Messier 35 or M35, also known as NGC 2168, is an open cluster of stars in the northern constellation of Gemini. It was discovered by Philippe Loys de Chéseaux around 1745 and independently discovered by John Bevis before 1750. The cluster is scattered over an area of the sky almost the size of the full moon and is located 3,870 light-years from Earth. The compact open cluster NGC 2158 lies directly southwest of M35.
Within the field of photography, a toy camera refers to a simple, inexpensive film camera.
Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, hardness, modify electrical conductivity, remove burrs and other surface flaws, and control the surface friction. In limited cases some of these techniques can be used to restore original dimensions to salvage or repair an item. An unfinished surface is often called mill finish.
Engine balance refers to those factors in the design, production, engine tuning, maintenance and the operation of an engine that benefit from being balanced. Major considerations are:
11 Andromedae, abbreviated 11 And, is a single, orange-hued star in the northern constellation of Andromeda. 11 Andromedae is the Flamsteed designation. It has an apparent visual magnitude of 5.44, which is bright enough to be faintly visible to the naked eye. An annual parallax shift of 11.5 mas yields a distance estimate of 283 light years. It is moving further from the Earth with a heliocentric radial velocity of +10 km/s.
66 Cancri is a binary star system near the northern border of the zodiac constellation of Cancer, located 474 light years away from the Sun. It is visible to the naked eye as a faint, white-hued star with a combined apparent visual magnitude of 5.87. The pair are moving closer to the Earth with a heliocentric radial velocity of −13 light years. As of 2003, the magnitude 8.56 companion was located at an angular separation of 4.43″ along a position angle of 134° from the primary.
North Brookfield High School is a public high school in North Brookfield, Massachusetts. The school serves the residents of North Brookfield exclusively, making it one of the smallest high schools in the region. Recently, a new building was built next to the old one. The construction was completed in 2006. NBHS was founded in 1857, making 2007 its 150th anniversary.
The Sputnik rocket was an unmanned orbital carrier rocket designed by Sergei Korolev in the Soviet Union, derived from the R-7 Semyorka ICBM. On 4 October 1957, it was used to perform the world's first satellite launch, placing Sputnik 1 into a low Earth orbit.

Gott, man lobet dich in der Stille, BWV 120.1, is a sacred cantata by Johann Sebastian Bach. He composed it in Leipzig for the occasion of Ratswechsel, the inauguration of a new town council in a church service, probably before 1730, or, alternatively, in 1742. Parts of the cantata appeared in a wedding cantata and a cantata commemorating the Augsburg Confession in 1730. Bach reworked the choral second movement for the Symbolum Nicenum of his Mass in B minor.
Deuterium fusion, also called deuterium burning, is a nuclear fusion reaction that occurs in stars and some substellar objects, in which a deuterium nucleus and a proton combine to form a helium-3 nucleus. It occurs as the second stage of the proton–proton chain reaction, in which a deuterium nucleus formed from two protons fuses with another proton, but can also proceed from primordial deuterium.
Kaibōkan or coastal defense ship is a type of naval ship used by the Imperial Japanese Navy during World War II for escort duty and coastal defense. The term escort ship is used by the United States Navy to describe this category of Japanese ships.
The Adams decarboxylation is a chemical reaction that involved the decarboxylation of coumarins which have carboxylic acid group in the third position. The decarboxylation is achieved by aqueous solution of sodium bisulfite, heat and a concentrated solution of sodium hydroxide.
2-Hydroxy-4-methylbenzaldehyde is a chemical compound. It is an additives in cigarettes.
Kosmos 120 or Zenit-2 No.41 was a Soviet optical film-return reconnaissance satellite launched in 1966. A Zenit-2 spacecraft, Kosmos 120 was the thirty-ninth of eighty-one such satellites to be launched and had a mass of 4,730.0 kilograms (10,427.9 lb).
V4998 Sagittarii is a luminous blue variable star (LBV) in the constellation of Sagittarius. Located some 25,000 light years away, the star is positioned ~7 pc away from a starburst cluster known as the Quintuplet cluster. It has an ejection nebula measuring over 0.8 pc in diameter, formed 5000-10,000 years ago through large eruptions. The star has a large mass comparable to the Pistol star and a luminosity of ~4,000,000 times the Sun (L☉). This places the star as one of the most massive and luminous stars known.
Formaldoxime is the organic compound with the formula H2C=NOH. It is the oxime of formaldehyde. A colorless liquid, the pure compound tends to polymerize into a trimer. Aqueous solutions are stable as is the hydrochloride. It is a reagent in organic synthesis for the conversion of aryl diazonium salts to aryl aldehydes.
