P. Hardie and R. K. Gaye Table of Contents Book II Part 1 Of things that exist, some exist by nature, some from other causes. 'By nature' the animals and their parts exist, and the plants and the simple bodies (earth, fire, air, water)-for we say that these and the like exist 'by nature'. All the things mentioned present a feature in which they differ from things which are not constituted by nature. Each of them has within itself a principle of motion and of stationariness (in respect of place, or of growth and decrease, or by way of alteration). On the other hand, a bed and a coat and anything else of that sort, qua receiving these designations i.e. in so far as they are products of art-have no innate impulse to change. But in so far as they happen to be composed of stone or of earth or of a mixture of the two, they do have such an impulse, and just to that extent

Spinors in Geometry and Physics Math 425 and Physics 498C S.B. Bradlow and R.G. Leigh Table Of Contents: Course Abstract How to find us How to find the classroom Full Syllabus ... Announcements Course Abstract Spinors have played a crucial role in both the physics and the mathematics of the 20th century. Discovered in 1913 by Cartan in his investigations of the representation theory of the orthogonal groups, spinors first appeared in physics in the 1920's in the guise of Pauli's spin matrices and in Dirac's relativistic theory of electron spin. Since that time, spinors, spin structures and their attendant Dirac operators have remained of fundamental importance in quantum physics and in many areas of mathematics, especially those dealing with the relation between geometry, topology and analysis. In mathematics they provide key insights into many questions, including index theorems for elliptic operators, the integrality of characteristic numbers, existence of metrics of positive scalar curvature, twistor spaces, and (most recently) Seiberg-Witten theory. The goal of this course is to survey the role of spinors in mathematics and physics with emphasis on topics of modern importance. We will emphasize the interaction between the physical and mathematical points of view. Topics to be covered include:

93. What Does Negative Temperature Mean? A short article from USENET physics FAQ. http://math.ucr.edu/home/baez/physics/ParticleAndNuclear/neg_temperature.html

[Physics FAQ] Updated 1993 by SIC. Original by Scott I. Chase. Below Absolute Zero - What Does Negative Temperature Mean? Questions: What is negative temperature? Can you really make a system which has a temperature below absolute zero? Can you even give any useful meaning to the expression 'negative absolute temperature'? Answer: Absolutely. :-) Under certain conditions, a closed system can be described by a negative temperature, and, surprisingly, be hotter than the same system at any positive temperature. This article describes how it all works. Step I: What is "Temperature"? To get things started, we need a clear definition of "temperature." Actually various kinds of "temperature" appear in the literature of physics (e.g., kinetic temperature, color temperature). The relevant one here is the one from thermodynamics, in some sense the most fundamental. With a total energy E, S has many possible internal states (microstates). The atoms of S3 can share the total energy in many ways. Let's say there are N different states. Each state corresponds to a particular division of the total energy in the two subsystems S1 and S2. Many microstates can correspond to the same division, E1 in S1 and E2 in S2. A simple counting argument tells you that only one particular division of the energy, will occur with any significant probability. It's the one with the overwhelmingly largest number of microstates for the total system S3. That number, N(E1,E2) is just the product of the number of states allowed in each subsystem, N(E1,E2) = N1(E1)*N2(E2), and, since E1 + E2 = E, N(E1,E2) reaches a maximum when N1*N2 is stationary with respect to variations of E1 and E2 subject to the total energy constraint.
