Greatest inventions to change the world (9 form)
There
could not be any development without inventions. Modern world can be called the
world of technology, but the way to this title was rather long. Nowadays there
are numerous laboratories discovering something new on a daily basis, but there
are some inventions that date back centuries, but are still the core of the
modern science. Almost all of contemporary discoveries have been based on
previous inventions, so we should give credit to those talented inventors, who
laid the foundation for our comfort. Let us remember the most crucial
inventions and their creators, who paved the way to our easy-going life.
A
wheel is one of the most ancient people’s inventions. It is the thing that lets
us move nowadays, but became a revolt in manufacturing hundreds of years ago.
It is supposed that a wheel was discovered 3,000 years ago by potters and
helped to carry different goods. It was a real boost when the wheel was
enhanced to the extent that it became a part of the vehicle. The invention of
the wheel is a concept that lay grounds for many other inventions we can not
live without.
A
steam engine invention can be called a key to our modern transportation and
industries. Though we use more developed engines nowadays, all of them work in
the same way – burning fuel is conversed into kinetic energy. James Watt is
considered to be a leading inventor of a steam engine, but there are numerous
successors, who were improving it decade after decade. This invention had a
dramatic impact on the world industry allowing factories to be free from water
power, developing coal industry, increasing the speed of trains and becoming a
core of modern transportation system.
Electric
light is another crucial invention that influenced the development of the
mankind. Thomas Edison managed to invent a light bulb lasting for 1,500 hours,
while William David Coolidge is credited as the inventor of incandescent bulb
familiar to us.
A
telephone is one more revolutionary idea for people’s communication. Though the
idea of it is rather simple, it took many years to realize it in real life.
Michael Faraday, Johann Reis, Alexander Graham Bell have worked on the
telephone equipment and the last inventor managed to reach his target and even
founded the first telephone company. This company is also regarded to have
developed the first mobile phones for police and later set the pace for cells
development.
The
television set has greatly changed the world with its appearance. Though all
people think that black and white TV is considered to be the first public
television, colour moving images did not follow behind and appeared before full
functionality of black-and-white TV sets. Their appearance changed the way of
life of many people, who changed their habits forever in favour of interesting
and exciting TV programs.
It
is impossible not to remember a
refrigerator as one of really impressive inventions.
Though its appearance is connected with many names, the concept of a refrigerator originates
from 1800s. The greatness of this invention implies the ability to prolong life
of many products in cold environment and it has given a
stimulus for the
development of food production industry on a new higher level.
It
goes without saying that modern people can’t imagine their life without
computers and the Internet. Being a commonplace in most of
contemporary homes today, it is quite difficult to imagine that the first
computer appeared only about 50 years ago and now it has changed completely.
Based on two important innovations such as the integrated circuit (интегральная схема) and the microprocessor the computer began performing logical
calculations and surprised people with its intelligence. The first desktop
computer for everyday use was manufactured in 1974 and its popularity was
enormous. Apple computers by Stephen Wozniack and Steven Jobs got the first
world’s computer system. The next step in computer development was IBM PC with
a more powerful and faster processor. Gradually, the competition between
companies resulted in a constant development of the machine for this
revolutionary invention not to lose its popularity.
No
doubt that the Internet is one of the most recent and essential inventions of
the mankind. This network aims at connection of thousands of other smaller
networks that create a global network. Created by the
Americans in 1973 it was initially used for
connection of University networks and spread to Europe only in 1989. What is
the Internet exactly? It is an
interconnection between various networks established
across optical fibres, telephone lines and radio links. Each
particular machine has a unique address. The necessary data travels from one
gateway to another till its destination machine. The Internet is an
indispensable helper with the wealth of diverse
information available at the click of a mouse and provided thousands of
different opportunities to all people.
These are only some of the greatest world’s inventions worth mentioning. They have determined the way of humanity development and set the grounds for further innovations.
