The Idea Factory

The Idea Factory is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand The Idea Factory rather than just read about it. In short: The Idea Factory: Bell Labs and the Great Age of American Innovation is a 2012 book by Jon Gertner that describes the history of Bell Labs, the research and development wing of AT&T, as well as many of its personalities, including Claude Shannon and William Shockley. Reception The New York Times said that Gertner's "portraits of Kelly and the cadre of talented scientists who worked at Bell Labs are animated by a jou…

Key takeaways

The Idea Factory belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect The Idea Factory to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of The Idea Factory from memory before moving on to harder problems.

Reference excerpt

The Idea Factory: Bell Labs and the Great Age of American Innovation is a 2012 book by Jon Gertner that describes the history of Bell Labs, the research and development wing of AT&T, as well as many of its personalities, including Claude Shannon and William Shockley.

Reception The New York Times said that Gertner's "portraits of Kelly and the cadre of talented scientists who worked at Bell Labs are animated by a journalistic ability to make their discoveries and inventions utterly comprehensible". The Idea Factory was reviewed favorably by Foreign Policy, the New York Times, the Cleveland Plain-Dealer and others. Three adapted excerpts from the book were published in TIME. Facebook co-founder and chief executive officer Mark Zuckerberg recommended The Idea Factory to his book club in 2015, saying of the choice, "[he is] very interested in what causes innovation — what kinds of people, questions and environments."

Worked examples

Example 1 — a first encounter with The Idea Factory

Start with the simplest possible case. Write down what The Idea Factory 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 Idea Factory 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 Idea Factory 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 Idea Factory

In research: The Idea Factory 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 Idea Factory 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 Idea Factory is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2012 non-fiction books, Bell Labs, Books about scientists, so understanding it makes those chapters shorter.
In everyday life: Look for The Idea Factory 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.
