Reference excerpt

Pietari (Petter) Mikonpoika Hannikainen, surname changed to Hanén during his early years of studying until 1852, (August 24, 1813 Sääminki – September 27, 1899 Parikkala) was a Finnish writer, journalist and surveyor, and a member of the Hannikainen family of writers and musicians.

Life Hannikainen was born to parents Mikael Abrahamsson Hannikainen (b.1771), a farmowner and county judge from Sääminki Kiilanmäki, and to Katarina Löppönen (b.1785), his father’s second wife. The composer Pekka Juhani Hannikainen was Pietari Hannikainen’s nephew. He graduated in 1833 and continued studying at the University of Helsinki. During a time of Fennomania in Finland he was one of the first students to complete an examination of Finnish language. He became highly involved in the promotion of the Finnish language and in 1851 he also took back his original name of Hannikainen, which had been changed to Hanén when he started school. It was also in 1851 that he bought a farm in Parikkala where he lived until his death in 1899. He is buried in Parikkala. Pietari Hannikainen was married to Katarina Margareta Krank (b. 1862) from 1854 to 1862. After the death of his first wife he married Emilia Savander (b. 1910) in 1864. His children from these two marriages were sons August Edvard Hannikainen (1854-1939) Hiittinen district Hitis representative, Peter Woldemar Hannikainen (1858-1928) general director of the Finnish Forest Administration Metsähallitus and State Councillor (Russia), Karl Onni Gerhard Hannikainen (1865-1930) author and rector of Kuopio Lyceum, Tauno Robert Alarik Hannikainen (1868-1953) Antrea district Kamenogorsk doctor and councillor of medicine, and daughters Armias Forsblom (1860-1946) she and her husband were tenant housekeepers of the Koitsanlahti Manor, Fanny Vilhelmiina Ilmoni (1854-1934) mother of Finnish painter Einar Ilmoni who was a student of Helene Schjerfbeck.

Career Hannikainen became a deputy surveyor in 1835 and received the title of surveyor in 1843. He worked as a deputy surveyor in Viipuri Province from 1849 as a permanent commission surveyor in 1857–1866, as a permanent commissioner 1866–1874 and as a senior commissioner 1874–1879. Parallel to his work as a surveyor Hannikainen became deeply involved in linguistic and literary aspects of Fennomania writing numerous plays and works in Finnish and working as a journalist and editor for the newspaper Kanawa. The newspaper was considered as the Finnish version of the Swedish language newspaper Saima which at the time was run by Johan Vilhelm Snellman. The Kanawa newspaper was published in Vyborg between 1845 and 1847. It dealt with religious and state (political) issues. Snellmann, who was a prominent Fennoman philosopher, often translated articles from Hannikainen’s Kanawa and printed them in Saima. Kanawa was closed down by the authorities in 1847. Hannikainen later contributed to several newspapers, such as Suometar Uusi Suomi, of which he was the editor-in-chief until 1848. His play Silmänkääntäjä, ie Jussi Oluvisen matka Hölmölään (The Conjurer, ie Jussi Oluvisen’s travel to Foolsville), the very first publicly presented play in Finnish language, was first performed in Lappeenranta in 1846 and then in Kuopio in 1847. Hannikainen already wrote the play end of 1830, when he was working as a surveyor's assistant in Hölmölä village in Ruokolahti. In total, Hannikainen wrote nine plays, four of which were unpublished. Hannikainen also wrote poems and translated numerous works including plays by authors such as Ludvig Holberg, William Shakespeare and Miguel de Cervantes. The words he forged or introduced into the general Finnish language are modern, guardian, publicity, profitability, gaze, accounting, accountant, craftsman, business, sales, council, name (verb), act (verb), pre-school, people’s school, learning school (see Education in Finland), share (noun), dividend, purchase, print, protocol, heroism, commit, conjugate (words), financial, commission (noun), wholesaler, future, import, photograph, vice judge (varatuomari), society, community and vowel.

Worked examples

Example 1 — a first encounter with Pietari Hannikainen

Start with the simplest possible case. Write down what Pietari Hannikainen claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Pietari Hannikainen 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 Pietari Hannikainen 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 Pietari Hannikainen

In research
Pietari Hannikainen appears in astronomy 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 Pietari Hannikainen 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
Pietari Hannikainen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1813 births, 1899 deaths, 19th-century Finnish writers, so understanding it makes those chapters shorter.
In everyday life
Look for Pietari Hannikainen 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.
