The History Of The Airship
.... easy passage through the air, these Airships could reach speeds up to
10mph with a 5hp steam engine propeller.
The first successful airship was that of the French engineer and inventor Henri
Giffard, who constructed in 1852 a cigar-shaped, non-rigid gas bag 44 m (143 ft)
long, driven by a screw propeller rotated by a 2.2-kw (3-hp) steam engine. He
flew over Paris at a speed of about 10 km/hr (about 6 mph). Giffard's airship
could be steered only in calm or nearly calm weather. The first airship t .....

Animation
.... of several rules of animation, which animators around the world
follow. The first rule of animation is that an animator must hold the
understanding of the techniques used to produce single cells of animation.
Second rule, and one of the most important ones is that, the animator must have
great patience, so that his or her piece of artwork is not rushed, to prevent
the animation from looking choppy and not as smooth as it should look. Finally
what is required from an animator is "it takes commitment .....

HDTV
.... for 50 years. But with today's technology, a new
standard has been in the works, HDTV.
In September 1992 NBC's WRC-TV in Washington DC became the first
television station in the country to send HDTV signals over the air waves. WRC-
TV's general manager then stated, "With advanced digital high-definition
television, viewers will experience unmatched picture quality and superior sound
resolution."
There are many pro's and con's regarding having HDTV as the new standard.
Not all broadcasters are interest .....

How Technology Has Hurt Us

problem by recycling.
Air conditioners are using up allot of our electricity. There are times
in the summer when brown outs happen because if our excessive use of the air
conditioners. Freon gets released into our environment.
Today people are being kept alive longer and longer. People that have
no chance of recovery are being kept alive on ventilators. This causes a great
expense to society and an emotional stress on the family. Even thou .....

Technology Spontaneously Approaching `Humanity' With The Passage Of Time
.... certain tasks, and as
technological tools, the T800 and the replicant are deigned to meet specific
specifications. In Terminator 2, the T800 is a multipurpose cyborg assigned to
save John Connor, given a series of “mission parameters,” initially
characterized by his computer logic. He often advises John based on permutations
of the T1000's next move, similar to the way a chess computer decides what move
to make next. Just as the T800 is designed to perform solely as a unemotional
computer, the ‘replican .....

Can Computers Understand?
.... characters and appearing to know the
language, but in reality the man is just following the instructions given to him
( the program). This example serves well to explain how although a computer can
look like it understands a story, it can do no more than "go through the
motions."
Of course such a definitive standpoint on an issue as controversial as
the capacity of an AI to understand will draw many critics. The criticism of
his theory that I find to be the most credible is The Other Mind Re .....

How Technology Effects Modern America
.... that the supply of workers in the [unskilled labor] categories already
exceeds the demand for their services," says L. Mishel, Research Director of
Welfare Reform Network.
In view of these facts, I wonder if these trends are good or bad for society.
"The danger of the information age is that while in the short run it may be
cheaper to replace workers with technology, in the long run it is potentially
self-destructive because there will not be enough purchasing power to grow the
economy," M. B. Zuc .....

A Technical Analysis Of Ergonomics And Human Factors In Modern Flight Deck Design

II. The History Of Human Factors in Cockpit Design
The history of cockpit design can be traced as far back as the first
balloon flights, where a barometer was used to measure altitude. The Wright
brothers incorporated a string attached to the aircraft to indicate slips and
skids (Hawkins, 241). However, the first real efforts towards human factors
implementation in cockpit design began in the early 1930's. During this time,
the United States Postal Service began flying .....

Beam Me Up Scotty: Teleportation

molecular elements.
Some people don't try to think of a scientific answer to it, they just
know that they can move something from point A to point B.
There are many kinds of teleportation, one kind is transferring a
picture of an image to a piece of film in a special camera called a tele-camera,
the teleporter sticks the lens of the camera to hiser fore head and thinks about
the picture as hard as they can, most .....

How Guns Work
.... causes the volume behind the bullet to fill with extremely high pressure
gas. The gas pushes on every surface it encounters, including the bullet in
front of it and the base of the gun barrel behind it. The increase in pressure
caused by the gases causes the bullet to be forced into the barrel hence causing
the bullet to come out the muzzle at very high speeds. Once the bullet is fired,
it remains in motion from its momentum. The momentum will carry the bullet
until it strikes an object or gravity pu .....

apple is blocking the view of an orange behind it, you can just move your
head to one side. The apple seems to "move" out of the way so you can
see the orange or even the back of the apple. If that seems a bit
obvious, just try looking behind something in a regular photograph!
You can't, because the photograph can't reproduce the infinitely complicated
waves of .....

Internal Combustion Engines
.... mixture of air and fuel;
in the latter, high compression raises the temperature of the air in the chamber
and ignites the injected fuel without a spark. The diesel engine is a
compression-ignition engine. This article emphasizes the spark-ignition engine.
The invention and early development of internal-combustion engines are
usually credited to three Germans. Nikolaus Otto patented and built (1876) the
first such engine; Karl Benz built the first automobile to be powered by such an
engine (188 .....

.... state, to emit a second photon of the same frequency, in phase
with and in the same direction as the bombarding photon. This process is
called stimulated emission. The bombarding photon of the emitted photon may
then strike other excited atoms, stimulating further emission of photons, all
of the same frequency and phase. This process produces a sudden burst of
coherent radiation as all the atoms discharge in a rapid chain reaction. The
light beam produces is usually pencil thin and maintains its size .....

Radio: A Form Of Communication
.... of radio had been demonstrated in the early 1800s by such
scientists as Michael Faraday and Joseph Henry. They had individually developed
the theory that a current flowing in one wire could induce (produce) a current
in another wire that was not physically connected to the first.
Hans Christian Oersted had shown in 1820 that a current flowing in a wire sets
up a magnetic field around the wire. If the current is made to change and, in
particular, made to alternate (flow back and forth), the building up .....

Steam Turbines
.... parts of all steam turbines consist of nozzles or jets
through which the steam can flow and expand. Thus, the temperature drops, and
kinetic energy is gained. In addition, there are blades, on which high pressure
steam is exerted. Stationary blades shift the steam onto rotating blades, which
provide power. Also, turbines are equipped with wheels or drums where the
blades are mounted. A shaft for these wheels or drums is also a basic component,
as well as an outer casing that confines the steam .....
