Key takeaways

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

Reference excerpt

Peter Johan Lor is a South African librarian and library and information science scholar specialising in international librarianship. He was the Director of the State Library in Pretoria from 1992 and served as the first National Librarian and Chief Executive Officer of the National Library of South Africa from 2000 to 2003 following the consolidation of the State Library (Pretoria) and South African Library in 1999.

He earned a D.Phil. in Library and Information Science from the University of Pretoria in 1990. As a librarian, Lor served in various libraries in South Africa as well as holding the position of senior librarian at the University of Pretoria (1976–80). Lor was director of the South African State Library for eight years.

Teaching Lor was associate professor and then a professor in Information Science at the University of South Africa (1986–1992). He has also taught at the University of Pretoria in the Department of Information Science. He held a visiting professor appointment at the University of Wisconsin-Milwaukee in the School of Information Studies from 2009–2011. From 1998 to 2016 he was an Extraordinary Professor in the Department of Information Science, University of Pretoria.

Publications Peter Lor is the author of over 150 professional and research publications. In 2019 his book, International and Comparative Librarianship: a Thematic Approach was published as part of the IFLA series, Global Studies in Library and Information. Lor's research interests include:

Developmental role of libraries in developing countries National and regional information policy Library and information services legislation Information flows between developed and developing countries International and comparative librarianship and information work National digital heritage: capturing, organization, preservation and access Research methods in library and information science Selected publications:

Worked examples

Example 1 — a first encounter with Peter Johan Lor

Start with the simplest possible case. Write down what Peter Johan Lor 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 Peter Johan Lor 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 Peter Johan Lor 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 Peter Johan Lor

In research
Peter Johan Lor 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 Peter Johan Lor 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
Peter Johan Lor is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dutch emigrants to South Africa, Historians of libraries, Library science scholars, so understanding it makes those chapters shorter.
In everyday life
Look for Peter Johan Lor 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.
