Diamonds in the Sky

Diamonds in the Sky is a collection of astronomy-based science fiction stories edited by Mike Brotherton and funded under his National Science Foundation grant AST 05-07781. The purpose of the anthology is to provide stories with ample and accurate astronomy spanning a range of topics covered in introductory courses. Instructors in high school and college may find these stories useful, as some students may learn concepts more easily through story than from lecture. Fans of science fiction with good science should also enjoy these stories. Contributions include both original stories and reprints from some of the top science fiction writers working today. Special thanks to Jeremy Tolbert, Scott Humphries, and Nicole Wade for their efforts.

To Kill a Mockingbird

The unforgettable novel of a childhood in a sleepy Southern town and the crisis of conscience that rocked it, To Kill A Mockingbird became both an instant bestseller and a critical success when it was first published in 1960. It went on to win the Pulitzer Prize in 1961 and was later made into an Academy Award-winning film, also a classic.

Rock Metamorphosis by Kinetic Energy (October, 2019)

The objective of this work was to test the hypothesis that weathering-resistant surface layers found in intensively hammered petroglyphs at many sites worldwide and on other heavily battered metamorphosed rocks are the result of kinetic energy-induced tribological reactions. The methods of material testing included extensive fieldwork and in-situ studies at an Indian site that had been subjected to fluvial battery in the distant geological past; the removal of numerous surface and subsurface samples; and their analysis by several laboratory methods. These included binocular light microscopy, scanning electron microscopy, thin sectioning and elemental composition determination of crucial sites. It was confirmed that samples show evidence of crystallization by ductility of formerly amorphous silica cement in quartzite, yielding a tectonite of fully crystalline quartz. This finding confirms that the surficial application of very high levels of kinetic energy to certain rock types that are susceptible to metamorphosis can yield exceptionally weathering-resistant surface layers. This phenomenon has not been described before. Although it was first observed in rock art it is now thought to occur much more widely in numerous geological contexts, such as at fault mirrors, in the form of what has been regarded as glacial polish and on ventifacts.

Star Dragon

The SS Cygni probe sent back hours of video, captured by the Biolathe AI, but only a few minutes mattered-the four minutes that showed a creature made of fire, living , moving, dancing in the plasma fire of the double star's accretion disk. A dragon made of star stuff, so alien that only a human expedition to observe and perhaps capture it, could truly understand it. It's a perilous journey into the future, however, for SS Cygni is 245 light-years from Earth, and even though only two years subjective time will pass on board the Karamojo, the crew will return to an Earth where five hundred years have passed.

Les Trois Yeux De La Connaissance

Ce livre traite d'une quête du savoir globale ou « complète » — quête visant non pas à quelque fi-nalité en matière de savoir, mais plutôt à un certain équilibre au sein de la quête elle-même. Il y sera question de science empirique, de philosophie, de psychologie et de religion transcendantale; de connaissance sensorielle, de connaissance symbolique, et de connaissance spirituelle; et nous nous efforcerons de voir comment toutes ces disciplines s'agencent de façon harmonieuse.

The Advance of Science in the Last Half-Century

t instigated by love of knowledge] In fact, the history of physical science teaches (and we cannot too carefully take the lesson to heart) that the practical advantages, attainable through its agency, never have been, and never will be, sufficiently attractive to men inspired by the inborn genius of the interpreter of nature, to give them courage to undergo the toils and make the sacrifices which that calling requires from its votaries. That which stirs their pulses is the love of knowledge and the joy of the discovery of the causes of things sung by the old poets--the supreme delight of extending the realm of law and order ever farther towards the unattainable goals of the infinitely great and the infinitely small, between which our little race of life is run. In the course of this work,

Religion et psychologie individuelle comparée

La médecine du XIXe siècle, uniquement préoccupée par la lésion anatomique et le trouble fonctionnel, ignorait l'âme et, de ce fait, abandonnait en grande partie à la religion le domaine psychique. Avec les découvertes de Freud et d'Adler, la naissance de la psychologie profonde créa, dès le début de XXe siècle, une nouvelle conception des choses. L'intégration dans les recherches de la psychopathologie d'une fonction psychique, de ses lois et de ses perturbations posait le croyant avec son orientation métaphysique, religieuse et le médecin de formation scientifique en face d'un problème dont les multiples aspects n'échappaient ni au psychothérapeute, ni au directeur de conscience. Une délimitation très précise de leur champ d'action était devenue nécessaire sur le plan pratique, une définition de leur optique s'avérait indispensable au point de vue théorique.
