I dont think people are "opposed" to "speaking" math - For myself, I would love to be fluent in it, and I fully recognise that it is THE universal language by which to describe and evaluate most physical phenomena. I do not know the reason, or who to 'blame' - was it those who provided my education, or is it that I suffer from some 'impairment' (mathematical dyslexia?) - all I can say is that I have spent more time attempting to master this language than I have spent on anything else - I have gone right back to the basics, and worked through arethmetic, algebra, trig etc.. and while doing this I understand and painstakingly get the sums right .. This is also true when I get to elementary calculus - I can understand it and work with it... But a week after I have put the books down, the basic understanding remains but I get lost when doing calculations.. and 6 months later I am at pre-calculus level.

Things are improving a bit - but I have been disabled by this problem for years.. I have worked in science and technology for 30+ years.. And I know what the cost of this 'disability' has been.. I have also met many engineers and a fair number of scientists who suffer from this 'disability' - I am candid about it, and disclose this weakness to potential employers and collegues - People in science / technology tend to keep this weakness 'under wraps' and somehow manage to bluff their way through - not a game I am willing to play.

There were no electronic calculators in my day - and I find them impossible to use for complex maths anyway - unless one understands what one is trying to do, I dont think a calculator can help.. Pencil and paper are not the problem, so its probably the brain! LOL! ;-)

I have managed in electronics and physics through a sort of 'visualization' process - resorting to maths so as to tidy up component values etc.. design the circuit with a rough idea only as to optimum values, visualize the operation of the circuit to locate any potential problems, calculate optimum component values (usually using Excel), run a simulation, build it.. But for most of my best circuits I cannot say how I do it - go to sleep thinking about the problem, wake up with some bizzarre circuit in my head, draw this circuit and see how it works, then go through the optimization process described above.. The only problem I have with this is that it almost feels like cheating to say I designed the circuit!

If there is enough interest, we could start this in the new year - or perhaps just start it anyway.. interest can be determined as we proceed. I do not have much spare time at present, so would hope others will contribute to the 'teaching', and think the pace will probably be quite slow.
