Touring machines
In considering what to ask Lewis Wolpert’s good fairy godmother of science [1], I am reminded of John von Neumann, a pioneer of computer science. In 1946 he wrote to Norbert Wiener, the father of cybernetics, bemoaning the fact that Turing, Pitts and McCulloch had shown that anything the brain can do can be mimicked by a universal neural mechanism — a Turing machine [2]. Inverting the argument,...
متن کاملTouring the Calculus Gallery
1. INTRODUCTION. The premise of this article—what our friends in theatre would call its " conceit " —is that we are about to visit a gallery devoted to the history of calculus. Admittedly no such institution exists, but it is easily imagined. One need only think of an art museum, albeit one whose masterpieces are not canvases but theorems and whose masters are not Courbet and Cezanne but Leibni...
متن کاملPeopling and early cultures of the pacific northwest.
SCIENCE Geological History In past discussions and speculations concerning the early peopling of the New World, the hypothesized "migration cor-ridor" between the Cordilleran and Lau-rentian ice sheets has figured prominently (1). By contrast with this much-mooted route east of the Rocky Mountains , little consideration has been given to possible routes west of the Rockies. I will examine such ...
متن کاملTouring Convex Bodies - A Conic Programming Solution
We study the problem of finding a shortest tour visiting a given sequence of convex bodies in R. To our knowledge, this is the first attempt to attack the problem in its full generality: we investigate high-dimensional cases (d ≥ 2); we consider convex bodies bounded by (hyper)planes and/or (hyper)spheres; we do not restrict the start and the goal positions of the tour to be single points, we m...
متن کاملNarrative Construction of Authenticity in Pilgrimage Touring
This paper analyses the shift from constructivist to existentialist conceptions of authenticity in tourism. I argue that the existentialist approach represents a withdrawal from an ongoing and unresolved debate, rather than the reconciliation that it has sometimes been presented as. Such an approach has divorced the notion of authenticity from any inherent relationship to the act of touring. Ut...
