Jörg-Rüdiger Sack

Jörg-Rüdiger Sack is a computer science 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 Jörg-Rüdiger Sack rather than just read about it. In short: Jörg-Rüdiger Wolfgang Sack (born in Duisburg, Germany) is a professor of computer science at Carleton University, where he holds the SUN–NSERC chair in Applied Parallel Computing. Sack received a master's degree from the University of Bonn in 1979 and a Ph.D. in 1984 from McGill University, under the supervision of Godfried Toussaint.

Key takeaways

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

Reference excerpt

Jörg-Rüdiger Wolfgang Sack (born in Duisburg, Germany) is a professor of computer science at Carleton University, where he holds the SUN–NSERC chair in Applied Parallel Computing. Sack received a master's degree from the University of Bonn in 1979 and a Ph.D. in 1984 from McGill University, under the supervision of Godfried Toussaint. He is co-editor-in-chief of the journal Computational Geometry: Theory and Applications, co-editor of the Handbook of Computational Geometry (Elsevier, 2000, ISBN 978-0-444-82537-7), and co-editor of the proceedings of the biennial Algorithms and Data Structures Symposium (WADS). He was a co-founding editor-in-chief of the open access Journal of Spatial Information Science but is no longer an editor there. Sack's research interests include computational geometry, parallel algorithms, and geographic information systems.

Worked examples

Example 1 — a first encounter with Jörg-Rüdiger Sack

Start with the simplest possible case. Write down what Jörg-Rüdiger Sack claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, 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 Jörg-Rüdiger Sack 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 Jörg-Rüdiger Sack 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 Jörg-Rüdiger Sack

In research: Jörg-Rüdiger Sack appears in computer science 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 Jörg-Rüdiger Sack 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: Jörg-Rüdiger Sack is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of Carleton University, Canadian computer scientists, Canadian computer specialist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Jörg-Rüdiger Sack 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.
