Among other things that I do, I am an engineer. (Yes, I am doomed to a life of social ineptitude, see: this.) I am fascinated by all things mechanical and electrical. Therefore, the value represented by the Greek letter π is of special interest (and use) to me.
And, as it turns out, there is a day set aside each year (in fun) to remember π — March 14. Therefore, at 1556h today, I am taking a moment to celebrate six significant figures of π.
Happy π Day!
