Why is there a random watermark on an xkcd? The original is here, for anyone who wants the alt text: https://xkcd.com/2943/
That's actually an interesting one.
The 'p' could have a different meaning for a variety of languages. 'Puissance' in French, 'Potenz' in German, 'potential' or 'power' in English, 'pondus' or 'potentia' in Latin, or 'Potens' in Danish (probably the Danish one originally, since it was a Danish chemist who first introduced the measurement).
It's very fun that because of the vagueness, various languages can have its meaning directly translated to their own.
All those words have the same meaning.
And the same origin, it's not a coincidence they all start with P
There's also pico-, prefix for 10^-12
Protons. As in protons, How many. On a weird logarithmic scale with 7 in the middle, of course.
The p is for potential, as in potential Hydrogen. pH can be used to establish a concentration of protium (H+) in solution. When learning about pH in school, we used pOH (potential hydroxide) as well to speak about bases.
Oh we're going to pHight today, is that it?
Easy. Pico Henry. Not sure why chemists are so concerned with such a small amount of magnetism though...
It's power of Hydrogen. We should've been using Watts to measure it this whole time.
I was taught potenz in my school textbooks. potenz Hydrogen
Phat-ass hydrogen
Negative log of the concentration of…(Hydrogen ions, in pH).
Potencial de hidrógeno
