  • Reproduce the core statement of Simon F. Blunt from memory before moving on to harder problems.

Reference excerpt

Simon Fraser Blunt (August 1, 1818 – April 27, 1854) was a member of the Wilkes Expedition, Cartographer of San Francisco Bay and was Captain of the SS Winfield Scott when it shipwrecked off Anacapa Island in 1853. Two geographic features, Blunt Cove and Point Blunt are named for him.

Wilkes Expedition Blunt joined the U.S. Navy, and in 1838, he was assigned to the USS Porpoise, under the command of Captain C. Ringgold. He passed the midshipman examination on June 23, before the ship joined the Wilkes Expedition in early August. In March 1839, while at Orange Bay, Blunt transferred to the USS Vincennes. On January 16, 1840, the expedition sailed close enough to Antarctica to see the actual continent; Blunt Cove is named after him. Blunt took sick in April, 1841 in Honolulu, possibly from participating in the trip to the summit of Mauna Loa Volcano. The Expedition reached Oregon on April 28, and explored the coast from there to San Francisco Bay. He was promoted to Lieutenant on July 28, 1842, a few weeks after the expedition had arrived back in New York.

Intermediate years In 1844–45, Blunt was assigned to the USS Truxtun in activities off the coast of Liberia. On January 27, 1846, Blunt married Ellen Lloyd Key, daughter of Francis Scott Key, in Washington D.C. The couple had three children. In 1848, John Y. Mason named his son after Blunt.

Charting San Francisco Bay In 1849, Blunt was appointed to a Joint Commission of Army and Navy Officers (Joint Commission) whose purpose was to identify potential sites for lighthouses and defense facilities along the Pacific Coast of the California and Oregon territories. The Joint Commission consisted of three army engineers: Maj. John L. Smith, Maj Cornelius Austin Ogden and 1st Lt. Danville Leadbetter; and three naval officers: Comdr Louis M. Goldsborough, Comdr. G.J. Van Brunt, and Blunt. and had assembled in San Francisco by early April 1849. Blunt, either on his own or with the rest of the members of the Joint Commission presumably joined his former Captain on the Porpoise, now "Commodore" C. Ringgold on the chartered brig Col. Fremont to chart the San Francisco Bay region, suddenly important because of the discovery of gold in the area. Ringgold named Point Blunt on Angel Island for him. Afterwards, Blunt assisted Commodore Ringgold in the creation of two charts:

Chart of the Farallones and entrance to the Bay of San Francisco, California (1850) Chart of the Bay of San Pablo, Straits of Carquinez, and part of the Bay of San Francisco (1850) Blunt also drew a lithograph, View of Benicia from the anchorage east of Seal Island for Ringgold's Chart of Suisun & Vallejo bays with the confluence of the rivers Sacramento and San Joaquin, California A colored version of the lithograph was published in 1852. The Joint Commission may have been joined by members of the land branch of the Pacific division of the United States Coast Survey (Pacific Coast Survey), James S. Williams and Richard P. Hammond who were unable to find boats to charter and James Blair. The USS Massachusetts was transferred to the Navy in San Francisco on August 1, 1849, and detailed for the use of the Joint Commission to take up and down the coast, however they could not recruit a crew. They borrowed some crewmen from another ship and Blunt may have made his second trip to Hawaii, where the Massachusetts wintered and hired native crewmen. Upon its return, the Joint Commission made preliminary recommendations to President Fillmore to reserve various islands and coastal regions in and around San Francisco Bay. then they and the Massachusetts sailed up to Puget Sound. After a cursory examination of the mouth of the Columbia River, the ship and the Joint Commission returned to California in July 1850. After a trip to San Diego, the Joint Commission made its final recommendation on November 30, 1850.

Activities on the Pacific Coast If Blunt went with the Joint Commission to Hawaii, immediately upon his return he separated from it and the Massachusetts. On March 10, 1850 Blunt was in command of the Schooner Arabian with another military survey party en route to Trinidad Bay. Upon reaching the bay, a boat with a landing party from the schooner swamped, resulting in the drowning of five men: Lieutenants Richard Bache and Robert L. Browning, John H. Peoples, W. W. Cheshire and John Purdy. Five more men survived. Blunt appears to have continued to the Columbia River and explored the Willamette Valley, and by August 1, 1850, to have attached to the Survey Schooner Ewing of the Pacific Coast Survey. In a letter of that date from William Pope McArthur (the first leader of the hydrographic branch of the Pacific Coast Survey) to his father-in-law Commander John J. Young, McArthur wrote: "Lt. Blunt who is now with me has traveled considerably through the country (the Willamette Valley) and is so much pleased with it, that he has taken a section of land and made a regular claim to it, he has also taken one for myself and one for Lt. Bartlett, both adjoining his!" (emphasis added). McArther was commander of Ewing, and Barlett one of its officers. (The Ewing had also wintered in Hawaii in 1849–50, giving opportunity for Blunt to become well acquainted with both men.) By August 31, 1850, Blunt was back in San Francisco, from which location he wrote to Mason The Ewing worked its way south to San Diego then returned to San Francisco, and both McArthur and Barlett left for the east coast. At the end of December 1850, the Ewing was severely damaged in a storm while attempting to take the new land branch of the Pacific Coast Survey, George Davidson and James S. Lawson to Monterey Bay. Upon her repair, she traveled up the coast to the Columbia River. If Blunt was with the Ewing he was back by early to mid summer, when he was a signer of the constitution of the San Francisco Committee of Vigilance In August, he may have visited John Charles and Jessie Benton Frémont at their home in the same city. On January 15, 1852, Secretary of the Navy Will A. Graham ordered a Naval Commission to select a site for a Naval Yard. Blunt, along with Commodore D. Sloat Commodore C. Ringgold, and William P.S. Sanger (former overseer of construction of Drydock Number One, Norfolk Naval Shipyard) were appointed to the commission. On July 13, 1852, Sloat recommended Mare Island to Graham.

Worked examples

Example 1 — a first encounter with Simon F. Blunt

Start with the simplest possible case. Write down what Simon F. Blunt 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 Simon F. Blunt 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 Simon F. Blunt 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 Simon F. Blunt

In research
Simon F. Blunt 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 Simon F. Blunt 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
Simon F. Blunt is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1818 births, 1854 deaths, 19th-century American naval officers, so understanding it makes those chapters shorter.
In everyday life
Look for Simon F. Blunt 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.
