Eternity

Eternity in common parlance is either an infinite or an indeterminately long period of time. In classical philosophy, however, eternity is defined as what exists outside time while sempiternity is the concept that corresponds to the colloquial definition of eternity.

Eternity, or everlasting, is an important concept in many religions, where the immortality of God or the gods is said to endure eternally. Some, such as Aristotle, would say the same about the natural cosmos in regard to both past and future eternal duration, and like the eternal Platonic Forms, immutability was considered essential.

Philosophy

The metaphysics of eternity studies that which necessarily exists outside or independently of space and time. Another important question is whether "information" or Form is separable from mind and matter. Aristotle established a distinction between actual infinity and a potentially infinite count: a future span of time must be a potential infinity, because another element can always be added to a series that is inexhaustible.

Last of the Time Lords

"Last of the Time Lords" is the thirteenth and final episode of the third series of the revived British science fiction television series Doctor Who. It was broadcast on BBC One on 30 June 2007. It is the last of three episodes that form a linked narrative, following "Utopia" and "The Sound of Drums".

One year after the events of "The Sound of Drums", the Master has conquered the Earth and enslaved its population. He holds the aged Doctor prisoner, and prepares warships for a new Time Lord Empire. Now it is up to Martha Jones to carry out the Doctor's plan and save the universe.

This episode shows the departure of Freema Agyeman as Martha Jones and John Barrowman as Jack Harkness until Series Four.

Plot

A year after the appearance of the Toclafane on Earth, humanity is on the verge of extinction. After her escape from the Valiant, Martha has been travelling around the world and avoiding the Master's detection through the use of her perception filter. She has been contacting groups of people to find a special gun created by Torchwood and UNIT that can kill the Master. Martha meets Thomas Milligan, a former doctor who leads her to Professor Docherty. Together they manage to capture a Toclafane. Upon examination they discover the Toclafane are the humans from the far future who took the rocket to Utopia. They were driven insane after discovering that Utopia was a lie. The Master created the Paradox Machine to allow them to return to the past and kill their ancestors while avoiding the grandfather paradox. Martha and Thomas leave to find the last component of the gun, and Docherty provides the Master with Martha's location in exchange for information on her own son.

Ian Gillan

Ian Gillan (born 19 August 1945) is an English singer and songwriter. He originally found commercial success as the lead singer and lyricist for Deep Purple.

Initially influenced by Elvis Presley, Gillan started and fronted several local bands in the mid-sixties, and eventually joined Episode Six when their original singer left. He first found widespread commercial success after joining Deep Purple in 1969. After an almost non-stop workload, during which time he recorded six albums in four years, and problematic relationships with other band members, particularly guitarist Ritchie Blackmore, Gillan resigned from the band in June 1973, having given a lengthy notice period to their managers.

After a short time away from the music business, he resumed his music career with solo bands the Ian Gillan Band and Gillan, before a year-long stint as the vocalist for Black Sabbath. He rejoined a reformed Deep Purple in 1984, but was fired in 1989. He rejoined the band for a second time in 1992 for their twenty-fifth anniversary, and following the recruitment of guitarist Steve Morse in 1994, has helped transform the group into a regular touring outfit, which he has fronted ever since.
