The zenith is an imaginary point directly "above" a particular location, on the imaginary celestial sphere. "Above" means in the vertical direction opposite to the apparent gravitational force at that location. The opposite direction, i.e. the direction in which gravity pulls, is toward the nadir. The zenith is the "highest" point on the celestial sphere; the word "zenith" derives from an inaccurate reading of the Arabic expression سمت الرأس, meaning "direction of the head" or "path above the head", by Medieval Latin scribes in the Middle Ages through Old Spanish. It was reduced to "samt" and miswritten as "senit"/"cenit", the "m" being misread as "ni". Through the Old French "cenith", "zenith" first appeared in the 17th century; the term zenith is sometimes used to refer to the highest point, way, or level reached by a celestial body on its daily apparent path around a given point of observation. This sense of the word is used to describe the position of the Sun, but to an astronomer, the Sun does not have its own zenith and is at the zenith only if it is directly overhead.

In a scientific context, the zenith is the direction of reference for measuring the zenith angle, the angle between a direction of interest and the local zenith - that is, the complement of the altitude. The Sun reaches the observer's zenith when it is 90° above the horizon, this only happens between the Tropic of Cancer and the Tropic of Capricorn. At a given location during the course of a day, the Sun reaches not only its zenith but its nadir, at the antipode of that location 12 hours from solar noon. In astronomy, the altitude in the horizontal coordinate system and the zenith angle are complementary angles, with the horizon perpendicular to the zenith; the astronomical meridian is determined by the zenith, is defined as a circle on the celestial sphere that passes through the zenith and the celestial poles. A zenith telescope is a type of telescope designed to point straight up at or near the zenith, used for precision measurement of star positions, to simplify telescope construction, or both.

The NASA Orbital Debris Observatory and the Large Zenith Telescope are both zenith telescopes since the use of liquid mirrors meant these telescopes could only point straight up. On the International Space Station and nadir are used instead of up and down, referring to directions within and around the station, relative to the earth.

Sergey Grinevich is a Belarusian painter. Grinevich was born in 1960 in the Byelorussian Soviet Socialist Republic near Grodno, a town with 370,000 inhabitants, near the border with Poland and Lithuania. From 1971 to 1978 he was a student in the city's Republican school of Fine Art. In 1978 he began his studies at the Belarusian State Academy of Arts, where he graduated in 1983, he has taken part in art exhibitions since 1982. Sergey Grinevich is now one of the most influential artists in Belarus. Together with Juri Jacovenko, Valentina Choba, Vladimir Panteleev and Victoria Iliyna, he is a member of an artist group there. In his paintings, he combines motifs from the past and creates in a sampling principle using the colorful and serial principles of Andy Warhol or the style of the striking and symbolically shortened visual worlds of Erik Bulatov and Alex Katz icons of a critical life and present, his criticism is directed against the ubiquitous consumer world, the power of the military and traditional religious symbols, against environmental degradation.

He transforms elements of the iconography and the insignia of socialist realism, mixes the motifs to images based on several levels and accentuates the paintings ironica. Artist about himself: I have painted all my life and, oddly enough, with every year there appear more and more mysteries in this profession for me; this permanent intrigue, the desire to get closer to the unknown keeps me in the profession, which in the great scheme of things is not a profession, but my life choice... 2019 Beijing International Art Biennale, China.2018 National Museum, China Tyzenhaus gallery, Grodno2017 Gallery Nebo, Ukraine DK gallery, Minsk2016 DK gallery, Minsk Museum Erarta, Sankt Petersburg Art Zurich 2016 Art-Riga 20162015 Hall Luzan, Spain „Novi Zamok“, Belarus New Castle, Grodno Art-Monaco, Monte Carlo2014 Rothause, Switzerland National Museum, Belarus Bel-Expo, Belarus Art-Zabor project, Belarus Art-Zabor project, Paris2013 ArtPalm Beach 2013, Florida, USA Agart gallery, Poland Nebo gallery, Ukraine Art- Southampton, NY, USA Museum of Contemporary Art, Belarus2012 Grodno exhibition hall, Belarus De Twee Pauwen gallery, The Haag, Netherland Kryga gallery, Belarus Gallery ZPAP, Poland „Sady Pobedy“ gallery, Ukraine Gallery of Siaulu University, Lithuania Rothause, Kreuzlingen Switzerland 1 Triennial of contemporary art, Expocenter, Belarus2011 Gallery Wystawa, Poland Y Gallery, Belarus2010 Central Artist House, Russia Kryga gallery, Belarus International plain-air of Mark Rothko, Latvia Art-Kyiv contemporary, Ukraine Agart, art gallery, Poland2009 Belarusian pavilion, BelExpo, Belarus Fine-art gallery, Belarus Art-Kyiv contemporary, Ukraine Region museum, Belarus „Sady Pobedy“ gallery, Ukraine2008 International festival „Traditional and contemporaneity“, the Manezh, Russia Art gallery, Belarus2007 Art-Manezh, Russia „Mastatstva“ gallery, Belarus2006 National Museum of Fine Art, Belarus Grodno exhibition hall, Belarus „Anixis“ gallery, Swiss „U Maistra“ gallery, Belarus Covalenco gallery, Netherlands 2005 Mastatstva gallery, Belarus „Espace Pierre Cardin“, France2004 Municipal Museum, France Palace „OssolineumWroclaw, Poland „Paradis“ gallery, Russia2003 municipal Museum, France2002 „U Maistra“ gallery, Belarus "Mastatstva“ gallery, Belarus „Author design" salon, Russia2001 „Mastatstva“ gallery, Belarus „Anixis“ gallery, Swiss2000 Museum of Modern Art, Belarus „Amatininkaj“ gallery, Lithuania „Anixis“ gallery, Swiss „Art felchlin“ gallery, Switzerland1999 II international symposium „Sulecin“, Poland „U Maistra“ gallery, Belarus Gallery of Belarusian union of artists, Belarus1998 The international exhibition Expo-98, Russia The international Artist Settlement "Berkshire", New York, USA1997 The II International Chagall symposium, Belarus The II International Biennale „Dialogues“, St. Petersburg, Russia "U Maistra" gallery, Belarus1996 The Center of Fine Arts „Zhylbel“, Belarus1995 „U Maistra“ gallery, Belarus1994 The Alternative theatre, Belarus1993 Gallery of Belarusian union of artists, Belarus Gallery „Goya“ of Aragon’s union of artists, Spain Municipal gallery, Spain „Barbasan“ gallery, Spain1992 Gallery AL-Kaunas, Lithuania Gallery AL-Palanga, Lithuania1991 International symposium „Byelovezha-91“, premium of The Union of Polish Artists and Designers Friedrich Kisters: Sergey Grinevich Blick und Richtung, published in Switzerland by Human Bios GmbH, Kreuzlingen Language: German ISBN 3-03742-002-2.
