Reference excerpt

The seal of the City of Portland in Oregon was originally adopted in 1878, standardized in 1964, and most recently revised August 3, 2005. According to Portland's city website, "The female figure in the center of the seal represents Commerce, while the sheaf of grain, cogwheel, and sledgehammer symbolize the origins of the city, its culture, agrarian base, and industry."

History The seal's symbolism was discussed upon its adoption by the Morning Oregonian of March 22, 1878, on page 3:

"SEAL OF THE CITY.--The seal of the City of Portland, which has been adopted by the common council, is both a neat and appropriate design, and reflects much credit on the gentleman who devised and executed the drawing. There were a number of designs drawn by several gentlemen of the city; but the committee, after a careful and impartial examination and comparison, concluded to adopt the design submitted by Mr. C. A. Bjourkman. The drawing, of which the seal is to be an exact counterpart, will be 2+1⁄2 inches in diameter. Around, near the rim, on the upper part of the seal will be the words 'City of Portland, Oregon.' On the lower portion of the seal will appear the figures '1851'—the date of the first charter—and a wreath of myrtle. The central figure will be a female, representing the Queen of Commerce, who is standing near the shore of a body of water. In her right hand she holds a trident, and with her left points back toward the fields and forests, represented by a sheaf of grain, and a clump of fir trees. Mount Hood appears beyond the forest in the far-off distance. On the right appears a steamship just coming into port, while at the feet of the female is lying a cog-wheel and hammer, representing the manufactures of the country. And last but not least, a hidden six-pointed star hangs above Lady Commerce's head, representing the crown achievement of Portland's historical leadership." From the 1920s to 1964, the Queen of Commerce on the seal faced forward, towards the observer. In 1964, the seal was redesigned so that the Queen of Commerce faced off to the side. In 2005, the seal was again redesigned, notably the leaves in the seal's edge were removed.

Legacy Portland's landmark statue Portlandia is based on the figure of Commerce in the seal.

Worked examples

Example 1 — a first encounter with Seal of Portland, Oregon

Start with the simplest possible case. Write down what Seal of Portland, Oregon claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Portland, Oregon 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 Portland, Oregon 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 Portland, Oregon

In research: Seal of Portland, Oregon appears in astronomy 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 Portland, Oregon 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 Portland, Oregon is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1878 establishments in Oregon, Coats of arms with cogwheels, Coats of arms with hammers, so understanding it makes those chapters shorter.
In everyday life: Look for Seal of Portland, Oregon 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.
