Ken Freeman (astronomer)

Ken Freeman (astronomer) 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 Ken Freeman (astronomer) rather than just read about it. In short: Kenneth Charles Freeman (born 27 August 1940) is an Australian astronomer and astrophysicist who is currently Duffield Professor of Astronomy in the Research School of Astronomy and Astrophysics at the Mount Stromlo Observatory of the Australian National University in Canberra. He was born in Perth, Western Australia in 1940, studied mathematics and physics at the University of Western Australia, and graduated with…

Key takeaways

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

Reference excerpt

Kenneth Charles Freeman (born 27 August 1940) is an Australian astronomer and astrophysicist who is currently Duffield Professor of Astronomy in the Research School of Astronomy and Astrophysics at the Mount Stromlo Observatory of the Australian National University in Canberra. He was born in Perth, Western Australia in 1940, studied mathematics and physics at the University of Western Australia, and graduated with first class honours in applied mathematics in 1962. He then went to Cambridge University for postgraduate work in theoretical astrophysics with Leon Mestel and Donald Lynden-Bell, and completed his doctorate in 1965. Following a postdoctoral appointment at the University of Texas with Gérard de Vaucouleurs, and a research fellowship at Trinity College, Cambridge, he returned to Australia in 1967 as a Queen Elizabeth Fellow at Mount Stromlo. Apart from a year in the Kapteyn Institute in Groningen in 1976 and some occasional absences overseas, he has been at Mount Stromlo ever since. His research interests are in the formation and dynamics of galaxies and globular clusters, and he is particularly interested in the problem of dark matter in galaxies: he was one of the first to point out that spiral galaxies contain a large fraction of dark matter. He regularly visits the Space Telescope Science Institute as distinguished visiting scientist. He is very active in supporting graduate students and has acted as primary supervisor for 13 postdocs and 62 PhD students, most recently Stephanie Monty on globular cluster populations in the Milky Way. Five of his students have won Hubble Fellowships. He is active in international astronomy, as a division past-president of the International Astronomical Union, and serves on visiting committees for several major astronomical institutions around the world. He has been an invited speaker at 167 international conferences since 1969. He has co-authored a book on dark matter.

Worked examples

Example 1 — a first encounter with Ken Freeman (astronomer)

Start with the simplest possible case. Write down what Ken Freeman (astronomer) 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 Ken Freeman (astronomer) 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 Ken Freeman (astronomer) 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 Ken Freeman (astronomer)

In research
Ken Freeman (astronomer) 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 Ken Freeman (astronomer) 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
Ken Freeman (astronomer) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, 20th-century Australian astronomers, 21st-century Australian astronomers, so understanding it makes those chapters shorter.
In everyday life
Look for Ken Freeman (astronomer) 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.
