The category provides adequate description for this question
Apparently I'm not allowed to go off on more than one topic during one question, so I'll just mention a few random subjects and you can choose what to help me with.
Ok first, I received this postcard yesterday and I just dont understand it. There's a scan of it at [Link](Mouse over link to see full location) (339KB). So far I've found out that if the first letter of a word is a capital, that's a dash in morse code, and if it's not, that's a dot, with the punctuation used to separate letters. However, I'm told there's another message, can you help me?
Second, I know this person called MFS. MFS is often very spontaneous on internet forums, but he keeps a very normal, helpful and coherent advice column. Can you tell me of anything that might motivate him to do this?
And if you don't like either of the above questions, then have one more fitting your area of expertise. I have to do a chemistry investigation this year, counting for a third of my final mark. I'm in a class of 17-18 year olds (not one myself, but ignore that) and I'm really a mathematician so I like the logical and numerical side of chemistry. I get about 20 hours of practical time around January. I'm thinking of doing my investigation on electrochemical cells, possibly including whether they can be used to determine a solution's concentration. Given that information, would you think it a good topic? I can choose pretty much anything if you have a better suggestion.
If you've read this far I'm very impressed so thanks even if you don't choose to comment on any of the subjects

well, I can't say that the Morse Code message makes a lot of sense, as I got "Jon, you may now feel uber smug. B" As for another message, well, I could easily over-interpret the choice of language used.. perhaps I'll stare at it some more later...
I know this person called MFS, too, since generally that is me. Spontaneous, you say? Sometimes, but oft it is a planned statement, wrought with meaning beneath the lunacy. I am here posting advice because, well, because it is part of my non-ending job of stalking spacefem.
Electrochemistry can and is used to determine concentrations of various substances. I was using a fluoride-specific electrode to detect fluoride levels in a solution. The electrode responds to F-, which it gives a mV signal, which can be correllated to a known concentration of a standard. Great fun. I have also used annodic stripping voltammetry to determine parts-per-trillion levels of heavy metals (except mercury) in a mercury amalgam. So yeah - your topic will not only work, but you should be able to find lots of info on it.
