The Unbelievable Accuracy of the Monte Carlo Method

The year was 1945, the year I was born. That in itself is of great significance to me.  However, it was a momentous year in history. World War II came to its merciful end and the development of the first electronic computer – the ENIAC—was nearing completion. At a post-war Los Alamos National Laboratory (LANL), mathematician Stanislaw Ulam envisioned the possibilities of reviving statistical techniques that would have a...

Mars Science Laboratory Curiosity – ChemCam

How do you run chemical tests at a geologic site millions of miles away from you to see what the rocks and soil are made of? Curiosity’s new instrument ChemCam, developed at Los Alamos National Laboratory, is designed to determine how much light is emitted at each frequency by a geologic sample when it’s heated by a laser beam. Since different materials have different light-emission patterns, measuring the patterns shows what materials emitted them.
