Filipino Scientists, Inventors and Researchers
Eduardo Quisumbing (1895 – 1986)
Was a noted expert in the medicinal plants of the Philippines
A graduate of the Massachusetts Institute of Technology invented the videophone and developed the Zara Effect or Electrical Kinetic Resistance.
Gregorio Zara(1902 - 1978)
The first Asian to have entered the prestigious Harvard University's School of Medicine, is also credited for her studies that led to the invention of incubator and jaundice relieving device.
Fe del Mundo(1911 – 2011)
Pioneered Philippine psychology and made the first intensive study of Myxophyceae or blue-green algae
Gregario Velasquez (1901-1989)
Noted researcher in the chemistry of natural products
Alfredo Santos(1905 – 1990)
Foreign Scientists and Their Contribution to the
Field of Chemistry
Amadeo Avogadro(1776-1856)
He interpreted Gay-Lussac’s findings and later formulated Avogadro’s law which states that at a given temperature and pressure, the same volume of any two gases contain an equal number of molecules.
He was the first scientists to measure the relationship between pressure and volume of gases. He found out that the volume of certain amount if dry gas held at constant temperature is inversely proportional to the pressure exerted by the gas
Robert Boyle(1627-1691)
She discovered the elements polonium and radium. She was the first woman to receive the Noble Prize in chemistry and the first person to share in two Nobel prizes.
Marie Skiodowska Curie(1867 – 1934)
According to him, the pressure exerted by a mixture of non-reacting gases is the sum of partial pressures that each gas in the mixture exerts individually. He also postulated the existence of a different kind of atom for each element.
John Dalton(1766-1844)
He conducted an experiment that results to the idea that an atom has a nucleus. He found out that most of an atom must consist of space through which particles could move readily.
Ernest Rutherford(1871– 1937)
