Ursula van Rienen

Ursula van Rienen is a mathematics 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 Ursula van Rienen rather than just read about it. In short: Ursula van Rienen (born 1957) is a German applied mathematician and physicist whose research involves computational electrodynamics, the computational simulation of interactions between electromagnetic fields and biological tissue, and its applications in electrical brain stimulation. She is a university professor in the Institut für Allgemeine Elektrotechnik at the University of Rostock, where she holds the Chair o…

Key takeaways

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

Reference excerpt

Ursula van Rienen (born 1957) is a German applied mathematician and physicist whose research involves computational electrodynamics, the computational simulation of interactions between electromagnetic fields and biological tissue, and its applications in electrical brain stimulation. She is a university professor in the Institut für Allgemeine Elektrotechnik at the University of Rostock, where she holds the Chair of Electromagnetic Field Theory.

Education and career Van Rienen studied mathematics and physics at the University of Bonn, earning a vordiplom (the equivalent of a bachelor's degree) in 1979, and a diploma (the equivalent of a master's degree) in 1983, with a minor in operations research. She worked as a researcher at DESY, the German Electron Synchrotron research center, from 1983 to 1989. In 1989 she defended a doctoral thesis through the Technische Universität Darmstadt, titled Zur numerischen Berechnung zeitharmonischer elektromagntischer Felder in offenen, zylindersymetrischen Strukturen unter Verwendung von Mehrgitterverfahren [On the numerical calculation of time-harmonic electromagnetic fields in open, cylindrically symmetrical structures using multi-grid methods], supervised by Willi Törnig. Beginning in 1990, she worked as a research assistant at the Technische Universität Darmstadt, and then a lecturer in 1995. In 1997 she completed a habilitation there, and in the same year took her current position as a professor at the University of Rostock. At Rostock, she has been dean of the Faculty of Information Technology and Electrical Engineering from 2004 to 2006, and vice rector for research and research training from 2009 to 2013.

Books Van Rienen published her habilitation thesis as the book Numerical Methods in Computational Electrodynamics: Linear Systems in Practical Applications (Springer, 2001).

Worked examples

Example 1 — a first encounter with Ursula van Rienen

Start with the simplest possible case. Write down what Ursula van Rienen 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 Ursula van Rienen 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 Ursula van Rienen 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 Ursula van Rienen

In research
Ursula van Rienen 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 Ursula van Rienen 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
Ursula van Rienen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1957 births, Academic staff of the University of Rostock, German applied mathematicians, so understanding it makes those chapters shorter.
In everyday life
Look for Ursula van Rienen 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.
