Rereading Ludwig Boltzmann

Ludwig Boltzmann is one of the first physicists who brought probability and statistical considerations into physics. Particularly famous is his statistical explanation of the second law of thermodynamics. However, Boltzmann’s ideas on the relationship between the thermodynamical properties of macroscopic bodies and their microscopic mechanical constitution, and the role of probability in this r...

In this work we recall and discuss optimality criteria for decision making under uncertainty with respect to different assumptions concerning the structure of the information available. First, an overview of the basic concepts of classical decision theory is given. Here, particular emphasis is placed on explaining classical decision criteria (i.e. criteria for the case that the uncertainty can ...

This article summarizes the status of the Tevatron Run II searches for lepto-quarks in p¯ p collisions at √ s = 1.96 TeV. The analyses discussed use datasets with integrated luminosities ranging from 72 pb −1 to 200 pb −1 .

The Conics of Ludwig Kiepert:

If a visitor from Mars desired to leam the geometry of the triangle but could stay in the earth' s relatively dense atmosphere only long enough for a single lesson, earthling mathematicians would, no doubt, be hard-pressed to meet this request. In this paper, we believe that we have an optimum solution to the problem. The Kiepert conics, though seemingly unknown today, constitute a significant ...
