Birthday of Georg Ohm (1789)

Georg Ohm discovered Ohm's Law — V = IR — through meticulous mathematical experimentation. His 1827 publication was initially rejected and ridiculed by German scientists; a minister of education called it 'a web of naked fancies.' The Royal Society of London recognised his work in 1841 with the Copley Medal. Today V = IR is the most-used equation in electrical engineering. The unit of electrical resistance — the ohm — bears his name. His work exemplifies how mathematical modelling of physical phenomena, though initially resisted, ultimately transforms technology.
