Zinaida Aksentyeva
Zinaïda Mikolaïevna Aksentieva ( uk, Зінаїда Миколаївна Аксентьєва; July 25, 1900 – April 8, 1969) was a Ukrainian/Soviet astronomer and geophysicist. Life Aksentieva or Aksentyeva was born in Odessa in 1900. She graduated from Odessa Institute of Public Education in 1924. She worked on mapping gravity and her observatory was one of the first to be able to accurately find the centre of the earth. She worked in Poltava Observatory. She became observatory director in 1951. Her areas of study were tidal deformation of the earth and gravimeter Earth profiles. She has a crater on Venus that is named in her honour. The scientist was the first to organize a study of slope fluctuations at great depths in the mines of Kryvorizhye, Donbass, Carpathians, and the first in the USSR to observe tidal changes in gravity using a gravimeter. Together with like-minded people, she prepared a general program of stars for latitudinal observations in Poltava and Irkutsk ...

Odessa
Odesa (also spelled Odessa) is the third most populous city and municipality in Ukraine and a major seaport and transport hub located in the south-west of the country, on the northwestern shore of the Black Sea. The city is also the administrative centre of the Odesa Raion and Odesa Oblast, as well as a multiethnic cultural centre. As of January 2021 Odesa's population was approximately In classical antiquity a large Greek settlement existed at its location. The first chronicle mention of the Slavic settlement-port of Kotsiubijiv, which was part of the Grand Duchy of Lithuania, dates back to 1415, when a ship was sent from here to Constantinople by sea. After a period of Lithuanian Grand Duchy control, the port and its surroundings became part of the domain of the Ottomans in 1529, under the name Hacibey, and remained there until the empire's defeat in the Russo-Turkish War of 1792. In 1794, the modern city of Odesa was founded by a decree of the Russian empress Catherine t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Craters On Venus
This is a list of craters on Venus, named by the International Astronomical Union's (IAU) Working Group for Planetary System Nomenclature. All craters on Venus are named after famous women or female first names. ''(For features on Venus other than craters see, list of montes on Venus and List of coronae on Venus.)'' As of 2017, there are 900 named craters on Venus, fewer than the lunar and Martian craters but more than on Mercury. Other, non-planetary bodies with numerous named craters include Callisto ( 141), Ganymede ( 131), Rhea (128), Vesta (90), Ceres (90), Dione (73), Iapetus (58), Enceladus (53), Tethys (50) and Europa ( 41).

Scientists From Odesa
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Gravimeter
Gravimetry is the measurement of the strength of a gravitational field. Gravimetry may be used when either the magnitude of a gravitational field or the properties of matter responsible for its creation are of interest. Units of measurement Gravity is usually measured in units of acceleration. In the SI system of units, the standard unit of acceleration is 1 metre per second squared (abbreviated as m/s2). Other units include the cgs gal (sometimes known as a ''galileo'', in either case with symbol Gal), which equals 1 centimetre per second squared, and the '' g'' (''g''n), equal to 9.80665 m/s2. The value of the ''g''n is defined approximately equal to the acceleration due to gravity at the Earth's surface (although the value of ''g'' varies by location). Gravimeters An instrument used to measure gravity is known as a gravimeter. For a small body, general relativity predicts gravitational effects indistinguishable from the effects of acceleration by the equivalence pri ...

Russian Empire
The Russian Empire was an empire and the final period of the Russian monarchy from 1721 to 1917, ruling across large parts of Eurasia. It succeeded the Tsardom of Russia following the Treaty of Nystad, which ended the Great Northern War. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China. It also held colonies in North America between 1799 and 1867. Covering an area of approximately , it remains the third-largest empire in history, surpassed only by the British Empire and the Mongol Empire; it ruled over a population of 125.6 million people per the 1897 Russian census, which was the only census carried out during the entire imperial period. Owing to its geographic extent across three continents at its peak, it featured great ethnic, linguistic, religious, and economic diversity. From the 10th–17th centuries, the land ...

Poltava Observatory
Poltava (, ; uk, Полтава ) is a city located on the Vorskla River in central Ukraine. It is the capital city of the Poltava Oblast (province) and of the surrounding Poltava Raion (district) of the oblast. Poltava is administratively incorporated as a city of oblast significance and does not belong to the raion. It has a population of History It is still unknown when Poltava was founded, although the town was not attested before 1174. However, for reasons unknown, municipal authorities chose to celebrate the city's 1100th anniversary in 1999. The settlement is indeed an old one, as archeologists unearthed a Paleolithic dwelling as well as Scythian remains within the city limits. Middle Ages The present name of the city is traditionally connected to the settlement Ltava which is mentioned in the Hypatian Chronicle in 1174.

Geophysicist
Geophysics () is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. The term ''geophysics'' sometimes refers only to solid earth applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial physics; and analogous problems associated with the Moon and other planets.
