In History
  • -460 BCE

    Democritus

    Democritus
    Democritus was an Ancient Greek pre-Socratic philosopher primarily remembered today for his formulation of an atomic theory of the universe. Democritus was born in Abdera, Thrace, around 460 BC, although there are disagreements about the exact year.
  • -428 BCE

    Plato

    Plato
    was an Athenian philosopher during the Classical period in Ancient Greece, founder of the Platonist school of thought, and the Academy, the first institution of higher learning in the Western world.
    He is widely considered the pivotal figure in the history of Ancient Greek and Western philosophy, along with his teacher, Socrates, and his most famous student, Aristotle.
  • -385 BCE

    aristotle

    aristotle
    Aristotle was a Greek philosopher and polymath during the Classical period in Ancient Greece. Taught by Plato, he was the founder of the Lyceum, the Peripatetic school of philosophy, and the Aristotelian tradition
  • robert boyle

    robert boyle
    Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method. He is best known for Boyle's law, which describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system.
  • John Dalton

    John Dalton
    He is best known for introducing the atomic theory into chemistry, and for his research into color blindness, sometimes referred to as Daltonism in his honor.
  • lavoisier

    lavoisier
    It is generally accepted that Lavoisier's great accomplishments in chemistry stem largely from his changing the science from a qualitative to a quantitative one. Lavoisier is most noted for his discovery of the role oxygen plays in combustion. He recognized and named oxygen (1778) and hydrogen (1783), and opposed the phlogiston theory.
  • Dmetri Mendeleev

    Dmetri Mendeleev
    Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He is best remembered for formulating the Periodic Law and creating a farsighted version of the periodic table of elements
  • Robert millikan

    Robert millikan
    Robert Andrews Millikan was an American experimental physicist honored with the Nobel Prize for Physics in 1923 for the measurement of the elementary electric charge and for his work on the photoelectric effect. Millikan graduated from Oberlin College in 1891 and obtained his doctorate at Columbia University in 1895
  • ernust rutherfurd

    ernust rutherfurd
    Ernest Rutherford, 1st Baron Rutherford of Nelson, OM, FRS, HonFRSE was a New Zealand–born British physicist who came to be known as the father of nuclear physics. Encyclopædia Britannica considers him to be the greatest experimentalist since Michael Faraday.
  • Albert Einstein

    Albert Einstein
    he was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).His work is also known for its influence on the philosophy of science He is best known to the general public for his mass–energy equivalence formula E = mc2, which has been dubbed "the world's most famous equation
  • neils bohr

    neils bohr
    Niels Henrik David Bohr was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research.
  • Henery G.J Mosely

    Henery G.J Mosely
    Henry Gwyn Jeffreys Moseley was an English physicist, whose contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley's law in X-ray spectra.
  • J.J Thompson

    J.J Thompson
    Thomson showed that cathode rays were composed of previously unknown negatively charged particles (now called electrons Thomson is also credited with finding the first evidence for isotopes of a stable non-radioactive element in 1913, as part of his exploration into the composition of canal rays (positive ions). His experiments to determine the nature of positively charged particles, he was the first use of mass spectrometry and led to the development of the mass spectrograph
  • Warner Heisenberg

    Warner Heisenberg
    Werner Karl Heisenberg was a German theoretical physicist and one of the key pioneers of quantum mechanics. He published his work in 1925 in a breakthrough paper.
