Hangman's Elm

Hangman's Elm 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 Hangman's Elm rather than just read about it. In short: Hangman's Elm, or simply "The Hanging Tree", is an English elm located at the northwest corner in Washington Square Park in Greenwich Village, Manhattan, New York City. It stood at 135 feet (41 m) tall when measured c. 2000, and has a diameter of 67 inches (1.7 m).

Key takeaways

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

Reference excerpt

Hangman's Elm, or simply "The Hanging Tree", is an English elm located at the northwest corner in Washington Square Park in Greenwich Village, Manhattan, New York City. It stood at 135 feet (41 m) tall when measured c. 2000, and has a diameter of 67 inches (1.7 m). In 1989, the New York City Department of Parks and Recreation determined that this English elm was 310 years old, although that was subsequently revised to "more than 300 years old". As a result, it is considered to be Manhattan's oldest, outliving Peter Stuyvesant's pear tree at the northeast corner of 13th Street and Third Avenue, and the great Tulip poplar at Shorakapkok in Manhattan's Inwood neighborhood. The earliest references to the elm as a "hanging tree" date from the late 19th century, long after the supposed hangings were said to have taken place. Recent extensive research into the park's history by both an archaeologist and a historian has shown that the tree was on a private farm until the land was bought by the city and added to Washington Square in 1827. No public records exist of hangings from this tree. The only recorded execution in this area was of Rose Butler, in 1820, for arson. She was hanged from a gallows in the city's potter's field, on the eastern side of Minetta Creek, about 500 feet (150 meters) from the elm; at that time, Minetta Creek ran in a shallow ravine between the potter's field and the farm where the elm stood.

Worked examples

Example 1 — a first encounter with Hangman's Elm

Start with the simplest possible case. Write down what Hangman's Elm 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 Hangman's Elm 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 Hangman's Elm 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 Hangman's Elm

In research: Hangman's Elm 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 Hangman's Elm 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: Hangman's Elm is common in secondary-school and first-year university syllabi. It links to neighbouring topics Greenwich Village, Individual elm trees, Individual trees in New York City, so understanding it makes those chapters shorter.
In everyday life: Look for Hangman's Elm 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.
