Today all disciplines of various science fields are converging and developing. Nowadays we can even say that architecture involves and can be linked to almost any field, nevertheless it is science or fiction. It means that a contemporary architect must keep up with any advances in all possible fields of science and technology. Author underlines, that without experimenting the latest tools, we may run into self-repetition and loosing of innovativeness. Thanks to Peter Eisenmann, today we approach a project and we explain processes. He is interested in process, its purity, the capacity of this formal language to prove things, generation of meaning signification. Final result is really not important. Nowadays, with contemporary approaches meaning is same as before, only new generation of advanced architects now use 3D modeling software instead of cardboard. Now architects have the power of software and the power of NURBS. The formal system is depending in how many rules you have. Logic behind generative form is the same, based on works or understanding on Chomsky and computers, on and on back to Palladio.
