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

Trapping Ions for Quantum Computing by Diana Craik (2019)
Source.
A basic introduction, but very concrete, with only a bit of math it might be amazing:
Sounds complicated, several technologies need to work together for that to work! Videos of ions moving are from www.physics.ox.ac.uk/research/group/ion-trap-quantum-computing.
A major flaw of this presentation is not explaining the readout process.

Gluon by Ciro Santilli 35 Updated +Created
Force carrier of quantum chromodynamics, like the photon is the force carrier of quantum electrodynamics.
One big difference is that it carrier itself color charge.

Diffie-Hellman key exchange by Ciro Santilli 35 Updated +Created
Based on the fact that we don't have a P algorithm for the discrete logarithm of the cyclic group as of 2020, but we do have an efficient algorithm for modular exponentiation. But nor do we have proof that one does not exist! Living on the edge as usual for public-key cryptography.

Borlotti beans by Ciro Santilli 35 Updated +Created
This looks a lot like the beans that Brazilians venerate and can be easily found in the United Kingdom as of 2020.
The more exact type seems to be pinto bean, but this is close enough.
2021-03: same but 2.5 teaspons, seems to be the right ammount.
2021-02-10: attempt 3: 500g 1 hour 30 minutes no pressure, uncontrolled water. Salt with one chorizo: put 3 teaspoons, it was a bit too much, going to do 2 next time and see.
2020-12-14: attempt 3: 250g of beans, 1.5l of water, 30 minutes pressure.
2020-11-30: attempt 2: 275ml of dry beans, about 50% of 500g bag, putting 1650 ml (6x) of water on pressure cooker Still had to throw out some water.
Density dry raw: 216 g/250 ml = 432 g / 500 ml = 500 g / 580 ml = 864 g/L
500 g dry expands to in water after 12 hours: 1200 ml
Therefore 500 g dry = 864 / 2 L = 432 ml expands about 3x.
Therefore, to the maximum 2.5L of the cooker with 8x dry volume water from this recipe I can use:
2500 = volume expanded bean + volume water = 3 volume dry bean + 8 volume dry bean = 11 volume dry bean
and so:
volume dry bean = 2500/11 = 227ml
which is about 227 / 580 = 40% of the 500 g bag.
After first try, I found that 8x volume of water is way, way too much. Going to try 6x next time.
