Vilho Väisälä
Vilho Väisälä (; September 28, 1889 – August 12, 1969) was a Finnish meteorologist and physicist, and founder of Vaisala Oyj. After graduation in mathematics in 1912, Väisälä worked for the Finnish Meteorological Institute in ''aerological measurements'', specializing in the research of the higher troposphere. At the time the measurements were conducted by attaching a thermograph to a kite. In 1917 he published his dissertation in mathematics ''Ensimmäisen lajin elliptisen integralin käänteisfunktion yksikäsitteisyys'' (The single-valuedness of the inverse function of the elliptic integral of the first kind). His dissertation was the first and still is the only mathematical doctoral thesis written in the Finnish language.Lehto, Olli: Oman tien kulkijat. Helsinki: Otava, 2004. . Page 101 Väisälä participated in development of radiosonde, a device attached to a balloon and launched to measure air in the higher atmosphere. In 1936 he started his own company, ...

Finns
Finns or Finnish people ( fi, suomalaiset, ) are a Baltic Finnic ethnic group native to Finland. Finns are traditionally divided into smaller regional groups that span several countries adjacent to Finland, both those who are native to these countries as well as those who have resettled. Some of these may be classified as separate ethnic groups, rather than subgroups of Finns. These include the Kvens and Forest Finns in Norway, the Tornedalians in Sweden, and the Ingrian Finns in Russia. Finnish, the language spoken by Finns, is closely related to other Balto-Finnic languages, e.g. Estonian and Karelian. The Finnic languages are a subgroup of the larger Uralic family of languages, which also includes Hungarian. These languages are markedly different from most other languages spoken in Europe, which belong to the Indo-European family of languages. Native Finns can also be divided according to dialect into subgroups sometimes called ''heimo'' (lit. ''tribe''), although suc ...

Esperanto Movement
The Esperanto movement, less commonly referred to as Esperantism ( eo, Esperantismo), is a movement to disseminate the use of the planned international language Esperanto.See the definition in theDeklaracio pri la Esenco de la Esperantismo ("Bulonja Deklaracio", 1905) The movement does not aim to supplant national languages but merely to supplement them. The movement is sometimes used to describe all speakers of Esperanto including their culture. Politics Esperanto has been placed in a few proposed political situations. The most popular of these is the former minor party '' Europe—Democracy—Esperanto'', which aims to establish Esperanto as the official language of the European Union. Grin's Report, published in 2005 by François Grin found that the use of the English language as the ''lingua franca'' within the European Union costs billions annually and significantly benefits English-speaking countries The following is a list of English-speaking population by country, ...

Academic Staff Of The University Of Helsinki
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ...

Brunt–Väisälä Frequency
In atmospheric dynamics, oceanography, asteroseismology and geophysics, the Brunt–Väisälä frequency, or buoyancy frequency, is a measure of the stability of a fluid to vertical displacements such as those caused by convection. More precisely it is the frequency at which a vertically displaced parcel will oscillate within a statically stable environment. It is named after David Brunt and Vilho Väisälä. It can be used as a measure of atmospheric stratification. Derivation for a general fluid Consider a parcel of water or gas that has density \rho_0. This parcel is in an environment of other water or gas particles where the density of the environment is a function of height: \rho = \rho (z). If the parcel is displaced by a small vertical increment z', ''and it maintains its original density, so that its volume does not change,'' it will be subject to an extra gravitational force against its surroundings of: :\rho_0 \frac = - g \left[\rho (z)-\rho (z+z')\right] where g is the ...

World Congress Of Esperanto
The World Esperanto Congress ( eo, Universala Kongreso de Esperanto, UK) is an annual Esperanto convention. It has the longest tradition among international Esperanto conventions, with an almost unbroken run for 113 years. The congresses have been held since 1905 every year, except during World War I, World War II, and the COVID-19 pandemic. Since the 1920s, the Universal Esperanto Association has been organizing these congresses. These congresses take place every year and, over the 30 years from 1985 through 2014, have gathered an average of about 2,000 participants (since World War II World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great power ... it has varied from 800 to 6,000, depending on the venue).

Esperanto
Esperanto ( or ) is the world's most widely spoken constructed international auxiliary language. Created by the Warsaw-based ophthalmologist L. L. Zamenhof in 1887, it was intended to be a universal second language for international communication, or "the international language" (). Zamenhof first described the language in '' Dr. Esperanto's International Language'' (), which he published under the pseudonym . Early adopters of the language liked the name ''Esperanto'' and soon used it to describe his language. The word translates into English as "one who hopes". Within the range of constructed languages, Esperanto occupies a middle ground between "naturalistic" (imitating existing natural languages) and ''a'priori'' (where features are not based on existing languages). Esperanto's vocabulary, syntax and semantics derive predominantly from languages of the Indo-European group. The vocabulary derives primarily from Romance languages, with substantial contributions from Ge ...

Meteorologist
A meteorologist is a scientist who studies and works in the field of meteorology aiming to understand or predict Earth's atmospheric phenomena including the weather. Those who study meteorological phenomena are meteorologists in research, while those using mathematical models and knowledge to prepare daily weather forecasts are called ''weather forecasters'' or ''operational meteorologists''. Meteorologists work in government agencies, private consulting and research services, industrial enterprises, utilities, radio and television stations, and in education. They are not to be confused with weather presenters, who present the weather forecast in the media and range in training from journalists having just minimal training in meteorology to full fledged meteorologists. Description Meteorologists study the Earth's atmosphere and its interactions with the Earth's surface, the oceans and the biosphere. Their knowledge of applied mathematics and physics allows them to understand the ...
