Reference excerpt

John Hamilton Bowie (born 16 July 1938) is an Australian scientist and academic, best known for his contributions to research in the fields of the chemistry of negative ions in the gas phase and of bio-active peptides in skin glands.

Career and Research Bowie was born as the only child of William Hamilton Bowie and Alice Maud Bowie (nee Boyce), educated in Melbourne, and graduated from the University of Melbourne where he obtained an MSc for his work on the colouring matters of Australian plants. In 1961 he started working with Alan Johnson obtained his PhD at the University of Nottingham on the structures of various antibiotics including streptolidine, viomycin, and rhodomycinone, where he came across mass spectrometry for the first time. He subsequently took up an ICI postdoctoral fellowship at the University of Cambridge under Lord Todd. In 1966, he was appointed to a lectureship at the University of Adelaide, rising to become head of department. In 1968 he was awarded the Rennie Memorial Medal for his work on the rearrangement of positively charged organic molecules. In 1974 he was awarded the H. G. Smith Memorial Medal of the Royal Australian Chemical Institute and in 2001 the A.J. Birch medal. In 2006 he received the Thomson Medal. From 1989 to 1992 he was Pro-Vice-Chancellor of the university. In 2017, Bowie was appointed a Member of the Order of Australia for significant service to science in the field of mass spectrometry, and to education as an academic, researcher and author.

Worked examples

Example 1 — a first encounter with John Hamilton Bowie

Start with the simplest possible case. Write down what John Hamilton Bowie 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 John Hamilton Bowie 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 John Hamilton Bowie 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 John Hamilton Bowie

In research: John Hamilton Bowie 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 John Hamilton Bowie 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: John Hamilton Bowie is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1938 births, Academic staff of the University of Adelaide, Alumni of the University of Nottingham, so understanding it makes those chapters shorter.
In everyday life: Look for John Hamilton Bowie 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.
