If you love math, you are a geek — with stock options in your future, but no cheerleaders. So getting a child to love mathematics is a questionable gift — are we really doing them a favor? Recently, a highly placed friend of mine asked me to look into it — not merely as getting a couple of kids interested in math, but as a general educational effort in the country. Once it becomes a general phenomenon, math whizkids might enjoy the same level of social acceptance and popularity as, say, athletes and rock stars. Wishful thinking? May be…
I was always among people who liked math. I remember my high school days where one of my friends would do the long multiplication and division during physics experiments, while I would team up with another friend to look up logarithms and try to beat the first dude, who almost always won. It didn’t really matter who won; the mere fact that we would device games like that as teenagers perhaps portended a cheerleader-less future. As it turned out, the long-multiplication guy grew up to be a highly placed banker in the Middle East, no doubt thanks to his talents not of the cheerleader-phobic, math-phelic kind.
When I moved to IIT, this mathematical geekiness reached a whole new level. Even among the general geekiness that permeated the IIT air, I remember a couple of guys who stood out. There was “Devious” who also had the dubious honor of introducing me to my virgin Kingfisher, and “Pain” would drawl a very pained “Obviously Yaar!” when we, the lesser geeks, failed to readily follow a his particular line of mathematical acrobatics.
All of us had a love for math. But, where did it come from? And how in the world would I make it a general educational tool? Imparting the love math to one kid is not too difficult; you just make it fun. The other day when I was driving around with my daughter, she described some shape (actually the bump on her grandmother’s forehead) as half-a-ball. I told her that it was actually a hemisphere. Then I highlighted to her that we were going to the southern hemisphere (New Zealand) for our vacation the next day, on the other side of the globe compared to Europe, which was why it was summer there. And finally, I told her Singapore was on the equator. My daughter likes to correct people, so she said, no, it wasn’t. I told her that we were about 0.8 degrees to the north of the equator (I hope I was right), and saw my opening. I asked her what the circumference of a circle was, and told her that the radius of the earth was about 6000km, and worked out that we were about 80km to the north of the equator, which was nothing compared to 36,000km great circle around the earth. Then we worked out that we made a 5% approximation on the value of pi, so the correct number was about 84km. I could have told her we made another 6% approximation on the radius, the number would be more like 90km. It was fun for her to work out these things. I fancy her love for math has been augmented a bit.
