Pi is a name given to the ratio of the circumference of a circle to the diameter. The numerical representation is 3.14. It is acknowledged on March 14 each year (mostly in the US) from a mathematical perspective and also for pies. Have you ever celerated Pi(e) day?
Then again, I'm no mathematician, or scientist, although hubby was, but he never spoke of it when working!
Maths was my least fave subject at School, from Grades 1-10, wasn't needed in my Academic Senior subjects, thank goodness , was total c@&$ at it, hated it, had nil interest in it at all, & was very pleased I failed Junior Maths. Even though I tried hard in the exams, it just made no sense to me whatsoever, & basically, still doesn't. I just don't have the type of brain needed for it!
English & Geography, on the other hand, which I adored, well, 7's each for them, had no problem learning. Although much involved in study of both subjects, the requirements I just 'soaked up like a sponge', & they were the eventual set of knowledge which led me to my lifelong, much loved, career of 45 years!
