Klaus Bechgaard

Klaus Bechgaard 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 Klaus Bechgaard rather than just read about it. In short: Klaus Bechgaard (5 March 1945 – 7 March 2017) was a Danish scientist and chemist, noted for being one of the first scientists in the world to synthesize a number of organic charge transfer complexes and demonstrate their superconductivity, therefore the name Bechgaard salt. These salts all exhibit superconductivity at low temperatures.

Key takeaways

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

Reference excerpt

Klaus Bechgaard (5 March 1945 – 7 March 2017) was a Danish scientist and chemist, noted for being one of the first scientists in the world to synthesize a number of organic charge transfer complexes and demonstrate their superconductivity, therefore the name Bechgaard salt. These salts all exhibit superconductivity at low temperatures. The first organic superconductor was discovered by Bechgaard and Denis Jérome in 1979. This discovery garnered attention in the international scientific community, and for a period he was one of the most cited scientists in the field of natural sciences. He also received a nomination for the Nobel Prize in chemistry for this discovery.

Research Klaus Bechgaard did research at the University of Copenhagen, where he also held a Professorship in organic chemistry until 1993. From 1993 until 2000 he was the chairman of the Department of Physics and Chemistry at Risø and in 2001 he was appointed head of the newly assigned Department of Polymer Research at Risø. From 2001 and onwards he was the head of Risø's nano technology programme, and The Danish Center of Polymers which is a joint venture between the Technical University of Copenhagen and Risø. Bechgaard also conducted research in the field of polymers and nano technology at the University of Copenhagen.

Worked examples

Example 1 — a first encounter with Klaus Bechgaard

Start with the simplest possible case. Write down what Klaus Bechgaard 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 Klaus Bechgaard 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 Klaus Bechgaard 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 Klaus Bechgaard

In research: Klaus Bechgaard 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 Klaus Bechgaard 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: Klaus Bechgaard is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1945 births, 2017 deaths, Academic staff of the University of Copenhagen, so understanding it makes those chapters shorter.
In everyday life: Look for Klaus Bechgaard 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.
