First there was Pi Day (3/14). Then, this year only, was Square Root Day (4/4/16). Now today (6/28) you can celebrate “the most perfect day of the year,” according to Scientific American. The numbers 6 and 28 are both perfect numbersâ€”they are the sum of their divisors (1+2+3=6; 1+2+4+7+14=28). If perfect numbers aren’t your thing, today is also Tau Day! In geometry tau is often denoted to represent pi multiplied by 2 (3.14 x 2 = 6.28). Source – Physics today
