A friend linked to this on Facebook, asking: "Can you explain a hard idea using the ten hundred most common words?" So I decided to try to explain calculus. What I wrote seems pretty bad. My explanation from October seems much clearer. But I thought I'd share.

Will you try it with a math topic? (I'd love to see a better description of calculus.) Here are some of the words you can't use: math, slope, steepness, circle, curve, and infinity.

About calculus:Some lines are straight. Some are not. It's easy to think about how much a straight line goes up as it goes over. It's harder to think about that when the line is not straight. Two guys figured out some good ideas to help think about this around 1670. They cared because it would help people think about the world. How fast do things fall? How does light turn when it goes through round glass? How do we find the best way to do something? Their ideas also help us think about areas that don't have straight edges.

To think about these things, we need to think about something bigger than any number, about two things closer than any number can say, and about cutting smaller parts than any number can say. Thinking about this in just right ways takes some hard thinking.

I did one for statistics. It is very hard to do!

ReplyDeleteWhen you have lots of numbers that stand for things in the world, you want to make sense of what those numbers are mean, what look or direction is shown by those numbers or find out if those numbers are strange in the situation given.

Lovely!
