"Sounds like they’re crossing the beams - isn’t that bad?"

This city is headed for a disaster of biblical proportions.
What he means is Old Testament, Mr. Mayor, real wrath of God type stuff.
Fire and brimstone coming down from the skies! Rivers and seas boiling!
Forty years of darkness! Earthquakes, volcanoes...
The dead rising from the grave!
Human sacrifice, dogs and cats living together... mass hysteria!

God bless that movie if for no other reason than it's probably the last one Hollywood made in which they had the balls to make the EPA the bad guy. Also bless the movie for Sigourney Weaver.

The researchers then attached a rubidium atom to the resonator preventing light form [sic] entering the resonator thereby preventing the oscillation phase of the proton from changing. - Shouldn't that be "photon"? Article would be more convincing if it didn't require sic-ing twice in the same sentence.

LOL - excellent

To what end, I can't really say, because to me the whole idea of gaining control over the quantum realm is fundamentally hopeless, since it is axiomatic in Quantum Theory itself that this will not happen, as expressed by Quantum Uncertainty.

Thought you might find this theory interesting.

Thanks for the link, but I am out of sympathy with such projects.

I feel ones time might be more fruitfully spent perusing Herzberg, Atomic Spectra and Atomic Structure (1937)

On this election night, I’m feeling really cranked on about QM. I would just like to comment on the singlet and triplet spectroscopic states as per Herzberg, pg.75.

Traditionally, these are explained as spin 1/2 electrons being aligned or anti-aligned, to form spin 1 or spin 0 states, but this heuristic doesn’t really wash.

There are 2 X 2 = 4 states of the two electrons, represented as |++> , |+-> , |-+> , |—> in Dirac’s “bra - ket” notation, named for the inner product “bracket” notation, e.g. <+-|++> = 0 .

The “bra” is the dual of the “ket”, and their inner product represents a probability of finding the system in both states simultaneously. ( The ket is, I believe, the punning basis for Schroedinger’s cat. )

But there are two anti-aligned states, and they resolve into the triplet and the singlet thus:

triplet: |++> , |+-> + |+-> , |—>
singlet: |+-> - |-+>

So, there are TWO anti-aligned states: the spin 1 state with z-component 0, and the spin 0 state.

This defies heuristic explanation, except that the singlet is antisymmetric under exchange, and the Lz=0 triplet state is symmetric. It all works out beautifully. Learn to love it.

This is almost literally, the ABCs or 1+1=2, of atomic QM. It stands as rock.
