So I’m working away at this thing and reading tweets and this article about OpenStax and how it is now doind COURSEWARE not just textbooks. Of course, so is … bccampus 🙂

Little old me can’t do anything compared to that… but will there be a way for my little old stuff to be useful maybe? B/c they’re not doing the basic math stuff.

But I also feel the need to make my multisensory explanation about WHY 1/R1 + 1/R2 = 1/RT. (why if it takes 6 hours for 1 guy, 8 hours for the next guy, to work together you add the reciprocals and get the reciprocal for how many hours it’s together.) I just splained to one of my “gotta see why” peeps and … it wants something to be able to go back and see, b/c not everybody is a verbal gerbil like me 😛

But first the times tables…
