| This collection grew from Chief Astronomer Dr. Otto Klotz's personal collection to include the fields of geodesy, geomagnetism and seismology. |
| One of his most important contributions to the study of geomagnetism is his theory of the geomagnetic dynamo, based on convective motion within Earth's core. |
| The subject matter includes geochemistry, geochronology, geomorphology, geodynamics, geomagnetism, mineral resources, mineralogy, paleontology, petrology, planetology, seismology, solid earth geophysics and tectonics. |
| The relationship between ESP scores and personality factors, geomagnetism, local sidereal time, sender-receiver pairings, and target type was also examined. |
| One wonders if the same will happen to other lines of research, such as attempts to replicate, extend, and understand the correlations between ESP and geomagnetism. |
| Two physical variables that have been linked to free-response ESP scores, geomagnetism and local sidereal time, are additionally examined. |
