Richard E. Pattis

Richard E. Pattis 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 Richard E. Pattis rather than just read about it. In short: Richard Eric Pattis is an American professor emeritus at the University of California, Irvine's Donald Bren School of Information and Computer Sciences, where he taught introductory programming and data structures. He is the author of the Karel programming language, and published Karel the Robot: A gentle introduction to the art of programming.

Key takeaways

Richard E. Pattis 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 Richard E. Pattis to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Richard E. Pattis from memory before moving on to harder problems.

Reference excerpt

Richard Eric Pattis is an American professor emeritus at the University of California, Irvine's Donald Bren School of Information and Computer Sciences, where he taught introductory programming and data structures. He is the author of the Karel programming language, and published Karel the Robot: A gentle introduction to the art of programming. Pattis has been a professor of computer science at Carnegie Mellon University and the University of Washington. He holds a master's degree from Stanford University. He has moved back to Pittsburgh where he is a special faculty member at Carnegie Mellon University, advising CS undergraduates. In 2011, he was elected an ACM Distinguished Member.

Worked examples

Example 1 — a first encounter with Richard E. Pattis

Start with the simplest possible case. Write down what Richard E. Pattis 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 Richard E. Pattis 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 Richard E. Pattis 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 Richard E. Pattis

In research: Richard E. Pattis 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 Richard E. Pattis 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: Richard E. Pattis is common in secondary-school and first-year university syllabi. It links to neighbouring topics American academic scientist stubs, American computer science educators, Computer scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Richard E. Pattis 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.
