My affair with nonsense trivia continues :-)

Several of the facts on Snapple caps have been found to be incorrect or out of date, including:

#1 A goldfish's attention span is three seconds. This theory was tested by Discovery's MythBusters. The experiment consisted of training several goldfish to complete a maze. They concluded that a goldfish's attention span and memory retention lasts well over 3 seconds.

#5 "Camels have three eyelids". In fact they have six (three per eye).

#31 “The average human will eat an average of eight spiders while sleeping.” This statistic was made up in 1993 as an example of the absurd things people will believe simply because they come across them on the internet, as uncovered by Snopes.

#36 "A duck's quack doesn't echo" Tested by Snopes and Mythbusters. Both tests concluded that a duck's quack does echo but is hard to distinguish.

#69 "Caller ID is illegal in California." There is no law against Caller ID in the state, though there were lengthy debates about legalizing it in the early 90's.

#77 "No piece of paper can be folded in half more than 7 times." This myth was put to the test by the Discovery Channel show MythBusters, who folded a piece of paper 11 times. The piece of paper used in MythBusters was an oversized piece of paper and thinner than a standard 8.5"x11" inch piece of paper.

#114 "The oldest known animal was a tortoise, which lived to be 152 years old" Currently the oldest living animal, a tortoise named Tu'i Malila, lived to be 188 years old.

#145 "Lake Superior is the world's largest lake." The Caspian Sea is considered the largest lake, Lake Superior is the largest freshwater lake by surface area. The largest freshwater lake by volume is Lake Baikal in Siberia.

#146 "The smallest county in America is New York County, better known as Manhattan." Falls Church, Virginia, is the smallest functional county at 2.0 square miles. (Kalawao County, Hawaii is also smaller but is technically part of Oceania, and not either of the American continents)

#162 "The temp. of the sun can reach 15 million degrees F." The core reaches temperatures of 25 million degrees F and the surface reaches only 10,000 degrees F, either way it's wrong. The Raspberry Iced Tea bottle itself also provides inaccurate information regarding the sun's temperature. An arrow on the bottle's sticker points to a picture of the sun with a following statement reading, "if you were 100 billion degrees, you'd be thirsty too!" The sun does not reach the temperature of 100 billion degrees.

#163 "The first penny had the motto 'Mind your own business.'" is actually false. The first penny has the motto "Mind your business".

#171 "The most sensitive parts of the body are the mouth and fingertips". The eyeballs have more nerve endings than all of these.

#180 "The first VCR was made in 1956 and was the size of a piano." The first VTR (Video Tape Recorder) was made in 1956. VCR's (video cassette recorders) came along in the 1970s.

#334 "Thomas Edison coined the word "hello" and introduced it as a way to answer the phone." The word "hello" was used in print in Roughing It by Mark Twain in 1872, while the telephone was invented in 1876.

#362 "'Arachibutlphobia' is the fear of peanut butter sticking to the roof of your mouth." The correct spelling is 'arachibutyrophobia'.

#383 "Mount Katahdin in Maine is the first place in the U.S. to get sunlight each morning." The town of Lubec, Maine (the easternmost town in the U.S.) is the first place in the U.S. to get sunlight each morning, although some believe Cadillac Mountain on Mount Desert Island (near Bar Harbor, Maine) sees the first sunlight.

The Monte Hall problem

Suppose you're on a game show, and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what's behind the doors, opens another door, say No. 3, which has a goat. He then says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice?

Wikipedia says it is to your advantage to switch the door!!!

http://en.wikipedia.org/wiki/Monty_Hall_problem

But I agree with another reader who says that Wiki is wrong here:

Here's the example given by the reader:

When you flip a coin, the odds of it coming up HEADS is 1 in 2. {I know you all knew that.}
What are the odds of flipping a coin 8 times and getting all HEADS? 1 in 256.
Okay, so you flip a coin 7 times and get 7 HEADS. What are the odds that the next flip will come up HEADS?

1 in 2 of course. That's because previous results have no influence on future probability.

That's where the Monte Hall "puzzle" falls down. The previous action of Monte removing one of the doors has NO EFFECT on the future probability of which door the car is behind. There are 2 doors, so the odds are 1 in 2 that they already have the right door, and 1 in 2 that switching will get them the car.
