Greg Lindsay

Greg Lindsay is a science 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 Greg Lindsay rather than just read about it. In short: Gregory John Lindsay AO (born 1949) is an Australian public speaker who was until 2018 the Executive Director of the Australian think tank the Centre for Independent Studies (CIS), which he founded in 1976 when a young mathematics teacher in the western suburbs of Sydney. CIS has become influential in Australia and New Zealand.

Key takeaways

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

Reference excerpt

Gregory John Lindsay AO (born 1949) is an Australian public speaker who was until 2018 the Executive Director of the Australian think tank the Centre for Independent Studies (CIS), which he founded in 1976 when a young mathematics teacher in the western suburbs of Sydney. CIS has become influential in Australia and New Zealand.

Biography Lindsay initially studied agricultural science at the University of Sydney, but found that this was not his real interest and instead obtained secondary teaching qualifications in mathematics at Sydney Teachers' College. A short four-year stint at Richmond High School coincided with further study at Macquarie University in philosophy culminating in graduating with a BA majoring in philosophy in 1977. The CIS's first public events were also held at Macquarie in October 1976 and in April 1977. He was made an Officer of the Order of Australia (AO) in 2003 for his contribution to education and public debate. In 2006 he was elected President of the Mont Pelerin Society for a two-year term at its general meeting in Guatemala. He was elected to the Council of Macquarie University for a term from 1 January 2008.

Worked examples

Example 1 — a first encounter with Greg Lindsay

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

In research: Greg Lindsay appears in science 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 Greg Lindsay 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: Greg Lindsay is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1949 births, Australian libertarians, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Greg Lindsay 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.
