my dad made us (myself & sibs) memorize the first 10 digits of pi when we were in 3rd grade. I don't think myself or any of my sibs will forget.....3.1415926536 The long term effect of this damage is that I never know when to stop and round off the goddam real-world solution in hardware designs. I spend wayyy too much time on tolerance computation. Through dedicated 12-step coaching was I able to stop constantly computing things like the total (including tax) of every item in the grocery cart. I see the similar tendancy in my son who earned a blue ribbon on his 7th grade science fair project. His topis was: 'Matematical patterns found in musical computations by Bach'. No, I think he only can recite the first 4 digits to the right of the decimal of pi by memory.
