Imagine a world without technology. There would be no
cell phones, computers, cars, internet, concrete or even paper. Almost
everything that we use or find important to our lives would not exist if there
was no evolution to technology. Technology
is very important to a human lifestyle, so that is why I am going to list the
top 5 most important technological advances that I think changed the world
forever.
Number 5 – Cars
The very first type of car was actually a steam
engine attached to a wagon. It was first invented by a man named Nicolas-Joseph
Cugnot in the late 1700’s. The steam engines were heavy so the wagon became
very slow and hard to control. The internal combustion engine changed the way that
cars were to be powered. It would explode the gas into a cylinder and push the
piston down which would turn the wheel. Many people tried to make a car that
would work well and sell well. But people say that the very first person to
invent a modern automobile was Karl Benz; he began to sell the first line of
cars in 1888.
Number 4 – Computers
In 1623, Wilhelm Schickard
invented the very first model of a computer, it was the mechanical calculator,
but all it could do was add, subtract, multiply and divide. Modern computers
were made when Charles Babbage had an idea. He wanted to make a machine that
could do math and be programmed to do different things too. Charles Babbage was
also the first person to make a fully programmable computer; he called it the
Analytical engine. But because Charles Babbage did not have enough money and
kept changing his design, he never built his analytical machine. As time went
on, computers got more popular. And that stands out at the beginning, because
people got very board doing the same thing over and over. They spent their
whole lives writing things down. So a clever man named Herman Hollerith figured
out how to automatically add up information that the Census bureau collected.
Once they combined this with the programming from Charles Babbage, the
computers we all know now was born.
Number 3 – The Telephone
Bell Scot
was the inventor of the telephone, what he wanted to do was find new methods
for people to communicate. He had an interest with hearing and sound, which led
to experiments with sending sounds over telegraph wires. He worked with Thomas
Watson, an expert in mechanics and electricity. During their course of
experiments, Bell and Watson had strung a wire between two reeds such as are
used to play musical instruments. Watson plucked one of the reeds and the sound
carried over the wire to where Bell was working. In February 14 1876, they
completed their invention of the telephone. Only about 20 years ago inventors
made the telephone wireless and everybody suddenly wanted one.
Number 2 – The wheel
Nobody really knows who invented the wheel
but the earliest well dated description of a wheeled vehicle dated back to 3500
- 3350 BC. The idea spread quickly across Eurasia, reaching the Indus Valley by
the 3rd millennium BC. The very first use of the wheeled vehicle was the
chariot, during the second millennium. The oldest known example of a wooden
wheel and its axle were found in 2003 at a Marsh some 20 km from the capital of
Slovenia. The wheel is not only used for transportation, some toys that
included a wheel dated back to 1500 BC. In our modern community we sometimes
use the wheel to generate power or as machines. But now most people use it as a
method for transportation.
And the most important
technological advance (# 1) – Electricity
Electricity was first recognised when
people touched electric fish such as eels. When people got shocked they knew
that electricity could travel along conducting objects. Lighting is one of the
most dramatic effects of electricity and most people realize that it was a part
of nature. At about the 1800’s people started to use electricity to power some
small things. But when electricity was used the most was in the 1900’s. That
time showed the greatest progress of electrical engineering. Basically
everything that we have today was engineered and powered with electricity. 8
Technology has changed our lives forever. If we did
not have technology our life would be very difficult and we would not live as
long. We are very fortunate to have technology and we can only guess what sort
of things could come next. Thanks for listening
