Irrational numbers are interesting bit of mathematics. Those numbers can't be written in fractions. Their decimal goes on like forever without repeating. Pi, e, Golden Ratio are some of well known irrational numbers. And Pi is the subject of interest here. "Pi is an infinite, non-repeating decimal -- meaning that every possible number combination exists somewhere in pi. Converted into ASCII text, somewhere in that infinite string of digits is the name of every person you will ever love, the date, time, and manner of your death, and the answers to all great questions of the universe."
