Roger Lough

Roger Lough is a chemistry 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 Roger Lough rather than just read about it. In short: Roger Lough is an Australian Defence scientist. He was Chief Defence Scientist from 2003 to 2008.

Key takeaways

Roger Lough belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Roger Lough to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Roger Lough from memory before moving on to harder problems.

Reference excerpt

Roger Lough is an Australian Defence scientist. He was Chief Defence Scientist from 2003 to 2008. Prior to this appointment he had been director of the Platform Sciences Laboratory within the Defence Science and Technology Organisation (DSTO) since January 2002. Lough first joined DSTO's predecessor Weapons Research Establishment (WRE) as a technical assistant, then studied at the University of Adelaide, earning his B.Sc. in 1971 and Ph.D. in 1974. Lough's early research at WRE was in the field of rocket propulsion for tactical weapons, including a Harkness Fellowship placement in the US, then from 1983 as Attaché, Defence Research and Development in Washington D.C. He returned to Australia in 1987 to lead the Guided Weapons Division, followed by posts to Aircraft Systems Division, Air Operations Division, Land, Space & Optoelectronics Division then Land Operations Division. Lough took the post of First Assistant Secretary Science Policy in 2000, then Director Aeronautical and Maritime Research Laboratory from January 2002 which became Director Platforms Sciences Laboratory in July 2002. He was promoted to Chief Defence Scientist in September 2003. After retiring from DSTO, Lough remained interested in Defence Science. He took up the role of Chair of the Defence Science Institute and a member of the Defence Council of Victoria.

Worked examples

Example 1 — a first encounter with Roger Lough

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

In research: Roger Lough appears in chemistry 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 Roger Lough 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: Roger Lough is common in secondary-school and first-year university syllabi. It links to neighbouring topics Australian chemists, Chief Defence Scientists, Fellows of the Australian Academy of Technological Sciences and Engineering, so understanding it makes those chapters shorter.
In everyday life: Look for Roger Lough 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.
