| > electrons shells Not going away. It's based too directly in quantum mechanics principles, and the same tools are used in too may other problems with good results. If you talk to a hard core physicist, they may explain some minor corrections, but the simple model is 99% accurate and the corrections quite technical. Perhaps there is a better theory in the future, but it will be very weird, you really don't want to know it. > wave function collapse It's going away, but it may take 500 years. Nobody likes wave function colapse. There is people working to eliminate it, but we have no clue if it's hard, very hard or impossible. I think that a combination of the so-called-many-worlds-interpretation and something-something-decoherence will solve it in 50 years, or 100 years or 500 years. I'm optimistic, but it may take a while...... > pseudo-vectors Solved? The problem is drawing normal vectors that are 1-forms and pseudo-vectors that are mostly 2-forms in the same space. Most pseudo-vectors are like a tiny surface area instead of a tiny arrow. But people love to draw all of them as arrows and that causes the problem. Also, in special relativity the electric field (vector) and magnetic field (pseudo-vector) are combined in a single weird entity that fixes the problem. There is still the problem with the weak force, but I think it's solved once you replace mass with the Higgs boson. So it's "solved" if you like to use a little more math and want to translate it to everyone else that likes arrows. > relativistic mass Solved. Most modern Special Relativity books try to avoid relativistic mass. The problem is that you need number to accelerate to one side and a different number to accelerate to the front/rear. So it's better to skip it and use other equations. The usual "relativistic mass" is good for accelerations to one side to get circular movements, so it's nice for some problems. > xyz I have no idea what it means. |
Has almost nothing to do with actual orbitals. "Filling electron shells", "octets" are just idiotic old rule of thumb ideas only accidentally aligning with reality.
> wave function collapse
I think it's going away pretty fast as we exprimentally find quantum behaviors in increasingly macroscopic objects. At some point it will become clear that nothing collapses into particles and it's just that through interaction wavefunctions narrow down when they exchange some energy and momentum. But other interactions can spread them apart back again. We are gonna create consistent description of the process in both directions.
> pseudo-vectors
they are still used but they are gonna be replaced by bivectors as they are more natural
> relativistic mass
true that it's partially sovled, but we need a generation or two of people not mentioning at all in educational context or metioning it negatively for it finally go away ... today it's still treated as "useful educational metaphor" which it is not
> xyz
Basically breaking down math calculations to coordinate wise caluclations
People will stop doing that because most symbolic maths in education is going to be done with computers and rarely anyone will be doing any element-wise transforamtions on anything.
