schrödinger's cat

So last night on "The Big Bang Theory" Sheldon used the paradox of Schrödinger's cat to explain the current state of Penny and Leonard's relationship as being unobserved so therfore both alive and dead at the same time. Schrödinger developed this theory to illustrate a proble in quantum mechanics.

Here are the basics from WhatIs.com:
We place a living cat into a steel chamber, along with a device containing a vial of hydrocyanic acid. There is, in the chamber, a very small amount of a radioactive substance. If even a single atom of the substance decays during the test period, a relay mechanism will trip a hammer, which will, in turn, break the vial and kill the cat. The observer cannot know whether or not an atom of the substance has decayed, and consequently, cannot know whether the vial has been broken, the hydrocyanic acid released, and the cat killed. Since we cannot know, the cat is both dead and alive according to quantum law, in a superposition of states. It is only when we break open the box and learn the condition of the cat that the superposition is lost, and the cat becomes one or the other (dead or alive). This situation is sometimes called quantum indeterminacy or the observer's paradox: the observation or measurement itself affects an outcome, so that the outcome as such does not exist unless the measurement is made. (That is, there is no single outcome unless it is observed.)

So why am I going on about this? I think we all keep things closed up in boxes. As long as it's in the box, there is no outcome. Until we open the box, we have the safety of knowing that our dream might be alive. We also live with the stress and fear that it might be dead. But we hesitate to open the box. As long as the box stays closed, we don't have to confront the possiblility of death.

The don't act because I fear the result of my action will be failure instead of success. As long as I don't act, failure is kept at bay and success is still a possibility.

I don't ask because I fear the truth may be contrary to my desired answer. As long as I don't ask, my favorable outcome still exists as a possiblity--though it doesn't truly change the answer.

I have a life full of metaphorically boxed up cats. It's time to open up the boxes and see which ones are alive and scratching.
