Richard Johnsonbaugh

Richard Johnsonbaugh is a astronomy 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 Richard Johnsonbaugh rather than just read about it. In short: Richard F. Johnsonbaugh (born 1941) is an American mathematician and computer scientist.

Key takeaways

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

Reference excerpt

Richard F. Johnsonbaugh (born 1941) is an American mathematician and computer scientist. His interests include discrete mathematics and the history of mathematics. He is the author of several textbooks. Johnsonbaugh earned a bachelor's degree in mathematics from Yale University, and then moved to the University of Oregon for graduate study. He completed his Ph.D. at Oregon in 1969. His dissertation, I. Classical Fundamental Groups and Covering Space Theory in the Setting of Cartan and Chevalley; II. Spaces and Algebras of Vector-Valued Differentiable Functions, was supervised by Bertram Yood. He also has a second master's degree in computer science from the University of Illinois at Chicago. He is currently professor emeritus at De Paul University.

Worked examples

Example 1 — a first encounter with Richard Johnsonbaugh

Start with the simplest possible case. Write down what Richard Johnsonbaugh 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 Richard Johnsonbaugh 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 Richard Johnsonbaugh 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 Richard Johnsonbaugh

In research: Richard Johnsonbaugh 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 Richard Johnsonbaugh 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: Richard Johnsonbaugh is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, 20th-century American mathematicians, 21st-century American mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for Richard Johnsonbaugh 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.
