Key takeaways

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

Reference excerpt

John C. Holden (born 1934), often called Jack Holden, is an American geologist, scientific illustrator, and humorist known for his early research into tectonic drift with Robert S. Dietz in the 1960s and 1970s. In 1976 he founded the "International Society to Stop Continental Drift", a tongue-in-cheek organization which attracted hundreds of members and had the motto, "Eschew Sea-Floor Spreading".

Early life Holden was born in 1934 in Colón, Panama, and was raised in San Diego by his mother and her husband Warren Holden, a Navy officer. Holden's biological father was a San Diego milkman named Bud. As a child in the 1940s, Holden explored the canyons of California for days at a time and hunted rabbits with a pellet gun. When he played blackjack and acey-deucey with friends, he was known to bring a paper with the pre-calculated winning odds. Holden disliked schoolwork and preferred to draw cartoons in his notebook. Due to his learning difficulties, he was enrolled in specialized program from the San Diego State University's teacher college. In sixth grade, he developed an art style called "psychodoodles" during class. Holden eventually graduated from high school at age 21, and was accepted into San Diego State University, where he studied geology, earning a master's degree in 1961.

Geology research career

In 1961, Holden was hired by the Naval Electronics Laboratory geologist Robert S. Dietz, a prominent researcher in the new and controversial fields of plate tectonics and impact craters. For more than 10 years, Holden served as Dietz' illustrator and collaborator, adding creative elements and scientific diagrams in many of Dietz' journal articles, for which Holden was named co-author. Dietz and Holden were early "drifters", advocates for the theory that Earth was covered by slowly drifting tectonic plates. They theorized that the Moon's surface was static, and that its craters were 3 billion-year-old remnants of astroid collisions. The decade-long collaboration between Dietz and Holden involved stints in Washington, D.C. and Miami. During this period, Holden studied in a paleontology PhD program at the University of California, Berkeley but failed to graduate despite finishing his dissertation because he could not meet the requirement to read technical German. In 1973, Holden lost his job with Dietz due to budget cuts.

Independent endeavors and publications Holden later said that in the 1970s, "I more or less reconciled myself to being a dropout" and "decided to try to make it on my own." He continued to publish his illustrations and science writing, and began selling products including his "psychodoodle" drawings and custom globes with moveable continents that he had developed for Dietz. He founded (and later sold) Softwear Unlimited, which sold graphic tees with science jokes, such as an illustration of Einstein as a traffic police enforcing the speed of light: "186,000 miles per second is not only a good idea. It’s the law." In 1973, he began working with William R. Corliss to compile the multivolume "Catalog of Anomalies", which contained unusual or unexplained results from old scientific publications. The books were praised by the journal Science, and the science fiction author Arthur C. Clarke was a fan of them. Holden collaborated with Dietz again on their self-published 1987 book, Creation/Evolution Satiricon: Creationism Bashed, a takedown of religion. He has illustrated work by Peter Vogt, poetry books by the oceanographer Harris B. Stewart Jr.

Humor

Journal of Irreproducible Results Holden contributed humor writing to the Journal of Irreproducible Results. Editor Norman Sperling later called Holden the publication's "most memorable" writer.

International Stop Continental Drift Society In 1976, Holden founded a satirical club called the "International Stop Continental Drift Society" which aimed to put an end to seafloor spreading, volcanic activity, and earthquakes greater than 4.0 on the Richter scale. He jokingly told Newsweek that "something had to be done" because China and California would converge and cause "Communists to marry our children". He promoted a tongue-in-cheek counter-theory called "continental drip", based on the observation that continents appear to drip down toward the South Pole. Members paid $5 annual dues for a society newsletter published sporadically, "like natural disasters", that featured humor, research, and cartoons (such as a drawing of a whooshing continent rapidly approaching, captioned "Look Out! Here Comes Africa"). Society headquarters was the house in Winthrop where Holden lived with his elderly mother, and it was included in the Encyclopedia of Associations. Bumper stickers for the group had the slogan "Stop Continental Drift", as well as "Reunite Gondwanaland" and "Join the Mothers’ March Against Volcanos". Arthur A. Meyerhoff, prominent tectonic theory researcher, displayed the sticker on his car. By the mid-1980s, the Society had grown to 700 members, including both supporters of tectonic theory and a sect of opponents, which Holden estimated at 10% to 20% of the group. Members from the geology department of Leiden University held a humorous event on campus to "bolt down" the Eurasian plate. For the 40th anniversary of the prank in 2018, the university brought Holden and his wife to campus, where Holden presented an unconventional pet theory that continental drift was not caused by heat currents but by the spin of Earth.

Other humorous endeavors Holden also founded the "Manzana Institute of Geotechnic Redundancies" and the "Friends of the Okanogan Lobe" (FOOLs), a group of retirees that makes local expeditions to study glacial geology.

Worked examples

Example 1 — a first encounter with John C. Holden

Start with the simplest possible case. Write down what John C. Holden claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 John C. Holden 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 C. Holden 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 C. Holden

In research
John C. Holden appears in earth 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 John C. Holden 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 C. Holden is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1934 births, 20th-century American geologists, 20th-century American physicists, so understanding it makes those chapters shorter.
In everyday life
Look for John C. Holden 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.
