That helps explain why Bolt's legs move fast enough to be a blur. When people run, they are essentially bouncing though the air from one leg to another, says Daniel Lieberman, a professor of biological anthropology at Harvard University who studies how and why the human body looks and works as it does. What determines how fast people go is their stride length - a function of how long the legs are, how powerfully they push off into a stride and how far forward the body jumps - and their stride rate, which is how fast they can propel their legs...

And if Israel were to opt for trying to destroy Tehran's nuclear facilities through a series of air strikes, then the presence of the sophisticated Russian S-300 missile system in Iran would considerably raise the risk to Israeli pilots. Unfortunately for Israel, however, there may be little it can do to shape Moscow's Iran policy for the simple reason that Israel is not a major factor...
