Reference excerpt

Johann Georg Hoyer (23/26 August 1663, Mühlhausen – 1 April 1738) was a city physician in the town of Mühlhausen and natural philosopher. He was a member of the Leopoldina Academy of Scholars.

Life and work

Hoyer was born in a well-known Mühlhausen family and went to grammar school in Weissenfels. From 1684 he studied medicine at the University of Jena and then became a general practitioner in Mühlhausen. He visited England, Holland and Denmark in 1689 and spent four years in Copenhagen. He returned in 1693 in which time his parents' home had been destroyed in a fire. He received a doctorate from the University of Halle with a thesis that supported and translated the ideas of Friedrich Hoffmann (1660–1742) who refuted the ideas of Cornelis Bontekoe (1647–1685) and Steven Blankaart (1650–1702) that diseases arose from interactions between acid and mucus. He was made city physician by the council of Mühlhausen. In 1695 he was admitted as a member (registration number 216) of the German Academy of Natural Scientists Leopoldina under the pseudonym Apollodorus I. His most famous work was a medical guide published in 1716 which was a revised edition of Pharmacopoea domestica er postalis (1668) by Laurentius Blumentrost (1619–1705) which went by the title of Hauß- und Reiß-Apotheck - a manual of home and travel remedies for various diseases. This included various doubtful ideas including the recipe for a curative rosemary water that was supposedly written by the Queen Elizabeth of Hungary. In the preface Hoyer wrote that Blumentrost was driven not by honor and money to serve in Russia but was answering a divine call to duty. Hoyer had two sons, physician Christoph Eugen Hoyer and lawyer Georg Leopold Hoyer. A memorial is in the Marienkirche in Mühlhausen.

Worked examples

Example 1 — a first encounter with Johann Georg Hoyer

Start with the simplest possible case. Write down what Johann Georg Hoyer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Johann Georg Hoyer 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 Johann Georg Hoyer 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 Johann Georg Hoyer

In research: Johann Georg Hoyer appears in 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 Johann Georg Hoyer 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: Johann Georg Hoyer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1663 births, 1738 deaths, 18th-century German medical doctors, so understanding it makes those chapters shorter.
In everyday life: Look for Johann Georg Hoyer 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.
