The Web Turns 20: Web Science Reveals Human Interactions, Part 4 of 4

In this fourth article of a four-part series commemorating the World Wide Web's 20th birthday, Tim Berners-Lee tells Scientific American editor Mark Fischetti that we still have a lot to learn about the Web's design, operation and impact on society

Editor's Note: The World Wide Web went live 20 years ago this month, on a single computer in Geneva, Switzerland. For the anniversary the Web's inventor, Tim Berners-Lee, has written an exclusive article for Scientific American. In it he confronts various threats that could ruin the Web, and explains why preserving the basic principles that have allowed the Web to flourish is essential to preventing its destruction. While preparing the article, Berners-Lee also spoke to Scientific American about emerging Web capabilities that could change how the online and physical worlds work. This four-part series covers some of the most intriguing, including the power of linked data, social machines, free bandwidth to the masses, and Web science. Indeed, the Web is thriving—a recent cover story in Wired magazine to the contrary notwithstanding. Scientific American editor Mark Fischetti tackles the differences between the two magazine's treatments in his blog, "The Web is (Not) Dead."


The Web is 20 years old this month. We all know how it works, what it can do and what it can't do, right? Hardly.

"The Web's remarkable progress to date has been quite gratifying to me," says Tim Berners-Lee, who invented the Web and first took it live in December 1990. "But the Web is by no means finished. Every bit of past and future advancement rests on two things: technological protocols and social conventions. The protocols, like HTTP and HTML, determine how computers interact. Social conventions, such as the incentive to create links or the rules of engagement on a social networking site, are about how people like to, and are allowed to, interact. We still know surprisingly little about these technical and social mechanisms."

Berners-Lee says we have only scratched the surface of what could be realized with deeper scientific investigation into the Web's design, operation and impact on society. "Robust technical design, innovative business decisions and sound public policy judgment all require that we are aware of the complex interactions between technology and society," Berners-Lee says. This awareness will come from Web science, which Berners-Lee hopes can improve "the science and engineering of this massive system for the common good."

Several years ago MIT and the University of Southampton in the U.K. created the Web Science Trust to advance Web science as a new academic discipline. The organization brings together an international advisory council of distinguished computer scientists, social scientists and legal scholars. Their goal is to create an intellectual foundation, educational atmosphere and resource base that help researchers build up a new science of the Web.

To learn about threats that could ruin the Web, and what Berners-Lee thinks should be done to prevent them, see "Long Live the Web."

Mark Fischetti was a senior editor at Scientific American for nearly 20 years and covered sustainability issues, including climate, environment, energy, and more. He assigned and edited feature articles and news by journalists and scientists and also wrote in those formats. He was founding managing editor of two spin-off magazines: Scientific American Mind and Scientific American Earth 3.0. His 2001 article “Drowning New Orleans” predicted the widespread disaster that a storm like Hurricane Katrina would impose on the city. Fischetti has written as a freelancer for the New York Times, Sports Illustrated, Smithsonian and many other outlets. He co-authored the book Weaving the Web with Tim Berners-Lee, inventor of the World Wide Web, which tells the real story of how the Web was created. He also co-authored The New Killer Diseases with microbiologist Elinor Levy. Fischetti has a physics degree and has twice served as Attaway Fellow in Civic Culture at Centenary College of Louisiana, which awarded him an honorary doctorate. In 2021 he received the American Geophysical Union’s Robert C. Cowen Award for Sustained Achievement in Science Journalism. He has appeared on NBC’s Meet the Press, CNN, the History Channel, NPR News and many radio stations.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
