U.S. Johnson Map Project is a science 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 U.S. Johnson Map Project rather than just read about it. In short: The U.S. Johnson Map Project (JMP) is a not-for-profit organization whose mission is to preserve the works of American publisher Alvin J.

Key takeaways

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

Reference excerpt

The U.S. Johnson Map Project (JMP) is a not-for-profit organization whose mission is to preserve the works of American publisher Alvin J. Johnson, including his atlases and books. The project reflects the work of Ira S. Lourie, who has studied the work of Johnson since 1985. The JMP offers the data collected by the project free to public on its website, JohnsonMapProject.org. Johnson was a prolific publisher of atlases, and his “Johnson’s Family Atlas” was published from 1860 to 1887. Over the 27 years they were published, Johnson used 67 different maps of the United States and its individual states and the 658 variations of those maps in those atlases. The JMP has collected data on these 658 variations, which it presents on its website free of charge. This data is useful in identifying and dating loose Johnson atlas maps that have been removed from atlases. The website includes a “Map Identifier” capacity for this purpose. The website also has a gallery of Johnson's U.S. atlas maps which offers detailed images of each of the 67 maps, which were given to the JMP by The David Rumsey Historical Map Collection. In addition, the JMP has studied the availability of Johnson maps in the market place and has created a “Rarity Index” that dealers and collectors can use to better understand the value of their maps. The development of this “Rarity Index” was presented for review to the Washington Map Society and published in its journal along with a listing of the “rarity” of each of the 658 variations of Johnson's U.S. maps. The JMP also has studied the biography of A.J. Johnson and his role in 19th-century map making. This history is published on the website and documents his role as a book publisher as well as map and atlas publisher.

Worked examples

Example 1 — a first encounter with U.S. Johnson Map Project

Start with the simplest possible case. Write down what U.S. Johnson Map Project claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 U.S. Johnson Map Project 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 U.S. Johnson Map Project 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 U.S. Johnson Map Project

In research: U.S. Johnson Map Project appears in science 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 U.S. Johnson Map Project 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: U.S. Johnson Map Project is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cartography organizations, Cartography stubs, Geographic data and information organizations in the United States, so understanding it makes those chapters shorter.
In everyday life: Look for U.S. Johnson Map Project 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.
