If you want to claim that something can exist, then one example is sufficient to show that. So one long-winded and pithy quote is enough to show that long-winded and pithy quotes can occur. If you want to show that something can't exist, though, you've got a tough problem as it's possible that the thing exists somewhere you haven't looked. Some things can however be shown not to exist by mathematical proofs. <BR/><BR/>For example, I can show that the prime numbers are infinite with a proof by contradiction. <BR/>Theory: Prime numbers are infinite.<BR/>Proof: Assume the opposite, there is a largest prime number, N.<BR/>Now multiply all the prime numbers from 1 to N together and add 1, so 1*2*3*5*7*11*...*N + 1. <BR/>You now have a number that is divisible by none of the existing prime numbers. So therefore either this number is either prime itself or is divisable by some other prime that is larger than N. Therefore there must be another prime number larger than N. Therefore our starting assumption is wrong. Therefore there cannot be a largest prime number.

An instructor should strive for setting up a "perfect practice" but the practice can be far from perfect and still have a positive effect. If the student were "Perfect" the student wouldn't need the practice.<BR/><BR/>To increase expertise requires "determined practice" on the part of the individual.<BR/><BR/>The coach wanted the players to share his aspiration of perfection. It worked for you, but it doesn't really have "wide applicability" as stated.<BR/><BR/>Back to the practice field.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-25541994.post-47539290780173027462009-02-03T13:11:00.000-05:002009-02-03T13:11:00.000-05:00An old baseball coach of mine used to say, "Practi...An old baseball coach of mine used to say, "Practice doesn't make perfect.
