An American magazine held a competition, inviting its readers to submit new scientific theories on ANY subject. Below are the winners:

5th place (Subject: Probability Theory)
If an infinite number of rednecks riding in an infinite number of pickup trucks fire an infinite number of shotgun rounds at an infinite number of highway signs, they will eventually write the complete works of Shakespeare in Braille.

4th place (Subject: Bio-Mechanics)
Why Yawning Is Contagious: You yawn to equalize the pressure on your eardrums. This pressure change outside your head unbalances other people's ear pressures, so they then yawn to even it out.

3rd place (Subject: Symbolic Logic)
The Chinese are technologically underdeveloped because each of their alphabetical characters represents a whole word or phrase, rather than a single letter. Thus they cannot use acronyms to communicate technical ideas at a faster rate.

2nd place (Subject: Newtonian Mechanics)
Deforestation may cause earthquakes, tidal waves, or even the total destruction of our planet. Just as a figure-skater's rate of spin increases when the arms are brought in close to the body, the cutting down of tall trees may cause the Earth to spin dangerously fast on its axis with disastrous results.

Winner (Subject: Perpetual Motion)
When a cat is dropped, it always lands on its feet, and when toast is dropped, it always lands buttered side down. Therefore, if a slice of toast is strapped to a cat's back, buttered side up, and the animal is then dropped, the two opposing forces will cause it to hover, spinning inches above the ground. If enough toast-laden felines were used, they could form the basis of a high-speed monorail system.

haha!

One day an ape escaped from the Bronx Zoo. They searched for him everywhere, in every borough. They announced his disappearance on the radio and television as well as the newspapers. But, no one reported seeing the ape.

At last, he was discovered in the New York Public Library. Officials of the zoo as well as the animal handlers were summoned to the library. They found the ape sitting at a desk in the reading room with two books spread out in front of him. The ape was reading with great concentration. One book was the Bible; the other written by Darwin.

The zoo keepers asked the ape what he was doing. The ape replied, "I'm trying to figure out whether I am my brother's keeper or whether I am my keeper's brother."

haha!

Today's question: What in the world is electricity and where does it go after it leaves the toaster?

Here is a simple experiment that will teach you an important electrical lesson: On a cool dry day, scuff your feet along a carpet, then reach your hand into a friend's mouth and touch one of his dental fillings. Did you notice how your friend twitched violently and cried out in pain? This teaches one that electricity can be a very powerful force, but we must never use it to hurt others unless we need to learn an important lesson about electricity. It also illustrates how an electrical circuit works. When you scuffed your feet, you picked up batches of "electrons", which are very small objects that carpet manufacturers weave into carpet so that they will attract dirt. The electrons travel through your bloodstream and collect in your finger, where they form a spark that leaps to your friend's filling, then travel down to his feet and back into the carpet, thus completing the circuit.

AMAZING ELECTRONIC FACT:
If you scuffed your feet long enough without touching anything, you would build up so many electrons that your finger would explode! But this is nothing to worry about unless you have carpeting.

Although we modern persons tend to take our electric lights, radios, mixers, etc. for granted, hundreds of years ago people did not have any of these things, which is just as well because there was no place to plug them in. Then along came the first Electrical Pioneer, Benjamin Franklin, who flew a kite in a lightning storm and received a serious electrical shock. This proved that lightning was powered by the same force as carpets, but it also damaged Franklin's brain so severely that he started speaking only in incomprehensible maxims, such as, "A penny saved is a penny earned." Eventually he had to be given a job running the post office.

After Franklin came a herd of Electrical Pioneers whose names have become part of our electrical terminology: Myron Volt, Mary Louise Amp, James Watt, Bob Transformer, etc. These pioneers conducted many important electrical experiments. Among them, Galvani discovered (this is the truth) that when he attached two different kinds of metal to the leg of a frog, an electrical current developed and the frog's leg kicked, even though it was no longer attached to the frog, which was dead anyway. Galvani's discovery led to enormous advances in the field of amphibian medicine. Today, skilled veterinary surgeons can take a frog that has been seriously injured or killed, implant pieces of metal in its muscles, and watch it hop back into the pond. However, water is a great conductor of electricity and the frog is immediately electrocuted.

But the greatest Electrical Pioneer of them all was Thomas Edison, who was a brilliant inventor despite the fact that he had little formal education and lived in New Jersey. Edison's first major invention in 1877 was the phonograph, which could soon be found in thousands of American homes, where it basically sat until 1923, when the record was invented. But Edison's greatest achievement came in 1879 when he invented the electric company. Edison's design was a brilliant adaptation of the simple electrical circuit: the electric company sends electricity through a wire to a customer, then immediately gets the electricity back through another wire, then (this is the brilliant part) sends it right back to the customer again.

This means that an electric company can sell a customer the same batch of electricity thousands of times a day and never get caught, since very few customers take the time to examine their electricity closely. In fact, the last year any new electricity was generated was 1937.

Today, thanks to men like Edison and Franklin, and frogs like Galvani's, we receive almost unlimited benefits from electricity. For example, in the past decade scientists have developed the laser, an electronic appliance so powerful that it can vaporize a bulldozer 2000 yards away, yet so precise that doctors can use it to perform delicate operations to the human eyeball, provided they remember to change the power setting from "Bulldozer" to Eyeball."
