True enough. Then when you feel really brave, start a course in electronics and teach yourself how to work with schematic diagrams and all the symbols they use there. <grin> I have done that as well and had lots of fun. The schematic prints were the most fun, making sure that you stayed tracking on the same line of the circuit. Also, some of the symbols they use are pretty complet and considerable harder to recognize at first. Best, J. R. -------------------- J. R.

R., Thanks for that information, and your great comments. I just finished a book of essays about math concepts and I was particularly fascinated with number theory and calculus, but I suppose it will be a while before I get to those since I'm starting with first year algebra. I peeked into the chemistry and it focuses on problem solving rather than the physical aspects; there are some books out on web braille that even have the periodic table in braille, although I hope it will be in the print workbook too. I look forward to the challenge of learning to think outside of boolean algebra and the programming world. I may not get far, but it looks like fun. I'm an old English major so I may not realize what I'm getting into, but it's never too late to find out.
