Science, the 3D printer as a global manufacturer
An Oxford researcher studied Rome, June 28 (askanews) – “The 3D printer as a global manufacturer, capable of reproducing any object, even itself”. This came from a lecture by Chiara Marlito, a theoretical physics researcher at Wolfson College at the University of Oxford, to Side Academy students. “The global manufacturer is an idea born of the extremely creative mind of mathematician and physicist John von Neumann,” explains the scientist to the boys at the Veronese Graphic Academy. In the 1950s he created this kind of ideal machine for simulating the properties of living things, because he realized that by observing a cell that reproduces only, it is allowed to reproduce itself physically. “Self-replication occurs daily in organisms, but is not permitted under a Turing machine for the general computer.” “Then he invented the universal manufacturer. It is called a constructor because you want to make a computer paradox, so it is an object that not only does arithmetic but can make general conversions, given raw materials and a program that describes what you want to create. The universal manufacturer does. Executes the instructions of this program step by step and constructs the desired object. He must also be able to make a copy of himself, being himself a potential object. The 3D printer was considered by John von Neumann to be a multifunctional 3D printer that could also make a copy of itself if needed. It is therefore legitimate to ask at this point what the limits of such a machine are, that is, what things can be made. “The universal manufacturer is a very simple idea but it is also very powerful. “We can imagine, given the laws of physics, that the global manufacturer is not in a position to create a particle accelerator that would make them travel faster than the speed of light,” explains Chiara Marlito.
