English physicist who established the mechanical theory of heat and discovered the first law of thermodynamics (1818-1889)

Usage examples of joule.

GeV, requires an energy input of about 7,000 joules and a persistent circulating current of 250 amps, if a 20 km deployed superconducting wire coil is used.

When the discharge setting is activated, a stream of particles are released through that lens, a power of about two thousand joules to a three-second burst.

And when one collapses, all those Joules come out at once, one way or another.

They had discovered the X ray, the cathode ray, the electron, and radioactivity, invented the ohm, the watt, the Kelvin, the joule, the amp, and the little erg.
