Really High Pressures

Deep down in the earth are tremendously high pressures. What happens under high pressure is not the same as what happens at lower pressures. Lawrence Livermore National Laboratory physicists are using an ultra fast laser based technique they dubbed nanoshocks for something entirely different. In fact, the nanoshocks have such a small spatial scale that scientists can use them to study shock behavior in tiny samples such as thin films or other systems with microscopic dimensions (a few tens of micrometers). In particular they have used the technique to shock materials under high static pressure in a diamond anvil cell.
