How Can Nature Help Us Compute?
Ever since Alan Turing gave us a machine model of algorithmic computation, there have been questions about how widely it is applicable (some asked by Turing himself). Although the computer on our desk can be viewed in isolation as a Universal Turing Machine, there are many examples in nature of what looks like computation, but for which there is no well-understood model. In many areas, we have ...
متن کاملTo compute or not to compute.
Is it possible to get a sensible answer from a computer without even running a program? Yes indeed, report Hosten et al. on page 949 of this issue— and they have the experimental proof. The thread that leads thus far has its origin in the early 1990s, with the introduction of a quantum paradox known as the Elitzur–Vaidman bomb thought-experiment. They showed that by sending a photon into a simp...
متن کاملLimits to vision: can we do better than nature?
Non-invasive wavefront sensing of the human eye provides the necessary information to design corrections which minimize the monochromatic optical errors of the eye beyond simple sphere (defocus) and cylinder (astigmatism). These "ideal" corrections must move with the eye, maintaining proper alignment with the eye's optics. Viable modes of correction include contact lenses, refractive surgery an...
متن کاملdifferent methods to compute force over a cylinder by lbm
in according to the simplicity of the lattice boltzmann method’s(lbm) algorithm and its benefits, it has been used as a successful method in computational fluid dynamics in the last decades. in this paper, lbm was used to simulate the flow over a cylinder. to analyze the application of lbm in simulation curved surface, different methods to compute drag coefficient were used. these methods are: ...
متن کاملComputing like Nature
We address the framework within which Natural computation can be carried out, and conclude that a birational ecosystemic hierarchical framework would provide for computation which is closer to Nature. This presages a major philosophical change to the way Science is carried out. A consequence is that all system properties appear as intermediates between unattainable dimensional extremes, even ex...
