Simplified molecular-input line-entry system
The simplified molecular-input line-entry system (SMILES) is a specification in form of a line notation for describing the structure of chemical species using short ASCII strings. SMILES strings can be imported by most molecule editors for conversion back into two-dimensional drawings or three-dimensional models of the molecules.
The original SMILES specification was initiated by David Weininger at the USEPA Mid-Continent Ecology Division Laboratory in Duluth in the 1980s. Acknowledged for their parts in the early development were "Gilman Veith and Rose Russo (USEPA) and Albert Leo and Corwin Hansch (Pomona College) for supporting the work, and Arthur Weininger (Pomona; Daylight CIS) and Jeremy Scofield (Cedar River Software, Renton, WA) for assistance in programming the system." The Environmental Protection Agency funded the initial project to develop SMILES.
It has since been modified and extended by others, most notably by Daylight Chemical Information Systems. In 2007, an open standard called "OpenSMILES" was developed by the Blue Obelisk open-source chemistry community. Other 'linear' notations include the Wiswesser Line Notation (WLN), ROSDAL and SLN (Tripos Inc).
42 Isis
42 Isis /ˈaɪsᵻs/ is a large main-belt asteroid, measuring 100.2 km in diameter. It was discovered by N.R. Pogson on May 23, 1856, at Oxford. It was Pogson's first asteroid discovery.
The asteroid's name was chosen by Manuel John Johnson, director of the Radcliffe Observatory in Oxford. Although Isis is the name of an Egyptian goddess, the name was chosen in homage to Pogson's astronomer daughter, (Elizabeth) Isis Pogson. In addition, the Isis is the stretch of the River Thames that runs through Oxford.
The light curve inversion technique, when applied to photometric observations of this asteroid, show multiple local irregularities. The overall shape displays little elongation, with a ratio between the major and minor axes equal to 1.1. The measured rotation period for this model is 13.59701 hours. The spectrum of 42 Isis reveals the strong presence of the mineral Olivine, a relatively rarity in the asteroid belt.

Isis (rapper)
Lin Que (born Lin Que Ayoung 7 September 1969) is a female hip-hop artist. She graduated from Cathedral High School in Manhattan in 1987. She was a member of the hip-hop collective known as the Blackwatch Movement (which included X Clan) as Isis. She released her debut album Rebel Soul while affiliated with that group in 1990.
Lin Que left X-Clan to work with MC Lyte. No longer Isis, she rhymed as Lin Que and released a couple of singles for SME Records and Elektra Records. She eventually went into A&R work and graphic design, and she appeared briefly in Spike Lee's He Got Game and Ted Demme's Who's the Man?
She collaborated with various artists such as Will Downing, Mary J. Blige, Queen Latifah, MC Lyte, Smif-N-Wessun, The Beatnuts, Monifah, Ce Ce Peniston, and more.
She had a brief stint as a member of the Wu-Tang Clan-affiliated group Deadly Venoms. After leaving the group for business reasons shortly after its debut album was recorded and never released, she remained writing and creating music with producers Sugar Al Cayne, Azteknique, and Ayatollah. She has written for MC Lyte and has been producing music as well.
