The Walden Effect: Farming, simple living, permaculture, and invention.

A happy square root day

square root of JapanIf you can multiply the day by the month and it equals the last two digits of the year, then you are in the middle of Square Root Day.

This fantastic gift from the multiverse of numbers is a puzzle that's only offered nine times a century, and so far has only been realized by .09 percent of the population.

Is it a coincidence that it falls on the ninth year of this century...with .09 percent believing...and only nine times every 100 years? Will you be the next to solve this mathematical brain teaser and join the ranks of this shrinking population, or are you like me and have yet to discover the full problem much less even part of the solution?

Make your plans now for the next Square Root Day which will be April 4th 2016.
