 In biology, evolution, chromosomes, DNA, genetics and the methods of molecular biology are creations of the West.In physics, the science of mechanics and quantum mechanics, relativity, thermodynamics, and statistical mechanics were all developed by Westerners.The discoveries and inventions by Westerners in electromagnetism include Coulomb's law (1785), the first battery (1800), the unity of electricity and magnetism (1820), Biot–Savart law (1820), Ohm's Law (1827), and Maxwell's equations (1871).
