Reference excerpt

This Is for Everyone is a memoir by Tim Berners-Lee, the inventor of the World Wide Web, co-written by Stephen Witt and published in 2025. The United States edition has the added subtitle The Unfinished Story of the World Wide Web. It provides a first hand history of the invention and evolution of the World Wide Web, how the World Wide Web triggered a slew of other major changes, including the birth of e-commerce, browser wars, progression of search engines, dot-com bubble, the spread of social media, transition of the web from personal computers to mobile devices, and the emergence of AI. It also contains Berners-Lee's prescriptions for a better internet, especially on how people can reclaim control over their digital lives. The first part of the book contains details about his childhood and upbringing in London, his student days including those at the University of Oxford and early career first at Plessey, a British electronic company and then at CERN. The book was written with ghost-writer Stephen Witt.

Worked examples

Example 1 — a first encounter with This Is for Everyone

Start with the simplest possible case. Write down what This Is for Everyone claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to This Is for Everyone before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about This Is for Everyone ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of This Is for Everyone

In research: This Is for Everyone appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses This Is for Everyone in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: This Is for Everyone is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2020s memoirs, 2025 English-language non-fiction books, 2025 non-fiction books, so understanding it makes those chapters shorter.
In everyday life: Look for This Is for Everyone outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
