Marek Sierka

Marek Sierka is a astronomy 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 Marek Sierka rather than just read about it. In short: Marek Sierka (born 1971) is a theoretical chemist, Professor of Computational Materials Science at the Otto Schott Institute of Materials Research at the Friedrich Schiller University Jena. Biography He studied chemistry and physics at the Jagiellonian University (1991–1994), the University of Bergen (1994–1995) and the Humboldt University of Berlin (1995–1996).

Key takeaways

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

Reference excerpt

Marek Sierka (born 1971) is a theoretical chemist, Professor of Computational Materials Science at the Otto Schott Institute of Materials Research at the Friedrich Schiller University Jena.

Biography He studied chemistry and physics at the Jagiellonian University (1991–1994), the University of Bergen (1994–1995) and the Humboldt University of Berlin (1995–1996). In June 1996 he graduated with a Master of Science degree in chemistry from the Jagiellonian University. In November 2000 he obtained a doctorate in chemistry (summa cum laude) from the Humboldt University of Berlin, under the supervision of Joachim Sauer. In June 2009 he obtained habilitation in theoretical chemistry from the Humboldt University of Berlin. In October 2009 he was appointed as lecturer at the Humboldt University of Berlin. In September 2011 he was a visiting professor at the Italian Institute of Technology at the National Nanotechnology Laboratories in Lecce. In 2012 he was appointed Professor of Computational Materials Science at the Otto Schott Institute of Materials Research at the Friedrich Schiller University Jena. Between 2016 and 2017 he was a lecturer at the Jagiellonian University. His fields of interest include modeling and atomistic simulations, structure, properties and reactivity of low-dimensional systems (clusters, nanoparticles, thin layers, surfaces) as well as methods for global structural optimization and design of functional materials. Since 2017 he has been a member of the editorial board of Materials. He was elected a member of the Gesellschaft Deutscher Chemiker e.V. (GDCh) and the Arbeitsgemeinschaft für Theoretische Chemie (AGTC).

Worked examples

Example 1 — a first encounter with Marek Sierka

Start with the simplest possible case. Write down what Marek Sierka 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 Marek Sierka 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 Marek Sierka 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 Marek Sierka

In research: Marek Sierka 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 Marek Sierka 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: Marek Sierka is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1971 births, Academic staff of the University of Jena, Jagiellonian University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Marek Sierka 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.
