In Support of Inaugurating February 7 as ‘World e Day’

Mathematics is a fascinating subject to some people, but a horror to most. Formulas and rules abound to govern purely abstract relationships that appear alien to ordinary life. Yet, mathematical laws govern our entire world, and the Universe. Physicist Max Tegmark believes that the Universe is itself entirely mathematics, i.e., we are all elaborate formulas in some metaverse. Embedded within the mathematical laws are inscrutable constants, such as pi and e, where e is the so-called base of the natural logarithm. e is roughly 2.718281828…. Although Pi (3.14159…) has an official day, 3-14, or March 14, e has yet to acquire this honor. Last year, I wrote in honor of World Pi Day. This year, I propose making 2-7, or February 7, National or World e Day.

World Pi Day: 3/14 — The Ongoing Mystery of Pi

Today is National and World Pi Day because the numbers of the day (3-14) match the first three digits for pi or , the Greek letter, 3.1415926535897…  Although most people think that  is relegated to just geometry and trigonometry, the number pervades all of mathematics and the natural sciences, even statistics.

3-14-15 brings a once in a lifetime Pi Day

The pursuit of pi, the numerical constant which represents the ratio of a circle’s diameter to its circumference, is a subject which has driven mathematicians to extremes. The date 3/14/15 coincides with pi calculated to five digits (3.1415). The next time this will occur will be 100 years from now, making this year’s Pi Day a once in a century event.
