Famous Scientists is devoted to acknowledging the movers and shakers throughout history who advanced our world society for the common good. As a website devoted to famous scientists, the purpose here is to both enlighten and entertain.


There are a very large number of famous scientists in history. If a roster of all such famous scientists were to be compiled,

Emil Fisher1852 - 1919Some of his works are: synthesis of glucose, fructose, mannose starting with glycerol, and establishing structures for the 16 stereoisomers of the aldohexoses with glucose as the most prominent member.
Paul Dirac1902 - 1984He received a Nobel prize in 1933 for the work on anti-particles. The "Dirac equation" was a version of the Schrodinger's equation.
Archimedes287 - 212 BCHis major achievements are "The Archimedes principle in hydrostatics", the Archimedes screw and the relation between the surface and volume of a sphere and the circumscribing cylinder.

Alexander Graham Bell1847 - 1922He is the inventor of the telephone and the metal detector.
Chandrasekhara Venkata Raman1888 - 1970He developed the Raman spectroscopy that provides information regarding the molecular structure.
Ernest Rutherford1871 - 1937He developed atomic theory in 1911 and classified forms of radiation.
Joseph John Thomson1856 - 1940He received the Nobel prize for Physics in 1907 and developed the mass spectrograph.
William Ramsay1852 - 1916He independently discovered Helium and shared the discovery or Argon, Krypton and Xenon.
Alfred Nobel1833 - 1896He was a chemist, engineer, innovator, and armaments manufacturer. He is also the inventor of dynamite. He established a fund for the yearly Nobel prize in the areas of chemistry, physics, literature, international peace and medicine.
William Thompson1775 - 1833He derived the second law of thermodynamics and proposed the Kelvin temperature scale.
James Prescott Joule1818 - 1889One determines the rate at which heat is produced by an electric current by using Joule's law.
Julius Robert von Mayer1814 - 1878Along with James Joule, he discovered the first law of thermodynamics.
Henry Bessemer1813 - 1898He invented an economical steel-making procedure that burnt off impurities.
Robert Bunsen1811 - 1899He developed the spectroscope and discovered Cesium and Rubidium.
Thomas Graham1805 - 1869He developed a technique to separate crystalloids from colloids, which is called "dialysis".
Michael Faraday1791 - 1867He stated the laws of electrolysis in 1833.
Johann Wolfgang Dobereiner1780 - 1849He determined the relation between elements and their atomic weight.
Amedeo Avogadro1776 - 1856He concluded that equal volumes of gases at similar conditions of temperature and pressure have the same number of molecules.

ENDANGERD SPECIES IN THE PHILIPPINES

     



The Philippines is revered as a megadiversity country since it houses an astounding multitude of species, most of which are endemic to the tropical country. However, many species are dwindling in number mainly due to anthropogenic activities and habitat degradation. Here is a list of Philippine species which are already classified by the IUCN
