Reference excerpt

Harry Evans Hallam (d. 1977) was a chemist and academic at the University College of Swansea.

Early life and career Hallam spent his early years in East Africa. He attended Ardwyn Grammar School in Aberystwyth before going on to serve in the RAF. He studied chemistry at the University College of Aberystwyth and then undertook a University of London PhD by correspondence while working at the University of Khartoum.

Academic career In 1955 Hallam was appointed to the staff of the Department of Chemistry at University College of Swansea becoming Senior Lecturer in 1964 and Reader in 1970. In 1963, Hallam took a year's sabbatical and became an adviser in physical chemistry at the new University of Nigeria at Nsukka. He had active international collaborations and was presented with a medal by the University of Helsinki in 1973 for his outstanding service and was also a visiting professor at the University of Marburg in 1975. Hallam was known for his work in infrared spectroscopy of the hydrogen bond and as one of the founders of matrix isolation spectroscopy. He died unexpectedly on 14 May 1977.

Personal life Hallam was married to Joan and they had a son called David. He was an active member of the Clyne Chapel, Blackpill.

The Harry Hallam Memorial Fund In his memory, an endowment for an annual lecture to take a "particular account would be taken of Harry’s interest in spectroscopy" was created in 1977 with an appeal made for donations in the Journal of Molecular Structure. The lectureship is administered by the South Wales West Local Section of the Royal Society of Chemistry.

Worked examples

Example 1 — a first encounter with Harry Hallam (academic)

Start with the simplest possible case. Write down what Harry Hallam (academic) 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 Harry Hallam (academic) 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 Harry Hallam (academic) 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 Harry Hallam (academic)

In research: Harry Hallam (academic) 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 Harry Hallam (academic) 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: Harry Hallam (academic) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1977 deaths, Academics of Swansea University, Alumni of Aberystwyth University, so understanding it makes those chapters shorter.
In everyday life: Look for Harry Hallam (academic) 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.
