Trifid Nebula
The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region in the north-west of Sagittarius in a star-forming region in the Milky Way's Scutum-Centaurus Arm. It was discovered by Charles Messier on June 5, 1764. Its name means 'three-lobe'. The object is an unusual combination of an open cluster of stars, an emission nebula (the relatively dense, reddish-pink portion), a reflection nebula (the mainly NNE blue portion), and a dark nebula (the apparent 'gaps' in the former that cause the trifurcated appearance, also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers. The most massive star that has formed in this region is HD 164492A, an O7.5III star with a mass more than 20 times the mass of the Sun. This star is surrounded by a cluster of approximately 3100 young stars. Characteristics The Trifid Nebula was the subject of an investiga ...

Trifid Cipher
The trifid cipher is a classical cipher invented by Félix Delastelle and described in 1902. Extending the principles of Delastelle's earlier bifid cipher, it combines the techniques of fractionation and transposition to achieve a certain amount of confusion and diffusion: each letter of the ciphertext depends on three letters of the plaintext and up to three letters of the key. The trifid cipher uses a table to ''fractionate'' each plaintext letter into a trigram, mixes the constituents of the trigrams, and then applies the table in reverse to turn these mixed trigrams into ciphertext letters. Delastelle notes that the most practical system uses three symbols for the trigrams:In order to split letters into three parts, it is necessary to represent them by a group of three signs or numbers. Knowing that ''n'' objects, combined in trigrams in all possible ways, give ''n'' × ''n'' × ''n'' = ''n''3, we recognize that three is the only value for ''n''; two would only give 23 =� ...

Plessey
The Plessey Company plc was a British electronics, defence and telecommunications company. It originated in 1917, growing and diversifying into electronics. It expanded after World War II by acquisition of companies and formed overseas companies. It was listed on the London Stock Exchange and was a constituent of the FTSE 100 Index. In 1989, it was taken over by a consortium formed by GEC and Siemens which split the assets of the Plessey group. The majority of Plessey's defence assets were amalgamated into BAE Systems in 1999 when British Aerospace merged with the defence arm of GEC, Marconi Electronic Systems (MES). A small portion of the defence market, mostly embedded electronic systems and circuitcards remained with GE, formerly GE Fanuc and GE Intelligent Platforms (GE-IP) and now Abaco Systems based in Huntsville, Alabama, and in Towcester, Northamptonshire. The bulk of Plessey's telecommunications assets were acquired by Ericsson through its 2005 acquisition of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The triffid is a fictional tall, mobile, carnivorous plant species, created by John Wyndham in his 1951 novel ''The Day of the Triffids'', which has since been adapted for film and television. The word "triffid" has become a common reference in British English to describe large, invasive or menacing-looking plants. Fictional history Origins In The Day of the Triffids, the novel, the origin of the triffid species is never explained. The main character, Bill Masen speculates as follows: The The Day of the Triffids (film), 1962 film adaptation portrays them as extraterrestrial lifeforms transported to Earth by comets, contradicting the novel. In the The Day of the Triffids (1981 TV series), 1981 TV series, the triffids were the creation of real-life Soviet Union, Soviet biologist Trofim Lysenko.
