A cat is in a sealed steel box with a Geiger counter containing a minuscule amount of a radioactive substance, and a tube of poison. Depending on what happens in the box, the cat will either be dead or alive -- but it cannot be both.
To a quantum physicist, "Schrodinger's cat" neatly illustrates the failures of the so-called "Copenhagen interpretation" to take simple reality into account. To the layperson, it's pretty confusing. But at least we know Schrodinger's Cat is a cat.
As we told you last night, Sanrio
-- the company that makes Hello Kitty -- recently announced that the character is not, actually, a cat. What she actually is is a British girl with a pet cat that looks exactly like her, except that it walks on all fours.
In the wake of this unnerving revelation, the website Kotaku
contacted Sanrio for clarification. A spokesperson said:
"Hello Kitty was done in the motif of a cat. It's going too far to say that Hello Kitty is not a cat. Hello Kitty is a personification of a cat"
That sounds like kind of a tricky concept: unlike Schrodinger's cat, Hello Kitty is two things at once: a cat, and not a cat. To the layperson, it's pretty confusing. To an expert, it's simple.
So we contacted an expert: Peter Armstong's four-year-old daughter, Jasmine.
