Reference excerpt

İhsan Ketin (10 April 1914 – 16 December 1995) was a Turkish earth scientist.

Early years He was born in 1914 in the Central Anatolian town of Kayseri, located at the foothills of Mt. Aergus (the volcano Erciyes). He won a state scholarship to study natural sciences abroad, as part of Mustafa Kemal Atatürk's plans of modernizing the newly formed Republic of Turkey. He started his undergraduate studies in Natural Sciences at Berlin University in 1934, and subsequently completed his doctorate at Bonn University in 1938 under the supervision of Hans Cloos, thus becoming the first native of Turkey with a doctorate degree in geology in the Republic of Turkey. Ketin returned to Turkey in 1938, and started his career as assistant professor at the Geological Institute of Istanbul Technical University.

Scientific career Through a faithful coincidence, the long-dormant North Anatolian fault awoke to activity, first gently with the Tercan quake of 21 November 1939, but then violently with the great Erzincan catastrophe of 28 and 29 December 1939, which claimed the lives of some 32.000 people. Ketin rushed to the field with many other geologists, Turkish and foreign, to map the surface breaks and the fearful damage. After Ketin published his paper on the North Anatolian fault, its importance was acknowledged when he was awarded the coveted Gustav-Steinmann-Medaille, the highest distinction the Geologische Vereinigung e.V. gives, in the journal, in which Ketin's paper had been published. In 1953, Ketin accepted a new position, the chair in General Geology in the Faculty of Mines at Istanbul Technical University. In 1953, he published his well-known comparison of the San Andreas and North Anatolian faults. Ketin contributed four major papers to the International Tectonic Map of Europe, published in 1960, in which he portrays Turkey as a dominantly asymmetric orogen, accreted from north to south. His tectonic and kinematic views formed the basis for many large-scale tectonic models in Turkey. Ketin retired from active teaching in 1983, but remained in the Department of Geology as professor emeritus until his death in 1995. Ketin had an enormous memory capability. As Celal Sengör, one of his students, said he was a hafiz able to reciting all Koran verses in Arabic and Turkish.

Worked examples

Example 1 — a first encounter with İhsan Ketin

Start with the simplest possible case. Write down what İhsan Ketin 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 İhsan Ketin 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 İhsan Ketin 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 İhsan Ketin

In research: İhsan Ketin 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 İhsan Ketin 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: İhsan Ketin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1914 births, 1995 deaths, 20th-century geologists, so understanding it makes those chapters shorter.
In everyday life: Look for İhsan Ketin 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.
