Connect Laura J. Crossey to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Laura J. Crossey from memory before moving on to harder problems.

Reference excerpt

Laura J. Crossey is an American hydrologist and geochemist and Distinguished Professor of Earth and Planetary Sciences at the University of New Mexico (UNM). Crossey is part of UNM's Sustainable Water Resources Grand Challenge team, which studies water and climate in New Mexico and other arid regions. She has studied springs and groundwater in areas including the Western Desert of Egypt, Australia's Great Artesian Basin, Tibet, the Middle Rio Grande Basin and the Grand Canyon.

Early life and education Laura Jones Crossey grew up in Deerfield, Illinois. She attended Colorado College, earning her BA in geology in 1977. She completed a master's in science at Washington University in St. Louis in 1979, working on trace elements in basalts as part of the Terrestrial Basaltic Volcanism project with Larry Haskin. She earned her PhD degree in geology in 1985 at the University of Wyoming, working with Ronald C. Surdam. Crossey's dissertation addressed The Origin and Role of Water-soluble Organic Compounds in Clastic Diagenetic Systems.

Career Crossey joined the Earth and Planetary Sciences department at the University of New Mexico (UNM) in 1985. She was the second woman to be hired by the department, the first woman to become tenured in the department, and the first female chair of the department (2013–2016). She has served as Associate Dean for Academic Affairs (1997–2000) at UNM and as Acting Associate Dean for Research at UNM (2017–2018). As Dean of Research, she helped to arrange a climate-controlled home for the paleontology collection, then housed in Northrop Hall, later the Natural History Science Center. As of 2021, Crossey was named a Distinguished Professor of Earth and Planetary Sciences at the University of New Mexico. Crossey is active in science education and outreach at all levels and works to increase science participation by members of under-represented groups. Crossey has been involved with numerous scholarly and professional organizations, including the New Mexico Governor's committee to develop Science Standards, the Global Water Institute at Ohio State University, the state-wide New Mexico Alliance for Minority Participation, and the international Association for Women Geoscientists.

Worked examples

Example 1 — a first encounter with Laura J. Crossey

Start with the simplest possible case. Write down what Laura J. Crossey 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 Laura J. Crossey 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 Laura J. Crossey 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 Laura J. Crossey

In research: Laura J. Crossey 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 Laura J. Crossey 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: Laura J. Crossey is common in secondary-school and first-year university syllabi. It links to neighbouring topics American hydrologists, Colorado College alumni, Fellows of the American Association for the Advancement of Science, so understanding it makes those chapters shorter.
In everyday life: Look for Laura J. Crossey 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.
