We've become a nation of wusses. The Chinese are kicking our butt in everything," he added. "If this was in China do you think the Chinese would have called off the game? People would have been marching down to the stadium, they would have walked and they would have been doing calculus on the way down.Gov. Ed Rendell clearly doesn't understand calculus. If he did, then he'd know that calculus was basically invented to describe motion. (He should have read Steven Strogatz's Change We Can Believe In.) Therefore, anyone in motion -- whether walking to the stadium or driving in a SUV with heated leather seats -- is doing calculus.
Let f(x) be differentiable on the open interval (a,b) and continuous on the closed interval [a,b]. Then there is at least one point c in (a,b) such thatThis is the formula for a derivative on an interval. If a and b are the times your car was photographed (at the entrance and exit of the bridge), and f(a) and f(b) are the locations where your car was photographed, then your average speed is f'(c).
If f is continuous on a closed interval [a,b], and c is any number between f(a) and f(b) inclusive, then there is at least one number x in the closed interval such that f(x)=c.This has major implications in integral calculus, but that is not why I am mentioning it.

"The average water footprint per calorie for beef is 20 times larger than for cereals and starchy roots," they note, referring to global averages, not U.S.-specific figures. "The water footprint per gram of protein for milk, eggs and chicken meat is 1.5 times larger than for pulses," a group of legumes that includes peas, beans and lentils.Perhaps the LA Times reported GLOBAL (not US) water intensity in US units of gallons? The article wasn't clear.
