Reference excerpt

Kim Soo-jin (Korean: 김수진; January 15, 1939 – January 10, 2025) was a South Korean mineralogist and academic, who was the discoverer of Janggunite.

Biography Kim was born on January 15, 1939. He studied geology, receiving a bachelor of science in 1961, and a master's and a doctorate by 1971 from Seoul National University. He then studied mineralogy as a Humboldt Research Fellow at the Ruprecht Karl University of Heidelberg in 1972, achieving a doctorate in mineralogy in 1974. In 1968, Kim Soo-jin became the first full-time professor of mineralogy of Seoul National University's Department of Geology. In 1975, Kim discovered a new mineral, Janggunite. In 1986, he became the first president of the Mineralogical Society of Korea, and served two more terms as its second and third president until 1992. On July 8, 1994, he became the youngest elected member of the National Academy of Sciences of the Republic of Korea. He was made professor emeritus in 2004. Kim Soo-jin died on January 10, 2025, at the age of 85.

Worked examples

Example 1 — a first encounter with Kim Soo-jin (mineralogist)

Start with the simplest possible case. Write down what Kim Soo-jin (mineralogist) 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 Kim Soo-jin (mineralogist) 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 Kim Soo-jin (mineralogist) 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 Kim Soo-jin (mineralogist)

In research: Kim Soo-jin (mineralogist) 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 Kim Soo-jin (mineralogist) 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: Kim Soo-jin (mineralogist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1939 births, 2025 deaths, Academic staff of Seoul National University, so understanding it makes those chapters shorter.
In everyday life: Look for Kim Soo-jin (mineralogist) 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.
