Probably the second-most clever epic poem I've seen on the internets.

From The Straight Dope, copied from here.

Dear Cecil:
Cecil, you're my final hope
Of finding out the true Straight Dope
For I have been reading of Schroedinger's cat
But none of my cats are at all like that.
This unusual animal (so it is said)
Is simultaneously live and dead!
What I don't understand is just why he
Can't be one or other, unquestionably.
My future now hangs in between eigenstates.
In one I'm enlightened, the other I ain't.
If you understand, Cecil, then show me the way
And rescue my psyche from quantum decay.
But if this queer thing has perplexed even you,
Then I will and won't see you in Schroedinger's zoo.
— Randy F., Chicago

Cecil replies:
Schroedinger, Erwin! Professor of physics!
Wrote daring equations! Confounded his critics!
(Not bad, eh? Don't worry. This part of the verse
Starts off pretty good, but it gets a lot worse.)
Win saw that the theory that Newton'd invented
By Einstein's discov'ries had been badly dented.
What now? wailed his colleagues. Said Erwin, "Don't panic,
No grease monkey I, but a quantum mechanic.
Consider electrons. Now, these teeny articles
Are sometimes like waves, and then sometimes like particles.
If that's not confusing, the nuclear dance
Of electrons and suchlike is governed by chance!
No sweat, though--my theory permits us to judge
Where some of 'em is and the rest of 'em was."
Not everyone bought this. It threatened to wreck
The comforting linkage of cause and effect.
E'en Einstein had doubts, and so Schroedinger tried
To tell him what quantum mechanics implied.
Said Win to Al, "Brother, suppose we've a cat,
And inside a tube we have put that cat at--
Along with a solitaire deck and some Fritos,
A bottle of Night Train, a couple mosquitoes
(Or something else rhyming) and, oh, if you got 'em,
One vial prussic acid, one decaying ottom
Or atom--whatever--but when it emits,
A trigger device blasts the vial into bits
Which snuffs our poor kitty. The odds of this crime
Are 50 to 50 per hour each time.
The cylinder's sealed. The hour's passed away. Is
Our pussy still purring--or pushing up daisies?
Now, you'd say the cat either lives or it don't
But quantum mechanics is stubborn and won't.
Statistically speaking, the cat (goes the joke),
Is half a cat breathing and half a cat croaked.
To some this may seem a ridiculous split,
But quantum mechanics must answer, "Tough shit.
We may not know much, but one thing's fo' sho':
There's things in the cosmos that we cannot know.
Shine light on electrons--you'll cause them to swerve.
The act of observing disturbs the observed--
Which ruins your test. But then if there's no testing
To see if a particle's moving or resting
Why try to conjecture? Pure useless endeavor!
We know probability--certainty, never.'
The effect of this notion? I very much fear
'Twill make doubtful all things that were formerly clear.
Till soon the cat doctors will say in reports,
"We've just flipped a coin and we've learned he's a corpse."'
So saith Herr Erwin. Quoth Albert, "You're nuts.
God doesn't play dice with the universe, putz.
I'll prove it!" he said, and the Lord knows he tried--
In vain--until fin'ly he more or less died.
Win spoke at the funeral: "Listen, dear friends,
Sweet Al was my buddy. I must make amends.
Though he doubted my theory, I'll say of this saint:
Ten-to-one he's in heaven--but five bucks says he ain't."
— Cecil Adams

Okay. That was win all the way through.

But now I have to ask...what's the MOST clever epic poem you've seen on the internet? I didn't realize that was even a genre.

Ask Vald about it, he may have an opinion.

Very nice, but for the record, I killed Schoredinger's cat with Occam's razor.

I see what you did there.

I never did quite get Schrodinger's Cat, though, anyone care to explain it to me? I mean, the cat CAN'T be both alive or dead as far as I understand it--its alive/dead whether you see it or not. I dunno, maybe I'm missing the point. The Copenhagen Interpretation actually makes more sense to me than the initial theory itself.

I don't get it entirely myself, but I think it has something to do with a quantum particle either being "there" or "not there" at random, and you can't determine which it is..so it's both there and not there at the same time, so long as you're not observing it (since observing it sets, and possibly changes, the result).

The idea being that if the particle is "there", it triggers a poison in the box that kills the cat. If it's "not there", the poison is never triggered and the cat lives. There=dead cat, not there=live cat.

Since the particle is there and not there simultaneously, while not being observed, and the life of the cat depends on the presence of the particle, the cat is both alive and dead while in the box. Once you open the box, though, it's one or the other.

Again, it's complicated stuff that makes my head hurt, but that's about the gist of it. I think.

OOOOOH, okay. Its still about as clear as mud, and it makes my head hurt like a bitch too, but that at least clarifies what I was confused on. I was focused on the actual, physical cat, not the particles. That makes more sense. ...Kind of. Laughing

You really want your head to hurt, though, check out this Cracked article: http://www.cracked.com/blog/5-scientific-theories-head-explode/





And not to spoil it, but this is my favorite part:

Right now, on your computer screen, are approximately 10,000 galaxies.

Each of those galaxies contains anywhere from ten million to one trillion stars.

The average star is roughly a million times the size of Earth.

And yet, with all that junk, the Universe is more than 90 percent empty space.

All of that, in this tiny photo. A photo that took 400 orbits and 800 exposures to take.

And the kicker? The photo covers one thirteen-millionth of the entire night sky.

...Since we can only observe stellar bodies that have had some effect on us (usually bombarding us with light), there is an outer limit to what we can see of the universe. Hence, the “observable universe.” What about the rest? The parts of the universe beyond our Starcraft-style fog of war? Well, according to some math we have no interest in going into, the size of the “actual” universe is so large that if the universe we just described (the impossibly, mind-bogglingly large one) were the size of a quarter, the actual universe would be the size of the Earth.



I believe it was for realizations like that that the phrase "holy fucking shit" was invented. Shocked

Basically, Schrodinger's Cat is a very poor metaphor designed to explain a very real phenomenon that happens on the subatomic level. Since the metaphor is so ridiculously counterintuitive, explaining it is actually more tiresome and didactic than just explaining the actual phenomenon. In short, Schrodinger was a condescending asshole who attempted to simplify an idea for peers he felt were intellectually inferior to him, but he was too out of touch to do so in a reasonable fashion.

^ That actually makes a whole lot of sense. I understand the actual concept that Schrodinger was trying to explain. (Well, UNDERSTAND is the wrong word, but I get what *happens.*) My stumbling block was always, "what the fuck does that have to do with a cat that is obviously alive or dead whether you look at it or not?"

I thought he was trying to point out a flaw with quantum theory...

Not with quantum theory itself, but with the Copenhagen Interpretation of it. That interpretation says that the state of any particle is probabilistic and indeterminate until the act of measurement. The whole point and genius of Schroedinger's thought experiment is to construct an elaborate scenario which brings that indeterminacy from the microscopic to the macroscopic level and to show the counterintuitive results that follow. What it breaks down to is this: If the Copenhagen Interpretation is correct, then the cat is both alive and dead until the act of measurement. Since that runs completely counter to our intuition (if the cat survived it wouldn't remember being both dead and alive for example), that means there is something wrong with the Copenhagen Interpretation of quantum mechanics.

Reading this reminded me of something out of one of my books:

Call it observed Schroedinger's Human if you will.
