Key takeaways

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

Reference excerpt

Rosemary Jeanne Redfield is a microbiologist associated with the University of British Columbia where she worked as a faculty member in the Department of Zoology from 1993 until retiring in 2021.

Education Redfield completed her undergraduate degree in biochemistry at Monash University. She continued her education at McMaster University where she completed her MSc in 1980. Her thesis titled, "Methylation and chromatin conformation of adenovirus type 12 DNA sequences in transformed cells," dealt with the chromatin structure and SDNA methylation. Redfield received her PhD in Biological Sciences from Stanford University under Allan M. Campbell.

Research and career Redfield completed postdoctoral work at Harvard University with Richard Charles Lewontin and Johns Hopkins School of Medicine with Hamilton O. Smith, an American microbiologist and 1978 Nobel Laureate. She played an early role in the refutation of the GFAJ-1 "arsenic life" results of Felisa Wolfe-Simon. She joined University of British Columbia as a faculty member in 1993, primarily researching natural competence in bacteria, and has advocated for transparency in the research process. She retired in 2021.

Worked examples

Example 1 — a first encounter with Rosemary Redfield

Start with the simplest possible case. Write down what Rosemary Redfield claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Rosemary Redfield 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 Rosemary Redfield 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 Rosemary Redfield

In research: Rosemary Redfield appears in biology 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 Rosemary Redfield 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: Rosemary Redfield is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of the University of British Columbia, Canadian microbiologists, Canadian women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Rosemary Redfield 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.
