<Li> The New General Catalogue object NGC 47, a barred spiral galaxy in the constellation Cetus . This object is also designated as NGC 58 . </Li> <P> Forty - seven has been the favorite number of Pomona College, California, United States, since 1964 . A mathematical proof, written in 1964 by Professor Donald Bentley, supposedly demonstrates that all numbers are equal to 47 . However, Bentley offered it as a "joke proof" to further a popular student research project that listed real and imaginative "47 sightings". Bentley used the invalid proof to introduce his students to the concept of mathematical proofs . The proof used limits to show that the sum of the two equal sides of an isosceles triangle is equal to the base side . Bentley chose forty - seven as the base side, but he could have used any number . </P> <P> Joe Menosky graduated from Pomona College in 1979 and went on to become one of the story writers of Star Trek: The Next Generation . Menosky "infected" other Star Trek writers with an enthusiasm for the number 47 . As a result, 47, its reverse 74, its multiples, or combinations of 47 occur in a large number of episodes of the program and its spin - offs Star Trek: Deep Space Nine, Star Trek: Voyager, and Star Trek: Enterprise, usually in the form of dialogue, on - screen labels, or computer screens . For example: </P> <Ul> <Li> In the TNG episode "Darmok", the computer of the Enterprise reports to have found 47 occurrences of the word "Darmok" in its database . </Li> <Li> In Star Trek Generations, Scotty manages to beam up only 47 El - Aurians before their ship is destroyed by the energy ribbon . </Li> <Li> In the Voyager episode "Parallax", we learn that the Emergency Medical Holographic Channel is 47 and that the EMH has the experience of 47 individual medical officers . </Li> <Li> In the Voyager episode "Non Sequitur", Harry Kim lives in apartment 4 - G, G being the seventh letter of the alphabet . The intentionality of this reference to 47 was confirmed by Brannon Braga, the writer of that episode . </Li> <Li> In the 2009 film Star Trek, the Enterprise was built in Sector 47 of the Riverside Shipyards, and 47 Klingon ships are said to have been destroyed by Nero's ship, the Narada . </Li> </Ul>
