Reference excerpt

Mary Yvonne Pottenger Hockaday (born 1957) is an American physicist who works at the Los Alamos National Laboratory. She was elected a Fellow of the American Association for the Advancement of Science in 2014 and the American Physical Society in 2022.

Early life and education Hockaday was an undergraduate student in physics at the University of Hawaiʻi at Mānoa. She moved to New Mexico State University for her doctoral research, where she studied the degradation of X-Ray reflectivity from metals due to an intense X-Ray flux.

Research and career In 1986, Hockaday joined Los Alamos National Laboratory. She was appointed a staff member in the Fast Transient Plasma group and developed X-ray diagnostics for the Nevada Test Site. As nuclear testing slowed down, she switched her focus to high-powered lasers. She was one of the first researchers to deploy proton radiography to image the inside of a nuclear explosion, which she achieved using the Los Alamos Neutron Science Center (LANSCE). Hockaday was involved with the development of the Dual-Axis Radiographic Hydrotest Facility (DAHRT). Hockaday was a long-standing member of the Weapons Physics Directorate. She was responsible for developing the inertial confinement fusion campaign. In 2013, Hockaday was named associate director of the Los Alamos National Laboratory. She was responsible for MaRIE (Making, Measuring, and Modeling Extremes), a facility that worked to create a free electron laser. In 2018, Hockaday was made lead of the Nuclear Engineering and Nonproliferation Division. She develops nuclear safeguards and instrumentation to monitor nuclear materials.

Worked examples

Example 1 — a first encounter with Mary Hockaday (physicist)

Start with the simplest possible case. Write down what Mary Hockaday (physicist) 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 Mary Hockaday (physicist) 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 Mary Hockaday (physicist) 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 Mary Hockaday (physicist)

In research: Mary Hockaday (physicist) 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 Mary Hockaday (physicist) 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: Mary Hockaday (physicist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1957 births, 20th-century American physicists, 20th-century American women physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Mary Hockaday (physicist) 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.
