7 Scientists are not famous, who have changed the world.

1. Joseph Lister (1827-1912)

 

While working as a surgeon at the Glasgow Royal Infirmary, Lister tried to solve the problem of wound infection, which killed 45% -50% of all cases of amputation. After studying some of the work of Louis Pasteur, and read the paper on the use of carbolic acid in sewage treatment, Lister began treating patients injured by carbolic acid. He forced surgeons to wash their hands before and after treatment with a solution of carbolic acid, as well as surgical equipment thoroughly with the solution, thereby realizing a revolution in hospital hygiene. Regarded as the father of antiseptic, Lister discovery has saved countless lives around the world, and is one of the biggest breakthroughs in medical history.

2. John Bardeen (1908-1991) 

A physicist electrical engineer from the United States, John Bardeen was one of the few people to win two Nobel prizes. In 1956, with two colleagues, he developed a power transistor, a development that has facilitated the development of any electronic device that is used in the modern world. His discovery of superconductivity in 1972 that has allowed the use of CAT and MRI scans in medicine. While having this revolutionary breakthrough, Bardeen virtually unknown outside the scientific community. However, his legacy has changed the world beyond expectations.

3. Karl Landsteiner (1868-1943) 

 

Austria dokter yang melalui pelatihan, Landsteiner memainkan peran integral dalam identifikasi golongan darah. Dia menunjukkan efek dari bencana jika salah jenis transfusi darah, serta menunjukkan sifat turun-temurun dari jenis darah yang sejak itu telah digunakan sebagai metode untuk menunjukkan keturunan. Dia juga memberikan kontribusi pada identifikasi virus polio, dan membuat banyak sumbangan imunologi, histologi dan anatomi. Meskipun warisan terbesar, adalah dalam memahami golongan darah yang berbeda untuk transfusi darah, bagaimanapun, berperan penting dalam meningkatkan tingkat ketahanan hidup di operasi.
 
4. James Clerk Maxwell (1831-1879)
 

Recognized by some as the father of modern physics, James Clerk Maxwell was a very influential figure in the field of electricity, thermodynamics, photography, nuclear energy, and others. Invention of the electromagnetic spectrum that affect the development of television, radio, microwave, and assist in the development of radio and infrared telescopes. Equations on electromagnetic field is very important for the theory of special relativity, by Albert Einstein. He also produced the first color photograph, picture tartan ribbon. His work truly marks a departure from the work of another great scientist Isaac Newton, and help to inform the science behind many of the technological developments of modern times.
 
5. Leó Szilárd (1898-1964) 

 

















 

 

Perhaps one of the lesser known collaborators on the Manhattan Project was Szilárd who plays on the idea of ​​a nuclear chain reaction, a process to develop an atomic bomb. He is also the person who initiated the Manhattan Project, that by writing to President Roosevelt to the urgency of developing a weapon is a weapon, because he believed the Germans researching something similar. Although he was disgusted at the use of violence, but Szilárd has contributed to the early development of the nuclear age, and it has changed the world dramatically.

 

6. Fritz Haber (1868-1934)

 

Fritz Haber was a German chemist who unmasked the good work wonders and ferocity of a science that is not revealed. Haber listed his name in the industrial synthesis of ammonia, an important component of fertilizer in modern agriculture. This has helped in intensive food production that has become a hallmark of the modern world, and in turn allows the growth of a large population from the 20th century. He was heavily involved in the development of chemical weapons such as chlorine gas to Germany in World War I, and he was nicknamed by some as the father of chemical warfare. Haber's work helped the development of cyanide gas, which is used by the Nazis to carry out some of the worst atrocities in human history.
 7. Thomas Midgley (1889-1944)

 


















 

Thomas Midgley is a person who has made major contributions to the modern world. Unfortunately, not a positive contribution. First, Midgley find addictive to make gasoline stop the effect of "knocking" on the engine. However, it also raises issues of global health. Subsequently, he was a role in the development of CFC, one of the most damaging compounds in our atmosphere today, and a major contributor to global warming.

It has been recognized that Midgley "had more impact on the atmosphere than any other organism in history." It's sad for him, but nevertheless useful to mankind. He contracted polio which made ​​him unable to move from his bed, and after designing an elaborate pulley system to help him get out of bed, he accidentally caught in the rope and strangle himself.
