knock, knock, knock “PENNY” knock, knock, knock “PENNY” knock, knock, knock “PENNY”
I caught that punk cat and beat it’s @ss.
and how many lab dollars did THAT cost;)
It’s only “spooky” if you try to conceive of photons as classical objects. Of course, they are not. They obey Bose-Einstein statistics. Why isn’t that spooky? ( It is! ... if you think about it. )
The article implies, if I’m reading it correctly, that information can be passed between the entangled photons. If so, it might one day provide instantaneous communication with spacecraft. No time lag. We could drive a rover on Mars in real time.
I'll raise you one Hello Kitty!

Your childhood has been torn asunder by the Gods that once gifted you. In preparing a Hello Kitty retrospective for the Japanese American National Museum, University of Hawaii Anthropologist Christine R. Yano was given one major correction by Hello Kitty owners Sanrio (via LA Times):
“Hello Kitty is not a cat. She's a cartoon character. She is a little girl. She is a friend. But she is not a cat. She's never depicted on all fours. She walks and sits like a two-legged creature. She does have a pet cat of her own, however, and it's called Charmmy Kitty.”
Indeed, after rigorously applying a variation of the “Duck test,” it all became clear: she only kind of looks like a cat, she doesn't walk like a cat, and she doesn't talk like a cat (although I can't recall her ever making a noise). She's also, according to Yano, British. Huh.
Fear not, though! We did the research, and Keroppi is still a frog.
Nifty! Thanks for posting!
I have it on good authority that it is NOT Schrodinger’s Cat! It belonged to someone else...
They are neither alive, nor dead. We don’t know.
This seems to demonstrate a kind of entanglement in the macro world that I personally had never seen before. No obvious reason why this couldn’t be scaled up indefinitely. Would be interesting with gamma rays and weapons application.
Not a cat ping...
The problem, if there is one, is the observer.
but is the cat dead or alive......not that much different than Young’s double slit or group action at a distance
"Technically, a cat locked in a box may be alive or it may be dead. You never know until you look. In fact, the mere act of opening the box will determine the state of the cat, although in this case there were three determinate states the cat could be in: these being Alive, Dead, and Bloody Furious."
- Terry Pratchett
Author Unknown:
Schrodinger, 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 discoveries 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 them is and the rest of them was.”
Not everyone bought this. It threatened to wreck,
The comforting linkage of cause and effect.
Even Einstein had doubts, and so Schrodinger 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 hours pass away. Is,
Our pussy still purring? Or pushing up daisies?
Now, you’d say that 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 for sho’:
There are 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. But 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 finally 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.”
It's brought together physicists and non science oriented cat lovers together on one thread.
It's positively multi-cultural!
