Technocyte: A nanoscale artificial device (especially a nanite) in the human bloodstream used for repairs, cancer protection, as an artificial immune system or for other uses. [AS 1995]

 

Terraform: To change the properties of a planet to make it more earth like, making it possible for humans or other terrestrial organisms to live unaided on it, for example by changing atmospheric composition, pressure, temperature or the climate and introducing a self-sustaining ecosystem. This will most probably be a very long-term project, probably requiring self-replicating technology and megascale engineering. So far Venus and especially Mars look the most promising candidates for terraforming in the solar system. [Jack Williamson1938] [AS] Speculation exists that with the advent of mature MNT that we should be able to accomplish Terraforming a planet such as Mars in years, rather than decades [editor]

 

Thermal Noise: the vibration and motion of atoms and molecules caused by the fact that they have a temperature above absolute zero. [RCM] Once used as an argument on why MNT could not work. Since refuted: See That is impossible! How good scientists reach bad conclusions

 

Top Down Moulding: [AKA: mechanical nanotechnology] Carving and fabricating small materials and components by using larger objects such as our hands, tools and lasers, respectively. [NTN] Opposite of Bottom Up.

 

Transhuman: someone actively preparing for becoming posthuman. Someone who is informed enough to see radical future possibilities and plans ahead for them, and who takes every current option for self-enhancement. [Term: FM-2030 Def.:Max More]

 

Transhumanism: Philosophies of life (such as Extropianism) that seek the continuation and acceleration of the evolution of intelligent life beyond its currently human form and human limitations by means of science and technology, guided by life-promoting values. [Max More 1990]

 

Transistor: the basic element in an integrated circuit. An on/off switch (consisting of three layers of a semiconductor material) that consists of a source (where electrons come from), a drain (where they go) and a gate that controls the flow of electrons through a channel that connects the source and the drain. There are two kinds of transistor, the bipolar transistor (also called the junction transistor), and the field effect transistor (FET).

 

Tribology: study of friction, wear and lubrication of interacting surfaces. [BNL]

 

Tubeologist: Someone who knows their nanotubes inside and out, such as David Tom·nek [uhf]

 

Turing Test: Turing's proposed test for whether a machine is conscious (or intelligent, or aware): we communicate via text with it and with a hidden human. If we can't tell which of our partners in dialogue is the human, we say the computer is conscious. [AS]
