Science has been of great help to the people. Below are some of the great things that were discovered and invented by famous people around the world.

Anaesthesia

With the discovery “anaesthesia”, people conquered pain. It made some of the most dangerous medical operations to be possible without further hurting the patient. The term was coined by Oliver Wendell Holmes, Sr. in the year 1846. The original definition of this term is “the blockage of sensation” but could also be defined as, “reversible lack of awareness”. Actually, anaesthesia was already used in the pre-historic times. Even in the year 4200 B.C., opium poppy was collected to make it as a herbal anesthesia.

Carbon dating

This method is used to accurately identify the age of a certain object. This was developed by Willard Libby and his colleagues at the University of Chicago in the year 1949. He received a Nobel Price in Chemistry for his work and achievements. Although,a more accurate figure was found out, most scientist prefer to use the Libby figure to avoid inconsistencies of the previous informations published.

Blood Circulation System

It was in the year 1242 that an Arabian physician accurately described the human circulatory system. Although some of the earliest people already had the thought of the system, it was in the year 1628 that  William Harvey announced that the discovery of the human circulatory system was his. He performed several tests and wrote an influential book, and these convinced the medical world to believe in the genuineness of the discovery. Harvey was not able to identify the capillary system connecting arteries and veins; these were later described by Marcello Malpighi.

Deoxyribonucleic acid

The discovery of the DNA was made by the Swiss physician Friedrich Miescher. It was first called as a “nuclein” because it resides in the nuclei of a cell. The first correct image of the DNA was made as a suggestion by James D. Watson and Francis Crick based on image diffraction done by Rosalind Franklin. DNA is the blue print of a person because it holds the instructions how to build up some of the components of the other cells.

Australopithecus

This is known to be the very fist human to exist. The skull was actually discovered by an unknown South African but further investigations were made by Raymond Dart. The fossil was recorded to be 3.7 million years ago. The brains of most species of Australopithecus were roughly 35% of the size of that of a modern human brain. Most species of Australopithecus were diminutive and gracile, usually standing no more than 1.2 and 1.4 m (approx. 4 to 4.5 feet) tall. Actually, the skull found by the South African native was thought be the skull of an ape, but after seeing that the spinal column was connected below the skull and not at the back, it was later concluded that it should be a skull of a man and not of an ape.

Electricity

Although Ancient Egypt already had the idea of electricity, it was in the 18th century that a man named Benjamin Franklin made an extensive research about electricity. With his experiment using a kite, it was proven that the natural phenomena which was lightning was really an electricity. In the 19th century, the development of electricity was very rapid, and some very notable people who contributed to that were Nikola Tesla, Thomas Edison, George Westinghouse, Ernst Werner von Siemens. The electricity that was just scientific curiosity before became an essential tool of today.

Fingerprint

Although some of the ancient places already used the method of fingerprinting, it did not became known to men until in 1823 that a Czech, Jan Evangelista Purkinje, noticed that every man’s fingerprint differed. Fingerprint is very essential because it detects the identity of the person. In any mysterious cases, fingerprints are the things that could lead to the suspect.

Heredity

The principle of heredity was first propounded by Aristotle. Heredity was defined as “the passing of traits to offspring”. The ancient scientific discovery of heredity answered the questions of most people. Some people before and even now ask why some of the values and attitudes are being passed off to the child, and so the principle of heredity is now available to answer the questions.

Insulin

It was Paul Langerhans in the year 1869 who noticed insulin when he was dealing with the pancreas under the microscope. The insulin was an effective way of eliminating the signs of diabetes. The very fist person who has been injected by this was Leonard Thompson who was a 14 year old diabetic. It was first unsuccessful, but after many days of comprehensive study and modification, the formula was perfected and then was injected to Leonard.

Light Bulb

The modern recommended thing to be used is the ‘fluorescent bulb’ because it can save energy, but the scientific invention that paved way to the making of the fluorescent bulb was the very first incandescent light bulb. It was first invented by Humphry Davy for noncommercial use but was not that successful. The most credited inventor was Thomas Edison when he modified it and made it into commercial use.

Computer

Who could even live without their computers. Nowadays, people often use computers for their projects and other important businesses. As for as Triond writers, we do need our computers if I’m not mistaken. It is not actually known who deviced the earliest computer because the definition of the term differs in each places.

Internet

According to Wikipedia, “The Internet is a global system of interconnected computer networks that interchange data by packet switching using the standardized Internet Protocol Suite (TCP/IP).” Although there are some things that could harm us inside the internet, there are also some things that could be of benefit to us. Just like here in Triond, we do use our internet connection to write and earn. Although the internet have existed for decades already, this did not became of public face until the years 1990’s.

Although there have been so many inventions that made history, the inventions and discoveries above really made a difference in the world. If ever there are some things that you would like me to add, never be afraid to state them in the comment box. I will also have a sequel of this article in the next coming days. God Bless You!
