Unsolved Problems As of December 2002, 39 Mersenne Primes are known. There are thus 39 known evenperfect numbers. The following questions have not been answered to date http://www.math.utah.edu/~alfeld/math/conjectures.html
Extractions: Understanding Mathematics by Peter Alfeld, Department of Mathematics, University of Utah One of the things that turned me on to math were some simple sounding but unsolved problems that were easy for a high school student to understand. This page lists some of them. To understand them you need to understand the concept of a prime number A prime number is a natural number greater than 1 that can be divided evenly only by 1 and itself. Thus the first few prime numbers are You can see a longer list of prime numbers if you like. Named after the number theorist Christian Goldbach (1690-1764). The problem: is it possible to write every even number greater than 2 as the sum of two primes? The conjecture says "yes", but nobody knows. You can explore the Goldbach conjecture interactively with the Prime Machine applet.
