Reference excerpt

John Michael Holzinger (1853 – 1929) was a German-born American bryologist, expert on the bryoflora of Colorado, and third president of the Sullivant Moss Society.

Biography

Holzinger was born on May 14, 1853, in Hachtel, Germany. In 1874, he graduated from Olivet College. Holzinger went on to teach science and botany at Winona State Normal School from 1882 to 1890. In 1890, he left to join the United States Department of Agriculture division of botany. In 1893, he returned to Winona where he remained until 1922. Holzinger made several noteworthy collections of bryophytes and exsiccata series from North America. His exsiccata Musci Acrocarpi Boreali-Americani was a valuable asset to 20th century bryology. The series Mosses of Colorado. Distributed by J. M. Holzinger: collected by Carl F. Baker 1896 distributed specimens collected by Charles Fuller Baker.

Legacy Triodanis holzingeri was named in Holzinger's honor by Rogers McVaugh.

Worked examples

Example 1 — a first encounter with John Michael Holzinger

Start with the simplest possible case. Write down what John Michael Holzinger 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 John Michael Holzinger 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 John Michael Holzinger 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 John Michael Holzinger

In research: John Michael Holzinger 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 John Michael Holzinger 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: John Michael Holzinger is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1853 births, 1929 deaths, American botanists, so understanding it makes those chapters shorter.
In everyday life: Look for John Michael Holzinger 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.
