H. Irving Hancock

H. Irving Hancock is a physics 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 H. Irving Hancock rather than just read about it. In short: Harrie Irving Hancock (January 16, 1868 – March 12, 1922) was an American chemist and writer, mainly remembered as an author of children's literature and juveniles in the late 19th and early 20th centuries, and as having written a fictional depiction of a German invasion of the United States. Biography Hancock was born in Massachusetts on January 16, 1868.

Key takeaways

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

Reference excerpt

Harrie Irving Hancock (January 16, 1868 – March 12, 1922) was an American chemist and writer, mainly remembered as an author of children's literature and juveniles in the late 19th and early 20th centuries, and as having written a fictional depiction of a German invasion of the United States.

Biography Hancock was born in Massachusetts on January 16, 1868. His parents were William Henry and Laura (Oakes) Hancock. Hancock married Nellie Stein on December 21, 1887. They had two daughters, apparently adopted: Vivian Morris Hancock and Doris Hancock. A prolific author who liked to work at night, Hancock wrote for the New York Journal, the New York World, and Leslie's Weekly. Much of his writing was the kind of "Boy's books" initiated by the famous Stratemeyer Syndicate, based on the assumption (which proved hugely successful) that "boys want the thrill of feeling 'grown-up'" and that they like books which give them that feeling to come in series where the same heroes appear again and again. However, the bulk of Hancock's works in that genre appear to have been handled by publishers other than Stratemeyer. (A comprehensive list of his publications does not yet exist, the list appearing on this page being far from complete). For some time it was considered that, unlike other writers, he invariably used his own name, in the form "H. Irving Hancock". However, Edward T. LeBlanc and J. Randolph Cox, who researched the period's "dime novels", concluded that a series of books attributed to "Douglas Wells" were in fact written by Hancock. The same researchers recount that Hancock "had been a journalist for the Boston Globe from 1885 to 1890 [and] produced more than 50 serials for Norman Munro's juvenile magazine Golden Hours between 1889 and 1901." In 1898 Hancock travelled to Cuba with the US forces as one of several "embedded" reporters and published an account of his war experiences later the same year under the title What One Man Saw, Being the Personal Impressions of a War Correspondent in Cuba. He also reported on the US-Spanish war in the Philippines. His output included westerns, detective stories (set in New Orleans and in Asia), and historical adventures. China and Japan were the setting of such stories as 'The Great Tan-To; or Dick Brent's Adventures in Up-to-Date Japan'." Hancock was charged with perpetuating racial stereotypes in his depiction of the Chinese "Supervillain" Li Shoon in a series of stories published between 1915 and 1917". Conversely, he had a sympathetic attitude toward Japan, setting stories there and coauthoring a book on ju-jitsu with a noted Japanese adept in the art. Hancock's experience as a war correspondent provided inspiration for books about the Spanish–American War. He also published books on physical fitness and an Encyclopedia of Knowledge and Manners, and served as the editor of a "History of West Point". In a magazine article he warned of the dangers of smoking, at a time when such dangers were not widely known. He was also apparently a sports writer and an early Western expert on Jiu-Jitsu. Much of Hancock's writing had a patriotic character, his books and stories having a considerable proportion of military heroes placed in settings ranging from the American Revolutionary War, through the Spanish–American War and the First World War, and up to an imaginary German invasion of the United States (see following section). In addition to his writing activity, Hancock organized the Ferguson-Hancock Laboratories together with Prof. George A. Ferguson in 1908. Hancock died of liver ailments at his home, in Blue Point, Suffolk County, New York on March 12, 1922. Despite the enormous amount of material published by Hancock, some of his biographical details are not completely clear. The 1920 United States Federal Census contains the following: "H. Hancock, Birth: abt 1868 – Massachusetts Residence: 1920 – Brookhaven, Suffolk, New York". This seems to refer to Harrie Irving Hancock, but it is not completely certain—hence the above question mark following the date of his birth. According to Gene Horton of Blue Point, Hancock is buried in an unmarked grave at the Blue Point Cemetery. One Hancock book still in print is The Complete Kano Jiu-Jitsu (Judo), co-authored with Katsukuma Higashi and originally published by G. P. Putnam & Sons in 1905 in New York (presently republished by Dover Publications).

Worked examples

Example 1 — a first encounter with H. Irving Hancock

Start with the simplest possible case. Write down what H. Irving Hancock claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 H. Irving Hancock 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 H. Irving Hancock 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 H. Irving Hancock

In research
H. Irving Hancock appears in physics 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 H. Irving Hancock 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
H. Irving Hancock is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1868 births, 1922 deaths, American chemists, so understanding it makes those chapters shorter.
In everyday life
Look for H. Irving Hancock 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.
