I don't get it. Wayne is obviously NOT making a big deal of the "long division style square root algorithm" (henceforth, "LDAsq"). It's nice, he likes it, it is clearly secondary for him, he is not promoting it at all and, in the plain meaning of English words, he most certainly does not assert anywhere in his comment that the LDAsq is "THE way". Note the last paragraph,
>Interpolation is a different matter entirely. We have >lost a lot by avoiding the subject...
In other words, if Wayne is making one essential assertion, it is that interpolation is important in a way the LDAsq never was. If the man does not want to be dragged into a lengthy exposition on a point he mentions only in passing, and that he is clearly not terribly interested in, I find it hard to fault him.
I do note one confusing element in Wayne's comment. First he writes he did not teach the LDAsq when he taught high school, but then writes he explains the algebra of it in his classes. I take that to mean he explains the algorithm in the college classes he has been teaching in the 40 years since he taught high school. A clarification from Wayne would be nice.
I find myself inexorably drawn to my original point. If you want to discuss square roots and how to extract them by hand, why waste bandwidth criticize Wayne? Why not just take it up with somebody who wants to explore the subject?
If nobody in this forum wants to do that, perhaps there is another, more suitable, forum. Suggestions, anyone?
