Today is the birthday of Guillaume Amontons, born in 1663, he invented a new hygrometer in 1687, and improved Galileo’s thermometer in 1695, He should be more famous for Amonton’s Law. Everyone talks about Boyle’s Law and Charles’ Law but fail to mention Amonton’s Law, He said that the pressure of a gas increases with increased temperature. He also said in 1702 that if the temperature dropped enough, there would be no pressure, thus an absolute zero. This concept was made known by Lord Kelvin in 1848.
Today is also the birthday of Michel Chevreul, born in 1786, he was a chemist who discovered margaric acid and designed an early form of soap made from animal fat and salt, he died in 1889 at the age of 102.
Hermann von Helmholtz, born in 1894, he discovered the principle of conservation of energy while working on muscle metabolism, he invented the opthalmoscope for observation of the inside of the eye, he wrote several theorms on the vortex dynamics of fluids, he wrote the Helmholtz equation for electromagnetism, and did many other things, he died in 1894 at age 73.
Bernard Lovell, born in 1913, was a radio astronomer, he died in 2012 at age 98.
David Politzer, born in 1949 received the Nobel Prize in Physics for the discovery of asymptotic freedom in quantum chromodynamics.

Today is the birthday of Jacobus Henricus Van’t Hoff, born in 1852, He was the first winner of the Nobel Prize in Chemistry. He accounted for the optical activity in carbon compounds by assuming the bonds were directed to the corners of a regular tetrahedron. He also made contributions in kinetics, equilibrium and osmotic pressure. He died in 1911 at age 58
Ernest Rutherford, born in 1871 is famous for his gold foil experiment and the hypothesis of a nucleus in the atom. He died in 1937 at age 66.
Theodor Svedberg, born 1884, developed analytical ultracentrifugation to separate proteins from one another, he died in 1971 at age 86.
Edward Purcell, born 1912 discovered nuclear magnetic resonance in liquids and solids, he also proposed the Scallop Theorm to explain aquatic motion at low Reynolds numbers in Newtonian fluids, he died in 1997 at age 84.
Lajos Kisfaludy, born in 1924 introduced the concept of protective groups in peptide synthesis, nearly 80 medicines were synthesized using this technique, he died in 1988 at age 64.
