Anyway peeps of a certain age! Do you remember these log tables? I was fifteen before I owned my first calculator. With a myriad of technology, literally at his fingertips, Louis can't comprehend the effort involved in seemingly simple mathermatical tasks. Finding the square root of, say, 77.5 involved trawling through a book of tiny numbers and maybe a few extra back of the envelope calculations before the answer finally 'popped' out. I think that we'd all agree that things have changed for the better here. We're freed up to focus on problems with more meaning rather than the minutiae. Perhaps our responsibility now is to make sure that we ourselves and our kids are doing this and not frittering away all that extra time!
