Reference excerpt

Zdzisław Józef Porosiński (19 March 1955 in Kłodzko, Poland – 19 March 2016 in Wrocław, Poland) was a Polish mathematician and statistician.

Biography In 1979, he graduated in mathematics from Faculty of Fundamental Problems of Technology, Wrocław University of Technology with a master's degree. After graduation, he started working at his alma mater at the Institute of Mathematics (later renamed Institute of Mathematics and Informatics of the Wrocław University of Technology, and from 2015 transformed into the Faculty of Pure and Applied Mathematics). On 17 March 1987, he defended his doctoral dissertation entitled Selected problems of optimal stopping . The research supervisor and thesis supervisor was professor Stanisław Trybuła. On 20 November 2003, the habilitation colloquium was held. On 31 May 2004, he obtained a postdoctoral degree in mathematical sciences. In the years 2001–2008 he worked at the Institute of Basic Sciences State Higher Vocational School in Nysa. In the years 2006–2012 he was the deputy director for didactics at Institute of Mathematics and Computer Science of the Wrocław University of Technology. From 2009 he was a professor Wrocław University of Technology.

Contributions His research contributions include over 40 papers. His work in probability theory included work on optimal stopping of the sequences of random variables and the statistics of stochastic processes. The most cited results concern the optimal strategies for the optimal stopping problem when the decision horizon is random. He was the doctoral advisor of one student.

Worked examples

Example 1 — a first encounter with Zdzisław Józef Porosiński

Start with the simplest possible case. Write down what Zdzisław Józef Porosiński claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 Zdzisław Józef Porosiński 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 Zdzisław Józef Porosiński 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 Zdzisław Józef Porosiński

In research: Zdzisław Józef Porosiński appears in mathematics 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 Zdzisław Józef Porosiński 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: Zdzisław Józef Porosiński is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, 2016 deaths, Polish mathematician stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Zdzisław Józef Porosiński 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.
