Happy Geometric Mean Day!  The geometric mean of two numbers and b is


which makes today a Geometric Mean Day!


A consequence of this is that the numbers in today’s date form a geometric progression

I was recently asked “Was ESET a bad program or a good program last year?”

“Yes,” I replied.

The crowd laughed, but I was a bit saddened when I realized they didn’t understand the joke the way a mathematician does, and merely thought I was being inane. One lass even asked “are you a poli-sci major?” in a true bout of irony.
