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 22 points 10 months ago (1 children)

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

[–] LovableSidekick@lemmy.world 13 points 10 months ago* (last edited 10 months 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 10 months 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 10 months ago

All those words have the same meaning.

[–] Gutek8134@lemmy.world 2 points 10 months ago

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

[–] TropicalDingdong@lemmy.world 20 points 10 months ago

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

[–] Deconceptualist@lemm.ee 20 points 10 months 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 10 months 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.

[–] pryre@lemmy.world 15 points 10 months ago

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

[–] Someonelol@lemmy.dbzer0.com 7 points 10 months 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 10 months ago

I was taught potenz in my school textbooks. potenz Hydrogen

[–] Puttaneska@lemmy.world 3 points 10 months ago

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

I don't get what the joke is

[–] fossilesque@mander.xyz 4 points 10 months ago* (last edited 10 months 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 10 months ago (3 children)

Doesn't it mean "potential" ?

[–] AwesomeLowlander@sh.itjust.works 2 points 10 months ago

Yes, and also, whoosh

[–] AnarchistArtificer@lemmy.world 2 points 10 months ago

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

[–] Midnitte@beehaw.org 2 points 10 months ago

Potentially
