Condensation

Condensation is the change of the physical state of matter from gas phase into liquid phase, and is the reverse of evaporation. The word most often refers to the water cycle. It can also be defined as the change in the state of water vapour to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within the atmosphere. When the transition happens from the gaseous phase into the solid phase directly, the change is called deposition.

Initiation

Condensation is initiated by the formation of atomic/molecular clusters of that species within its gaseous volume—like rain drop or snow flake formation within clouds—or at the contact between such gaseous phase and a liquid or solid surface.

Reversibility scenarios

A few distinct reversibility scenarios emerge here with respect to the nature of the surface.

Bill Nye

William Sanford "Bill" Nye (born November 27, 1955), popularly known as Bill Nye the Science Guy, is an American science educator, comedian, television presenter, actor, writer, scientist, and former mechanical engineer, best known as the host of the Disney/PBS children's science show Bill Nye the Science Guy (1993–1998) and for his many subsequent appearances in popular media as a science educator.

Early life and education

Nye was born on November 27, 1955, in Washington, D.C., to Jacqueline (née Jenkins; 1921–2000), a codebreaker during World War II, and Edwin Darby "Ned" Nye (1917–1997), also a World War II veteran, whose experience without electricity in a Japanese prisoner-of-war camp led him to become a sundial enthusiast. His maternal grandmother was French, from Dancevoir.

After attending Lafayette Elementary and Alice Deal Junior High in the city, he was accepted to the private Sidwell Friends School on a partial scholarship and graduated in 1973. He studied mechanical engineering at Cornell University (where he took an astronomy class taught by Carl Sagan) and graduated with a B.S. in mechanical engineering in 1977. Nye occasionally returns to Cornell as a guest-lecturer of introductory-level astronomy and human ecology classes.

Evelyn Evelyn

Evelyn Evelyn are a musical duo formed by Amanda Palmer (of The Dresden Dolls) and Jason Webley. According to the fictional backstory described by Palmer and Webley, the duo consists of conjoined twin sisters (aka "Eva" and "Lyn"), Evelyn and Evelyn Neville, who were discovered in 2007 by Palmer and Webley. The twins are actually portrayed by Palmer and Webley, dressed in connected garments.

Controversy

Disability-rights advocates have questioned whether Evelyn Evelyn plays into stereotypes regarding disability.

Discography

In 2007, the band released a 3-song, colored 7" vinyl record, along with a 6-track CD titled Elephant Elephant, which was released in a limited edition of 1,111 copies on Jason's label (11 records); it quickly sold out. The package also contains Amanda and Jason's story of how they met the Evelyns, as well as the process of recording the vinyl, and a sticker of the two-headed elephant, Bimba & Kimba.

A full-length album, Evelyn Evelyn was released March 30, 2010, followed by a worldwide tour.
