Henry d'Assumpcao

Henry d'Assumpcao is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Henry d'Assumpcao rather than just read about it. In short: Henrique Antonio (Henry) d'Assumpção (born 9 August 1934) is an Australian electronic engineer, and was Chief Defence Scientist from 1987 to 1990. d'Assumpção joined the Weapons Research Establishment (now known as Defence Science and Technology Group) in 1958 and took up work pioneered by Alan Butement on Barra sonobuoys and later Kariwara towed arrays. He worked his way up the organisation, culminating in the role…

Key takeaways

Henry d'Assumpcao belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Henry d'Assumpcao to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Henrique Antonio (Henry) d'Assumpção (born 9 August 1934) is an Australian electronic engineer, and was Chief Defence Scientist from 1987 to 1990. d'Assumpção joined the Weapons Research Establishment (now known as Defence Science and Technology Group) in 1958 and took up work pioneered by Alan Butement on Barra sonobuoys and later Kariwara towed arrays. He worked his way up the organisation, culminating in the role of Chief Defence Scientist from 1987 to 1990. After leaving the Department of Defence, d'Assumpcao took up a role as professor at the University of South Australia and CEO of the Cooperative Research Centre for Sensor Signal and Information Processing until his retirement in 2000. d'Assumpção was appointed an Officer of the Order of Australia in 1992 in recognition of his service to science and technology. He won the 2003 M. A. Sargent Medal.

Worked examples

Example 1 — a first encounter with Henry d'Assumpcao

Start with the simplest possible case. Write down what Henry d'Assumpcao 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 Henry d'Assumpcao 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 Henry d'Assumpcao 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 Henry d'Assumpcao

In research: Henry d'Assumpcao 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 Henry d'Assumpcao 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: Henry d'Assumpcao is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1934 births, Australian physicists, Chief Defence Scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Henry d'Assumpcao 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.
