Reference excerpt

Ian Lewis (born 1961) is an American computer scientist who is the director of infrastructure investment for the University of Cambridge and previously the director of the University of Cambridge Computing Service from 2005 to 2014

Early life and education Lewis was born in Bradford. He earned a Bachelor of Science degree from the Queen Mary University of London and a PhD at the Department of Computer Science and Technology, University of Cambridge.

Career Lewis started his career in 1983 at IBM. He later worked at Morgan Stanley and Dresdner Kleinwort before becoming global CIO for Investment Banking at Merrill Lynch. He returned to the University of Cambridge in 2005 as the fourth director of the University Computing Service since its establishment as the Mathematical Laboratory in 1949. He was a member of the board of Computacenter from 2006 to 2013 and was also a board member for JANET between 2007 and 2011. He lived in New York City for 10 years, including the extended period of recovery of the World Financial Center associated with the September 11 attacks in 2001. During the attacks, he assisted victims in the Winter Garden Atrium before moving to a prepared Merrill Lynch disaster command center in Jersey City. In 2007, he was appointed an Honorary Commander of the United States Air Force.

Worked examples

Example 1 — a first encounter with Ian Lewis (computer scientist)

Start with the simplest possible case. Write down what Ian Lewis (computer scientist) 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 Ian Lewis (computer scientist) 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 Ian Lewis (computer scientist) 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 Ian Lewis (computer scientist)

In research: Ian Lewis (computer scientist) 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 Ian Lewis (computer scientist) 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: Ian Lewis (computer scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, Alumni of Queen Mary University of London, British computer scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Ian Lewis (computer scientist) 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.
