What makes trick-or-treaters happy is candy. And more candy is better, right?
Well, it turns out that might not actually be the case. A few years ago researchers did a study on Halloween night where some trick-or-treaters were given a candy bar, and others were given the candy bar and a piece of bubble gum.
When Sandy blew into East Coast communities a year ago, it was flooding that did the most damage.
That's in part because the average sea level has risen over the past century — about a foot along the mid-Atlantic coast. That made it easier for the storm to push the ocean onto the land.
And scientists say there will be many more Sandy-style storms — that is, torrential rain and wind that create heavy coastal flooding — and they'll be more frequent than in the past. But preparing people for that means changing the way they live, and that's proving politically difficult.
Whenever you look at the teeming, rich and oh-so-various world, if you've got the right eyes, if you've got the eyes of a mathematician, you will find patterns — simple, elegant forms hiding in everything you see. Those patterns explain why sugar dissolves in a cup of coffee, why clouds release rain, why a heavy plane can climb into the sky.
