Daniel Kan

Daniel Marinus Kan (or simply Dan Kan) (August 4, 1927 – August 4, 2013) was a Dutch mathematician working in homotopy theory. He was a prolific contributor to the field for the last six decades, having authored or coauthored several dozen research papers and monographs. The general theme of his career had been abstract homotopy theory.

He was an emeritus professor at MIT, where he taught since the early 1960s. He received his Ph.D. at Hebrew University in 1955, under the direction of Samuel Eilenberg. His students include Aldridge K. Bousfield, William Dwyer, Stewart Priddy, and Jeffrey H. Smith.

He played a role in the beginnings of modern homotopy theory perhaps analogous to that of Saunders Mac Lane in homological algebra, namely the adroit and persistent application of categorical methods. His most famous work is the abstract formulation of the discovery of adjoint functors, which dates from 1958. The Kan extension is one of the broadest descriptions of a useful general class of adjunctions.

Daniel

Daniel is a masculine given name and a surname of Hebrew origin. It means, "God is my judge", and derives from two early biblical figures, primary among them Daniel from the Book of Daniel. It is a common given name for males, and is also used as a surname. It is also the basis for various derived given names and surnames.

Background

The name evolved into over 100 different spellings in countries around the world. Nicknames (Dan, Danny) are common in both English and Hebrew, although in some instances "Dan" may be a complete given name rather than a nickname. The name "Daniil" (Даниил) is common in Russia. Feminine versions (Danielle, Daniela, Daniella, Dani, Danitza) are prevalent as well. The Dutch names "Daan" and "Daniël" are also variations of Daniel. A related surname developed as a patronymic, Daniels. Other surnames derived from "Daniel" include McDaniel and Danielson.

In the United States, the U.S. Social Security Administration reports that Daniel has peaked as the fifth most popular name for newborns in 1985, 1990, 2007, and 2008. The U.S. Census Bureau reported that in the 2000 census, "Daniels" was the 182nd most common surname in the U.S., while "McDaniel" was ranked at 323, and "Daniel" (without a final "s") was ranked at 380.

Daniel (Bat for Lashes song)

"Daniel" is a song by English recording artist Bat for Lashes, from her second studio album, Two Suns. It is her best selling single to date, selling over 46,000 copies worldwide. The song was announced as the lead single from Two Suns in January 2009, then released as a digital download single on 1 March 2009, and as a 7" vinyl single on 6 April 2009. The track was written by Natasha Khan and produced by David Kosten, as with all tracks on the album. Ira Wolf Tuton from Yeasayer provided the bass lines for the song and Khan did the rest of the instrumentation herself. Khan said in an interview with The Sun newspaper that "Daniel" is based on a fictional character that she fell in love with as a teenager. The single's cover features Khan with an image of the character Daniel LaRusso, from the film The Karate Kid, painted on her back. A character much like LaRusso also features at the end of the music video which goes with the song. The B-side of the 7" is a cover version of a 1980 single by The Cure.
