Also: "adsorbs."

EDIT: upon further research, I find that "adsorption" is actually also a thing, but it appears that here they meant the traditional absorption. Adsorbtion definitely isn't a thing. Also it sounds like a baby trying to say "abortion," which is weird.

What possesses people to give things such similar names? And while we're at it, mathematicians: stop using variables that rhyme. Bs, Cs, Ds, Es, Ps, Zs, it makes my head hurt. Would it kill you to chuck an H or a Q in there? M and N, now thats just purely vindictive. How am I supposed to cope with that?

After writing this comment I think the spelling part of my brain is now fried forever. And to think I've been walking around merrily saying "absorbsion" all these years...



I learnt the verb "adsorb" in high school chemistry. Why is adsorption not a thing? (Although it does look like the article meant "absorption" and not "adsorption".)

Quote for those not in the know:

-----

<<<"Absorb" refers to a situation where something is taken into a medium, and disappears as a consequence (from?). "Adsorb" refers to a situation where something gets stuck onto (to?) the surface of a medium.

We would use "absorb" for when light is absorbed by a coloured or opaque object, or for when water is soaked into a sponge, or even for when my students manage to "take in" some of what I am telling them. It is an ordinary English word.

"Adsorb" is used for a very specific situation where molecules get stuck onto a surface. It does not occur as a word in ordinary language, outside its scientific meaning. Adsorption is very important, because many chemical reactions can go a lot faster when the reacting molecules are adsorbed at a surface (reactions of hydrogen gas on the surface of nickel, for example), or chemical reactions can be prevented by the presence of a barricading adsorbed layer on the surface (aluminium failing to react with air, for example), or impurities can be removed from a solution by adsorbing them onto a finely divided solid (activated charcoal for decolorizing solutions, or for medicinal use, for example).>>>


"adsorb" versus "adsorp."

Now you can see why my brain was fried trying to type all that correctly. Not only do the phonemes sound the same, the letters are mirror images of each other. I think I now know how dyslexics must feel all the time.


> but it appears that here they meant the traditional absorption

Sorry to add extra "fry" you your brain, but it appears they really did mean "adsorbtion" -> http://en.wikipedia.org/wiki/Zeolite

Which makes a lot of the science understandable. I can't help thinking that by saying "OMG hard science, so here is a massively dumbed down version" they actually made crucial parts of the theory incomprehensible :)

Case in point being; adsorbtion explains later comments about why surface area is important.


>And while we're at it, mathematicians: stop using variables that rhyme. Bs, Cs, Ds, Es, Ps, Zs, it makes my head hurt.

I had a linear algebra teacher who was (I think) from Ukraine. Roughly all letters rhymed when he said them, and "a", "e", "i" were homophones.


What possesses people to give things such similar names?

Ad = To. Ab = From. That's Latin. People that invented it are long dead, so we have nobody to insult when we can't tell abductor from adductor.
