I am ordinary. If we walked pass each other on the street you wouldn’t have noticed me at all. If I had a colour it would have been transparent. If I had a sound it would have been muffled. Sometimes I wondered what the point is, a timid life as it is, but then I learned the phrase ‘ mathematical certainty’, which led me to a different world. What a wonderful phrase and expression it is, ‘How certain are you?’ ‘ Mathematically certain’. Wouldn’t it have been nice if it can be bought off the shelf and used in life?
