Biot–Savart law
In mathematics, calculus, statistics, logic, vectors, tensors and complex analysis, group theory, abstract algebra and topology were developed by Westerners. 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). The atom, nucleus, electron, neutron and proton were all unveiled by Westerners.
