It can be of no practical use to know that Pi is irrational, but if we can know, it surely would be intolerable not to know.

Edward Titchmarsh

I don’t remember anyone ever mentioning Pi Day when I was in school, but any excuse to celebrate math sounds like fun. March 14 at 1:59 (a.m. or p.m.) is about as close as the calendar can get to 3.14159…

Here are a few pi-related links you may find interesting:

Math-related quotes from Albert Einstein

Gravitation cannot be held responsible for people falling in love.

How on earth can you explain in terms of chemistry and physics so important a biological phenomenon as first love?

Put your hand on a stove for a minute and it seems like an hour. Sit with that special girl for an hour and it seems like a minute. That’s relativity.

    1. I’d love to hear the story — it sounds intriguing.

      It’s a fun quote. Maybe not much help to a young physics student trying to wrap a confused brain around the behavior of space and time. But lovely fun.

  1. Hi Denise,
    It seems that the comical illustration was given to a girl secretary, Helen Dukas, by Einstein because so many reporters had asked her to explain relativity. The New York Times reporter wrote the first version of it in 1929. Others wrote it and the nice girl became a pretty girl. It is like a long-term game of telephone. Every time some retold the story, it changed a bit.
    I think it is funny that he hired a young lady secretary to answer questions for him. Can you imagine having that job? I agree it is a fun story. It sounded like a Groucho Marx quote to me.
