Hans A. Bachor

Hans A. Bachor is a physics 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 Hans A. Bachor rather than just read about it. In short: Hans-Albert Bachor (born December 1952) is a German-born Australian research physicist. He was chairperson of the National Youth Science Forum in Australia, and is an emeritus professor in the Department of Quantum Science, Research School of Physics at the Australian National University, Canberra, Australia.

Key takeaways

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

Reference excerpt

Hans-Albert Bachor (born December 1952) is a German-born Australian research physicist. He was chairperson of the National Youth Science Forum in Australia, and is an emeritus professor in the Department of Quantum Science, Research School of Physics at the Australian National University, Canberra, Australia.

Biography Bachor was born in Wolfenbüttel, Germany in 1952. He studied physics in Hannover, Germany, where he received his diploma and doctorate, supervised by Prof. Dr. Manfred Kock. He took up a position at the Australian National University in 1981.

Research Bachor established experimental quantum optics in Australia and created a widely known group for optics and laser physics, exploring the possibilities of harnessing the quantum nature of light. He has pioneered techniques for sensitive measurements beyond the quantum noise limit, for the improvement of optical sensors, interferometers, optical communication and data storage. Bachor has mentored and graduated a number of Australia's leading scientists. His former graduate students include Professor Ping Koy Lam (CQC2T), Professor Timothy Ralph (UQ), and Professor Andrew White (UQ). Bachor was head of the Department of Physics at the Australian National University in the late 1990s, and took a leading role in teaching and inspiring undergraduate students.

Professional activities He is active in the professional management of science, a former member of the expert panels of the Australian Research Council (1997–2001, 2010–2012) and the European Research Council (2009–2013), through leading roles in the Australian Optical Society, as chair and organiser of several international science conferences, and as a member of the advisory boards of international research Centres. His awards include the Humboldt Research Prize (1999), Fellow of the Institute of Physics (UK), the Australian Institute of Physics (AIP) and the Optical Society of America (OSA). He is recipient of the AIP Walter Boas Medal (2000), the AIP award for contributions to Physics (2009), the IOP/AIP Harrie Massey Medal (2010) and the AOS Beattie Steel medal (2010). He was awarded Membership in the Order of Australia (AM) on Australia Day 2012, recognising his achievements as research scientist and educator. He has written the widely used and cited textbook " A guide to experiments in quantum Optics", with Prof. Timothy Ralph. Bachor lives with his wife Connie Bachor in Wamboin, NSW.

Worked examples

Example 1 — a first encounter with Hans A. Bachor

Start with the simplest possible case. Write down what Hans A. Bachor claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Hans A. Bachor 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 Hans A. Bachor 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 Hans A. Bachor

In research
Hans A. Bachor appears in physics 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 Hans A. Bachor 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
Hans A. Bachor is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1952 births, Fellows of Optica (society), Fellows of the Australian Institute of Physics, so understanding it makes those chapters shorter.
In everyday life
Look for Hans A. Bachor 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.
