ABSTRACT
In June 1905 Einstein submitted his famous paper on what is now called Special Relativity. Electricity and magnetism, motion and rest, gravity and acceleration were all unified by Einstein in this way. It therefore restricts both computational and informational capabilities and introduces exactly the same synchronisation problems as can be found with time and space in real world relativistic problems. It is easy to glibly pronounce information and computation as being relative concepts, but it does not necessarily follow that they should therefore obey any of laws of relativity. If the physical theories of quantum mechanics are indeed correct and the quantum mechanical version of the Church Turing model is indeed valid, then the term context' in the above equation is especially relevant. The speed of light is not only an unbeatable absolute but it is also of principal concern in all synthetic computations.
