Digital technologies: celebrating 30 years of the World Wide Web

Celebrate the 30th anniversary of the World Wide Web with this special issue, which begins with a feature by Neil Johnson from George Washington University in the US, who describes how physics can fight terrorism by tracking the birth, growth and death of extremist groups who’ve gathered online through social media. There’s also a feature on how computing and simulation have evolved into the “third pillar” of science alongside theory and experiment, while Jess Wade has created a two-page graphic outlining the history of the Web. Finally, try our fun, Internet and Web-themed cryptic crossword.
