1240: "Quantum Mechanics"

Postby dalcde » Fri Jul 19, 2013 11:22 am UTC

Title text: "You can also just ignore any science assertion where 'quantum mechanics' is the most complicated phrase in it."

According to quantum mechanics, you can't know both the position and momentum of a particle precisely.

EDIT: Just realized that my statement is a counter-example for both the comic AND the title-text.

… unless you actually understand quantum mechanics.

This rule only makes sense, if you don’t, and can’t check if the other person does.

Also, it makes much more sense, to ignore it because it contains the unword “soul”. A clear indicator for a lingering religious schizophrenic delusion.

I am also confuse why the word soul relate the quantum mechanics topic. I think they are far different from each other.

A curious but possibly related protip that I've noticed: You can ignore any sentence that uses the phrase "quantum leap", while "quantum jump" usually means that the writer has at least a minimal clue about its meaning. For some reason, the MSM and most marketers have settled on "leap" as what quantums (whatever they are) do.

An example I read recently said that a particular company had made a quantum leap in income last year. My immediate thought was "Did their income actually increase by exactly $0.01?" But that's not at all what it meant; the writer was using "quantum" to mean "an unspecified but huge amount", and indicated this by the use of "leap".

Actually Schrodinger's cat would only know if it is alive... and only a moment after the point in time where the probability was 50/50 due to a natural delay beings have between observation and comprehension.

Does this also apply to "due to quantum effects"? Because that rules out large portions of a couple of my textbooks.

And the funny thing is, they weren't even wrong (no, I'm not using it in that sense) - considering that at its root, "quantum" simply means "amount", any usage is highly dependent on the specific context / expression - in this case, all they said the income took a leap in amount which is exactly what they meant. "smallest discrete quantity" is merely one of the words current meanings, "quantum leap" is an arguably even older but equally valid one.

Anyway, it's astonishing how many people misunderstand "observed" in quantum-related discussions to mean "by a self-aware being" instead of what it actually means ("interacting with anything at all ")...

I started ignoring quantum mechanics when it started involving a one-dimensional particle moving in a two-dimensional box... (maybe that was just the lecturer though...)

Hey, of course wolpies have souls! Besides, "what is 'god' spelled backwards?"

Then there was the dedicated fisherman. The sole purpose of his soul was to provide people with sole.

Only true if it has a soul.... or at least if we can prove cats are self-aware. Heck, how do you know you're alive? You have no comparison state that you can recall (deadness).

I am satisfied that our pet cat, when I was a child, did not have short-term memory extending out to 15 seconds.

Quantum Leap was a TV series from the late 80s and early 90s starring Scott Bakula and Dean Stockwell. The major premise was that of a time traveller (limited to his own lifetime) who woke to find himself replacing another person, appearing as them to those around him, and required to put right what once went wrong by preventing some tragedy that occurred in the original history with the aid of his invisible friend - an observer from his home future with access to historical records.

Looks like you made a mistake (or, to be precise, an odd number of mistakes) while negating the quantifiers involved.

See, this would be less prevalent if many-worlds was the dominant interpretation. Then we wouldn't have to worry about who is and isn't an observer because "observer" is no longer anything that has to do with quantum mechanics. Although, then people would latch onto the "every possible configuration of the world exists at once, sort of" part. Never mind that only configurations with high amplitudes matter in the first place...

Also, how does the stick guy know dogs can be observers? Even from the Copenhagen point of view (and assuming the dog has just collapsed/became entangled with a qubit in a superposition of two states), the dog is in a superposition of having experienced one state or the other. This would also be the case if anybody else got to the qubit first. The wavefunction doesn't collapse/decohere until you personally observe it/entangle your mind with it.

I have experienced a comparison state. I can assure you that anyone 1.5 hours into a "pre-meeting" before an actual meeting, the purpose of which is to discuss the overuse of meetings, has experienced deadness.

This question was settled definitely by Bobby Byrd's 1971 proof.
I know you got soul / If you didn't you wouldn't be in here

This can be formalized as
!soul => !here
Which is simply the contrapositive version of
here => soul
The proof, with its Sartrian overtones, didn't get the widespread attention it deserved largely on account of the unorthodox publication route chosen by Byrd: namely, releasing it as a kick-ass funk tune backed by the J.B.s.

Does this protip also apply to any sentence that mentions quantum chromodynamics? I have no idea what QCD but it sounds cool.

As to "Quantum Leap", i like Scott Bakula and i think he resents you putting the knock on his show. Now ST:E is another matter.

I've actually helped physicists code QCD simulations, and *still* don't understand what it means!. :lol:

And quantum computing is waaay over-hyped. I acknowledge that it may have some applications, but have yet to see a real-world practical example. Yet some people seem to think it is going to solve all the problems of mankind. Get a grip.

Quantum computing is widely misunderstood. It will be much more effective at solving a certain subset of problems that classical computing takes an unfeasible amount of time to solve. This tells me already that quantum computers will potentially be able to factorise large products of few primes in polynomial time, and offer a polynomial or better speedup compared to current classical computing capabilities for many other problems.
