When I was a kid, I had a passion for card tricks. One day someone showed me a card trick based on a mathematical formula. It was astonishing. He gave me the formula for doing it, but didn’t tell me how it worked, so I set about trying to figure it out for myself. No matter how hard I tried, I just couldn’t see where the formula came from. I even asked a couple of high-powered students at CalTech (California Institute of Technology) for help. They said “Sure. Give us a couple of days and we will get back to you.” I never heard from them again.
Many years late, I did figure it out. I was extremely proud of myself, not because I had solved a very complex problem but because I had solved a very easy one. It just didn’t look easy when I first saw it, and for many years thereafter.
Card tricks still fascinate me, especially those based on mathematical formulas. I will tell you about this one a bit later in this blog. But first I would like to establish why playing cards themselves justly deserve a place on the list of what I like to call “Extraordinary Ordinary Things.”Continue reading Playing Cards—Extraordinary Ordinary Things
