A Simple Model’s Best Hope: A Brief Introduction to Universality
نویسنده
چکیده
For certain classes of systems operating at a critical point, the concept of universality can offer a way out of the reductive dilemma of modeling systems with many interacting parts. In these cases, simple models can be used to classify the large scale behavior of an entire universality class. This paper provides a brief introduction to the idea of universality and the renormalization group ideas used to derive it, along with a derivation of the power law behavior of certain observables.

Twenty five years after KLS: A celebration of non-equilibrium statistical mechanics
When Lenz proposed a simple model for phase transitions in magnetism, he couldn’t have imagined that the “Ising model” was to become a jewel in field of equilibrium statistical mechanics. Its role spans the spectrum, from a good pedagogical example to a universality class in critical phenomena. A quarter century ago, Katz, Lebowitz and Spohn found a similar treasure. By introducing a seemingly ...

Objectives: Choice theory is rooted in psychological concepts like self-concept, successful identity, and quality of the world. This theory could be useful for people seeking for hope and a better life. The purpose of this research was to investigate the effectiveness of group training of choice theory on life quality and hope in blind people. Methods: The statistical population of this ...
متن کاملAspects of Analytic Number Theory: The Universality of the Riemann Zeta-Function
Abstract. These notes deal with Voronin’s universality theorem which states, roughly speaking, that any non-vanishing analytic function can be uniformly approximated by certain shifts of the Riemann zeta-function. We start with a brief introduction to the classical theory of the zeta-function. Then we give a self-contained proof of the universality theorem. We conclude with several interesting ...
متن کاملIntrinsically Universal Cellular Automata
This talk advocates intrinsic universality as a notion to identify simple cellular automata with complex computational behavior. After an historical introduction and proper definitions of intrinsic universality, which is discussed with respect to Turing and circuit universality, we discuss construction methods for small intrinsically universal cellular automata before discussing techniques for ...
متن کاملInvestigation the effect of group hope therapy on quality of life in elderly
Introduction: Given the decline in hope during period, one possible strategy for improving the quality of life in this period is hope therapy. Therefore, this study was designed to investigate the effect of group hope therapy on quality of life. Methods: A clinical trial study was performed on 56 elderly patients. Samples were randomly divided into two groups; control and intervention. The expe...
