The Concept as Explained by Steve Martin:

In Steve Martin's Book Pure Drivel  he explains Schrodinger's principle through the following examples:

Original Premise  
A cat is placed in a box, together with a radioactive atom. If the atom decays, a hammer kills the cat; if the atom doesn't decay, the cat lives. As the atom is considered to be in either state before the observer opens the box, the cat must thus be considered to be simultaneously dead and alive.  
- Erwin Schrodinger, 1935

Wittgenstein's Banana
A banana is flying first class from New York to L.A. Two scientists, one in each city, are talking on the phone about the banana. Because it is moving in relationship to its noun, the referent of the word banana never occupies one space, and anything that does not occupy one space does not exist. Therefore, a banana will arrive at JFK with no limousine into the city, even though the reservation was confirmed in L.A.

Elvis's Charcoal Briquette
A barbecue is cooking wieners in an airtight space. As the charcoal consumes the oxygen, the integrity of the briquette is weakened. An observer riding a roller coaster will become hungry for wieners but will he thrown from the car when he stands up and cries, "Elvis, get me a hot dog."

Chef Boyardee's Bungee Cord
A bungee cord is hooked at one end to a neutrino, while the other end is hooked to a vibraphone. The neutrino is then accelerated to the speed of light, while the vibraphone is dropped off the Oakland Bay Bridge. The cord will stretch to infinite thinness, the neutrino will decay, and the vibraphone will be smashed by the recoiling bungee. Yet an observer standing on the shore will believe he hears Tchaikovsky's second piano concerto performed by Chef Boyardee's uncle Nemo.

Sacajawea's Rain Bonnet
Lewis and Clark are admiring Sacajawea's rain bonnet. Lewis, after six months in the wilderness, wants to wear the rain bonnet, even when it's not raining. Clark wants Sacajawea to keep wearing it and doesn't want to have to deal with Lewis, who conceivably could put on the bonnet and start prancing. However, an observer looking back from the twenty-first century will find this completely normal.

Apollo's Non-Apple Non-Strudel
Imagine Apollo running backward around the rings of Saturn while holding a hot dish of apple strudel. In another universe, connected only by a wormhole, is a dollop of vanilla ice cream. The vanilla ice cream will move inexorably toward the wormhole and be dumped onto the strudel. Yet wife swapping is still frowned upon in many countries.

Jim Dandy's Bucket of Goo
Jim Dandy is placed in a three-dimensional maze. His pants are tied at the ankles and filled with sand. Every time he moves to another dimension of the maze, he must review the movie Titanic, first with one star, then with two stars, then with three, while never mentioning its box office take. If he completes the maze, he will then be able to untie his pant-legs, and the spilling sand will form a bowling trophy that Jim Dandy may take home.

The Feynman Dilemma
A diner says to a waiter, "What's this fly doing in my soup?" And the waiter says, "it looks like the backstroke." Yet if the same scene is viewed while plunging into a black hole at the speed of light, it will look like a Mickey Mouse lunch pail from the thirties, except that Mickey's head has been replaced by a Lincoln penny.

George Hamilton's Sun Lamp
George Hamilton is dropped into an empty rental space next to a tanning salon on the dark side of the moon. There is no way into the salon except through an exterior door, but if George exits, it could mean dangerous exposure to deadly gamma rays. George could open his own tanning salon by tapping the phone lines from next door and taking their customers. And yet George is cooked when he exits the rental space while using a silver-foil face reflector.
