Reference excerpt

Worldchanging: A User's Guide for the 21st Century is a book about environmental concerns and practical actual responses. It is a compendium of the solutions, ideas and inventions emerging today for building a sustainable, livable, prosperous future. In November 2006, Worldchanging published a survey of global innovation, with a foreword by Al Gore, design by Stefan Sagmeister and an introduction by Bruce Sterling. It has received praise, was a winner of the 2007 "Green Prize" for sustainability literature, and is being translated into French under the title Change Le Monde, German and several other languages. Harry N. Abrams, Inc., the publisher of the hardcover edition, listed it among their 50 best selling titles in July 2008.

Awards The book was mentioned by BusinessWeek as one of the "Best Innovation and Design Books for 2006".

Reprinting The updated version was published April 1, 2011, called Worldchanging, Revised Edition: A User's Guide for the 21st Century ISBN 978-0-8109-9746-2. Alex Steffen is the author, Bill McKibben wrote the Introduction, and Van Jones wrote the Foreword. Sagmeister Inc. was the designer.

Worked examples

Example 1 — a first encounter with Worldchanging (book)

Start with the simplest possible case. Write down what Worldchanging (book) 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 Worldchanging (book) 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 Worldchanging (book) 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 Worldchanging (book)

In research: Worldchanging (book) 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 Worldchanging (book) 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: Worldchanging (book) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2006 non-fiction books, Environment book stubs, Environmental social science, so understanding it makes those chapters shorter.
In everyday life: Look for Worldchanging (book) 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.
