Street clock

Street clock is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Street clock rather than just read about it. In short: A street clock or post clock is a clock mounted on top of a post typically installed in a streetscape or other urban or park setting. History A less common kind of street clock can be found on Maiden Lane in Manhattan, New York.

Key takeaways

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

Reference excerpt

A street clock or post clock is a clock mounted on top of a post typically installed in a streetscape or other urban or park setting.

History A less common kind of street clock can be found on Maiden Lane in Manhattan, New York. In the late 19th century, William Barthman Jewelers had a clock embedded in the sidewalk. As of 2014, the clock remains visible and maintained.

Manufacturers

Past street clock manufacturers in the United States E. Howard & Co. Brown Street Clock Company Seth Thomas Clock Company Self Winding Clock Company – produced public clocks including street clocks; one surviving example was later restored by the Electric Time Company. Joseph Mayer & Bros. (Seattle, Washington) O.B. McClintock Company (Minneapolis, Minnesota)

Current street clock manufacturers in the United States Electric Time Company The Verdin Company

Worked examples

Example 1 — a first encounter with Street clock

Start with the simplest possible case. Write down what Street clock 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 Street clock 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 Street clock 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 Street clock

In research
Street clock 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 Street clock 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
Street clock is common in secondary-school and first-year university syllabi. It links to neighbouring topics Clock designs, Furniture stubs, Standards and measurement stubs, so understanding it makes those chapters shorter.
In everyday life
Look for Street clock 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.
