Finding one of the building blocks of the universe is a tough act to follow.

That's the task confronting Fabiola Gianotti when she takes over as head of CERN, the Geneva-based atom-smasher that discovered the Higgs boson particle and landed the Nobel Prize in physics for the scientists who predicted its existence.

Gianotti led one of two experiments that discovered the particle that helps physicists explain the existence of mass. She will be the first woman to head the European Organization for Nuclear Research, an organization with an annual budget of 1.1 billion Swiss francs ($1.1 billion). That's one cappuccino a year for every European citizen, said Gianotti, a 54-year-old Italian.
