Happy Pi Day

March 14 (3/14) marks Pi Day. For math lovers, it's a chance to celebrate Pi.

Pi represents the ratio of the circumference of a circle to its diameter.

[LiveScience]: Pi is a number that relates a circle's circumference to its diameter. Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That's because pi is what mathematicians call an "infinite decimal" - after the decimal point, the digits go on forever and ever.

Students are usually introduced to the number pi as having an approximate value of 3.14 or 3.14159. Though it is an irrational number, some people use rational expressions, such as 22/7 or 333/106, to estimate pi. (These rational expressions are accurate only to a couple of decimal places.)

Mathematicians and math enthusiasts are interested in calculating pi to as many digits as possible.

Meanwhile, some computer programs have calculated the value of pi to an astounding 62.8 trillion digits. Calculations like these are often unveiled on Pi Day, a pseudo-holiday that occurs every year on March 14 (3/14).

My last name, when written in Greek, begins with π but, of course, with the upper-case (Π).

Many who are familiar with the pronunciation of the letters of the Greek alphabet through math and/or science classes -- or through fraternity or sorority life -- are surprised that several of the letters are pronounced differently in Greek from the way that they learned in class or in Greek life. The letters often make a sound different from that learned in the named circumstances. For instance, π is not pronounced like the English word "pie"; rather, it is pronounced like the word "pea."

For those who are interested, here is a link to the actual sounds (for Greek speakers) of the letters of the Greek alphabet.

Today is our 52nd wedding anniversary & we are going to a nice little town on Wednesday for a day of shopping & a good meal. We will have a piece of🍰 then. This morning we had a great breakfast at a restaurant we haven't eaten in for two years as we went on shutdown the day before our anniversary on 03/13/2020/.

Math is not my "strong suit," but Happy Pi Day to everyone for whom this day is special!
