The second strongest in the world and not the strongest.
Recently, the scientists examining nuclear weapons defined the e-BOMB or
The first virtual atomic bomb.
As part of a secret program by the Department of Atomic Energy in Los Alamos, edited

In the world, ASCI White has been proven so far to be able to imitate events
which occur during a nuclear explosion. This allows scientists a way to examine the

The researchers prepared the code to run the experiment for seven months. after the

The Los Alamos simulation was run remotely from Los Alamos on the computer
in Livermore. "It worked almost as if we were sitting in front of a local supercomputer," he said
Jim Dennskiold, Los Alamos spokesman.
To test the reliability of the results, the scientists compared them with data
From real underground experiments. "The simulation followed the physical data

required enormous computing power," says Dennskjöld. "ASCI White is a master

To accelerate research in many fields, from medicine to weather forecasting.
