Necessity is the Mother of Invention

Since the beginning of human life, the great changes that surround us have led us to the path of scientific progress, and have benefited mankind in many ways. Throughout time, man has developed many things in order to meet his rising needs.

Imagine life in the Stone Age! A primitive way of life consists of human activities that revolve around searching for food and shelter. They hunt animals for food, and use holes as shelter, animal skins and leaves to cover themselves. Fire was discovered accidentally when two pieces of rock collided, but since then people started using it for protection and heating and cooking purposes.

No doubt, these seem useless to us today, but imagine life without these discoveries and inventions. Would you be able to enjoy the same quality of life without them? But the truth is that the appearance of materials that make people explore more.

As time passes, people become aware of other needs that arise around them. After providing the basic needs of food and shelter, man feels the need to buy goods, which he himself cannot produce. This led to the idea of ​​a business system under which goods are exchanged without the use of money, but the obstacle to this mechanism is its limited mobility. How far can a man walk, carrying a ton of wheat for a kilogram of meat? And people came up with the idea of ​​the wheel.

The wheel is undoubtedly one of the oldest and most important mechanical devices. The invention of the wheel will remain as a milestone in the history of science because it was an important precursor for many other inventions. He introduced the concept of transportation network without which the economy could not have developed. Without it there would be no transportation, no cars, no trains, and no airplanes. It reduces distances and provides people with the opportunity to explore the world.

The Kannada invented the wheel, which made use of a lever.

The first non-transportation use of wheels came in the Bronze Age with the invention of the Potters’ wheel, first used in Mesopotamia in 3500BC. Pottery began to be shaped on a slow wheel in ancient Egypt around 3000BC and on a fast wheel several centuries later.

However, as communication spreads, worldviews lead to a need for self-talk. As the need arose, people used pictures and images to show themselves, this eventually led to the idea of ​​a book. In the beginning, the ancient Romans and Egyptians used different signs and symbols to express different meanings. Then the Phoenicians invented the alphabet in 1600 BC, and then they made a number interpretation in India in 300 BC. Now people are able to communicate with each other when they move from one place to another. But now the method of expression needs a medium to live. Verbal interactions lead to the creation of languages.

With the need for writing comes the need for something to write on. Rocks, parchments and leaves were first used but were unsatisfactory. With the world of paper time we were first made in China and later capital in the rest of the world.

Mankind’s oeuvres and thus its progress continue. Your needs are growing rapidly thanks to such innovations. The wheel of time turns weeks into months and months into years. Now people are able to produce in large quantities. As he entered the 17th century great inventions and innovations directed his whole life in a different direction.

First the appearance of the steam engine provided a landmark in the Industrial Revolution of Europe. The first steam engine was built by an engineer, Thomas Newcomen in 1705 to improve the pumping equipment used to remove seepage in tin and copper mines. He put steam in the cylinder and sealed it with a spray of cold water. The vacuum created allows atmospheric pressure to push the piston down.

Later the same idea was developed even further to advance the functions of the steam engine. But now there is a search for cheap energy transfer because how can people rely on manual behaviors. In 1831 Michael Faraday demonstrated how electricity can be produced and in 1873 he developed a dynamo that could work for a long time. Electricity was a major factor in the world’s incredibly rapid industrialization in the 18th and 19th centuries. Thus the Industrial Revolution is attributed to the emergence of a number of simultaneous factors, which include the steam engine, electricity and cheap steel, which also accelerate the process of improvement.

It is an exciting time to introduce novel ideas. The basic principle used in the steam engine and electricity paved the way for the principles in the science block. To increase communication, the telephone was invented by Alexander Graham Bell in 1876. In 1886 a German, Gotlieb Diameter made the first oil-powered car which made it easier to transport people in a shorter and more comfortable way. The first TV broadcast appeared on the world scene at Alexander Palace, London, in 1936 which also increased the process of exchanging ideas and ideas.

The above great scientific inventions are worth mentioning not to make you familiar with such innovations but to interpret the fact that how man knows himself is in accordance with his needs. As the need arises, people come up with new ideas, new thoughts and forcefully press their heart to work on that particular line of action.

Even in modern times, people are seen to observe the same behavioral patterns. A few years ago TB and cancer were considered as incurable diseases, people did great research on them and finally developed effective solutions.

Until the First and Second World Wars, the world did not experience any threat to its peace and unity. However after these two events, underdeveloped countries are threatened by technologically advanced countries regarding their security. This led to the emergence of the United Nations, which was developed to promote political stability, economic and social conditions conducive to peace.

Similarly, we need a computer to process and organize the data collected in different forms. The invention of the Internet is the result of the need to reduce distances and increase the speed of connection.

Today many countries are facing the problem of energy crisis. Historically fossil fuels have been the main source of energy supply and have served people’s energy needs for thousands of years. But now their decline has forced people to use alternative methods to meet the growing energy demands. The use of hydrogen has been considered as the best fuel of the future because it is the simplest and most abundant material in the world.

Whether it is the old age or the modern era, man has found it to be more effective in satisfying his needs and has set many examples. Regardless of whether it is a political issue, a scientific concern or even the daily activities of human life, people have a tendency to change to create a way for themselves whenever they find their needs. Unsurprisingly you have been successful in achieving an alternative source for your need every time as wherever love is in a way.
