Hinman collator

Hinman collator 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 Hinman collator rather than just read about it. In short: The Hinman collator, an early optical collator, was an opto-mechanical device for comparing pairs of documents for differences in the text. Documents that appeared similar were said to “collate”.

Key takeaways

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

Reference excerpt

The Hinman collator, an early optical collator, was an opto-mechanical device for comparing pairs of documents for differences in the text. Documents that appeared similar were said to “collate”. The collator resulted in rapid advances in the study of literary works. Invented by Charlton Hinman in the late 1940s, the device used lights and mirrors to superimpose images of the two documents so that differences in text alignment or wording stood out. This resulted in huge improvements in speed and efficiency compared to the traditional cross-referencing of texts by eye. The idea built on earlier work such as Carl Pulfrich's blink comparator used to help identify the former planet Pluto, and Hinman's work analysing aerial photographs during World War II. Hinman used his device to compare the many slightly different impressions of the First Folio of William Shakespeare's works. The printing and bookbinding processes used in the time of Shakespeare often resulted in variations in the pages bound into the final books, and the collator enabled Hinman to describe the exact order in which the Folios had been composited and printed. He used the collator to compare 55 different copies of the First Folio held by the Folger Shakespeare Library, and subsequently wrote about his findings in Printing and Proof-reading of the First Folio of Shakespeare in 1963. In the wake of Hinman's success, the device was purchased by a number of universities, libraries and other institutions (allegedly including the CIA). As more compact types of collator were developed in the 1960s, the last Hinman was built in 1978. In his 2002 survey of mechanical collators, Steven Escar Smith estimates from scattered records that as many as 59 Hinman Collators were produced, 41 of these surviving at the time of his survey's publication. A more portable collator was developed by Randall McLeod.

Worked examples

Example 1 — a first encounter with Hinman collator

Start with the simplest possible case. Write down what Hinman collator 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 Hinman collator 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 Hinman collator 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 Hinman collator

In research: Hinman collator 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 Hinman collator 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: Hinman collator is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bibliography, Optical devices, Textual scholarship, so understanding it makes those chapters shorter.
In everyday life: Look for Hinman collator 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.
