Michael Polanyi (1891-1976) marks a turn in human perspective parallel to and as significant as the turn from the Ptolemaic to the Copernican angle of vision. The Ptolemaic way of viewing the world is named after Claudius Ptolemy, one of the great geographers and astronomers of the Graeco-Roman period, who was active in Alexandria, Egypt, in the Second Century of the Christian Era. In Ptolemy’s...

Acute myocardial infarction (AMI) is a social burden. However, being able to predict AMI could lead to prevention. A previous study showed only the relation between the lunar phase and the occurrence of AMI, but the period it takes for the moon to orbit around the earth and the period of the lunar phase differ. This study investigated the effect of the gravitation of the moon on AMI. Data was c...

To be able to simulate P-wave propagation in a heterogeneous spherical Earth, we solve the acoustic wave equation in spherical coordinates numerically for axi-symmetric media. We employ a high-order nite-diierence scheme which allows us to simulate arbitrary heterogeneous structures with wavelengths as small as 10km. A standard regular gridding in spherical coordinates leads to a continuously d...
