100 X 100 Multiplication

10 scientists who changed the world unknown

The other day surfing the web I noticed a very interesting news in a blog about science I barely know and have made great progress for humanity, this is what I express in my blog started with research to publicly recognize their merit.

speak in terms of modern science inevitably makes us refer to header names for the development of scientific knowledge, such as Copernicus , Galileo Galilei , Karl Marx, Sigmund Freud, Charles Darwin , Isaac Newton, Niels Bohr among many, in a list that would take ten to twenty posts to complete.

However, as science many unfathomable mysteries hidden in the area of \u200b\u200btheoretical mysteries are also present. This time under names that may never have heard, but have been the architects of equally substantial discoveries made by scientists of the previous paragraph. In this unknown list of scientists you list the top ten.

Alhazen - 965-1039

obviously far from the modern development of science, Alhazen (Ibn al-Haytham originally) but was one of those responsible for setting their bases. Made valuable contributions in fields such as mathematics, philosophy, physics, anatomy, astronomy, engineering and medicine. Among his outstanding achievements outstanding work in optics, which served to develop microscopes and telescopes in later periods.

Avicenna - 980-1037

Avicenna was one of the most important Islamic scientists. He worked in medicine, mathematics, logic and geology, and wrote about 450 articles throughout his life. Highlights his work in medicine, and is credited with introducing the method of quarantine and systematic experimentation.

Alfred Russel Wallace - 1823-1913

In the history of science are curious cases like Russel Wallace. Contemporary Charles Darwin, the English naturalist, geographer and independently reached the concept of natural selection, crucial for the theory of evolution. In fact, Darwin himself found the work of Wallace as a masterly summary of his own ideas. However, luck was on the side of Charlie, and while Darwin is known around the world, Wallace is remembered only in specialist circles.

Joseph Lister - 1827-1912

Based on the work of Louis Pasteur, Joseph Lister made a fundamental contribution to the development of medicine in the study of wound infection. Considered the father of antiseptic medicine, Lister introduced fundamental concepts of occupational health hospital, returning to safer facilities.

James Clerk Maxwell - 1831-1879

Perhaps Maxwell is the most prominent scientist in this list. His work in photography, thermodynamics, nuclear energy and power allowed him to discover the electromagnetic spectrum, crucial discovery for the development of television, radio and microwaves. In addition, Maxwell is the author the first color photograph of the whole story.

Fritz Haber - 1868-1934

Haber's name is quite ambiguous, since their work, although fundamental and fascinating, is responsible for innumerable troubles that beset humanity. While allowing for increased fertilizer studied the increase of agricultural production, jobs in chemistry have allowed the development of chemical weapons used by the Nazis to commit more of their atrocities. In fact, Fritz Haber is a name normally associated with chemical warfare.

Karl Landsteiner

- 1868-1943

Typology highlighted, Landsteiner made a crucial work for medicine in the identification of blood groups. To him we owe the knowledge of the terrible consequences of transferring a wrong blood type, and also notable contributions in histology, anatomy and immunology, highlighting for example the identification of the polio virus.

Thomas Midgley

1889-1944 Midgley's case this is again a fatal case in science. He was the one who inserted the lead to oil running cars, creating a huge impact on the environment clean, and if not enough he is responsible for the development of CFCs, one of the most destructive compounds in the atmosphere today.

John Bardeen - 1908-1991

American Physicist and electrical engineer, Bardeen is among the few scientists who have won two Nobel prizes. He was the developer of the transistor electrical This allowed the creation of almost every electronic device today, while also did important work on superconductivity, allowing subsequent development work with MRI.

Tim Berners-Lee - 1955-Present

finally talked on the plane today, to refer to Tim Berners-Lee. Thanks to him we can use the Internet, as we are in presence of its discoverer. Working for CERN (the same ones who developed the LHC), Berners-Lee but decided not to patent his discovery, leaving as a legacy for humanity. Thanks, Tim.
