I get to give joules to my patients as they’re ready to come off bypass in the operating room! Yay!
Measuring
Big deal. Joule was nothing more than a newton meter.
(Hopefully, some folks will get that.)

It’s amazing that engineering school never has the time to teach you about the great men who did all the foundational work for modern society.
Thanks for posting this..
Mr. Joule got slighted. I was taught that all constants and units of measurement named for men are to be capitalized. For example, think of Watt, Farad, Volt, Fahrenheit, Coulomb, Pascal, Ampere, Centigrade, and Erg.
Wikipedia says “The SI derived unit of energy, the joule, is named after him.” Shouldn’t it be the “Joule”?
What really irks me is these are all dead white guys! Why do they get all the credit? This is unjust!
As an adult, Joule managed his father's brewery. Science was merely a serious hobby. Sometime around 1840, he started to investigate the feasibility of replacing the brewery's steam engines with the newly invented electric motor. His first scientific papers on the subject were contributed to William Sturgeon's Annals of Electricity. Joule was a member of the London Electrical Society, established by Sturgeon and others. Motivated in part by a businessman's desire to quantify the economics of the choice, and in part by his scientific inquisitiveness, he set out to determine which prime mover was more efficient. He discovered Joule's first law in 1841, that the heat which is evolved by the proper action of any voltaic current is proportional to the square of the intensity of that current, multiplied by the resistance to conduction which it experiences.[3] He went on to realize that burning a pound of coal in a steam engine was more economical than a costly pound of zinc consumed in an electric battery. Joule captured the output of the alternative methods in terms of a common standard, the ability to raise a mass weighing one pound to a height of one foot, the foot-pound.
By the way, what kind of tie knot is that? Is there such a thing as a quadruple Windsor?

Watt is better then Joule any day!
