Gustaf Gabriel Hällström
Gustaf Gabriel Hällström (25 November 1775 – 2 June 1844) was a Finnish scientist. He was active in several fields, contributing to the establishment of an astronomical observatory in Turku as well as initiating the earliest systematic meteorological observations in Finland. His children were ennobled in recognition of his achievements. Biography Gustaf Gabriel Hällström was born in Ilmajoki, Finland on 25 November 1775. He entered the Royal Academy of Turku as a student in 1792 and made a rapid career as an academic. He would remain tied to the academy throughout his life, also after it moved to Helsinki in 1827, becoming president of the university (today known as Helsinki University) for several years. He was made a professor of physics already in 1801, after having abandoned his initial studies in mathematics. He published his research widely, mainly in the form of dissertations and in ', the scientific journal of the Royal Swedish Academy of Sciences, as well as in the ...

Theology
Theology is the study of religious belief from a Religion, religious perspective, with a focus on the nature of divinity. It is taught as an Discipline (academia), academic discipline, typically in universities and seminaries. It occupies itself with the unique content of analyzing the supernatural, but also deals with religious epistemology, asks and seeks to answer the question of revelation. Revelation pertains to the acceptance of God, gods, or deity, deities, as not only transcendent or above the natural world, but also willing and able to interact with the natural world and to reveal themselves to humankind. Theologians use various forms of analysis and argument (Spirituality, experiential, philosophy, philosophical, ethnography, ethnographic, history, historical, and others) to help understanding, understand, explanation, explain, test, critique, defend or promote any myriad of List of religious topics, religious topics.

Aurora
An aurora ( aurorae or auroras), also commonly known as the northern lights (aurora borealis) or southern lights (aurora australis), is a natural light display in Earth's sky, predominantly observed in high-latitude regions (around the Arctic and Antarctic). Auroras display dynamic patterns of radiant lights that appear as curtains, rays, spirals or dynamic flickers covering the entire sky. Auroras are the result of disturbances in the Earth's magnetosphere caused by enhanced speeds of solar wind from coronal holes and coronal mass ejections. These disturbances alter the trajectories of charged particles in the magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere ( thermosphere/exosphere). The resulting ionization and excitation of atmospheric constituents emit light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frost
Frost is a thin layer of ice on a solid surface, which forms from water vapor that deposits onto a freezing surface. Frost forms when the air contains more water vapor than it can normally hold at a specific temperature. The process is similar to the formation of dew, except it occurs below the freezing point of water typically without crossing through a liquid state. Air always contains a certain amount of water vapor, depending on temperature. Warmer air can hold more than colder air. When the atmosphere contains more water than it can hold at a specific temperature, its relative humidity rises above 100% becoming supersaturated, and the excess water vapor is forced to deposit onto any nearby surface, forming seed crystals. The temperature at which frost will form is called the dew point, and depends on the humidity of the air. When the temperature of the air drops below its dew point, excess water vapor is forced out of solution, resulting in a phase change directly fro ...

Friedrich Wilhelm Argelander
Friedrich Wilhelm August Argelander (22 March 1799 – 17 February 1875) was a German astronomer. He is known for his determinations of stellar brightnesses, positions, and distances. Life and work Argelander was born in Memel in the Kingdom of Prussia (now Klaipėda in Lithuania), the son of a father of Finnish descent, Johann Gottlieb Argelander, and German (Prussian) mother, Dorothea Wilhelmina Grünhagen. He studied with Friedrich Bessel, whose assistant he became in 1820, and obtained his Ph.D. in 1822 at University of Königsberg. From 1823 until 1837, Argelander was the head of the Finnish observatory, first in Turku and then in Helsinki. He then moved to Bonn, Germany. There he designed and built a new observatory at the University of Bonn with funding approved directly by King Frederick William IV whom Argelander had become friends with in his childhood. This lifelong friendship had started when the then crown prince temporarily lived in Argelander's parents hou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henrik Johan Walbeck
Henrik Johan Walbeck (11 October 1793 – 23 October 1822) was a Finnish geodesist and astronomer who studied the size and figure of the Earth by means of arc measurements. Walbeck was born in Turku (Åbo). In 1817, he was made a corresponding member of the Royal Swedish Academy of Sciences and, in 1820, of the Royal Astronomical Society and the Mathematische Gesellschaft in Hamburg. He committed suicide in 1822, also in Åbo.''Uppslagsverket Finland'', vol. 3, p. 480. The asteroid 1695 Walbeck is named after him.

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysics, oceanography and volcanology are examples of disciplines for which observatories have been constructed. The term ''observatoire'' has been used in French since at least 1976 to denote any institution that compiles and presents data on a particular subject (such as public health observatory) or for a particular geographic area (European Audiovisual Observatory). Astronomical observatories Astronomical observatories are mainly divided into four categories: space observatory, space-based, airborne observatory, airborne, ground-based, and underground-based. Historically, ground-based observatories were as simple as containing a mural instrument (for measuring the angle between stars) or Stonehenge (which has some alignments on astronomical phenomena). Ground-based observatories Ground-based observatories, located on the surface of Earth, are u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In music, the organ is a keyboard instrument of one or more Pipe organ, pipe divisions or other means (generally woodwind or electronic musical instrument, electric) for producing tones. The organs have usually two or three, sometimes up to five or more, manuals for playing with the hands and a pedalboard for playing with the feet. With the use of registers, several groups of pipes can be connected to one manual. The organ has been used in various musical settings, particularly in classical music. Music written specifically for the organ is common from the Renaissance to the present day. Pipe organs, the most traditional type, operate by forcing air through pipes of varying sizes and materials, each producing a different pitch and tone. These instruments are commonly found in churches and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
