Gunnar Johannsen

Gunnar Johannsen 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 Gunnar Johannsen rather than just read about it. In short: Gunnar Johannsen (born 1940) is a German cyberneticist, and Emeritus Professor of Systems Engineering and Human-Machine Systems at the University of Kassel, known for his contributions in the field of human-machine systems. Biography Born and raised in Hamburg, Johannsen received his Dipl.-Ing. in communication and information engineering from Technische Universität Berlin in 1967, where in 1971 he also received his…

Key takeaways

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

Reference excerpt

Gunnar Johannsen (born 1940) is a German cyberneticist, and Emeritus Professor of Systems Engineering and Human-Machine Systems at the University of Kassel, known for his contributions in the field of human-machine systems.

Biography Born and raised in Hamburg, Johannsen received his Dipl.-Ing. in communication and information engineering from Technische Universität Berlin in 1967, where in 1971 he also received his Dr.-Ing. in flight guidance and manual control. He studied Sound Engineering at the Berlin University of the Arts for another three years, and received his habilitation in 1980. In 1971 Johannsen started his academic career as division head at the Research Institute for Human Engineering (FGAN-FAT) in Wachtberg, south of Bonn. After his habilitation in 1980 he became privatdozent in the field of human-machine systems at the Department of Mechanical Engineering at RWTH Aachen University. In 1982 he moved to the University of Kassel, where he was appointed Professor of Systems Engineering and Human-Machine Systems until his retirement in 2006. Over the years, Johannsen was a visiting Scholar at the University of Illinois at Urbana-Champaign in 1977−78, at the Kyoto Institute of Technology in 1995 and 2004; at the Vienna University of Technology in 1999; and at the University of British Columbia in 2004. Johannsen was a fellow of the International Federation of Automatic Control, where in 1981 he founded the Working Group on Man-Machine Systems, and served in different positions over the years. In 1995, he was awarded the Japanese-German Research Award by the Japan Society for the Promotion of Science. In 2001 he was elected Fellow of the IEEE. In 2005 the University of Valenciennes and Hainaut-Cambresis awarded him a Docteur Honoris Causa, and in 2007 the Benjamin Franklin Institute of Technology nominated him for the 2007 Bower Award and Prize for Achievement in Science on Human-Centered Computing.

Work

Graphical intelligent dialogues In 1986, Jim Alty's HCI group at The Turing Institute won a major European Strategic Program on Research in Information Technology 1 contract to investigate the use of Knowledge Based systems in Process Control Interfaces called GRADIENT (Graphical Intelligent Dialogues, P600). with Gunnar Johannsen of Kassel University, Peter Elzer of the Clausthal University of Technology and Asea Brown Boveri to create intelligent interfaces for process control operators. This work had a major impact on process control interface design. The initial pilot phase report (Alty, Elzer et al., 1985) was widely used and cited. Many research papers were produced A follow-on large ESPRIT research project was PROMISE (Process Operators Multimedia Intelligent Support Environment) working with DOW Benelux (Netherlands), Tecsiel (Italy) and Scottish Power (Scotland).

Worked examples

Example 1 — a first encounter with Gunnar Johannsen

Start with the simplest possible case. Write down what Gunnar Johannsen 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 Gunnar Johannsen 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 Gunnar Johannsen 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 Gunnar Johannsen

In research
Gunnar Johannsen 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 Gunnar Johannsen 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
Gunnar Johannsen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, Academic staff of the University of Kassel, Berlin University of the Arts alumni, so understanding it makes those chapters shorter.
In everyday life
Look for Gunnar Johannsen 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.
