Reference excerpt

Petro Evstaf'evic Stojan (Russian: Пётр Евстафьевич Стоян, also known by the pseudonyms Ribaulb, Radovich and Šulerc) (June 22, 1884 in Izmail, Bessarabia — May 3, 1961 in Nice) was a Russian esperantist, bibliographer and lexicographer and a member of the Esperanto Language Committee (Lingva Komitato) from 1914.

Life and work Stojan studied physics and mathematics at the Richelieu Lyceum (today's Odesa University) in Odesa and in Sankt Petersburg and from 1906 to 1907 in Paris. From 1919 to 1922, he was a high school teacher in Serbia. From 1925, he worked at the Universal Esperanto Association in Geneva at its biggest work, the Bibliography of the International Language (Bibliografio de Internacia Lingvo) which was published in 1929. He spent the end of his life in Southern France where he died of drowning.

Engagement with Esperanto He joined the Esperanto movement in 1903. According to the Encyclopedia of Esperanto of 1933, "he was one of the most competent regarding the dictionary technique." Over sixteen years, he worked on twelve dictionaries; among them are the great Russian dictionary of the Imperial Academy. His other well-known dictionaries are the Ornithological Eight-language Dictionary (1911) and the Small Russian-Esperanto dictionary and the Illustrated Dictionary of the Russian Language (760 pages and 2000 pictures). In 1929, his Bibliography of the International Language (Bibliografio de Internacia Lingvo) was published. In 1913, he proposed the creation of the Universal Card Encyclopedia (Universala Slipa Enciklopedio, USE) which, according to his idea, could be updated by adding cards for each subject. He also wrote a great number of scientific articles and original literature in Esperanto.

Vindiania and Biosophy In France he worked on La Vindiania, a thesis on the origin of the Indo-European languages and on a complete philosophy of life, which he named biosophy (in Esperanto - Biozofio). However, his works remained in the manuscript form and circulated among his friends, and only one book was actually published in 1946 in Arras.

Constructed languages Stojan created a number of constructed languages. As an esperantologist he created variants based on Esperanto:

Eo (an esperantido with very short radicals, proposed in 1926 under the pseudonym Ribaulb) Espo (1926, a pra-form of Eo created under the pseudonym Ribaulb, which does not use the Esperanto correlatives but a naturalistic system of Ido; unpublished) He possibly created also a number of new languages as fictional languages, simply for his amusement; but in his time, the concept did not exist. Most of which were never published.

Amiana (an evolved form of Ariana, first presented in 1919 and its final version appeared in 1922) Ariana or Aryana (1912, an esperantido whose vocabulary was based on Pre-Indo-European (Aryan) radicals; pre-form of Amiana) Idido Liana Linga franka Renova Spiranta Uniala (1923, with P. J. Troost) Unita an unnamed Pan-Slavic language (1913–16, with D. Chupovsky)

Worked examples

Example 1 — a first encounter with Petro Stojan

Start with the simplest possible case. Write down what Petro Stojan 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 Petro Stojan 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 Petro Stojan 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 Petro Stojan

In research: Petro Stojan 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 Petro Stojan 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: Petro Stojan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1884 births, 1961 deaths, 20th-century Russian linguists, so understanding it makes those chapters shorter.
In everyday life: Look for Petro Stojan 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.
