Aristotle
Aristotle provided us with knowledge of natural science including Physics, which gives a vast amount of information on astronomy, meteorology, plants, and animals. -

Democritus
Democritus discovered that matter was made of small particles , which he called atoms, floating in a void. -
Antoine Lavoisier
AFrench nobleman in the histories of chemistry and biology.He named both oxygen (1778) and hydrogen (1783) -
John Dalton
While studying the nature and chemical makeup of air in the early 1800s, he was the first scientist to explain the behavior of atoms in terms of the measurement of weight. -
Joseph Louis Proust
Proust’s largest accomplishment was creating elements from water. He put hydrogen in science that was disproving Berthollet with the law of definite proportions, which is sometimes also known as Proust's Law. -
Michael Faraday
English scientist who contributed to the fields of electromagnetism and electrochemistry. His main discoveries include those of electromagnetic induction, diamagnetism and electrolysis. -
Marie and Pierre Curie
Marie and Pierre Curie discovered the new element that came to be called “radium,” aa important element in chemistry and physics. -
Henri Becquerel
Antoine Henri Becquerel was conducting an experiment which started with the exposure of a uranium-bearing crystal to sunlight. Once the crystal sat in the sunshine for some time, he put it on a photographic plate. As he had anticipated, the crystal produced its image on the plate. Becquerel realized that the absorbed energy of the sun was being released by the uranium in the form of x-rays. (Radioactivity) -
J.J. Thomson
Discovery of the electron in 1897 showed us that an atom can be split into smaller parts and pieces. -
Ernest Rutheford
Through the Gold Foil Experiment he discovered that when Gold Atoms were deflected off of tin foil that some of them must have bounced because of a dense center in the atoms or known as the nucleus. Basically, in turn, he discovered the nucleus. -
Max Planck
German theoretical physicist Max Planck discovered an equation that explained the results of these tests. The equation is E=Nhf, with E=energy, N=integer, h=constant, f=frequency. In determining this equation, Planck came up with the constant (h), which is now known as "Planck's constant. ( Quantum ) -
Albert Einstein
Albert Einstein published a number of scientific works that changed physics forever. The best known of these,now known as the Special Theory of Relativity, established Einstein and led to his General Theory of Relativity, one of the starting points of modern physics. -
Robert Millikan
Robert Millikan was an American experimental physicist, and Nobel laureate in physics for his measurement of the charge on the electron and for his work on the photoelectric effect -
Neils Bohr
Very important man, Neils Bohr, discovered that electrons in atoms are arranged according to the energy levels. -
James Chadwick
Chadwick made a fundamental discovery in nuclear science: he proved the existence of neutrons - elementary particles devoid of any electrical charge
