Key takeaways

John B. Bell (mathematician) belongs to mathematics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect John B. Bell (mathematician) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of John B. Bell (mathematician) from memory before moving on to harder problems.

Reference excerpt

John B. Bell is an American mathematician and the Chief Scientist of the Computational Research Division at the Lawrence Berkeley National Laboratory. He has made contributions in the areas of finite difference methods, numerical methods for low Mach number flows, adaptive mesh refinement, interface tracking and parallel computing. He has also worked on the application of these numerical methods to problems from a broad range of fields, including combustion, shock physics, seismology, flow in porous media and astrophysics.

Career Bell received his Ph.D. from Cornell University in 1979. Following a three-year stint at the Naval Surface Weapons Center, he spent four years at Exxon Production Research, where he was the group leader of the Applied Mathematics Group in the Long Range Research Division. He worked at Lawrence Livermore National Laboratory from 1986 until 1996, when he joined Lawrence Berkeley National Laboratory. He is currently the Chief Scientist in LBNL's Computational Research Division of the Computing Sciences Area. He was one of the founders and is the current managing editor of Communications in Applied Mathematics and Computational Science (CAMCOS).

Awards and honors In 2018, Bell received the Berkeley Lab Prize Lifetime Achievement Award for "intellectual and strategic leadership in applied mathematics at LBNL, and for design and development of sophisticated numerical strategies to address critical scientific problems in support of DOE’s research missions.". In 2012, Bell was elected to the National Academy of Sciences. He is also a Fellow of the Society for Industrial and Applied Mathematics (SIAM). He is the recipient of the Sidney Fernbach Award from the IEEE Computer Society in 2005, given each year to one person who has made "an outstanding contribution in the application of high performance computers using innovative approaches. He also received the SIAM/ACM prize for computational science and engineering in 2003.

Worked examples

Example 1 — a first encounter with John B. Bell (mathematician)

Start with the simplest possible case. Write down what John B. Bell (mathematician) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 John B. Bell (mathematician) 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 John B. Bell (mathematician) 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 John B. Bell (mathematician)

In research: John B. Bell (mathematician) appears in mathematics 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 John B. Bell (mathematician) 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: John B. Bell (mathematician) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1954 births, 20th-century American mathematicians, 21st-century American mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for John B. Bell (mathematician) 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.
