It sounds unbelievable, but it all started only 25 years ago this week. On a March day in 1989, Sir Tim Berners-Lee, a British computer scientist, established the first connection of his brainchild called the World Wide Web – a system for publishing information over the internet.  It was an idea that would change the world and life as we know it. Berners-Lee worked at CERN – the European Organization for Nuclear Research near Geneva, Switzerland – and his intention was to help itinerant academics from all over the world run a complicated particle accelerator, the Large Hadron Collider. These scientists were eager to share information – data and test results – but had plenty of roadblocks. Berners-Lee’s proposal specified a set of technologies that would help overcome that; however, his initial proposal was not immediately accepted. Perseverance is what made Tim successful: by October 1990 he had particularized three essential technologies that remain today the foundation of the Web, visible on any Web browser: HTML: HyperText Markup Language is the publishing format for the Web that includes the function of formatting documents and link to other documents and resources. URI: Uniform Resource Identifier is a sort of “address”, unique to each resource on the Web. HTTP: Hypertext Transfer Protocol allows for the retrieval of linked sources from across the Web. By the end of 1990, the first Web page was served. By 1991, people outside of CERN were able to join the community. Perhaps the most important thing in the history of technology is set on April 1993 when CERN announced that the World Wide Web technology would be available for anyone to use, for free. Today the World Wide Web is the most powerful communication medium we know. Whether we teach and...
