Martha R. McCartney

Martha R. McCartney 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 Martha R. McCartney rather than just read about it. In short: Martha Rogers "Molly" McCartney is an American physicist known for her work developing electron holography and using it to measure electromagnetic fields at the nanoscale. She is a professor emerita at Arizona State University.

Key takeaways

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

Reference excerpt

Martha Rogers "Molly" McCartney is an American physicist known for her work developing electron holography and using it to measure electromagnetic fields at the nanoscale. She is a professor emerita at Arizona State University.

Education McCartney has a 1982 bachelor's degree from Evergreen State College in Olympia, Washington. She went to Arizona State University for doctoral study, completing her Ph.D. in 1989. Her dissertation, Observations of electron irradiation effects at transition metal oxide surfaces, was supervised by David J. Smith.

Recognition In 2009, McCartney and her coauthors Rafal E. Dunin-Borkowski and Takeshi Kasama were the recipients of the Ernst Ruska Prize of the German Society for Electron Microscopy. McCartney was elected as a Fellow of the American Physical Society (APS) in 2012, after a nomination from the APS Division of Materials Physics, "for outstanding contributions to the development of off-axis electron holography and applications to the quantification of nanoscale electrostatic and magnetic fields".

Worked examples

Example 1 — a first encounter with Martha R. McCartney

Start with the simplest possible case. Write down what Martha R. McCartney 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 Martha R. McCartney 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 Martha R. McCartney 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 Martha R. McCartney

In research: Martha R. McCartney 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 Martha R. McCartney 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: Martha R. McCartney is common in secondary-school and first-year university syllabi. It links to neighbouring topics American physicists, American women physicists, Arizona State University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Martha R. McCartney 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.
