Key takeaways

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

Reference excerpt

The schooner Hassler was the first iron-hulled steamship used in the service of the United States Coast Survey.

Ship history Plans for a new ship to chart the waters of U.S. Pacific Coast were drawn up in early 1870 by Carlile Patterson, the hydrographic inspector of the U.S. Coast Survey. Patterson called for an iron-hulled ship of about 325 gross tons, with a draft of no more than 9 feet (2.7 m) and a top speed of 8 knots (15 km/h; 9.2 mph). He required that the ship use no more than 2½ tons of coal per day and could hold up to two months of provisions for a crew of 37. The resulting ship was built in 1871 at the River Iron Works in Camden, New Jersey, under the supervision of John H. Dialogue. She was a three-masted schooner equipped with a 125 hp (93 kW) steeple compound engine, and cost US$62,000 to build. In 1871-1872 the ship sailed on the Hassler Expedition, under Commander Philip Carrigan Johnson, brother of the artist Eastman Johnson. This was the first major scientific expedition sent by the government for marine exploration. The expedition included Professor Louis Agassiz and his wife Elizabeth Agassiz; Mrs. Johnson; Dr. Franz Steindachner, ichthyologist; Dr. Thomas Hill, botanist; Count L. F. de Pourtalès, Joel Asaph Allen, James Henry Blake, and others. The steamer left Boston December 4, 1871, and reached San Francisco in August 1872. On the way to St. Thomas surface observations were made. Deep-sea dredging was done at Barbados and along the Brazilian coast. At the Straits of Magellan frequent stops were made, and at particularly interesting places several days were spent, and inland excursions undertaken, especially to examine glaciers. Throughout the route collections were made, with much of this material deposited in the Museum of Comparative Zoology at Harvard University. Some of the zoological results of the expedition were published by Agassiz, Lyman, and Pourtalès. After nearly 25 years in service, mostly around the Alaskan coast, the Hassler was finally decommissioned on May 25, 1895. In August 1897 she was sold to the McGuire Brothers for $15,700, and renamed Clara Nevada. She sailed from Seattle on January 26, 1898, with a crew of 40 men, bound for Skagway, Alaska with 165 passengers heading for the Klondike gold fields. Late on February 5, 1898, the Clara Nevada left Skagway with between 25 and 40 passengers aboard. During the night she struck an uncharted rock several hundred yards north of Eldred Rock and sank immediately. There were no survivors.

Worked examples

Example 1 — a first encounter with Hassler (vessel)

Start with the simplest possible case. Write down what Hassler (vessel) 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 Hassler (vessel) 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 Hassler (vessel) 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 Hassler (vessel)

In research
Hassler (vessel) 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 Hassler (vessel) 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
Hassler (vessel) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1871 ships, Maritime incidents in 1898, Research vessels of the United States, so understanding it makes those chapters shorter.
In everyday life
Look for Hassler (vessel) 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.
