Gustav Heinrich Tammann

Gustav Heinrich Tammann is a astronomy 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 Gustav Heinrich Tammann rather than just read about it. In short: Gustav Heinrich Johann Apollon Tammann (9 June [O.S. 28 May] 1861 – 17 December 1938) was a prominent Baltic German chemist-physicist who made important contributions in the fields of glassy and solid solutions, heterogeneous equilibria, crystallization, and metallurgy. He first predicted the order-disorder transition in alloys.

Key takeaways

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

Reference excerpt

Gustav Heinrich Johann Apollon Tammann (9 June [O.S. 28 May] 1861 – 17 December 1938) was a prominent Baltic German chemist-physicist who made important contributions in the fields of glassy and solid solutions, heterogeneous equilibria, crystallization, and metallurgy. He first predicted the order-disorder transition in alloys.

Biography Tammann was born in Yamburg (now Kingisepp, Leningrad Oblast). His father, Heinrich Tammann (1833–1864) was of Estonian peasant origin and his mother, Matilda Schünmann, was of German origin. Tammann graduated from University of Dorpat in chemistry. He went to Göttingen University in 1903 where he established the first Institute of Inorganic Chemistry in Germany. In 1908 he was appointed director of the Physico-Chemical Institute. Tammann died in Göttingen at age 77.

Research In 1900, he discovered the phases of ice, now known as ice II and ice III. Later, his interests focused on the physics and physical chemistry of metals and alloys (metallurgy). He was also known for the Vogel–Fulcher–Tammann equation, and the Tait–Tammann equation of state which seeks to account for the compressibility of liquids. in 1919, Tammann predicted the order-disorder transition that is found in alloys at low temperatures. Tamman and Otto Heusler also observed an anomaly in the specific heat of a bronze alloy in 1926, related to the critical points of the disorder-order transition. This transition was demonstrated in 1929 by C. H. Johannsen and J. O Linde using x-ray diffraction.

Honours and awards In 1925, Tammann was awarded Liebig Medal. On 28 May 1936, Tammann was awarded the Eagle Shield of the German Empire (Adlerschild des Deutschen Reiches), with dedication "The Doyen of German Metallurgy".

Awards Tammann was awarded the following prizes:

Liebig Medal of the Association of German Chemists (Verein Deutscher Chemiker) in 1925 Heyn Medal of the German Society for Materials Science (Deutsche Gesellschaft für Materialkunde) in 1929 Eagle Shield of the German Empire in 1936 The Tammann Commemorative Medal of the Deutsche Gesellschaft für Materialkunde is named after him.

Worked examples

Example 1 — a first encounter with Gustav Heinrich Tammann

Start with the simplest possible case. Write down what Gustav Heinrich Tammann 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 Gustav Heinrich Tammann 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 Gustav Heinrich Tammann 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 Gustav Heinrich Tammann

In research: Gustav Heinrich Tammann 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 Gustav Heinrich Tammann 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: Gustav Heinrich Tammann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1861 births, 1938 deaths, Academic staff of the University of Göttingen, so understanding it makes those chapters shorter.
In everyday life: Look for Gustav Heinrich Tammann 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.
