Quantum Theory Rebuilt From Simple Physical Principles | Quanta Magazine

Administrator

This is kinda interesting:

https://www.quantamagazine.org/quantum-theory-rebuilt-from-simple-physical-principles-20170830/

Basically look at it like this:

- Relativity: Is founded on a few simple physical principles like the limit on the speed of light.

- Quantum Theory: Is founded on equations that match observation.

Both make sense. But QT hasn't that satisfying basis that relativity has.

Apparently a bunch of folks are trying to fix that.

Stephen will like this:

Some researchers suspect that ultimately the axioms of a quantum reconstruction will be about information: what can and can’t be done with it. One such derivation of quantum theory based on axioms about information was proposed in 2010 by Chiribella, then working at the Perimeter Institute, and his collaborators Giacomo Mauro D’Ariano and Paolo Perinotti of the University of Pavia in Italy. “Loosely speaking,” explained Jacques Pienaar, a theoretical physicist at the University of Vienna, “their principles state that information should be localized in space and time, that systems should be able to encode information about each other, and that every process should in principle be reversible, so that information is conserved.” (In irreversible processes, by contrast, information is typically lost — just as it is when you erase a file on your hard drive.)

Mmm Neil DeGrasse Tysson, and Guy Consolmagno talked about quantum mechanics some on Nova (love watching that on youtube)

(LOL I still don't get it and asked help understanding it many people):

Basically the new guess is some how particles are actually just energy. That energy goes reely reely fast so fast in fact it seems (to people like me) that say a

beer cup at second street is solid. so can hold beer, great hardy food etc.

So what if (Elon Musk and Brian Green) Ask: their's smaller and smaller particles? are they connected somehow? and is it small and smaller untill you get to the qunatum (reel reely reeely small level)

Like possibly smaller even than a quark small. I happily differ to others as to if Fermi lab has been able to figure out how likely that might be.

Relativity is indeed very awsome ^_^ Einstein is awsome. I also LOVE reading Hawkings stuff. He's recently asking a simillar question to me:

"Wait so were all made of star stuff and energy? How does that work" I don't know. I love that I don't.

Isn't Quantum Energy guessing that at reely reely small levels what happens between kinds of particles? And did they figure out why this happens yet?
