Let’s Begin…

Why does the Earth spin? Does a basketball falling from a spinning merry-go-round fall in a curve, as it appears to, or in a straight line? How can speed be manipulated while spinning? In short, why is the spinning motion so special? Brian Jones details the dizzyingly wide array of ways that spinning affects our lives.
