What are the Most Important Technologies?

Five hundred years ago, Leonardo Downs, the inventor of many wonderful inventions, was an expert in photography. His designs include parachutes, life jackets, swimwear, water pumps, lenses, machine guns, airplanes, helicopters, and submarines.

The German astronomer Johannes Kepler was the first to learn to understand and use telescopes and light according to scientific principles. But the amazing thing was that by that time his own eyesight had become so weak that the binoculars were of no use to him. When Newton was asked how he worked on so many discoveries and ideas, he replied. “I think about the day and night.”

The story of Newton and Apple is very famous, but it is based on a half-truth. The real story was, “Newton was sitting in the garden in the evening when the moon was in the sky in the form of a crescent. An apple fell to the ground. So Newton kept thinking, ‘ There is a force, is the same force affecting the moon? “The fact that the apple fell on Newton’s head is not true.

Inventions and discoveries:

Over the past few centuries, countless discoveries and inventions have been made in the world, which has not only raised our standard of living but also helped us to understand the world around us. It is very difficult to categorize these inventions and discoveries in terms of their importance, but we are still mentioning a few such inventions and discoveries here. Which can be called the greatest inventions and discoveries in human history.

Penicillin:

It is the world’s first antibiotic, discovered by Alexander Fleming in 1928 – if it had not been discovered, people would still be dying of a number of diseases, including gastric ulcers, dental diseases, and throat infections.

Mechanical Clock:

The world’s first mechanical clock was invented by a Chinese monk and mathematician I-Hsing in 723 AD, and it allows you to determine the exact time.

Blood Circulation:

The discovery of the circulatory system is one of the most important discoveries in the world of medicine. The first person to fully inform the world about this system was William Harvey, who in 1628 described the circulation of blood and its properties reaching the heart and brain.

Gravity:

Who doesn’t know the law of gravity – The famous mathematician and physicist Isaac Newton discovered gravity while sitting under a tree in 1664. Apples Agra on his head, and this time he explained why things come from top to bottom.

Air Conditioning:

The air conditioning system has existed since ancient times, but the world is only familiar with its modern form. The electric air conditioning unit was invented in 1902 by Willis Carrier, a young engineer from New York.

Electricity:

The invention of electricity revolutionized the world, and the credit for this invention goes to the scientist Michael Freddy. He discovered many electrical systems. Also, the invention of the generator is also Michael’s own feat.

DNA:

Most people think that DNA was discovered by biologists James Watts and Francis Kirk in 1950, but in fact, DNA was first identified in 1860 by a Swiss chemist Friedrich Miescher, and the same discovery led other scientists to provided assistance in conducting research on.

X-Rays:

The German physicist William Conrad discovered the X-ray system in 1895 when he was studying how electric currents undergo extremely low gas pressure. He was awarded the first Nobel Prize in Physics in 1901 for this discovery. Russian chemist Dmitry Mendeleev divided the elements into rows and columns in his Periodic Table. The atomic weight, melting point, and other properties of the distribution elements were arranged in terms of gradual increase or decrease. He later left some boxes blank in the distance table. He predicted three elements that would be discovered and fit into these boxes. Years later, those three elements were discovered (gallium, scandium, and germanium), and their properties were the same as predicted by Mendeleev.
