Ether
Ethers (/ˈiːθər/) are a class of organic compounds that contain an ether group—an oxygen atom connected to two alkyl or aryl groups—of general formula R–O–R'. These ethers can again be classified into two varieties, if the alkyl groups are the same on both sides of the oxygen atom then it is a simple or symmetrical ether. Whereas if they are different the ethers are called mixed or unsymmetrical ethers A typical example is the solvent and anesthetic diethyl ether, commonly referred to simply as "ether" (CH3-CH2-O-CH2-CH3). Ethers are common in organic chemistry and pervasive in biochemistry, as they are common linkages in carbohydrates and lignin.
Structure and bonding
Ethers feature C-O-C linkage defined by a bond angle of about 110° and C-O distances of about 140 pm. The barrier to rotation about the C-O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.
Oxygen is more electronegative than carbon, thus the hydrogens alpha to ethers are more acidic than in simple hydrocarbons. They are far less acidic than hydrogens alpha to carbonyl groups (such as in ketones or aldehydes), however.
Etymology of chemistry
In the history of science, the etymology of the word chemistry is debatable. It is agreed that the word derives from the word alchemy, which is a European one, derived from the Arabic al-kīmīā (الكيمياء). The Arabic term is derived from the Greek χημία or χημεία. However, the ultimate origin of the root word, chem, is uncertain.
According to the Oxford English Dictionary, the majority theory is that al-kīmīā is derived from χημία, which is derived from the ancient Egyptian name of Egypt (khem, khame, or khmi, meaning "black earth", contrasting with the surrounding desert.) Therefore, alchemy is the "Egyptian art". However, it is also possible that al-kīmīā derived from χημεία, meaning "cast together".
Traditionally, the science of alchemy was once considered to have sprung from great Egyptian figure named by the Greeks "Hermes Trismegistus" (the "thrice-great" Hermes, celebrated as priest, king, and scholar), who is thought to have been the founder of the art. Reputed to have lived about 1900 BC, he was highly celebrated for his wisdom and skill in the operations of nature. In 1614 Isaac Casaubon demonstrated that the works attributed to Hermes – the so-called "Hermetic corpus" – were actually written pseudonymously during the first three centuries of the Common Era.
List of The New Batman Adventures episodes
Three years after the second season of Batman: The Animated Series ended production, the show was moved (as The New Batman Adventures) from Fox to The WB channel, which was airing and producing Superman: The Animated Series. These shows were merged as part of an hour-long segment called The New Batman/Superman Adventures. The WB wanted more episodes of Batman, so 24 new episodes were produced, which featured a different format and more focus on Batman's supporting cast.
In addition to the network's demands, the producers decided to make the show match the graphic style of Superman: The Animated Series, so all the characters and objects were redesigned as more "animation friendly" with fewer lines, usually referred to by the fans and creative staff as the "revamp" (or alternately, the "new look"). A similar graphic style was used in the rest of the DCAU later on.
The DVD box set of the series is labeled Batman: The Animated Series – Volume Four (from The New Batman Adventures), most likely to establish the connection with the original series.
Chemistry (Semisonic song)
"Chemistry" is a song by the alternative rock band Semisonic. It was their first single on their 2001 album, All About Chemistry. It reached 39 on Billboard's Modern Rock Tracks and 35 on the UK Singles Chart. The song was featured in the film 40 Days and 40 Nights and in the TV series Men in Trees and Roswell.
Music video
The music video for this song was filmed in 2000 in a house in Silver Lake, California. The video was directed by Liz Friedlander. It features the journey of a small silver ball which, at one stage, passes through a Rube Goldberg machine, and includes a series of domestic disasters.

Ether (song)
"Ether" is the second track on hip hop artist Nas' 2001 album Stillmatic. The song was a response to Jay-Z's "Takeover", a diss track directed towards Nas and Mobb Deep which appears on Jay-Z's album The Blueprint, during the Jay-Z vs. Nas feud. Nas named the song Ether because "I was told a long time ago, ghosts and spirits don't like the fumes from ether, and I just wanted to affect him with my weapon and get to his soul".
Song
Jay-Z, who had surpassed Nas in commercial success since 1998, dismissed him as a has-been on the diss track "Takeover." Nas responds to Jay's claims by rapping, "I got this, locked since Nine-One (1991), I am the truest/ Name a rapper that I ain't influenced." The song contains numerous slurs directed at Jay-Z: "When these streets keep calling, heard it when I was sleep/ That this Gay-Z and Cock-A-Fella Records wanted beef", "Then you got the nerve to say that you're better than Big/ Dick-suckin' lips, why don't you let the late great veteran live", "You a dick-ridin' faggot, you love the attention/ Queens niggas run you niggas, ask Russell Simmons" and "Put it together/ I rock hos; y'all rock fellas."
Ether (Book of Mormon prophet)
According to the Book of Mormon, Ether (/ˈiː.θɜːr/) is a Jaredite prophet, one of the last surviving Jaredites, and primary author of the Book of Ether.
Etymology
According to Hugh W. Nibley, the name "Ether" (Ether 1:6), athira, means "the one who left a trace, the one who left his mark or left a record." In all Semitic languages it is the same, and it means "to leave a track, to trail somebody."
Lineage
Life
Ether's grandfather Moron, had been king of the Jaredites. Moron was overthrown and "dwelt in captivity all the remainder of his days". Ether's father, Coriantor, was born while his father was captive and Coriantor "dwelt in captivity all his days". Ether "was a prophet of the Lord" and "lived in the days of Coriantumr; and Coriantumr was king over all the land". The people rejected his teachings concerning a "New Jerusalem", causing him to hide in a cave, where he witnessed the destruction of the Jaredites. Ether was compelled to preach to Coriantumr, who also rejected his word. After sealing up the records, Ether's final words were, "Whether the Lord will that I be translated, or that I suffer the will of the Lord in the flesh, it mattereth not, if it so be that I am saved in the kingdom of God. Amen."
Ether (Fischer-Z album)
Ether was an experimental music project by John Watts, released under the name Fischer-Z. After releasing two successful solo albums and one album of remixes, since the last Fischer-Z album, Stream, John Watts had started to take an interest in creating big beat music. After creating a whole big beat style album in 1999 entitled Bigbeatpoetry, Watts carried on in a similar style for Ether. He recorded a number of songs, featuring only his guitar and voice, and then put them over cut-up beats as a rhythm track. Watts had also added a filmic touch to the project, he travelled throughout Europe and post-9/11 New York City to find musicians at random and record them using his laptop, in their homes and on the street. Sarah Vermeersch filmed & edited the process into a road movie. "Ether" was further released as a John Watts solo album (see: Ether Music & Film), including the road movie DVD and a CD of tracks from the "Ether" album that appeared in the movie.
