Schrödinger's Cat

Big Bang Theory is by far my favorite show on TV right now.  It is smart and funny without being mean-spirited or too bawdy.  On one of the earlier episodes, Leonard has asked Penny out on a date.  Neither knows whether or not they should go through with it, and both end up asking the socially inept Sheldon for advice. Sheldon's answer to their queries is the story of Schrödinger's Cat.  If you would like to see the clip in which Sheldon explains Schrödinger's Cat, click this link here.  After seeing the episode several times, I decided that I would do a little research into Schrödinger's Cat and I came across the following explanatory poem from The Straight Dope.  I hope that you enjoy it as much as I did.

The story of Schroedinger's cat (an epic poem)

May 7, 1982
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

Big Bang! I haven't enjoy a sitcom as much since Seinfeld or Third Rock from the Sun.
My first exposure to Schrodinger's Cat was the song by Tears for Fears. Which I'll be humming all day now.

I was born in the '80s and I don't understand my generation's pop culture.

I love BBT! It is funny as can be! And I love the Schrodinger's Cat episode, it was a rerun the other night, so this was fresh in my mind.

Love the poetry. Nice way to explain the unexplainable.

Peace <3

I haven't watched the show, but as a a bisexual guy (I neither like men nor women yet I like them both) with a physics degree, I enjoyed this post.
