Jack Souther

Jack Souther is a earth science 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 Jack Souther rather than just read about it. In short: Jack Gordon Souther (April 25, 1924 – June 1, 2014) was an American-born Canadian geologist, volcanologist, professor and engineer. He contributed significantly to the early understanding of recent volcanic activity in the Canadian Cordillera.

Key takeaways

Jack Souther 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 Jack Souther to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Jack Souther from memory before moving on to harder problems.

Reference excerpt

Jack Gordon Souther (April 25, 1924 – June 1, 2014) was an American-born Canadian geologist, volcanologist, professor and engineer. He contributed significantly to the early understanding of recent volcanic activity in the Canadian Cordillera. Many of his publications continue to be regarded as classics in their field, even now several decades after they were written.

Biography Souther was born in Chicago, Illinois, United States on April 25, 1924. As a young child he moved to the U.S. state of Alabama. In his teenage years, Souther relocated with his family to the Canadian province of Alberta at a cattle ranch near the First Nations settlement of Morley. After his family lost the ranch, Souther moved with his family to the mountain town of Banff. Here, he attended Banff High School. In 1945 at the age of 21, Souther graduated as the class president. He was later accepted into a geological engineering program at the University of British Columbia in Vancouver. He was offered a full scholarship to Princeton University in Princeton, New Jersey, after excelling to such a degree at the University of British Columbia. Consequently, he enrolled in the Ph.D. program for geology. After completing his degree, Souther joined the Geological Survey of Canada (GSC) office in Vancouver and carved out a remarkable career as one of the country's leading authorities on geothermal resources and volcanism in the Canadian Cordillera. Souther had long been in demand as a public speaker because of his ability to communicate scientific ideas to lay audiences. This included his ability to be a principal in media interviews, a participant in radio and television open-line shows and as a main figure in television broadcasts handling with its scientific concentration. Souther received the Bancroft Award for "publication, instruction, and research in the earth sciences that have conspicuously contributed to public understanding and appreciation of the subject" from the Royal Society of Canada in 1984. After retiring to the position of emeritus scientist in 1992, Souther began his second career as a ski guide/mountain host at the Whistler Blackcomb ski resort. In 1995, he received the Career Achievement Award in volcanology and igneous petrology by the Geological Association of Canada. Jack Souther was one of the first members to join the Whistler Naturalists, a society founded in the resort town of Whistler, British Columbia, during the late 1990s. During his time with the society he discussed the geology and natural history of the Whistler area. Jack Souther died on June 1, 2014, in Lions Gate Hospital, North Vancouver at the age of 90 following a long battle with cancer. He is survived by his wife Betty and their three daughters Anne, Barbara and Janet.

Worked examples

Example 1 — a first encounter with Jack Souther

Start with the simplest possible case. Write down what Jack Souther 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 Jack Souther 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 Jack Souther 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 Jack Souther

In research: Jack Souther 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 Jack Souther 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: Jack Souther is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1924 births, 2014 deaths, 20th-century Canadian geologists, so understanding it makes those chapters shorter.
In everyday life: Look for Jack Souther 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.
