Key takeaways

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

Reference excerpt

Thomas Nathaniel Hibbard (March 14, 1929 – February 11, 2016) was an American mathematician and computer scientist. Thomas N. Hibbard received the B.S. degree in physics from Pacific University, Forest Grove, OR, in 1951, the M.S. degree in mathematics from the University of Illinois, Urbana, in 1954, and the Ph.D. degree in mathematics from the University of California, Los Angeles, in 1966. From 1955 to 1958 T. N. Hibbard was a Scientific Programmer at the RAND Corporation, Santa Monica, CA, programming the JOHNNIAC, an early computer built by Rand, and from 1959 to 1965 a member of the research staff of the System Development Corporation, Santa Monica, CA, where he worked with Seymour Ginsburg and Joseph Ullian in automata theory and formal languages. Following a three-year visiting faculty appointment at the Catholic University of Salta, Argentina, he joined the University of Southern California, Los Angeles, as an assistant professor of Computer Science in 1970. He conducted research in searching, sorting, and data structures, helping to pioneer the field of analysis of algorithms.[H62][H63] In 1974, he started research with his then faculty colleague Armin B. Cremers, initiating the theory and applications of data spaces.[CH] In February 1976, he joined the staff of the Jet Propulsion Laboratory, Pasadena, CA, working on the Voyager, IRAS and Galileo project until his retirement from JPL in 1986. At that time, he joined the Information Sciences Institute (ISI), Marina del Rey, CA, and did experimental research on parallel computing until 1989, when he returned to Salta, Argentina, to teach at the National University (UNSA).

Contributions to Computer Science Hibbard was a co-inventor of the binary search tree. He was the first to propose the so-called Hibbard deletion for binary search trees, in which the node to be deleted is replaced by its successor. Hibbard proposed one of several widely cited increment sequences for the Shellsort algorithm.

Worked examples

Example 1 — a first encounter with Thomas N. Hibbard

Start with the simplest possible case. Write down what Thomas N. Hibbard 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 Thomas N. Hibbard 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 Thomas N. Hibbard 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 Thomas N. Hibbard

In research: Thomas N. Hibbard 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 Thomas N. Hibbard 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: Thomas N. Hibbard is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1929 births, 2016 deaths, 20th-century American mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for Thomas N. Hibbard 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.
