  •  One of my degrees is in math (6+ / 0-)

    I know precisely whereof you speak about the rush that occurs when you "see" how equations can be used to describe an underlying physical truth.

    I still contend that the ability to speedily do grade school arithmetic in your head is helpful in getting to the epiphany.

    •  Indeed. No argument there. (4+ / 0-)

      I suppose, I would like to see kids also learning more about more complicated concepts that better represent Mathematics and its relationship to the natural world.  All to often ailure to appreciate Mathematics derives from failure to understand its potential.  This can be remedied.

      Also, some of the best mathematicians I know are piss poor at arithmetic!

    •  one of my inspirations about math and 'rithmetic (4+ / 0-)

      was a local grocer (the 1950s) who did almost all sales in his head. And in those days all the locals would run tabs 'till the end of the month. We'd just put stuff on the counter and he'd say "that'll be $1.32". He'd write the prices on a slip of paper and give it to us to keep, and a copy in his book, but he was never wrong.

      As a consequence I've always sort of kept a reasonableness tally in my head when shopping, and more than a few times the Scanner/Register will say "23.45" and I'll go "Wait, that can't be right...I don't know what the exact answer is, but that isn't it..."

      Without geometry, life is pointless. And blues harmonica players suck.

      •  A real feeling of power, knowing when there is (1+ / 0-)

        a gross messup and saving $10 and up.

        What is fun is walking up and putting money on the counter, including tax.  The total comes up and the stack gets pushed.   looks on faces are worth the bit of mental stretching
