the x, y and z positions in space, to a real number:
  • , , : directions of the electric field
  • , , : directions of the magnetic field
and two known input functions:
  • : density of charges in space
  • : current vector in space. This represents the strength of moving charges in space.
Due to the conservation of charge however, those input functions have the following restriction:
Equation 1.
Charge conservation
.
Also consider the following cases:
  • if a spherical charge is moving, then this of course means that is changing with time, and at the same time that a current exists
  • in an ideal infinite cylindrical wire however, we can have constant in the wire, but there can still be a current because those charges are moving
    Such infinite cylindrical wire is of course an ideal case, but one which is a good approximation to the huge number of electrons that travel in a actual wire.
The goal of finding and is that those fields allow us to determine the force that gets applied to a charge via the Equation "Lorentz force", and then to find the force we just need to integrate over the entire body.
Finally, now that we have defined all terms involved in the Maxwell equations, let's see the equations:
Equation 2.
Gauss' law
.
Equation 3.
Gauss's law for magnetism

Equation 4.
Faraday's law

Equation 5.
