    Democritus

    Democritus
    Democritus was a central figure in the development of the atomic theory of the universe. He theorized that all material bodies are made up of indivisibly small atoms.

  • Robert Boyle

    discovered that the volume of a gas decreases with increasing pressure and vice versa the famous Boyle's law.

  • John dalton

    John Dalton was an English chemist, physicist, and meteorologist, best known for introducing the atomic theory into chemistry and for his work on human optics.

  • amedeo Avogadro

    Avogadro correctly hypothesized that equal volumes of gases, at the same temperature and pressure, contain equal numbers of molecules

  • Dmitri Mendeleev

    Dmitri Mendeleev devised the periodic classification of the chemical elements, in which the elements were arranged in order of increasing atomic weight.

  • THE CURIES

    Pierre and Marie Curie made history not only in that respect, but also because their scientific teamwork led to the discovery of radioactivity and two new elements in the periodic table.

  • Albert einstein

    Albert Einstein was a famous physicist. His research spanned from quantum mechanics to theories about gravity and motion.

  • jj thompson

    On his return from America, he achieved the most brilliant work of his life an original study of cathode rays culminating in the discovery of the electron.

  • Ernest Rutherford

    Ernest Rutherford demonstrated that there were at least two distinct types of radiation ,alpha radiation and beta radiation. He discovered that radioactive preparations gave rise to the formation of gases.

  • Henry g.j. mosely

    Henry Moseley collected the x-ray spectra of a variety of elements and found that the frequency of x-ray radiation has a precise mathematical relationship to an element's atomic number.

  • Robert millikan

    Robert Millikan was an American, Nobel Prize-winning physicist, credited with the discovering the value for electron charge.

  • Antone lavoisier

    Antoine Lavoisier, a meticulous experimenter, revolutionized chemistry. He established the law of conservation of mass, determined that combustion and respiration are caused by chemical reactions with what he named oxygen.

  • Werner Heisenberg

    Heisenberg's name will always be associated with his theory of quantum mechanics.For this theory and the applications of it which resulted especially in the discovery of allotropic forms of hydrogen.

  • James Chadwich

    Chadwick is best known for his discovery of the neutron in 1932. In 1941, he wrote the final draft of the MAUD Report, which inspired the U.S. government to begin serious atom bomb research efforts.

  • erwin Schrödinger

    Austrian physicist Erwin Schrödinger was a noted theoretical physicist and scholar who came up with a groundbreaking wave equation for electron movements.
