Reference excerpt

Joanne Etheridge is an Australian physicist. She is Director of the Monash Centre for Electron Microscopy and Professor in the Department of Materials Science and Engineering at Monash University.

Academic career Etheridge graduated with a BSc from the University of Melbourne and a PhD in physics from RMIT University in 1993. In 1994 she moved to the University of Cambridge as Rosalind Franklin Research Fellow, Newnham College and in 1997 became a senior research associate in the Department of Materials Science and Metallurgy there. From 1999 to 2003 she was Royal Society University Research Fellow in the same department. From 2005 to 2008 she was also a visiting professor at the Brockhouse Institute at McMaster University. She returned to Monash University in Melbourne to set up and lead the Monash Centre for Electron Microscopy, where she has pioneered electron diffraction and microscopy techniques and ultra-high resolution electron microscopy in Australia. As of 2021 she is on the Editorial Board of the international journal, Ultramicroscopy.

Awards and recognition Etheridge won the University of Cambridge's K. M. Stott Prize in 1995 and the John Sanders Medal awarded by the Australian Microscopy and Microanalysis Society in 2016. In 2012 she presented the Lloyd Rees Lecture of the Australian Academy of Science. In 2019 she was elected Fellow of the Australian Academy of Science. In 2022 she was named the Australian Research Council Georgina Sweet Australian Laureate Fellow. In 2024, she was awarded the Australian Institute of Physics' Walter Boas Medal for Excellence in Research, for her "development of electron scattering methods to determine the structure of condensed matter at the atomic scale and the application of these methods to understand structure–property relationships in functional materials".

Worked examples

Example 1 — a first encounter with Joanne Etheridge

Start with the simplest possible case. Write down what Joanne Etheridge 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 Joanne Etheridge 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 Joanne Etheridge 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 Joanne Etheridge

In research: Joanne Etheridge 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 Joanne Etheridge 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: Joanne Etheridge is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of McMaster University, Academic staff of Monash University, Australian physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Joanne Etheridge 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.
