3.14 pi

  Today March 14th is white day. This day men give women chocolate or something like that in return for Valentine’s Day.

 It is said that White day started in Japan. This event is held around east Asia, but not America or Europe.

 Moreover today 3.14 is important day for all people. It’s pi day. Pi is the ratio of circumference to diameter. We’re taught about pi in elementary school. But most people don’t know how important pi is. Pi appears all over mathematics. It has a lot of expression.

 Pi is irrational number. Most people memorize pi just as 3.14. When I was a student in elementary school, I memorized pi more than 60 digits. I remember it’s numbers for now.

 I majored in Mathematics in University and I graduated Master’s course of mathematical sciences. But now I’ve forgotten a lot about mathematics.

 We have to live day by day. Now the important thing for me is to work hard every day :P
