Péter Surján is a chemistry 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 Péter Surján rather than just read about it. In short: Péter R. Surján (born August 30, 1955) is a Hungarian theoretical chemist who is known for his research on application of the theory of second quantization in quantum chemistry.

Key takeaways

Péter Surján belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Péter Surján to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Péter Surján from memory before moving on to harder problems.

Reference excerpt

Péter R. Surján (born August 30, 1955) is a Hungarian theoretical chemist who is known for his research on application of the theory of second quantization in quantum chemistry. In 2016 a festschrift from Theoretical Chemistry Accounts journal was published in his name which is also published as a book in Highlights in Theoretical Chemistry series by the Springer Nature. He is currently a professor and a former dean of the Faculty of Science of the Eötvös Loránd University.

Academic career Surján received his Master's degree in physics in 1978 and his PhD in quantum chemistry in 1981, both from (Eötvös Loránd University. In 1986, he was a Candidate of Science. From there, he worked at the Technical University of Budapest as a senior researcher in physics from 1990 to 1995 before moving to Eötvös Loránd University, where he has been since. He has taught in the Department of Theoretical Chemistry since 1991, becoming a full professor in 1998, and has been the Director of the Bolyai College (2007-2012) and the Institute of Chemistry (2008-2012). He was also the dean of the Faculty of Science. Surján is a member of the Hungarian Academy of Sciences (1998) and has been on the editorial boards of the Journal of Mathematical Chemistry and Interdisciplinary Sciences: Computational Life Sciences. He has also been a guest editor for the International Journal of Quantum Chemistry. Surján has published more than 190 papers in his scientific career. His first paper was published in 1980.

Worked examples

Example 1 — a first encounter with Péter Surján

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

In research: Péter Surján appears in chemistry 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 Péter Surján 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: Péter Surján is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, Academic staff of Eötvös Loránd University, Chemist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Péter Surján 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.
