Abstract The Game of Life cellular automaton is a classic example of a massively parallel collision-based computing device. The automaton exhibits mobile patterns, gliders, and generators of the mobile patterns, glider guns, in its evolution. We show how to construct basic logical operations, AND, OR, NOT in space-time configurations of the cellular automaton. Also, decomposition of complicated Boolean functions is discussed. Also in this paper advantages of our technique are demonstrated on an example of a method for text encryption by mapping text to binary space. This method is based on glider and rules of Game of Life.
textbooks in the world and used at princeton and yale and a lot of the top universities so i don t think what we teach at harvard is anything different than you d find in many other major universities throughout the world. ok, for the 50, 60, 70 kids who walked out, are they going to be penalized for missing that class? no, they won t be penalized but they missed some material that might be on the next exam. they ll have to catch up from some of their colleagues and get the lecture notes from friends. i think, professor, this could be the first time that we ve heard about college students actually doing a mini revolt, a walkout during class to align themselves with the occupy, in your case, boston movement. yeah, as far as i know, it is. you know, in some ways, i have some respect for the students. i don t agree with their political point of view or what they re saying about my class but the fact that they want to engage broadly in the public debate of what s going on with the
