From the Arrow of Time to the Arrow of Life
Earth, Moon, and Planets, 2006Astrobiology, like many (but not all) sciences, must take into account questions of the “Why?”, “Where?”, “How?” and “When?” type. In this introductory chapter, we explain why, in this book, we will only consider two of these questions that are, moreover, deeply interrelated. Chronology is by definition related to the “when?” question but as soon as we

The Review of Economic Studies, 1975
In a famous article [1], Arrow studied the allocation of risk-bearing in a competitive economy consisting of I individuals, C commodities and S states. Two schemes were considered. The first scheme was one equipped with S x C complete contingent commodity claims. These claims were assumed to be tradable in the market.

American Journal of Physics, 1962
The time symmetry of the physical laws is discussed. The asymmetry in all statistical processes is found to be related to the tendency for radiation to diverge and that in turn is related to the expansion of the universe. No asymmetry is contained in the laws of electrodynamics, and the choice of the retarded potentials is not a time unsymmetrical step.

Kenneth Arrow’s “impossibility” theorem is rightly considered to be a landmark result in economic theory. It is a far-reaching result with implications not just for economics but for political science, philosophy, and many other fields. It has inspired an enormous literature, “social choice theory,” which lies on the interface of economics, politics ...

Appalachian Heritage, 2004
There was an arrow in the light. It was a flickering shaft that danced through the golden glow of late afternoon in the far mountains, cutting a graceful arc toward a target that it never hit. It snapped past the deer and disapperared, lost in the depths of the shadows and the forest floor.

Arrow-arrow correlations for the six-vertex model
Physical Review E, 2013The six-vertex model on a square lattice is "exactly solvable" because an exact formula for the free energy can be obtained by the Bethe ansatz. However, exact formulas for the correlations of local bulk observables, such as the orientation of the arrow at a given edge, are, in general, not available.

, 1983 Space and time are the most fundamental ideas of the scientist’s picture of the world, and also of the language in which we all describe our thoughts and sensations. We use the concepts of space and time to “relate” ourselves to world phenomena that we and other people observe and to “verify” that what other people report to us as “their observations ...
