Today is Pi Day, the day that starts off 3.14 and celebrates the ratio of the circumference of a circle to its diameter. This day gives mathematicians from around the world an opportunity to educate everyone and celebrate the beauty of the universe. So it seems appropriate to me that Albert Einstein, who once said Pure mathematics is, in its way, the poetry of logical ideas was born on this day in 1879. Happy Pi Day, Albert Einstein, and thanks for all your wonderful insights and explanations about how reality works!

Happy Square Root Day! It happens only 9 times a century, when the day and month are the square root of the last two digits of the year; and this year it happens only a few weeks before Pi Day, first celebrated at the Exploratorium back in 1988. Then there is Pi Approximation Day on 22/7 of course, also known as Casual Pi Day. For fun from a different direction Reaper returns to the airwaves with the season 2 premier tonight. I didn’t expect to like the show so much when it first aired, but Ray Wise was the absolute best choice to play the Devil, and all by himself brings the show up several levels. Hope they can keep both the comedy and suspense up for another full season!
