Reference excerpt

The Sperm Bank of California (TSBC) is a nonprofit sperm bank in Berkeley, California. It was founded by Barbara Raboy in 1982. It has a program through which adults conceived from a sperm donation can contact the donor, which was first such program offered by a sperm bank. Many of the donors at the sperm bank take part in this program. According to a 2002 article, at the time 1,100 children had been conceived with the help of the bank and officials of the bank said roughly four out of five clients had chosen the donor ID release option. The bank serves a large lesbian and single-mother-by-choice clientele.

Worked examples

Example 1 — a first encounter with The Sperm Bank of California

Start with the simplest possible case. Write down what The Sperm Bank of California claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 The Sperm Bank of California 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 The Sperm Bank of California 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 The Sperm Bank of California

In research: The Sperm Bank of California appears in 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 The Sperm Bank of California 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: The Sperm Bank of California is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Berkeley, California, Non-profit organizations based in California, Sperm banks, so understanding it makes those chapters shorter.
In everyday life: Look for The Sperm Bank of California 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.
