Interesting facts
Aircraft Carrier
An aircraft carrier gets about 6 inches per gallon of fuel.
Airplanes
* The first United States coast to coast airplane flight occurred in 1911 and
took 49 days.
* A Boeing 747s wingspan is longer than the Wright brother's first flight
(120ft).
Aluminum
The Chinese were using aluminum to make things as early as 300 AD Western
civilization didn't rediscover aluminum until 1827.
Automobile
George Seldon received a patent in 1895 - for the automobile. Four years later,
George sold the rights for $200,000.
Coin Operated Machine
The first coin operated machine ever designed was a holy-water dispenser that
required a five-drachma piece to operate. It was the brainchild of the Greek
scientist Hero in the first century AD.
Compact Discs
Compact discs read from the inside to the outside edge, the reverse of how a
record works.
Computers
* ENIAC, the first electronic computer, appeared 50 years ago. The original
ENIAC was about 80 feet long, weighed 30 tons, had 17,000 tubes. By comparison,
a desktop computer today can store a million times more information than an
ENIAC, and 50,000 times faster.
* From the smallest microprocessor to the biggest mainframe, the average
American depends on over 264 computers per day.
* The first "modern" computer (i.e., general-purpose and program-controlled) was
built in 1941 by Konrad Zuse. Since there was a war going on, he applied to
the German government for funding to build his machines for military use, but
was turned down because the Germans did not expect the war to last beyond
Christmas.
* The computer was launched in 1943, more than 100 years after Charles Babbage
designed the first programmable device. Babbage dropped his idea after he
couldn't raise capital for it. In 1998, the Science Museum in London, UK, built
a working replica of the Babbage machine, using the materials and work methods
available at Babbage's time. It worked just as Babbage had intended.
Electric Chair
The electric chair was invented by a dentist, Alfred Southwick.
E-Mail
The first e-mail was sent over the Internet in 1972.
Eye Glasses
The Chinese invented eyeglasses. Marco Polo reported seeing many pairs worn by
the Chinese as early as 1275, 500 years before lens grinding became an art in
the West.
Glass
If hot water is suddenly poured into a glass that glass is more apt to break if
it is thick than if it is thin. This is why test tubes are made of thin glass.
Hard Hats
Construction workers hard hats were first invented and used in the building of
the Hoover Dam in 1933.
Hoover Dam
The Hoover Dam was built to last 2,000 years. The concrete in it will not even
be fully cured for another 500 years.
Limelight
Limelight was how we lit the stage before electricity was invented. Basically,
illumination was produced by heating blocks of lime until they glowed.
Mobile (Cellular) Phones
As much as 80% of microwaves from mobile phones are absorbed by your head.
Nuclear Power
Nuclear ships are basically steamships and driven by steam turbines. The reactor
just develops heat to boil the water.
Oil
The amount of oil that is used worldwide in one year is doubling every ten
years. If that rate of increase continues and if the world were nothing but
oil, all the oil would be used up in 400 years.
Radio Waves
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.
Rickshaw
The rickshaw was invented by the Reverend Jonathan Scobie, an American Baptist
minister living in Yokohama, Japan, built the first model in 1869 in order to
transport his invalid wife. Today it remains a common mode of transportation in
the Orient.
Ships & Boats
* The cruise liner, Queen Elizabeth 2, moves only six inches for each gallon of
diesel that it burns.
* The world's oldest surviving boat is a simple 10 feet long dugout dated to
7400 BC. It was discovered in Pesse Holland in the Netherlands.
* Rock drawings from the Red Sea site of Wadi Hammamat, dated to around 4000 BC
show that Egyptian boats were made from papyrus and reeds.
* The world's earliest known plank-built ship, made from cedar and sycamore wood
and dated to 2600 BC, was discovered next to the Great Pyramid in 1952.
* The Egyptians created the first organized navy in 2300 BC.
* Oar-powered ships were developed by the Sumerians in 3500 BC.
* Sails were first used by the Phoenicians around 2000 BC.
Silicon Chip
A chip of silicon a quarter-inch square has the capacity of the original 1949
ENIAC computer, which occupied a city block.
Skyscraper
The term skyscraper was first used way back in 1888 to describe an 11-story
building.
Sound
Sound travels 15 times faster through steel than through the air.
Telephones
There are more than 600 million telephone lines today, yet almost half the
world's population has never made a phone call.
Television
Scottish inventor John Logie Baird gave the first public demonstration of
television in 1926 in Soho, London. Ten years later there were only 100 TV sets
in the world.
Traffic Lights
Traffic lights were used before the advent of the motorcar. In 1868, a lantern
with red and green signals was used at a London intersection to control the
flow of horse buggies and pedestrians.
Transistors
More than a billion transistors are manufactured... every second.
VCR's

World Trade Center

fashion, instead of simply falling over on their sides. This design feature
saved hundreds, perhaps thousands of lives on Sept. 11, 2001, when they were
destroyed by terrorists.
