These include organelles-little factories like energy-producing mitochondria-and tiny molecular machines like ATP synthase, whose rotor and shaft spin at up to 300 rpm to produce ATP, the molecules that transmit energy in our cells. The interior of our cells are also filled with all kinds of molecules randomly colliding at tremendous speeds. Water molecules, for example, zigzag at the astonishing speed of over 1 thousand miles an hour (although they only go about 4...
