Why is there a random watermark on an xkcd? The original is here, for anyone who wants the alt text: https://xkcd.com/2943/

I scrape the bottom of the internet barrel through a special firefox container. It's like growing memes on agar. Sometimes there's a little contam.

Fair, but also, you could look up XKCD comics by their name or transcript and link to them directly when you come across them.

My goal is to spend less time online, if I did this for everything I would not be able to keep up with this. I do it for fun.

Søren Sørensen, who came up with the concept of pH, wasn't clear on what the letter "p" meant. It does involve powers of 10 and can be measured using electrical potentials, so the best guesses are "potential" or "power", or several words that mean "power" in other languages and also happen to start with "p". Bottom line, we don't know, and unless somebody discovers more of Sørensen's notes or a way to speak with the dead, we never will.

[–] Geodad@lemmy.world 20 points 1 month ago (1 children)

We can all speak to the dead. The problem is that they can't answer.

[–] LovableSidekick@lemmy.world 11 points 1 month ago* (last edited 1 month ago)

That's why I was careful to say, "speak with dead," (after the D&D spell) implying a conversation.

[–] JayDee@lemmy.sdf.org 23 points 1 month ago (2 children)

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.

[–] mmddmm@lemm.ee 8 points 1 month ago

All those words have the same meaning.

[–] Gutek8134@lemmy.world 2 points 1 month ago

There's also pico-, prefix for 10^-12

[–] Deconceptualist@lemm.ee 20 points 1 month ago (1 children)

Protons. As in protons, How many. On a weird logarithmic scale with 7 in the middle, of course.

[–] ArsonButCute@lemmy.dbzer0.com 6 points 1 month ago

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.

[–] TropicalDingdong@lemmy.world 20 points 1 month ago

Oh we're going to pHight today, is that it?

[–] pryre@lemmy.world 15 points 1 month ago

Easy. Pico Henry. Not sure why chemists are so concerned with such a small amount of magnetism though...

[–] loomy@lemy.lol 9 points 1 month ago (1 children)
[–] Someonelol@lemmy.dbzer0.com 7 points 1 month ago

It's power of Hydrogen. We should've been using Watts to measure it this whole time.

Phat-ass hydrogen

[–] IsoSpandy@lemm.ee 4 points 1 month ago

I was taught potenz in my school textbooks. potenz Hydrogen

[–] Puttaneska@lemmy.world 3 points 1 month ago

Negative log of the concentration of…(Hydrogen ions, in pH).

I don't get what the joke is

[–] fossilesque@mander.xyz 4 points 1 month ago* (last edited 1 month ago) (1 children)

Nobody actually knows what the p means but we keep using it anyway. The guy who coined it is long dead.

[–] BuboScandiacus@mander.xyz 2 points 1 month ago (3 children)

Doesn't it mean "potential" ?

[–] AwesomeLowlander@sh.itjust.works 3 points 1 month ago (1 children)
[–] BuboScandiacus@mander.xyz 1 points 1 month ago (1 children)

Yes, and also, whoosh

[–] Midnitte@beehaw.org 2 points 1 month ago

Potentially

[–] AnarchistArtificer@lemmy.world 2 points 1 month ago

I thought it was "power". That's probably wrong though.
