I retired in 2006 and bought Mathematica and a stack of math books with the goal to teach myself to become a world-class mathematician. I am on pace to achieve that goal sometime shortly after the next Ice Age.

I consider myself a Mathematical Mutt (no papers) who occasionally ventures off the back porch to play in the yard with the big dogs.

I donate regularly to the The OEIS Foundation.

When I look at the patterns, I can hear the wheels turning. When I look at the math, I find out the hamsters have died.

comment Creating a "math.SE needs your help" thread
I suggest a moderator-inserted meta-tag, Herculean, to indicate that a smart/tough solution is needed. This meta-tag would be available on MO and math.SE for anyone to select just as she would select her favorites. Perhaps, a script similar to interesting could become available to allow book-marking these searches.
