Possible solution of dark matter, the solution of dark energy and Gell-Mann as great theoretician

This talk discusses the formation of primordial intermediate-mass black holes, in a double-inflationary theory, of sufficient abundance possibly to provide all of the cosmological dark matter. There follows my, hopefully convincing, explanation of the dark energy problem, based on the observation that the visible universe is well approximated by a black hole. Finally, I discuss that Gell-Mann is among the five greatest theoreticians of the twentieth century.Comment: References update

A Seventeenth-Century Air History in Conversation with Antony and Cleopatra

This article works to unpack the recurrences of air-related language utilized in Shakespeare’s Antony and Cleopatra. Throughout this play, the notions of breath, wind, air, and vapor are consistently referenced, demonstrating the way in which atmospheric intangibility was a key point of exploration for contemporary scientists and philosophers. Through this analysis, it is clear that Shakespeare employs breath in three ways: the breath of (public) life, a lack of breath, and, most importantly, breath as a symbol of power and autonomy, which at times overlaps with the breath of life in ways that demonstrate contemporary conceptualizations of living beings. The relation of breath and power is shown to exist in other seventeenth-century texts, which often thought about breath and power in relation to God, spirits, and nature. Ultimately, Shakespeare treats air as transformative, wind as a whimsical means of transportation, and vapor as contagious. These ideas coincide with seventeenth-century understandings of these meteorological concepts found in complex scientific theories, natural philosophy ideas, and cultural constructions accepted by the general public

Green-function method in the theory of ultraslow electromagnetic waves in an ideal gas with Bose-Einstein condensates

We propose a microscopic approach describing the interaction of an ideal gas of hydrogenlike atoms with a weak electromagnetic field. This approach is based on the Green-function formalism and an approximate formulation of the method of second quantization for quantum many-particle systems in the presence of bound states of particles. The dependencies of the propagation velocity and damping rate of electromagnetic pulses on the microscopic characteristics of the system are studied for a gas of hydrogenlike atoms. For a Bose-Einstein condensate of alkali-metal atoms we find the conditions when the electromagnetic waves of both the optical and microwave regions are slowed. In the framework of the proposed approach, the influence of an external homogeneous and static magnetic field on the slowing phenomenon is studied.Comment: 15 pages, 6 figure

ChemMatters: Special Issue on NASA's EOS Aura Mission (Oct. 2003)

This is the third in a series of four ChemMatters issues devoted to NASA’s Earth Observing System (EOS) Aura mission and it focuses on the chemistry of the mission. ChemMatters is designed and published for teachers to use as a supplement to their first year high school chemistry course, and as a resource for other high school science teachers. Article titles are: Whose Air Is It Anyway (global circulation of the atmosphere), Alien Atmospheres (atmospheres of other planets), Clouds (how clouds form, and cloud research), Life in a Greenhouse (how the greenhouse effect works and how people study it), Chemistry in the Sunlight (about formation of the ozone we breathe), Beefing Up Atmospheric Models (how modeling helps us understand the atmosphere), and Nobel Prize Winner: Sherwood Rowland (interview). The issue also includes a challenge asking students to determine which activities on a list would be possible on a planet with no atmosphere; and an activity, Cloud in a Bottle. A 62-page teacher's guide accompanies the issue and provides additional information on articles, follow-up hands-on activities, classroom demonstrations, and additional resources.
