CLEVELAND, Ohio – April 4, 2016 wins a triple crown in the department of cosmic coincidences. The day marks Major League Baseball's Opening Day, the NCAA basketball championship and Square Root Day. All provide potential fodder for math geeks who scrupulously compile baseball stats, slaved over Sweet 16 and Final 4 basketball playoff match-ups, and appreciate a date when both the month and date are the square root of the year's last two digits (4,4,16).
