Reference excerpt

MaryJo Baedecker (born 1941) is an American geochemist. She was named a fellow of the American Geophysical Union in 2011.

Early life In 1941, Baedecker was born in Richmond, Kentucky.

Education Baedecker received a BSc in chemistry from Vanderbilt University, a MSc in chemistry from the University of Kentucky and a PhD in geochemistry from George Washington University.

Career From 1968 to 1973, she was a research scientist at the University of California, Los Angeles, In 1974, she joined the United States Geological Survey (USGS) as a research chemist. Her research focused on the contamination of aquifers by landfill sites. Her research paper on the subject in the journal Groundwater was designated a benchmark in its field by the International Association of Hydrological Sciences. Baedecker played a crucial role in establishing the Toxic Substances Hydrology Program at USGS. She became the chief scientist for hydrology at USGS and leader of the USGS' National Research Program. She retired from the USGS in 2004 but continues to work as a scientist emeritus there. In 2002, she received Distinguished Service Awards from the American Department of the Interior and from the Geological Society of America. In 2010, she received the Meinzer Award.

Worked examples

Example 1 — a first encounter with Mary Jo Baedecker

Start with the simplest possible case. Write down what Mary Jo Baedecker 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 Mary Jo Baedecker 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 Jo Baedecker 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 Jo Baedecker

In research: Mary Jo Baedecker 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 Mary Jo Baedecker 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 Jo Baedecker is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, American geochemists, Fellows of the American Geophysical Union, so understanding it makes those chapters shorter.
In everyday life: Look for Mary Jo Baedecker 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.
