Which country gets the most rain in the world?- "Of the 95 wettest countries in the world, Guinea, Solomon Islands and Sierra Leone are ranked the top three in order of maximum rainfall received on an average in a year, according to the World Statistics Pocket Book and the Statistical Yearbook of the United Nations. The records are for the period 1931-1960. Guinea, also known as the Republic of Guinea, with its capital named Conakry, is in Western Africa receives a monsoon-type of rainfall from June to November. Against the global weighted annual average rainfall of 9.627 cm, Guinea gets 37.84 cm, the Solomon Islands gets 32.90 cm and Sierra Leone gets 29.46 cm. Conakry is the wettest capital in the world and receives rainfall on an average of 134 days each year. India is the ninth wettest country with 21.68 cm of average annual rainfall. The UN World Statistics for 2007 record these figures: Guinea - 37.76 cm, Solomon Islands - 32.9 cm, Sierra Leone - 29.46 cm and India 24.01 cm.

Music first sent down a telephone line in 1876
Music first sent down a telephone line in 1876
So you think downloading music from the Internet via a phone line is a really cool modern thing? Not so.
In 1896, Thaddeus Cahill filed a patent on the "art of and apparatus for generating and distributing music electronically" and until 1914 he fed music signals down AT&T's telephone lines with his Telharmoniums apparatus. And he wasn't even the first. Elisha Gray transmitted music over a telephone line in 1876 - the same year the telephone was patented Alexander Graham Bell. Gray invented the first electronic music instrument in 1874, calling it the "Musical Telegraph."
(Other claims for the invention of the telephone include Antonio Meucci, Johann Philipp Reis, Innocenzo Manzetti, Charles Bourseul, Amos Dolbear, Sylvanus Cushman, Daniel Drawbaugh, Edward Farrar, and James McDonough. The debate over the invention of the telephone is discussed in detail at about.com - History of the Telephone)
Alexander Graham Bell also designed an experimental "Electric Harp" for speech transmission over a telephone line using similar technology to Gray's. Bell also was a teacher of speech to the deaf. In 1879 he created an audiometer to detect hearing loss. That is why the degrees of loudness came to be measured in bels or decibels.

Science fast facts
Music was sent down a telephone line for the first time in 1876, the year the phone was invented.
Sound travels through water 3 times faster than through air.
A square piece of dry paper cannot be folded in half more than 7 times.
Air becomes liquid at about minus 190 degrees Celsius.
Liquid air looks like water with a bluish tint.
A scientific satellite needs only 250 watts of power, the equivelant used by two hour light bulbs, to operate.
The thin line of cloud that forms behind an aircraft at high altitudes is called a contrail.
Radio waves travel so much faster than sound waves that a broadcast voice can be heard sooner 18,000 km away than in the back of the room in which it originated.
A US ton is equivalent to 900 kg (2000 pounds). A British ton is 1008 kg (2240 pounds), called a gross ton.
Industrial hemp contains less than 1% of THC, the psychoactive component of marijuana.
Since space is essentially empty it cannot carry sound. Therefor there is no sound in space, at least not the sort of sound that we are used to.
The Space Shuttle always rolls over after launch to alleviate structural loading, allowing the shuttle to carry more mass into orbit.
The word "biology" was coined in 1805 by Jean-Baptiste Lamarck.
Most of the air is about 78% nitrogen gas. Only 21% consists of oxygen. The remaining 1% consists of carbon dioxide, argon, neon, helium, krypton, hydrogen, xenon and ozone.
Argon is used to fill the space in most light bulbs. Neon is used in fluorescent signs. Fluorescent lights are filled with mercury gas.
Hydrogen gas is the least dense substance in the world.
Water expands by about 9% as it freezes.
The surface of hot water freezes faster than cold water but the rest of the water will remain liquid longer than in a cold sample.
The smallest transistor is 50-nanometres wide - roughly 1/2000 the width of a human hair.
A compass does not point to the geographical North or South Pole, but to the magnetic poles.
The double-helix structure of DNA was discovered in 1953 by James Watson and Francis Crick. The length of a single human DNA molecule, when extended, is 1.7 metres (5 ft 5 in).
In a desert, a mirage is caused when air near the ground is hotter than air higher up. As light from the sun passes from cooler to warmer air, it speeds up and is refracted upward, creating the image of water.
The typical bolt of lightning heats the atmosphere to 50,000 degrees Fahrenheit.
An electric oven uses one kilowatt-hour of electricity in about 20 minutes, but one kilowatt-hour will power a TV for 3 hours, run a 100-watt bulb for 12 hours, and keep an electric clock ticking for 3 months.
In the 6th century BC Greek mathematician Pythagoras said that earth is round - but few agreed with him.
Greek astronomer Aristarchos said in the 3rd century BC that earth revolves around the sun - but the idea was not accepted.
In the 2nd century BC Greek astronomer Erastosthenes accurately measured the distance around the earth at about 40,000 km (24,860 miles) - but nobody believed him.
In the 2nd century AD Greek astronomer Ptolemy stated that earth was the centre of the universe - most people believed him for the next 1,400 years.

origin encyclopedia
The word encyclopaedia is derived from two Greek words meaning "a circle of learning." The oldest known encyclopaedia was written in Greece about 2,000 years ago. It's no longer in existence. The oldest encyclopaedia in existence was written in the 1st century by Roman scholar Pliny the Elder; called Natural History, it consists of 37 volumes. The largest ever encyclopaedia is the 17th century Yung Lo Ta Tien encyclopaedia. Written by 2,000 writers, it was bound in 11,100 volumes. The first volume of Encyclopaedia Britannica was published in 1771, a year after Beethoven was born and 5 years before America declared independence.
