Pi Day is celebrated on March 14 around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant – the ratio of the circumference of a circle to its diameter – which is approximately 3.14159.

Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.

Pi Day may be a cause for celebration throughout the world but the ides today will bring bad news for a few candidates in our next-door neighbour.

In my workplace, Pi Day is celebrated with a table full of delicious pies and the chance to eat a slice after successfully answering a simple math question.

We don’t celebrate the sciences and important science-y people enough in our society or appreciate their contribution to our lives and our understanding of the world around us, imho.

Happy Pi Boxing Day!

I should have thought that champagne would be more appropriate. Pies are square.

I am reminded on this day, March 16, that the Google Doodle people are a notable exception. They frequently feature scientists, particularly the doubly obscure female ones. Today it is Caroline Herschel.

My favourite irrational number is the Golden Mean or phi. phi = 1+1/phi. Also phi = 2 × sin(54°) = 2 X 0.80901699437 = 1.61803398875

I just like it!

I’m in Hawaii visiting my daughter. We celebrated with paPAYa for breakfast.

Would it be fair to say that Caroline Herschel is to astronomy as Fanny Mendelsohn is to music?

Sorry, I know nothing about Caroline H. But I know the feminists are riight that Fanny M. was overshadowed by her brother. I just listened to a movement from a string quartet by her. It is lovely.
