Reference excerpt

Veleslav Wahl (15 May 1922 – 16 June 1950) was a Czech ornithologist and resistance activist who was executed in 1950.

Biography

Veleslav Wahl was born on 15 May 1922 in Prague. He was named after his father, a Prague lawyer, who was born in 1891 and killed in 1942 by the Nazis. As a child Veleslav went to a local grammar school in Bělá pod Bezdězem. He also worked in the Prague Zoo from 1941 to 1944 while also working in the underground Czech resistance. When the war ended he studied law at Charles University. He was also active in the Prague uprising as a student activist. He established an anti-communist organization along with Jaromír Nechanský which collaborated with the Office of Strategic Services, particularly the American secretary Walter Birge who was posted to the Prague embassy. For this he was arrested in 1949 and sentenced to death after a trial. He and Nechanský were executed in Pankrác Prison on 16 June 1950. The Wahl-Nechanský trial also led to the Czechoslovak government notifying the Americans that their embassy was too large due to their espionage activities and ordered them to reduce it to a third of its size. His wife, Tatiána Růžičková, was also kept under arrest and she later moved to the United States. A memorial to Wahl and others executed and tortured from the 1950s was established at Prague-Ďáblice, and in 2000, he was posthumously awarded the Honorary Medal of T. G. Masaryk by the Masaryk Democratic Movement. In 1995 he was posthumously decorated with the Order of the White Lion (Civil Division, Second Class). In 2017, a memorial plaque was installed on the Swedish embassy where he had lived before his execution. Wahl wrote a landmark work on the birds of Prague (Pražské ptactvo), published first in 1944 with a second edition in 1945.

Worked examples

Example 1 — a first encounter with Veleslav Wahl

Start with the simplest possible case. Write down what Veleslav Wahl 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 Veleslav Wahl 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 Veleslav Wahl 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 Veleslav Wahl

In research: Veleslav Wahl 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 Veleslav Wahl 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: Veleslav Wahl is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1922 births, 1950 deaths, Czechoslovak zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Veleslav Wahl 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.
