From PBS and NOVA: Are there physical limits to how fast humans can go? David Pogue wants to find out how much we can tweak physiology and engineering to move humans and machines even faster. He investigates everything from lightning-fast electric muscle cars to ultra-sleek sailboats to ultra-fast cameras and quantum teleportation. But faster is also about efficiency and the science of optimization: getting things done in less time. From the floor of the New York Stock Exchange to UPS headquarters and inside a packed 737, Pogue's quest for ultimate speed limits takes him to unexpected places where he comes face-to-face with the final frontiers of speed. NOVA also explores important questions: Is it possible to go too fast? Have we hit a point where innovation outpaces our ability to keep up?
