Michael Hardy

I have a Ph.D. with a minor in mathematics and a major in statistics.

At meta (dot) math (dot) stackexchange (dot) com you may seek information or even make suggestions provided you stay away from any topic that might cause it to be suspected that you will suggest changes in customary ways of doing things. That is rigidly forbidden by an unstated customary rule with which I disagree. The rule is enforced by bullies.
