Patrick O'Sullivan (author) belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Patrick O'Sullivan (author) to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Patrick O'Sullivan is an Irish-British scholar and author of works in the field of Military geography. His works include, The Geography of Warfare and The Geography of War in the Post-Cold War World. In his book Geopolitics (1986), O'Sullivan makes a geographically-based case against the proliferation of nuclear weapons during the Cold War, arguing that nuclear weapons pose a threat primarily because they reduce the significance of both physical distance and national borders, which would otherwise function as deterrents to the likelihood of direct military engagement. O'Sullivan has also written on the social scientific study of railway transportation in Britain as well as an autoethnographic Cultural Geography essay discussing the relevance of expatriate identity. In 1994 he began teaching at Florida State University. He currently holds the status of professor emeritus. His academic writing focuses on regional geography and contains aspects of behavioral geography. Patrick O'Sullivan passed away in 2026 in Tallahassee, Florida.

Worked examples

Example 1 — a first encounter with Patrick O'Sullivan (author)

Start with the simplest possible case. Write down what Patrick O'Sullivan (author) 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 Patrick O'Sullivan (author) 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 Patrick O'Sullivan (author) 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 Patrick O'Sullivan (author)

In research: Patrick O'Sullivan (author) 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 Patrick O'Sullivan (author) 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: Patrick O'Sullivan (author) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alumni of the London School of Economics, British geographers, Florida State University faculty, so understanding it makes those chapters shorter.
In everyday life: Look for Patrick O'Sullivan (author) 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.
