Grimmett: The Random-Cluster Model

Zitat

Veröffentlicht am von

“The random-cluster model as studied so far is random in space but not in time. There are a variety of ways of introducing time-dynamics into the model, and some good reasons for so doing. The principal reason is that, in our 3 + 1 dimensional universe, the time-evolution of processes is fundamental. It entails the concepts of equilibrium and convergence, of metastability, and of chaos. A rigorous theory of time-evolution in statistical mechanics is one of the major achievements of modern probability theory with which the names Dobrushin, Spitzer, and Liggett are easily associated.” (p. 222) #Grimmett #Random-ClusterModel #Space #Time #ProbabilityTheory

“Primary times provide the grounds for secondary times. Primary times are relational. Secondary times are processual. Primary times are spatial, yet saturated with a ceaseless, liquid motion. Secondary times separate space and time.” (p. 156) #Olsen #Shanks #Webmoor #Witmore #time #space

Dewar: Spacetime

Zitat

Veröffentlicht am von

„The key difference from Newtonian spacetime, then, is that there is no ‘persistence of space over time’: since there is no notion of a vector being ‘purely temporal’, we cannot say of two points in G0 that they differ by a purely temporal vector, and hence correspond to the same point of space at two different times. (By contrast, since we do have a notion of purely spatial vectors, we can say of two points of G0 that they differ by such a vector and hence correspond to two different points of space at the same time; this is precisely the relation that foliates G0.).“ (p. 55) #Dewar #spacetime

„A physics of mathematical communication challenges philosophy to welcome the concept of ‚mass‘ as a third in the fundamental order of physics, next to those of space and time.“ (p. 5) #Bühlmann #communication #mass #space #time

Mill: Number and Space

Zitat

Veröffentlicht am von

„In the laws of number, then, and in those of space, we recognize in the most unqualified manner, the rigorous universality of which we are in quest. Those laws have been in all ages the type of certainty, the standard of comparison for all inferior degrees of evidence. Their invariability is so perfect, that it renders us unable even to conceive any exception to them; and philosophers have been led, though (as I have endeavored to show) erroneously, to consider their evidence as lying not in experience, but in the original constitution of the intellect.“ (Chap. V, § 1) #Mill #number #space
