Telegram

Telegram 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 Telegram rather than just read about it. In short: A telegram is a written or printed message, originally sent through telegraphy. The use of the telegrams was popular for social and business correspondence in the latter half of the 19th and the first half of the 20th century.

Key takeaways

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

Reference excerpt

A telegram is a written or printed message, originally sent through telegraphy. The use of the telegrams was popular for social and business correspondence in the latter half of the 19th and the first half of the 20th century. Even in the telephone age, the telegram remained popular, and spawned its own style of writing that in turn persisted in other media. Telegram services still exist today, though the popularity has largely waned, replaced by other forms of text communication.

Terminology Initially, telegrams were sent by an electrical telegraph operator or telegrapher using Morse code, or a printing telegraph operator using plain text. A cablegram was a message sent by a submarine telegraph cable, often shortened to "cable" or "wire". The suffix -gram is derived from ancient Greek: γραμμα (gramma), meaning something written, i.e. telegram means something written at a distance and cablegram means something written via a cable, whereas telegraph implies the process of writing at a distance.

Delivery services

A telegram service is a company or public entity that delivers telegrams directly to the recipient. Telegram services were inaugurated after electric telegraphy became available. Historically, telegrams were sent between a network of interconnected telegraph offices. A person visiting a local telegraph office paid by the word to have a message telegraphed to another office and delivered to the addressee on a paper form. Messages (i.e. telegrams) sent by telegraph could be delivered by telegraph messenger faster than mail. The electric telegraph freed communication from the time constraints of postal mail and revolutionized society and the global economy. A decline that began with the growth of the use of the telephone was briefly postponed by the rise of special occasion congratulatory telegrams. Traffic continued to grow between 1867 and 1893 despite the introduction of the telephone in this period. At their peak in 1929, an estimated 200 million telegrams were sent. In 1919, the Central Bureau for Registered Addresses was established in the financial district of New York City. The bureau was created to ease the growing problem of messages being delivered to the wrong recipients. To combat this issue, the bureau offered telegraph customers the option to register unique code names for their telegraph addresses. Customers were charged $2.50 per year per code. By 1934, 28,000 codes had been registered. Telegram services still operate in much of the world. However, e-mail and text messaging have rendered telegrams obsolete in many countries, and the number of telegrams sent annually has been declining rapidly since the 1980s. Where telegram services still exist, the transmission method between offices is no longer by telegraph, but by telex or IP link.

Length and style As telegrams have been traditionally charged by the word, messages were often abbreviated to pack information into the smallest possible number of words, in what came to be called "telegram style". The average length of a telegram in the 1900s in the US was 11.93 words; more than half of the messages were 10 words or fewer. According to another study, the mean length of the telegrams sent in the UK before 1950 was 14.6 words or 78.8 characters. For German telegrams, the mean length is 11.5 words or 72.4 characters. At the end of the 19th century, the average length of a German telegram was calculated as 14.2 words.

Derived uses A diplomatic telegram is a confidential communication between a diplomatic mission and the foreign ministry of its parent country. These continue to be called telegrams or cables regardless of the method used for transmission.

Worked examples

Example 1 — a first encounter with Telegram

Start with the simplest possible case. Write down what Telegram 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 Telegram 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 Telegram 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 Telegram

In research
Telegram 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 Telegram 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
Telegram is common in secondary-school and first-year university syllabi. It links to neighbouring topics Documents, Telecommunications, Telegrams, so understanding it makes those chapters shorter.
In everyday life
Look for Telegram 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.

Frequently asked questions

What is Telegram in simple terms?

A telegram is a written or printed message, originally sent through telegraphy. The use of the telegrams was popular for social and business correspondence in the latter half of the 19th and the first half of the 20th century.

Why does Telegram matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Telegram?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
