I Am Satisfied With What I Have Done : Collis P. Huntington, 19th Century Entrepreneur

The Collis P. Huntington Papers in the George Arents Research Library form one of more than twenty significant collections in the area of transportation. They are equally important as a study of a colorful period in American history and particularly of an extraordinary man in the setting of that period

Human rights abuses in "democratic" Ethiopia: Government - sponsored ethnic hatred

In Ethiopia, the world is witnessing ethnicity gone awry. The division of Ethiopia into ethnic administrative regions was mandated by an EPRDF government and written into a new constitution approved by faux elections. The idea of ethnic federalism did not originate from the people nor did they approve of it in free and fair elections. In light of events in Rwanda, the Congo, and the former Yugoslavia, it is doubtful that any people willingly would subject themselves to the horrors of state-enforced ethnic warfare. In Ethiopia, the people have not been given the opportunity so to choose at the grass roots level, and until they do, ethnic federalism must be viewed as an artificial system imposed from above.&nbsp

Tether Transportation System Study

The projected traffic to geostationary earth orbit (GEO) is expected to increase over the next few decades. At the same time, the cost of delivering payloads from the Earth's surface to low earth orbit (LEO) is projected to decrease, thanks in part to the Reusable Launch Vehicle (RLV). A comparable reduction in the cost of delivering payloads from LEO to GEO is sought. The use of in-space tethers, eliminating the requirement for traditional chemical upper stages and thereby reducing the launch mass, has been identified as such an alternative. Spinning tethers are excellent kinetic energy storage devices for providing the large delta vee's required for LEO to GEO transfer. A single-stage system for transferring payloads from LEO to GEO was proposed some years ago. The study results presented here contain the first detailed analyses of this proposal, its extension to a two-stage system, and the likely implementation of the operational system

Magnetism, FeS colloids, and Origins of Life

A number of features of living systems: reversible interactions and weak bonds underlying motor-dynamics; gel-sol transitions; cellular connected fractal organization; asymmetry in interactions and organization; quantum coherent phenomena; to name some, can have a natural accounting via $physical$ interactions, which we therefore seek to incorporate by expanding the horizons of `chemistry-only' approaches to the origins of life. It is suggested that the magnetic 'face' of the minerals from the inorganic world, recognized to have played a pivotal role in initiating Life, may throw light on some of these issues. A magnetic environment in the form of rocks in the Hadean Ocean could have enabled the accretion and therefore an ordered confinement of super-paramagnetic colloids within a structured phase. A moderate H-field can help magnetic nano-particles to not only overcome thermal fluctuations but also harness them. Such controlled dynamics brings in the possibility of accessing quantum effects, which together with frustrations in magnetic ordering and hysteresis (a natural mechanism for a primitive memory) could throw light on the birth of biological information which, as Abel argues, requires a combination of order and complexity. This scenario gains strength from observations of scale-free framboidal forms of the greigite mineral, with a magnetic basis of assembly. And greigite's metabolic potential plays a key role in the mound scenario of Russell and coworkers-an expansion of which is suggested for including magnetism.Comment: 42 pages, 5 figures, to be published in A.R.
