#### What is Pi (π) Day About Really?

There are a lot of pie days1 and, as I first started an internet presence writing about *pie with an e*2, I could go on at length about its history, regional and cultural favorites and traditions, recipes, savory, sweet, techniques, ingredients, pie-worthy fruit, books, pie makers… . It’s a subject about which I’m passionate and I don’t believe any one person could know in just one lifetime everything there is to know about. This may be one of the reasons that I continue to find it fascinating. But, that pie…*the one with the e*…is not what today is about.

Today is Pi (*π*) Day. It’s the day for us to celebrate math and science, and those who are endlessly fascinated by *these* subjects, and how introducing children to them and making them a part of their lives at an early age, is so important.

*Math and science are cool.*

Although I am not a mathematician or a scientist, every day I am the beneficiary of the important work of those who are, like Elizabeth Blackwell (1821-1910) who championed the participation of women in the medical profession and opened her own medical college for women, Louis Pasteur (1822-1895) whose research in chemistry led to breakthroughs in the understanding of the causes and preventions of diseases, which laid down the foundations of hygiene, public health and much of modern medicine, Marie Curie (1867-1934), who pioneered the study of radioactivity, Charles Drew (1904-1950) whose work on blood storage and blood banks has helped to save the lives of millions, Rachel Carson (1907-1964) who is credited with advancing the global environmental movement, Alan Turing (1912-1954) father of modern computer science, Katherine Johnson (1918-2020) whose calculations of orbital mechanics as a NASA employee were critical to the success of the first and subsequent U.S. crewed spaceflights.

So sure, make a pie today, but remember what this day is really about.

**Facts about March 14**

The birthday of Albert Einstein, one of the greatest physicists of all time.

The death day of Stephen Hawkings, the great theoretical physicist and cosmologist.

The value of pi was first calculated by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.

The Greek letter

*π*was introduced as the symbol for Pi by William Oughtred in his works dating back to 1647, later embraced by the scientific community when Leonhard Euler used the symbol in 1737.*π*is a part of Egyptian mythology and the pyramids of Giza may have been built on its principles.*π*, along with the radius, is used to calculate the circumference of a circle, the area of a circle or the volume of a sphere.*π*is used in weather calculations. Since cloud droplets are near spherical, pi is used to calculate how much water is in a cloud knowing the number and size of the drops.Physicist Larry Shaw started celebrating 14 March as

*π*day at San Francisco’s Exploratorium science museum.Below is a link to the 2022

*π*Day Celebration at the San Francisco’s Exploratorium where John Sims performs work from his music project*31415: The Pi Collection*and showcase his Pi Quilt. Educators also share pi’s mathematical history and activities at the museum and ones you can try at home.

Well there was a short-lived blog I named “Foodie Consort” back in 2006 but the foodie I was consort to back then made it very clear that he did NOT like it and to take it down…which I did. «sigh»

Awww - I'm sorry you had to take it down. I bet it was fascinating.

Thanks. Great info
