10 Most Important Discoveries of The 20th Century

Have a look at the 10 most important scientific discoveries of the 20th century including medical and Physics discoveries.

Research and development in the 20 century has brought in many areas, some literally groundbreaking discoveries that could significantly affect the direction and herald the next evolution of mankind. 21st CENTURY compiling and submitting their ranking.

1st Penicillin: 
The discovery of the first effective antibiotic, which ultimately could save millions of lives around the itch occurred in 1928, actually a complete accident. Scottish bacteriologist Alexander Fleming, who worked in a London hospital Wed Mary on the research use of biological agents in the laboratory, forgot before leaving for vacation to clean one Petri dish in which they reclaimed the staphylococcal bacteria

2nd Telegraphy: 
The invention of wireless telegraphy, it invents primarily an Italian scientist Marconi. Then Marconi was inspired by his own experiments that stated by several years before by a German physicist Heinrich Hertz, who demonstrated the existence of invisible electromagnetic waves that move the air speed of light. 

3rd Atom bomb: 
The discovery that a nuclear fission emits large amounts of energy, led to the production of nuclear weapons. The construction of the first atomic bomb worked in U.S. labs in Los Angels, the best scientists, such as Albert Einstein.

4th Structure of DNA:
In 1928 English bacteriologist Frederick found Griffiths, the nature of genes is a chemical substance which was later identified as deoxyribonucleic acid (DNA) and has been shown that the genetic information determining the uniqueness of every living organism is encoded in it now. To discover the structure of this information and the creation of the model in the form of a double helix is the trio of scientists: James Watson, Francis Crick and Maurice Wilkins. 

 5th Contraceptive pill:
The early fifties of the last century (1951) managed to U.S. chemist Carl Jurassic produce synthetic hormone by norethisterone, which became the basis for the contraceptive pill. First came up with the idea of hormonal contraception early twenties Austrian Professor Ludwig, based on the fact that during pregnancy a woman not become pregnant again because her ovaries produce the hormone progesterone

6th Motorized aircraft:
The first operational aircraft engine in the world constructed in 1903 by Americans, brothers Wilbur and Orville Wright. Their Flyer was built of wood and materials, reinforced with wire and equipped with two propellers push that engine of its own production, water cooled in line with four cylinders.

    Reading this reminded me of a story I heard about the man who first identified a practical way of creating an atomic bomb. He was an ardent pacifist and before he told anyone else, he seriously considered killing him self so it would not be unleased on the world. When he was told about the bombing of Hiroshima he said he wished he had.
