Local symmetries of the Lagrangian imply conserved currents Updated +Created
TODO. I think this is the key point. Notably, symmetry implies charge conservation.
More precisely, each generator of the corresponding Lie algebra leads to one separate conserved current, such that a single symmetry can lead to multiple conserved currents.
This is basically the local symmetry version of Noether's theorem.
Then to maintain charge conservation, we have to maintain local symmetry, which in turn means we have to add a gauge field as shown at Video "Deriving the qED Lagrangian by Dietterich Labs (2018)".
Forces can then be seen as kind of a side effect of this.
Can AGI be trained in simulations? Updated +Created
Or is real word data necessary, e.g. with robots?
Fundamental question related to Ciro's 2D reinforcement learning games.

Carl Mark Force Updated +Created
Full name Carl Mark Force IV, the fourth! As mentioned at www.vice.com/en/article/vv7dgj/great-moments-in-shaun-bridges-a-corrupt-silk-road-investigator (this made Ciro Santilli laugh quite hard:
Carl Mark Force IV - the other corrupt cop charged alongside Bridges - is pretty hard to beat, just name-wise.

Champaign-Urbana metropolitan area Updated +Created
It is quite comical that two separate towns were founded one next to the other right in the middle of nowhere. And that both have so slightly weird names.

Bicycle tire sizes Updated +Created
Yes, Sheldon he has separate American and British English versions of pages!!!
For example, Kross bicycle (2017) had a Schwalbe tyre with markings:
42-622 (28 x 1.60, 700x40C)
When inflated, the tires were about 3.5cm wide as measured with a ruler.
And the Mavic A319 rim had markings:
622x19C

Chill and eat your bread in peace Updated +Created
Ciro once told a friend that his ideal life would be to "just chill out and eat his bread in peace" (while also learning and teaching the sciences). Quote "Omar Khayyam's chill out quote" comes to mind. See also: Ciro Santilli's cheapness.
