Using pictures instead of symbols in an equation.
I'm going to give a talk at a local radio club on Monday and want to produce some handouts. The audience will be pretty non-technical, so writing lots of equations with Greek symbols is not going to be on! So I could resort to something like S/N = s / (n1 + n2 + n3 +n4) where s = signal power n1 = thermal noise n2 = made made electrical noise n3 = electrical noise from the Sun. etc That would be better than Greek symbols, but I am still not sure it will be understood too well. So I was thinking of pictorially represent what they are. s = signal power (perhaps draw a radio transmitter) n1 = thermal noise (perhaps draw a coal fire) n2 = made made electrical interference (perhaps draw a computer) n3 = electrical noise from sun (perhaps draw the sun) Is there a way of doing that in a notebook, such that that images (gif, jpeg etc) could be used in equations and computations preformed on those images? OK, you think I am mad! Perhaps I am, but I'm trying to get the idea of using equations across to an audience where although a few might be chartered engineers, the vast majority are frightened by Ohms law. They *should* all have a clue what equations are, as they have all passed the rather basic exam for an amateur radio license. But for anyone that know s much about that (in the UK anyway), you would have to be pretty thick to fail it. If anyone has attempted this sort of thing, I'd be interested. I think more often than not trying to teach something to someone whose technical abilities are far below your own is more difficult than teaching PhD students things. -- Dave K MCSE.
