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 Is there a notebook to create entries for OEIS?
@belisarius, it's probably a variation of the one in my edit above. If someone answers, I can check it off; or I could delete the OP. What do you think?

comment Is there a notebook to create entries for OEIS?
@Mr.Wizard, I think it set up all the sections on OEIS in their proper formats. I'm not sure if it provided a method to post on OEIS.

comment Why does a magnetic field go anticlockwise of the direction of current?
Clock dials were designed to mimic the chirality of sundials in Northern Hemisphere. If the clock had been invented south of the Equator, it would be the other direction.

+1 for confirming my suspicion about the clarity. I will play with it a bit to determine if it fits into my other functions.

@anorton, He is the only one who had posts under the appropriate tags. So, I trust that his vote wasn't just being picky.
