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

Reference excerpt

Justin R. Rattner is a retired Intel Senior Fellow, Corporate Vice President and former director of Intel Labs. Previously, he served as the corporation's Chief Technology Officer, where he was responsible for leading Intel's microprocessor, communications and systems technology labs and Intel Research. In 1989, Rattner was named Scientist of the Year by R&D Magazine for his leadership in parallel and distributed computer architecture. In December 1996, Rattner was featured as Person of the Week by ABC World News for his visionary work on the Department of Energy ASCI Red System, the first computer to sustain one trillion operations per second (one teraFLOPS) and the fastest computer in the world between 1996 and 2000. In 1997, Rattner was honored as one of the Computing 200, the 200 individuals having the greatest impact on the U.S. computer industry today, and subsequently profiled in the book Wizards and Their Wonders from ACM Press. Rattner has received two Intel Achievement Awards for his work in high performance computing and advanced cluster communication architecture. He was a longstanding member of Intel's Research Council and Academic Advisory Council. He previously served as the Intel executive sponsor for Cornell University on the External Advisory Board for the College of Engineering. Rattner joined Intel in 1973. He was named its first principal engineer in 1979, its fourth Intel Fellow in 1988, and one of the first four senior fellows in 2002. Prior to joining Intel, Rattner held positions with Hewlett-Packard Company and Xerox Corporation. He received bachelor's and master's degrees from Cornell University in Electrical Engineering and Computer Science in 1970 and 1972, respectively. In 2012, Rattner was bestowed an honorary Doctor of Science from Willamette University in Salem, Oregon, where he delivered the commencement address to the Atkinson Graduate School of Management (AGSM). Rattner lives near Portland, Oregon where he and his three children own and operate a large equestrian competition and training facility.

Worked examples

Example 1 — a first encounter with Justin Rattner

Start with the simplest possible case. Write down what Justin Rattner 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 Justin Rattner 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 Justin Rattner 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 Justin Rattner

In research: Justin Rattner 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 Justin Rattner 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: Justin Rattner is common in secondary-school and first-year university syllabi. It links to neighbouring topics American businesspeople in the computer industry, American chief technology officers, Businesspeople from Portland, Oregon, so understanding it makes those chapters shorter.
In everyday life: Look for Justin Rattner 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.
