Richard Taaffe

Richard Taaffe 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 Richard Taaffe rather than just read about it. In short: Edward Charles Richard (Graf von) Taaffe (1898–1967), known as Richard, was an Irish gemmologist who found the first cut and polished taaffeite in November 1945. Biography Taaffe was born and grew up on the Bohemian estate of Ellischau (today Nalžovské Hory), the family seat.

Reference excerpt

Edward Charles Richard (Graf von) Taaffe (1898–1967), known as Richard, was an Irish gemmologist who found the first cut and polished taaffeite in November 1945.

Biography Taaffe was born and grew up on the Bohemian estate of Ellischau (today Nalžovské Hory), the family seat. For a short time, the composer Ralph Benatzky was his tutor. He was the son of Count Henry Taaffe, 12th Viscount Taaffe, an Austrian landowner, and Maria Magda Fuchs; his grandfather was the Austrian Prime Minister Eduard Taaffe. His father had once held hereditary titles from two different countries: he was a Count (Graf) of the Holy Roman Empire and a viscount in the Peerage of Ireland. Richard Taaffe, however, inherited neither the viscountcy, which was suspended by the Titles Deprivation Act 1917, as his father had served on the Austrian side in World War I, nor the title of Count, as Austria had generally abolished titles of nobility in 1919. Taaffe was nonetheless almost always referred to in English-speaking countries as count. In the years after World War I, Richard Taaffe emigrated to the Irish Free State and worked there as a gemologist. In October 1945, he discovered the very rare mineral taaffeite (Mg 3 Al 8 BeO 16, also known as magnesiotaaffeite, 2N'2S ), which was later named after him: Taaffe had a large number of old cut gems obtained from the Dublin jeweller Robert Dobbie, extracted from old jewellery. Upon close examination, Taaffe found that a spinel-derived purple stone originating from Sri Lanka had a birefringence that was absent in a spinel. Unable to explain this phenomenon, Taaffe sent the stone to B. W. Anderson in the London Chamber of Commerce's laboratory. After extensive analysis, it was finally recognized that the stone was an unidentified mineral, which was confirmed in 1949 by the discovery of a second specimen. With Richard Taaffe's death in 1967, no heirs to either title remained and both the Austrian and the Irish titles became extinct.

Worked examples

Example 1 — a first encounter with Richard Taaffe

Start with the simplest possible case. Write down what Richard Taaffe 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 Richard Taaffe 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 Richard Taaffe 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 Richard Taaffe

In research: Richard Taaffe 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 Richard Taaffe 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: Richard Taaffe is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1898 births, 1967 deaths, Austrian emigrants to Ireland, so understanding it makes those chapters shorter.
In everyday life: Look for Richard Taaffe 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.
