Since the beginning of human life, enormous changes around us have led us on a path of scientific progress, which in turn has benefited humanity in various ways. In each age, man has innovated many things to satisfy his growing needs.

Imagine life in the Stone Age! The primitive ways of life only included the activities of man around the search for food and shelter. They hunted animals for food and used caves for shelter, and animal skins and leaves to cover their bodies. The fire was discovered accidentally when two pieces of rock rubbed against each other, but since then people have started using it for protection and for heating and cooking.

No doubt these seem meaningless to us today, but consider life without these discoveries and inventions. Would you be able to enjoy the same quality of life without them? But the fact is that the emergence of needs led man to explore more.

With the passage of time, the man became aware of other needs that arose around him. After satisfying his basic needs for food and housing, man felt the need to acquire goods that he himself could not produce. This led to the idea of ​​the barter system under which goods were exchanged without the use of money, but a restriction on this mechanism was its limited movement. How far could a man loaded with tons of wheat travel for a few kilos of meat? So the man came up with the idea of ​​the wheel.

The wheel is undoubtedly one of the first and most important mechanical inventions. The invention of the wheel served as a milestone in the history of science because it was a prerequisite for many other inventions. He introduced the idea of ​​the transportation network without which the economy could never have developed. Without it there would be no movement, no cars, no trains, no planes. He shortened distances and gave man the opportunity to explore the world.

The Chinese invented the wheelbarrow, which made use of lever action.

The first use of the wheel for non-transport purposes occurred in the Bronze Age with the invention of the potter’s wheel, first used in Mesopotamia in 3500 BC. Pottery began to be slowly molded in ancient Egypt in about 3000 B.C. C. and around fast several centuries later.

However, as communication was channeled, the rise of the world’s horizons led to the urgent need to express oneself. As the need arose, man took advantage of the use of images and paintings for self-expression, which later developed the concept of writing. Initially, the ancient Romans and Egyptians used different signs and marks to symbolize different meanings. Later, the Phoenicians invented the alphabet in 1600 B.C. C. and then numbers were invented in India in 300 BC. Now people could communicate with each other when they moved from one place to another. But now the form of expression needed a medium to transfer. Verbal communications led to the creation of Languages.

With the need to write evolved the need for a substance on which to write. Initially stones, scrolls and leaves were used, but they were not satisfactory. As time passed, paper was first invented in China and then multiplied in the rest of the world.

Man, man, works and therefore his advances continued. His needs were growing rapidly with regard to such innovations. The wheel of time changed weeks to months and months to years. Now man was capable of producing in massive quantities. As he entered the 17th century, massive inventions and innovations directed his entire life in a different way.

First, the appearance of the steam engine provided a milestone in Europe’s Industrial Revolution. 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 into the cylinder and then condensed it with a stream of cold water. The vacuum created allowed atmospheric pressure to push the piston down.

Later the same idea was further developed to advance steam engine operations. But now the search was for cheap transmission of energy because to what extent could man trust manual behaviors. It was not until 1831 that Michael Faraday demonstrated how electricity could be produced and that in 1873 led to the development of a dynamo capable of long-lasting operation. Electricity was a major factor in the extraordinarily rapid industrialization of the world in the 18th and 19th centuries. Thus, the Industrial Revolution was attributed to the emergence of a number of simultaneous factors, including the steam engine, electricity, and cheap steel, which further accelerated the process of progress.

It was a propitious moment to introduce new ideas. The fundamental principle used in the steam engine and electricity paved the way for scientific block procedures. To enhance communication, the telephone was invented by Alexander Graham Bell in 1876. In 1886, a German, Gotlieb Diameter, built the first gasoline-powered vehicle that made movement easier for man in the form of less time and more comfort. The first television broadcast appeared on the world horizon at London’s Alexander Palace in 1936, further accelerating the process of sharing thoughts and ideas.

The previous great scientific inventions are worth mentioning not only to familiarize yourself with such innovations, but also to interpret the fact that man shapes himself according to his needs. As the need arose, the man came up with new ideas, new thoughts, and forcefully pushed his mind to follow that particular line of action.

Even in the modern age, man has been found to observe the same behavior patterns. Some years ago tuberculosis and cancer were considered as incurable diseases, man did massive research on them and finally found effective solutions.

Until World War I and World War II, the world never experienced any threat to its peace and harmony. However, after these two events, the less developed countries found themselves threatened by the more technologically advanced countries in terms of their defense. This led to the rise of the United Nations Organization, which was developed to promote stable political, economic, and social conditions conducive to peace.

Similarly, the computer was required to manage the process and program the data collected in different ways. The invention of the Internet was ultimately the result of the need to reduce distances and increase fast connectivity.

Today most countries face the dilemma of the energy crisis. Historically, fossil fuels have been the main source of energy supply and have met human energy needs for thousands of years. But now its exhaustion has forced man to use some alternative means to meet the growing demand for energy. The use of hydrogen has been considered the optimal future fuel, since it is the simplest and most abundant element in the universe.

Whether in old age or in the modern age, man has been found to be too efficient to meet his needs and has given numerous examples of this. No matter if it was a political question, a scientific concern or even the daily tasks of life, the man has reacted with a flexible frame of mind to create a path for himself whenever he realized the needs of the. Unsurprisingly, he has succeeded in achieving an alternate source for his need every time, for where there’s a will, there’s a way.
