Today we remember two great physicists #JohannSchweigger (for birthday) and #PyotrKapitsa (for death anniversary) --
Johann Salomo Christoph Schweigger invented the #galvanometer (1820), a device to measure the strength of an electric current. He developed the principle from #Oersted's experiment (1819) which showed that current in a wire will deflect a compass needle. He named this instrument a “galvanometer” in honour of #LuigiGalvani, the professor who gave #Volta the idea for the first battery.
Pyotr Leonidovich Kapitsa shared (with #ArnoPenzias and #RobertWoodrowWilson) the 1978 #NobelPrize for Physics for his basic strong magnetic field inventions and discoveries in the area of #low_temperature physics. He discovered that helium II (the stable form of liquid helium below 2.174 K, or -270.976°C) has almost no viscosity.
