Block Transfer Computation

A Block Transfer Computation was a mathematical process used to create objects and affect spacetime in other ways by the power of mathematic formulae themselves.

Functioning
Block Transfer Computations could create or re-create any object or spacetime event, provided enough mathematical information was supplied. (TV: Logopolis) The Computations could also re-create or even duplicate people. Adric, imprisoned by the Master in a hadron web, created an entire city and its people. (TV: Castrovalva) Living creatures, like the Ceccec, could be made using Block Transfer Computation. (PROSE: The Tomorrow Windows) Artificial intelligences could be made as well. (AUDIO: Unregenerate!) Block Transfer Computation could even allow time travel, though it would require a quorum of 12 people. (AUDIO: The Boy That Time Forgot)

Computers could not do Block Transfer Computations as the calculations themselves would alter the nature of the computer; organic life forms had to do the work. The Monitor's people spoke their computations aloud for this reason. (TV: Logopolis) Though they were working on technological means to use Block Transfer Computations, the Logopolitans were destroyed before they completed it. Other civilisation that were capable of using Block Transfer Computation included the Time Lords, the Axos and the Nestene Consciousness. (PROSE: Cat's Cradle: Witch Mark)

Usage
The Logopolitans were the first to develop Block Transfer Computations. (PROSE: Cat's Cradle: Witch Mark) They used Block Transfer Computations to create a duplicate of the Pharos Project to maintain the CVEs which prevented entropy from destroying the universe. (TV: Logopolis)

The Time Lords used Block Transfer Computations to maintain the outer plasmic shell and interior configurations of TARDISes. (TV: Logopolis, PROSE: Cat's Cradle: Witch Mark) The Eighth Doctor used it to design the TARDIS' gardens. (AUDIO: Scaredy Cat) They also used Block Transfer Computations to create duplicates of the Eye of Harmony to power Gallifreyan timecraft. (PROSE: The Quantum Archangel)

The Remote were known to use Block Transfer Computations. (PROSE: Interference - Book One) The Remote receiver of the Eighth Doctor's companion Compassion also unintentionally processed the signals she received from the Doctor's TARDIS into Block Transfer Computations, resulting in Compassion mutating into a Type 102 TARDIS. (PROSE: The Shadows of Avalon)

The Mad Mind of Bophemeral used Block Transfer Computations to create an army. (PROSE: The Quantum Archangel)

The Pool used Block Transfer Computations to create defences for itself and horrific imagery. (PROSE: Deceit)

The Farrian stole Block Transfer technology during their conquests. They used it to open CVEs and raid E-Space. (AUDIO: The Invasion of E-Space)
