Key takeaways

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

Reference excerpt

John James Speed, Jr. (July 20, 1803 – June 15, 1867) was an American farmer, merchant, politician, and pioneer in telegraphy.

Biography Speed was born in Mecklenburg County, Virginia, on July 20, 1803, and his family moved to Caroline, New York, in 1807. Speed was educated in Caroline and became a farmer before relocating to Ithaca to become a merchant. In 1832 he married Anne Sophia Morrell, an aunt of Theodore L. Cuyler. He was active in the New York Militia in the 1820s and 1830s, and became commander of a regiment with the rank of colonel. A Whig in politics, in 1832 he was elected to the New York State Assembly, and in 1838 he was elected a trustee of the village of Ithaca as well as Town Supervisor of the town of Ithaca. In 1843 he was elected President of the village trustees. In 1840 he was a presidential elector, and cast his ballot for William Henry Harrison and John Tyler. Speed lost his mercantile fortune in the Panic of 1837 and turned to telegraphy to recover. In the 1840s he experimented with both visual and electric telegraphs. In Ithaca he was friends with Ezra Cornell and together they became agents for Samuel Morse's partner Francis Ormand Jonathan Smith, who had become the agent for the Morse patent in the states of Michigan, Ohio, Indiana, Illinois, and Wisconsin. Smith contracted with Cornell and Speed in 1847 to build a line from Buffalo to Detroit, Chicago and Milwaukee, and Speed moved to Detroit. Speed built the section from Detroit west. He made a sub-contract with Jeptha Wade for the construction of a line from Detroit to Jackson, the first line completed west of Buffalo in the summer of 1847. When the line reached Chicago it was organized at the Erie and Michigan Telegraph Company with Speed as President. Direct contact was established between Chicago and Buffalo in January, 1849. However, the line was not well constructed and revenues were initially small. Speed and Taliferro Shaffner connected the eastern and western hemispheres with a line from Greenland, Iceland and the Faroe Islands. During the American Civil War he constructed a telegraph line from Washington, D.C. to Portland, Maine. He continued to invent, and received patents for his improvements to the telegraph. In his later years he left the telegraph business and became involved in iron manufacturing.

Death Speed died in Brooklyn, New York, on June 15, 1867. He was buried at Green-Wood Cemetery.

Worked examples

Example 1 — a first encounter with John James Speed

Start with the simplest possible case. Write down what John James Speed 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 John James Speed 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 John James Speed 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 John James Speed

In research
John James Speed 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 John James Speed 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
John James Speed is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1803 births, 1840 United States presidential electors, 1867 deaths, so understanding it makes those chapters shorter.
In everyday life
Look for John James Speed 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.
