Reference excerpt

Peter Fabbri Langman (born February 20, 1960) is an American counseling psychologist and author. He is a known expert on school shooters.

Professional career Langman received his B.A. in psychology from Clark University, his M.A. in counseling psychology from Lesley College, and his Ph.D. in counseling psychology from Lehigh University. In 2009, he published his research on ten school shooters based on the analysis of the Columbine High School massacre, the Virginia Tech shooting, the Red Lake shootings, the Thurston High School shooting, the 1998 Parker Middle School dance shooting, the 1998 Westside Middle School shooting, the 1997 Heath High School shooting, and the 1997 Bethel Regional High School shooting. Langman's book Why Kids Kill: Inside the Minds of School Shooters has been translated into German, Finnish, and Dutch. When the book had been found in the Munich shooter's home as well as in the Arapahoe High School shooter's home, a discourse began regarding whether the shooters had used the book as inspiration or for looking for a role model, someone to emulate. In 2015, he continued his research by extending the number of analysed school shooters from ten to 48 and published the book School Shooters: Understanding High School, College, and Adult Perpetrators. On the website Psychology Today, Langman hosts a blog, "Keeping Kids Safe," but it has not been updated since 2016. [1]

Worked examples

Example 1 — a first encounter with Peter F. Langman

Start with the simplest possible case. Write down what Peter F. Langman claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Peter F. Langman 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 Peter F. Langman 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 Peter F. Langman

In research: Peter F. Langman appears in astronomy 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 Peter F. Langman 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: Peter F. Langman is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960 births, 20th-century American psychologists, 21st-century American psychologists, so understanding it makes those chapters shorter.
In everyday life: Look for Peter F. Langman 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.
