For all of the high and mightiness of this article, this bugged me:
In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?
If a lilypad is 20 square inches (which is probably conservative), and you started with 1 lilypad, after 48 days of doubling it would cover 1.4MILLION square miles. That is 44 times the surface area of Lake Superior.
I get the point of the question, but if you're trying to play "gotcha" on people, at least ask a reasonable question.
