At the press of a button, the largest machine ever made by humans will come alive. Buried around 100m underground, near Geneva, Switzerland, the Large Hadron Collider is about to make history once again when it restarts in a few weeks time. Thousands of researchers are at work in the center to discover how the world was made and what happened right after the Big Bang. Most of the time, it's the physicists that get all the credit for big breakthroughs. But they couldn't have done it without the IT guys.
