Reference excerpt

Sir Murray Frederick Brennan (born 2 April 1940) is a New Zealand surgeon, oncologist, cancer researcher, and academic. From 1985 to 2006, he was chairman of the surgery department of the Memorial Sloan Kettering Cancer Center in New York City, United States.

Biography Born in the Auckland suburb of Onehunga in 1940, and educated first at Onehunga Primary School. Brennan attended the University of Otago, gaining a BSc in 1962, and MB ChB in 1964. A rugby union player, he played 12 matches for Otago between 1964 and 1965. He also served as president of the Otago University Students' Association. In 1967 he was appointed as an assistant lecturer in physiology and surgery at Otago, and in 1970 he moved to the United States and undertook laboratory and clinical work at Peter Bent Brigham Hospital, Harvard Medical School and the Joslin Research Laboratories. After a period as head of the surgical metabolism section at the National Cancer Institute, he became chief of the gastric and mixed tumor service at the Memorial Sloan Kettering Cancer Center (MSKCC) in New York City in 1981. Between 1985 and 2006 he was chairman of the surgery department at MSKCC. Brennan has authored over 1,000 publications and has served on the editorial board the Australian and New Zealand Journal of Surgery since 1985. He co-founded Dugri Inc. in 2020, where he has worked with Jonathan Lewis, Yotam Dagan and others to help hone the development of next-generation technology platforms for scale in the management of operational stress management and PTSD.

Honours Brennan was awarded an honorary Doctor of Science (DSc) degree by the University of Otago in 1997. In the 2015 New Year Honours, he was awarded one of New Zealand's highest honours when he was appointed Knight Grand Companion of the New Zealand Order of Merit for services to medicine.

Worked examples

Example 1 — a first encounter with Murray Brennan

Start with the simplest possible case. Write down what Murray Brennan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Murray Brennan 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 Murray Brennan 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 Murray Brennan

In research: Murray Brennan appears in physics 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 Murray Brennan 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: Murray Brennan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, Academic staff of the University of Otago, Cancer researchers, so understanding it makes those chapters shorter.
In everyday life: Look for Murray Brennan 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.
