Reference excerpt

The Seal of the City and County of San Francisco includes a shield, crest, supporters and a motto, ringed with the municipality's name.

History That a corporate seal of the City and County of San Francisco bearing upon its face: A shield supported by a miner on the left and a sailor on the right, with a device of a steamship passing the Golden Gate. At the foot of the supporters emblems of commerce, navigation, and mining. Crest, Phoenix issuing from flames. Motto, "oro en Paz, Fierro en Guerra" (Gold in Peace, Iron in War). Around the margins the words, "Seal of the City and County of San Francisco." The current seal was adopted in 1859 by the Board of Supervisors, and superseded a similar seal that had been adopted seven years earlier. The shield shows the Golden Gate and the hills on each side as it looked in 1859, and a paddlewheel steamship entering San Francisco Bay. Above the shield is a crest with a phoenix, the legendary Greek bird rising from the ashes. The shield is flanked by two supporters: a miner, in dexter, holding a shovel; and a sailor, in sinister, holding a sextant. Both figures wear 1850s period clothing. At the feet of the supporters are a plow and anchor, emblems of commerce and navigation. Below the shield is a motto that reads "Oro en paz, fierro en guerra", which is Spanish for "Gold in peace, iron in war". The official de jure description of the seal given by the San Franciscan government does not assign any specific colors to be used on renditions of the seal.

Worked examples

Example 1 — a first encounter with Seal of San Francisco

Start with the simplest possible case. Write down what Seal of San Francisco 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 Seal of San Francisco 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 Seal of San Francisco 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 Seal of San Francisco

In research: Seal of San Francisco 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 Seal of San Francisco 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: Seal of San Francisco is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1859 establishments in California, Coats of arms with birds, Coats of arms with buildings, so understanding it makes those chapters shorter.
In everyday life: Look for Seal of San Francisco 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.
