Default Those pesky Abbreviations!

Hello good afternoon my friends!

Just stumbled once more over Mr. Ohm.

I find it hard to remember that, for example, the ampere (A) is referred to as I.
Hell, why is that? Just so or is there a sort of a etymology to the denotations?

I is French for intensity of current. It was used by Mr. Ampere himself.

The incredible André-Marie Ampère indeed used "intensité" or I. He died in 1836 and he developed a theory that magnetism is caused by small currents that occur within the magnetic material. This was proven 60 years after his death.

The U for voltage is another story As all stuff was started in Europa things became named often in the language of the founder which could be any European country. The unit name often being derived from the name of the founder. The inventors of that time were contrary to those who achieve things in modern society exclusively male.

So I may introduce an new unit for an old energetic phenomenon (in new socks): unit „D“ (like david) for varying levels of ignorance.
Mille millions de mille sabords!
(Ok, this was in 18th/19th century, but weren’t there any women in the club (or were they just ignored)? Later on we had marie curie among others…)

D = 1/(IQ x W). Ignorance =
1/(intelligence x effort)

I just mentioned it as it were almost all white males. The same sort that is seen as the cause for all bad things today in the woke culture. So anyone using their inventions maybe practices “appropriation” if I follow the intense ignorance and stupidity of the woke culture.

!n argument can be made that Centigrade is far more useful than Celsius.

But you are correct, units get named after discoverers; Bells, Faraday, Tesla, Coulumb, mho, Gauss, Kelvin, Newton, Hertz, Volta, Amp....

Where mho is Ohm in reverse to indicate what the rest of the world calls Siemens. "mho" is according the SI an "unaccepted special name for an SI unit".

BTW Georg Ohm was ignored by the physicists in his home country even after his theory was accepted in the US. It took another 20 years to get acceptance.

It's on my likeable list since the unit of measure tells you something about the physical property, as long as you understand Ohms
