Schrödinger's cat, often described as a paradox, is a thought experiment devised by Austrian physicist Erwin Schrödinger around 1935. It attempts to illustrate what he saw as the problems of the Copenhagen interpretation of quantum mechanics when it is applied beyond just atomic or subatomic systems.

In simple terms, the thought problem involves a cat placed in an opaque box with a sealed vial of poison that will break open at an uncertain time. Since no one knows when or if the poison has been released, until the box is opened, the cat might be thought of as both alive and dead, until the box is opened, and the cat is observed by someone else.

The concept of superposition, one of the strangest in quantum mechanics, helped provoke Schrödinger's conjecture. Broadly stated, the superposition is the combination of all the possible positions of a subatomic particle. The Copenhagen interpretation implies that the superposition only undergoes collapse into a definite state at the exact moment of quantum measurement.

Schrödinger's mind-game was meant to criticize the strangeness of this. Influenced by a suggestion of Albert Einstein, Schrödinger extrapolated the concept to a larger scale. He proposed a scenario with a cat in a sealed box, where the cat's life or death was dependent on the state of a subatomic particle. According to Schrödinger, the Copenhagen interpretation implies that the cat remains both alive and dead until the box is opened.

Schrödinger did not wish to promote the idea of dead-and-alive cats as a serious possibility; quite the reverse: the thought experiment serves to illustrate the bizarreness of quantum mechanics and the mathematics necessary to describe quantum states. Several interpretations of quantum mechanics have been put forward in an attempt to resolve the paradox. How they treat it is often used as a way of illustrating and comparing their particular features, strengths and weaknesses.

BACK TO ME.

k indeed this is rather interesting.
but that's how this quantum theory is.
the quantum theory allows
magnificent numbers of possibilities
to every situation.
however it is restricted that actions sow results.
thus bringing this very slight contradiction if you understand what i mean.
following up to explain.
even though it allows possibilities,
but results for a knife being stab in to your heart
would no doubt mean death.
make sense?
however, they have came to the conclusion
of the many world paradox,
that the other person in another dimension or world
would survive from this stab in the heart.
which would be hard to believe.
well, is contradicting but,
science IS explains the illogical to the logical.

its yours truly,
signing off.
