68 (number)
68 (sixty-eight) is the natural number following 67 (number), 67 and preceding 69 (number), 69. It is an Parity (mathematics), even number. In mathematics 68 is a Perrin number. It is the largest known number to be the sum of two primes in exactly two different ways: 68 = 7 + 61 = 31 + 37. All higher even numbers that have been checked are the sum of three or more pairs of primes; the conjecture that 68 is the largest number with this property is closely related to the Goldbach conjecture and, like it, remains unproven. Because of the factorization of 68 as , a 68-sided regular polygon may be constructed with compass and straightedge. There are exactly 68 10-bit binary numbers in which each bit has an adjacent bit with the same value, exactly 68 combinatorially distinct Point-set triangulation, triangulations of a given triangle with four points interior to it, and exactly 68 Partially ordered set#Intervals, intervals in the Tamari lattic ...

Prime Number
A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, or , involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4. Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product of primes that is unique up to their order. The property of being prime is called primality. A simple but slow method of checking the primality of a given number n, called trial division, tests whether n is a multiple of any integer between 2 and \sqrt. Faster algorithms include the Miller–Rabin primality test, which is fast but has a small chance of error, and the AKS primality test, which always pr ...

Visual Magnitude
Apparent magnitude () is a measure of the brightness of a star or other astronomical object observed from Earth. An object's apparent magnitude depends on its intrinsic luminosity, its distance from Earth, and any extinction of the object's light caused by interstellar dust along the line of sight to the observer. The word ''magnitude'' in astronomy, unless stated otherwise, usually refers to a celestial object's apparent magnitude. The magnitude scale dates back to the ancient Roman astronomer Claudius Ptolemy, whose star catalog listed stars from 1st magnitude (brightest) to 6th magnitude (dimmest). The modern scale was mathematically defined in a way to closely match this historical system. The scale is reverse logarithmic: the brighter an object is, the lower its magnitude number. A difference of 1.0 in magnitude corresponds to a brightness ratio of \sqrt /math>, or about 2.512. For example, a star of magnitude 2.0 is 2.512 times as bright as a star of magnitude 3.0, ...

Commonly nicknamed the "Rocket Man" after his 1972 hit single of the same name, John has led a commercially successful career as a solo artist since the 1970s, having released 31 albums since 1969. Collaborating with lyricist Bernie Taupin since 1967, John is acclaimed by critics and musicians, particularly for his work during the 1970s, and his lasting impact on the music industry. John's music and showmanship have had a significant impact on popular music. His songwriting partnership with Taupin is one of the most successful in history. John was raised in the Pinner suburb of London and learned to play piano at an early age, forming the blues band Bluesology in 1962.

Questions 67 And 68
"Questions 67 and 68" is a 1969 song written by Robert Lamm for the rock band Chicago (then known as Chicago Transit Authority) and recorded for their debut album ''Chicago Transit Authority''. It was their first single release. Peter Cetera is the primary lead singer with Lamm also on vocals. In 2015, Dave Swanson, writing for ''Ultimate Classic Rock'', listed the song as ninth in a list of top ten Chicago songs. Writing for ''Rock Cellar'' magazine, Frank Mastropolo rated the song as number 11 in a list of "Top 11 Question Songs". Lyrics and music The questions in "Questions 67 and 68" relate to the nature of a romantic relationship Lamm had during 1967 and 1968. In 2008, Lamm said, " 'It’s about a girl I knew during those years with a hint of acid imagery and very Beatles influenced.' " The lyrics include the title phrase only as the last words. With respect to the horn arrangement, James Pankow said in a 2000 '' Goldmine'' article, " 'In the old days, however, I used to wr ...

Chicago (band)
Chicago is an American rock music, rock band formed in Chicago, Illinois, in 1967. The group began calling themselves the Chicago Transit Authority in 1968, then shortened the name in 1969. Self-described as a "rock and roll band with Horn (instrument), horns", Chicago's songs often combine elements of classical music, jazz, R&B, and pop music. Growing out of several bands from the Chicago area in the late 1960s, the line-up consisted of Peter Cetera on bass, Terry Kath on guitar, Robert Lamm on keyboards, Lee Loughnane on trumpet, James Pankow on trombone, Walter Parazaider on Woodwind instrument, woodwinds, and Danny Seraphine on drums. Cetera, Kath, and Lamm shared lead vocal duties. Laudir de Oliveira joined the band as a percussionist and second drummer in 1974. Kath died in 1978, and was replaced by several guitarists in succession. Bill Champlin joined in 1981, providing vocals, keyboards, and rhythm guitar. Cetera left the band in 1985 and was replaced by Jason Scheff. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Car 67
"Car 67" is a novelty song by 'Driver 67' released in November 1978. It was in the UK Singles Chart for twelve weeks, reaching a high of No. 7 in February 1979. The song is a ballad revolving around a cab driver who had split up with his girlfriend the previous day and how he is refusing to make a particular pick-up at 83 Royal Gardens (the passenger, unbeknownst to the controller, is the woman in question). The song is arranged as the taxi driver singing the lyrics, interspersed with the voice of the taxi controller; the latter of whom has a distinctive West Midlands accent. Background and release Paul Phillips and his brother-in-law Pete Zorn formed the group Tax Loss in 1976. The band signed with Logo Records in 1978 and whilst negotiating a deal for an album, Phillips wrote "Car 67". At the time, Phillips was a taxi driver, which he has described himself as being "so bad as a cabbie, I never earned enough to pay the rent on the radio". He wrote the song within minutes and ...

Andromeda (constellation)
Andromeda is one of the 48 constellations listed by the 2nd-century Greco-Roman astronomer Ptolemy, and one of the 88 modern constellations. Located in the northern celestial hemisphere, it is named for Andromeda, daughter of Cassiopeia, in the Greek myth, who was chained to a rock to be eaten by the sea monster Cetus. Andromeda is most prominent during autumn evenings in the Northern Hemisphere, along with several other constellations named for characters in the Perseus myth. Because of its northern declination, Andromeda is visible only north of 40° south latitude; for observers farther south, it lies below the horizon. It is one of the largest constellations, with an area of 722 square degrees. This is over 1,400 times the size of the full moon, 55% of the size of the largest constellation, Hydra, and over 10 times the size of the smallest constellation, Crux. Its brightest star, Alpha Andromedae, is a binary star that has also been counted as a part of Pegasus, while ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elliptical Galaxy
An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. They are one of the four main classes of galaxy described by Edwin Hubble in his Hubble sequence and 1936 work ''The Realm of the Nebulae'', with their intermediate scale disks, a subset of the "early-type" galaxy population. Most elliptical galaxies are composed of older, low-mass stars, with a sparse interstellar medium and minimal star formation activity, and they tend to be surrounded by large numbers of globular clusters. Elliptical galaxies are believed to make up approximately 10–15% of galaxies in the Virgo Supercluster, and they are not the dominant type of galaxy in the universe overall. They are preferentially found close to the centers of galaxy clusters. Elliptical galaxies range in size from dwarf ellipticals with tens of millions of stars, to supergiants of over one hundred trillion stars that dominate their galaxy clusters. Original ...

NGC 67
NGC 67 is an elliptical galaxy located in the constellation Andromeda that was discovered on October 7, 1855, by R. J. Mitchell, who described it as "extremely faint, very small, round". The galaxy belongs to the NGC 68 group, which also contains the galaxies NGC 68, NGC 69, NGC 70, NGC 71, NGC 72, and possibly NGC 74. Target galaxy controversy Mitchell's position locates the observed galaxy between an E3 elliptical and an E5 elliptical on the edge of the galaxy group, and each elliptical has been interpreted as the original and secondary.
