Reference excerpt

The Meaning of the 21st Century: A Vital Blueprint for Ensuring Our Future is a 2006 nonfiction book by British technology consultant James Martin.

Synopsis It assesses technological challenges, dangers and opportunities facing the human race. The book lists and proposes solutions for 17 interlocked upcoming "megaproblems". Topics include nanotechnology, artificial intelligence, climate change and terrorism. Martin asserts that many global problems have been worsened by past technologies, but could be addressed by new ones. For example, he advocates for "electronic brain appendages" to help think through to a solution to problems such as global warming.

Film Martin released a film based on the book, narrated by one of his Bermudan neighbors, Hollywood actor Michael Douglas.

Worked examples

Example 1 — a first encounter with The Meaning of the 21st Century

Start with the simplest possible case. Write down what The Meaning of the 21st Century 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 The Meaning of the 21st Century 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 The Meaning of the 21st Century 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 The Meaning of the 21st Century

In research: The Meaning of the 21st Century 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 The Meaning of the 21st Century 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: The Meaning of the 21st Century is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2006 non-fiction books, Futures studies stubs, Futurology books, so understanding it makes those chapters shorter.
In everyday life: Look for The Meaning of the 21st Century 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.
