Π Day 3.14
Today is International Pi Day. (It almost got by me.) Pi is a mathematical constant that makes possible the calculation of the area of a circle, the volumn of a cylindar , the volumn and suface of a sphere and their derivatives. How life and would be so different without Pi.
The famous Greek mathematician, Archimedes is credited with discovering Pi.
Pi is an approximation. Here is Pi worked out to 2000 places after the decimal point.
If you do not believe me, work it out for yourself! It seem it is a number that is never exact no matter how far you calculate it. Those that care about such things are forever using computers to try to complete the calculations.
This is a good day to think about this mathematical constant 3.14 or 22/7ths and how usefull it is. It is a good day to talk to children about the wonders and mysteries of numbers and mathematics.
Think also of it as a religious sign. Those who think the Universe is one of order and a design with a possible Designer (God) might point to this as a "proof" that we live in an orderly Universe. The mathematical genius, Srinivasa Ramanujan, a devote Hindu , espresss it this way, "An equation for me has no meaning, unless it represents God." This is what is know as the argument from design for the existence of God. I am unconvinced but it has been put forward through the ages. That does not mean I do not find mathematical order in the Universe excitingly mysterious.
I am fascinated with "magical" numbers. The one that I believe shapes our mind, or is an aspect of our mind that shapes our reality, is 3. How often do we see things in threes. There is the Christian Trinity, Marxist, dialectic, Freudian, Id, ego, superego. It seems we most easily make sense of our world or remember things most easily if we group them in threes. You may have your favourite number. Three works for me and my analytical mind.
Happy Pi Day!
