Walker, the below is a true proof, because in step 4) W+1 is recognized as being necessarily prime since it is divisible by itself and by 1 and that none of the finite list of primes divides into W+1, so by definition W+1 is necessarily a new prime not on the finite list. 1) Definition of prime 2) Hypothetical assumption, suppose set of primes 2,3,5,7,.. is finite with P_k the last and final prime 3) Multiply the lot and add 1 (Euclid's number) which I call W+1 4) W+1 is necessarily prime 5) contradiction to P_k as the last and largest prime 6) set of primes is infinite. Mr. L.

All that Davidson achieved in seven steps (he miscounted the steps) is that W+1 is a prime number. He has not contradicted 2) because Davidson fails to realize that W+1/W+1 and is divisible by 1 so that W +1 is a prime number. So he has no proof and he has no contradiction. So Mr. L. Walker, you are responsible for having encouraged Davidson into believing his misguided steps and his convoluted use of half of a theorem. And L. Walker needs to state that Davidson is wrong.

I see you have still not answered my question. Is "Every natural >1 has at least one prime divisor" a true statement or a false statement. Your bizarre idea that the statement is "incomplete" shows how primitive and confused your thinking on these matters is. By Archie Poo "logic" every theorem would be incomplete as you could always AND it with some another theorem or theorems. |
