Key takeaways

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

Reference excerpt

Roy P. Mackal (August 1, 1925 – September 13, 2013) was a University of Chicago biologist best known to the general public for his interest in cryptozoology.

Academic background Born in Milwaukee, Wisconsin, in 1925, Mackal served in the United States Marine Corps during World War II before attending the University of Chicago, where he received his B.S. in 1949 in biology and his Ph.D. in zoology under the direction of Lloyd Kozloff. in 1953. He spent the rest of his academic career with Chicago as an educator and researcher. Much of his early research with the university was in biochemistry and virology, and during the 1950s, 1960s, and 1970s, he contributed to the university's influential "virus project", studying bacteriophages and the lysogenic cycle. He later served as a professor of zoology. Mackal was a member of the American Society for Biochemistry and Molecular Biology.

Cryptozoology Mackal is widely considered to be one of the seminal figures in the subculture of cryptozoology. According to writer Daniel Loxton and paleontologist Donald Prothero, "Cryptozoologists have often promoted 'Professor Roy Mackal, PhD.' as one of their leading figures and one of the few with a legitimate doctorate in biology. What is rarely mentioned, however, is that he had no training that would qualify him to undertake competent research on exotic animals. This raises the specter of 'credential mongering', by which an individual or organization feints a person's graduate degree as proof of expertise, even though his or her training is not specifically relevant to the field under consideration." Along with ecologist Richard Greenwell and Belgian zoologist Bernard Heuvelmans, he was one of the founding members of the International Society for Cryptozoology, which was created in 1982 at the National Museum of Natural History in Washington, D.C., with the hopes of bringing a degree of respectability to what is often seen as a pseudoscience. The organization published a quarterly newsletter and an annual journal, and members met annually at meetings held at universities throughout the world. Mackal was the ISC’s vice-president for the entirety of its existence, although the organization gradually folded in the early 21st century owing to lack of funding and the deaths of Heuvelmans and Greenwell. Mackal's 1980 book Searching for Hidden Animals was negatively reviewed in the BioScience journal as a "reflection of mankind's anxiety in the modern world of science and an obvious extension of current interest in the paranormal."

Loch Ness monster Mackal began investigation into the Loch Ness Monster phenomenon during the 1960s. In 1965, he went to the Scottish Highlands and met several members of the Loch Ness Phenomena Investigation Bureau, who were monitoring the loch in observation vans in hopes of seeing the creature. Fascinated by their work, Mackal began monitoring the waters himself and, after raising $5,000 in America for the Bureau, became the chief scientist for the project, a position he held until 1972, when the Bureau disbanded. During this time, the LNIB conducted sonar probes of the waters near Urquhart Bay and installed underwater strobe cameras with the hopes of providing evidence of the Loch Ness Monster. Mackal also designed a "biopsy harpoon", a dart-like contraption he attached to a submarine in order to collect tissue samples. The team never had an opportunity to use the biopsy harpoons, and were unable to provide any conclusive evidence that the Loch Ness Monster existed. However, Mackal himself was convinced that something lived beneath the waters after recording his own sighting of the creature in 1970, and in his 1976 book The Monsters of Loch Ness, he suggested that a population of large, previously unknown amphibians were living in the loch. Mackal later changed his mind and proposed that the creatures were zeuglodons, serpentine whales believed to have gone extinct several million years ago.

Mokele-mbembe During the 1980s, Mackal turned his attention to purported creature, the Mokele-mbembe, which figures such as Young Earth creationists claim is a living dinosaur in the Likouala swamp region of the Republic of Congo. Accompanied by University of Arizona ecologist Richard Greenwell and Congolese biologist Marcellin Agnagna, Mackal undertook two expeditions, the first in 1980 and the second in 1981, to find and photograph the creature. Mackal himself did not actually see the creature, but he and his colleagues did collect multiple firsthand reports from Congo natives, who, according to Mackal, consistently described a creature similar to a long-necked sauropod. During his interviews with the natives, Mackal also heard anecdotes about the Emela-ntouka, another possible living dinosaur which supposedly resembles a Monoclonius or Centrosaurus, the Mbielu-Mbielu-Mbielu, which is said to resemble a Kentrosaurus, and the snake- or lizard-like Nguma-monene. In 1987, Mackal wrote a book about his adventures in the Likouala swamps called A Living Dinosaur? In Search of Mokele-Mbembe. He had tried to obtain funds for a third expedition to the region, but his plans were never realized. Mackal has said of his interest in the Mokele-mbembe, “I admit that my own views are tinged with some romanticism, but certainly not to the extent that I would endure extreme hardship, even risk my life, to pursue a dream with no basis in reality.”[1]

Death Mackal died at the age of 88 in Chicago, Illinois, on September 14, 2013, of heart failure.

Worked examples

Example 1 — a first encounter with Roy Mackal

Start with the simplest possible case. Write down what Roy Mackal 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 Roy Mackal 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 Roy Mackal 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 Roy Mackal

In research
Roy Mackal 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 Roy Mackal 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
Roy Mackal is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1925 births, 2013 deaths, American biochemists, so understanding it makes those chapters shorter.
In everyday life
Look for Roy Mackal 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.
