4 The World Wide Web was born at CERN

Nobody knows where fundamental research will lead. Famously, Tim Berners-Lee invented the World Wide Web in 1989 at CERN, as a tool to allow scientists around the world to share data.

The complex instruments developed for particle physics, at CERN and other similar facilities, have spawned numerous other uses, including PET scans, the most common tool used to diagnose cancers.

CERN shares its knowledge openly. Gianotti used the analogy of the history of light to explain the role of fundamental, open-ended scientific research: if we had focused only on the business case for bigger and brighter candles, we would never have made the transformative leap to electrical lighting.
