PetaMem Logo Description
The PetaMem Logo is a stylized Turing Machine containing lots of
metainformation or - if you prefer that nomenclature - symbolism:
The Turing Machine
A Turing machine is a very simple machine, but, logically speaking,
has all the power of any digital computer. It may be described as
follows: A Turing machine processes an infinite tape. This tape is
divided into elements, any element of which may contain a symbol
from a finite alphabet, with the restriction that there can be only
finitely many non-blank elements on the tape. At any time, the
Turing machine has a read/write head positioned at some element on
the tape.
Alan Turing argued that his formalism was sufficiently general to
encompass anything that a human being could do when carrying out
a definite method.
The "Tape"
The black circles in the logo represent the "tape elements" of such
a Turing machine. Here, however, they represent more than that. They are
the "Memes" - the mind units - our systems are working with. The blue
triangle is the read/write head that is working with these Memes. The
tape itself is infinite showing the "enormous amount" of mind units
the system has to handle. It also is not simply linear but a
projection of a helix which should symbolize the analogy between
Memes and Genes.
