Reference excerpt

Twenty-Four Hours A Day, written by Richmond Walker (1892–1965), is a book that offers daily thoughts, meditations and prayers to help recovering alcoholics live a clean and sober life. It is often referred to as "the little black book." The book is not official ("conference approved") Alcoholics Anonymous literature.

History In 1952, while looking for educational materials for alcoholics, Hazelden President Pat Butler came across a small volume titled Twenty-Four Hours A Day. The author, Richmond Walker of Daytona Beach, Florida, was publishing, selling, and distributing the volume himself. Butler offered to assume publication and distribution of the work. Walker agreed after the General Service Board of Alcoholics Anonymous showed no interest in the undertaking. In May 1954, Hazelden purchased the rights to Twenty-Four Hours A Day. Close to 5,000 copies were sold in the first year. Today, Twenty-Four Hours a Day has sold over eight million copies in 30 countries and is a staple of many twelve-step groups.

Worked examples

Example 1 — a first encounter with Twenty-Four Hours A Day

Start with the simplest possible case. Write down what Twenty-Four Hours A Day 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 Twenty-Four Hours A Day 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 Twenty-Four Hours A Day 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 Twenty-Four Hours A Day

In research: Twenty-Four Hours A Day 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 Twenty-Four Hours A Day 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: Twenty-Four Hours A Day is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1954 non-fiction books, Alcoholics Anonymous, Self-help books, so understanding it makes those chapters shorter.
In everyday life: Look for Twenty-Four Hours A Day 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.
