Explanation of Pi by Mr.Finch on Person of Interest

Mr. Finch, the main character at Person of Interest, acted as a substitute teacher and wrote on the chalkboard 3.1415926535. Then he asked the students, “What does this mean?” However, in the movie, nobody answered. Then Mr. Finch responded to the question himself, saying:

Pi, the ratio of the circumference of a circle to its diameter — 3.1415926535 — is just the beginning. It keeps going forever without ever repeating, which means that contained within this string of decimals is every other number; your birth date, the combination to your locker, your social security number, etc. It’s all in there somewhere. And if you convert these decimals into letters, you would have every word that ever existed in every possible combination; the first syllable you spoke as a baby, the name of your latest crush, your entire life story from beginning to end, and everything we ever say or do. All of the world’s infinite possibilities rest within this one simple circle. Now, what will you do with that information; what it’s good for? Well, that would be up to you!

Although that scene was actually inaccurate, I loved it. This scene is beautiful because most teachers in the world struggle to be as good and as interesting of a teacher as Mr. Finch is here. His knowledge about the subject expands the discussion beyond the textbooks and keeps the students focused throughout the lecture.
