  • pascal

    pascal
    Full name: Blaise Pascal
    Birth-Death: June 19, 1623 in Clermont-Ferrand, France. Died August 19, 1662 in Paris, France.
    Fame: Invented the hydraulic press and the syringe. He proved hydrostatic pressure doesn't depend on the weight of the fluid but elevation difference.
    Age of fame: 23 years old
    Age of Death: 39 years old
    Extra info: Developed the Treatise on the Arithmetical Triangle, known as Pascal's triangle. Some of his other mathematical formulas are still used.

  • Dalton

    Dalton
    1. John Dalton
    2. Born: 5 Sept 1766 Died: 27 Jul 1844
    3. Dalton came up with the law that states that the total pressure exerted by a mixture of (non-reactive) gases is equal to the sum of the partial pressures exerted by the individual gases, known as Dalton’s Law, or Dalton’s Law of Partial Pressures. However, Dalton’s law isn’t followed exactly by real gases, working more with the ideal gas model. 4.35
    4. 77
    5. 6. He became a teacher at only 12 years old, when he opened his own school.

  • avogardro

    avogardro
    1. Lorenzo Romano Amedeo Carlo Avogadro di Quaregna e di Cerreto
    2. Born : 9 August 1776 Died : 9 July 1856
    3. “Claim to Fame”: Avogadro drew the distinction between the molecule and the atom, and suggested that equal volumes of every gas, when at the same temperature and pressure, contained the same number of molecules. This, Avogadro’s Principle, would later be used to determine molar masses and indirectly, atomic masses.
    4. Age when he made “claim”: 35

  • continued of Avogardro

    1. Age when he died: 79
    2. Interesting point: Avogadro was initially educated in Law, becoming a bachelor of Jurisprudence at the age of 16, and getting his doctorate in Ecclesiastical Law when he was twenty.
