Variables

Today's Physics class was a dizzying flurry of variables. We seem to have reached the point where the lecture is pretty much "alright, so if X/T = V and E=delta-V/delta-X, and you know that V=Ad, then how many different variables did you just represent with the single letter V?" The answer is 3, velocity, voltage, and volume. Yes, we have long since run out of letters in both our alphabet and the Greek alphabet. We have even used up all the capital letters of all letters in both alphabets. We have reached out limit. If that is the case, why does science still insist on naming so many variables!? Sometimes I get the feeling that scientists make up variables just so they can name the unit that goes with the variable after themselves!

Well guess what people, the root means squared of the number of electrons in a single area A over change in magnetic flux per unit second is now called the Collective Uselessness of the Data and is described in units of McPherson. Ha ha!

  1. Is it called McPherson because you discovered it, or because the McPhersons are collectively useless?

  2. Hmm...a dizzying flurry of varibles--that sounds like what Cal 3 is every day. Only the letters aren't always representing variables, they're often used to symbolized mathematical operations too. Basically, the class notes are pages and pages of letters and symbols.

    I like your variable names. :) Do you actually get to use whole words for your variables instead of just single letters?

  3. Duncan, the physicists should start naming the new constants "constant dog" like Ariel's Linear Algebra teacher.

  4. Actually, Luke, that was theorim dog. Constants (in math) are always just a single letter. Still, it might be interesting to name all of the constants in Physics after farm animals, but only if you're Old MacDonald.

  5. You could label them McP.

    In Ariel's math, the alphabet soup sometimes spells out words, which is very funny to me.
