Preface Ian Stevenson is a man extraordinary in his intellectual and scientific accomplishments and even more extraordinary in his possession of a quality of mind which resists and never allows itself to be dominated by assumption. And so, against a powerful scientific ethos, which generally looks askance upon matters such as religions and more specifically(More)
This chapter focuses on digital technologies and geometry education, a combination of topics that provides a suitable avenue for analysing closely the issues and challenges involved in designing and utilizing digital technologies for learning mathematics. In revealing these issues and challenges, the chapter examines the design of digital technologies and(More)
Transcendental near-death experiences show some cross-cultural variation that suggests they may be influenced by societal beliefs. The prevailing Western model of near-death experiences was defined by Moody's description of the phenomenon in 1975. To explore the influence of this cultural model, we compared near-death experience accounts collected before(More)
Good performance of optical coatings depends on the appropriate combination of optical and mechanical properties. Therefore, successful applications require good understanding of the relationship between optical microstructural and mechanical characteristics and film stability. In addition, there is a lack of standard mechanical tests that allow one to(More)
Mechanical elasticity of hexagonal wurtzite GaN nanowires with hexagonal cross sections grown through a vapour-liquid-solid (VLS) method was investigated using a three-point bending method with a digital-pulsed force mode (DPFM) atomic force microscope (AFM). In a diameter range of 57-135 nm, bending deflection and effective stiffness, or spring constant,(More)
—The principal features of two series of cases suggestive of reincarnation in Lebanon were compared. The series were investigated about a generation apart by two different investigators. In three important features, the two series were closely similar; in other features they were not similar, probably because of differences in the thoroughness of(More)
