Greetings!
 
My name is David E. Sanders.
 
My interest in primes dates back to grade school (many, many years ago).
I am interested in them for their own sake, and not for any applications.
My formal mathematics training extends to the first year of college calculus,
plus some statistics, but I have no formal training in number theory.
 
Mersenne primes are especially interesting to me.  Just through simple
observation I found the relationship
 
                  If p is a prime, then p evenly divides 2^(p-1)-1
 
But I cannot formally prove this.
 
On the other hand, I can prove the assertion that
 
                  For any n=composite number, 2^n-1 is not prime.
 
Much of my study has been based on these two ideas.
 
But I think it is now time to learn the more technical, detailed, and formal
stuff in prime number theory, especially for Mersenne primes.  I am
currently reviewing the material at http://primes.utm.edu/glossary/.
