Reference excerpt

Ott's Assay Office is a historic assay office located at 130 Main Street in Nevada City, California. The building was constructed in 1851 as a drug store; James J. Ott opened his assay office in the back of the store in 1857. In 1859, Ott assayed a sample of silver ore discovered in the Washoe Country; this ore marked the discovery of the Comstock Lode, and the resulting silver rush eventually led to Nevada's statehood and several advancements in mining technology. The silver rush also gave Ott a reputation as a quality assayer; he ran his office until his death in 1907, and his son continued the business until 1955. The adjoining building, which shares a common wall and is often considered part of the same building, was built in 1855. It served as the offices of the South Yuba Canal Company, which was formed in 1851 to bring water to the gold mines north of Nevada City. The company owned the oldest mining ditches in California, and it was the first in the United States to provide water to gravel mining operations. By 1855, it had become California's largest ditch company. The buildings were added to the National Register of Historic Places on April 14, 1975.

Worked examples

Example 1 — a first encounter with Ott's Assay Office

Start with the simplest possible case. Write down what Ott's Assay Office 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 Ott's Assay Office 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 Ott's Assay Office 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 Ott's Assay Office

In research: Ott's Assay Office 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 Ott's Assay Office 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: Ott's Assay Office is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1851 establishments in California, California Registered Historic Place stubs, Commercial buildings completed in 1851, so understanding it makes those chapters shorter.
In everyday life: Look for Ott's Assay Office 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.
