Biggest Scientific Discoveries In The History Of Mankind | Discovery Of Science | Scientific In Urdu

Over the course of ages, we have made countless discoveries that have improved the quality of our life and helped us to understand the world around us. It is very difficult (if not impossible) to rank the importance of the discoveries we have made, but one thing is for sure – some of them have literally changed our life. From penicillin and the screw pump to X-rays and electricity, here are some Biggest Scientific Discoveries in History of Mankind.

Penicillin

If Alexander Fleming, Scottish scientist, had not discovered penicillin, the first antibiotics, in 1928, we would probably be still dying from things such as stomach ulcers, tooth abcesses, strep throat and scarlet fever, staph infections, lyme disease, leptospirosis etc.

Mechanical Clock

There is certain controversy as to what the first mechanical clock was, but it is usually considered to be the clock created by Chinese monk and mathematician I-Hsing in 723 A.D. This groundbreaking discovery allowed us to quantify time.

Blood Circulation

One of the most important discoveries in medicine, the discovery of blood circulation is credited to the English physician William Harvey who, in 1628, was the first person to completely describe the systemic circulation and properties of blood being pumped to the brain and body by the heart.

Gravity

It is a well-known story – Isaac Newton, famous English mathematician and physicist, discovered gravity after an apple fell on his head in 1664. His discovery explained why things fall down and why the planets revolved around the Sun.

Air Conditioning

Primitive air conditioning systems have existed since the ancient times, but it was not until 1902 when the very first modern electrical air conditioning unit was invented by a young engineer named Willis Carrier in Buffalo, New York.

Electricity

The life-changing discovery of electricity is attributed to the English scientist Michael Faraday. His main discoveries include the principles underlying electromagnetic induction, diamagnetism, and electrolysis. Faraday’s experiments also created the first generator, the forerunner of the huge generators that produce our electricity.

DNA

Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950’s, but in fact, it was first identified in the late 1860’s by Swiss chemist Friedrich Miescher. Then, in the decades following Miescher’s discovery, other scientists carried out many research studies that helped us understand how organisms pass on their genes and how the workings of cells are governed.

X-Rays

German physicist Wilhelm Conrad Rontgen discovered X-rays in 1895 when he was studying the phenomena accompanying the passage of an electric current through a gas of extremely low pressure. For this ground-breaking discovery, Roentgen was awarded the first-ever Nobel Prize in Physics in 1901.
