Jan Perner

Jan Perner is a engineering 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 Jan Perner rather than just read about it. In short: Jan Perner (7 September 1815 – 10 September 1845) was a Czech railway engineer. Between 1842 and 1845, Perner was responsible for construction of several railways in the Austrian Empire.

Reference excerpt

Jan Perner (7 September 1815 – 10 September 1845) was a Czech railway engineer. Between 1842 and 1845, Perner was responsible for construction of several railways in the Austrian Empire.

Career Perner was born on 7 September 1815 in Bratčice. He was born to a watermill owner and his wife. During 1830–33 he studied at an engineering school in Prague led by František Josef Gerstner. When Gerstner looked for engineers for construction of railways in Sankt Petersburg area of Imperial Russia, Perner joined the project (1836). Due to problems in communication with Gerstner he left in the same year. In 1837 Perner began work at the state railway company and was gradually promoted to take responsibility for construction works. In 1842 he started to design and oversee construction of important railways between Prague–Pardubice–Olomouc and Prague–Dresden.

The railway from Prague to Pardubice (over 100 km) was finished in 1845. On 9 September 1845, while Perner was returning from an inspection trip he looked out of the window of a moving train (near Choceň). His head hit a pole, and he was severely injured and died the next day in Pardubice. He has the dubious fame of being the first person to die in a railway accident in Bohemia. Today one of the faculties of University of Pardubice is named after him: Jan Perner Transport Faculty (Dopravní fakulta Jana Pernera) [1]. An InterCity class train of railway operator České dráhy bears the name Jan Perner.

Worked examples

Example 1 — a first encounter with Jan Perner

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

In research: Jan Perner appears in engineering 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 Jan Perner 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: Jan Perner is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1815 births, 1845 deaths, 19th-century Czech people, so understanding it makes those chapters shorter.
In everyday life: Look for Jan Perner 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.

Frequently asked questions

What is Jan Perner in simple terms?

Jan Perner (7 September 1815 – 10 September 1845) was a Czech railway engineer. Between 1842 and 1845, Perner was responsible for construction of several railways in the Austrian Empire.

Why does Jan Perner matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Jan Perner?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
