Reference excerpt

John J. McKetta Jr. (October 17, 1915 – January 15, 2019) was an American chemical engineer known for his research on more efficient ways to create energy and the thermodynamic properties of hydrocarbons.

Life Born in Wyano, Pennsylvania to Ukrainian immigrant parents, he initially worked as a coal miner. He obtained his BSE from Tri-State College (now Trine University) in Angola, Indiana, and, MS and PhD degrees from the University of Michigan. He joined the faculty of the chemical engineering department of the University of Texas in 1946, later serving as department chair, dean of the UT College of Engineering, and vice chancellor of the UT System. He served as energy advisor to Presidents Richard Nixon, Gerald Ford, Ronald Reagan, and George H. W. Bush. He published over 400 papers and wrote or edited 87 books, including the 68-volume "Encyclopedia of Chemical Processing and Design". He was elected to the National Academy of Engineering and, in 2009, was selected by the American Institute of Chemical Engineers as one of the "50 Chemical Engineers of the Foundation Age." He also served as president of AIChE in 1962. In 1997, Trine University named its department of chemical engineering in his honor and in 2016 Trine named him "Patron Saint of the Faculty" in honor of his dedication to his alma mater. In 2012, the University of Texas renamed his department as the John J. McKetta Jr. Department of Chemical Engineering. As a published author, he is widely held in libraries worldwide. He died in January 2019, aged 103.

Worked examples

Example 1 — a first encounter with John J. McKetta

Start with the simplest possible case. Write down what John J. McKetta 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 John J. McKetta 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 John J. McKetta 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 John J. McKetta

In research: John J. McKetta 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 John J. McKetta 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: John J. McKetta is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1915 births, 2019 deaths, 20th-century American science writers, so understanding it makes those chapters shorter.
In everyday life: Look for John J. McKetta 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.
