History of Infinity Day

Free AdviceInfinity Day was first conceived and created by Jean-Pierre Ady Fenyo, a philosopher, poet, journalist, and science-fiction author. As a sidewalk philosopher, he became known back in 1987 as “The Original New York City Free Advice Man” (see The New Yorker magazine’s August 17, 1987 issue.) He has since become known as a celebrity there.

Infinity Day was begun in 1987 and has been celebrated in the form of peaceful, non-violent, and lawful demonstrations for philosophical inquiry, freedom of expression, freedom of speech, and ethics in society, throughout the world. Thereafter the founder took it to various cities in the US and Europe. He now lives in London.

    With this and yellow pig day (17 July ) I am all set.

    10:04PM was the time on the Back to the Future clock tower when it was struck by lighting. Those two zeros can be viewed as an infinity….which is appropriate for time traveling. That leaves the 1 and 4 to make a 14. We find 14s all over the place in physical sciences. There are 1440 minutes in a day, the first two numbers in Pi after the decimal are 14, the generations of the ancestry of Jesus Christ from Abraham to David to the 2nd Temple to his birth are measured in 3 sets of 14 (see Gospel of Matthew), the moon has a 14 month orbit and a 14 degree variance, Carbon-14 Dating measures Nitrogen 14 and Carbon 14. The list goes on and on.

    Bill, your list of interesting 8’s made me think of – Why was 6 afraid of 7? Because 789.

    And my favorite date with respect to numbers is Pi Day – especially two years ago and even better in morning. 9:26:53 to be exact.

      789: I think there should be a history behind that.
