[en] Horizontal motions of a well-balanced hollow copper sphere floating and almost totally submerged in a well insulated and shielded tank filled with water at 4 deg C were measured in the vicinity of a large cliff. A motion was observed in a direction nearly perpendicular to, and directed away from, the face of the cliff. Conventional explanations for this effect have not been found. The observation is consistent with the existence of a weak, non-Newtonian, substance dependent, medium range force of a magnitude compatible with results deduced from gravity measurements as a function of depth in mines and with conclusions reached in a recent reanalysis of the Eoetvoes experiment. Further measurements with different elements and in different geometries will be required to establish definitely the existence, source, and description of such a new force

[en] Fischbach et al. infer that two objects of different elements may fall with different accelerations in the earth gravity. For the test of it, we are now constructing an experimental apparatus with a laser-interferometer to measure the acceleration-difference between two objects falling simultaneously in a vacuum chamber and we tested a release-mechanism which is an important part of the apparatus

[en] A mechanical measuring method is presented for inexpensive measuring of internal stresses. The accuracy of the method is assessed by considering a number of errors and is checked by means of comparative measurements. The distributions of internal stresses in depth determined so far are physically plausible. (orig./HP)

Zur kostenguenstigen Messung von Eigenspannungen wird ein mechanisches Messverfahren vorgestellt. Die Verfahrensgenauigkeit wird aufgrund einer Fehlerbetrachtung abgeschaetzt und mit Hilfe von vergleichenden Messungen ueberprueft. Die bisher ermittelten Eigenspannungs-Tiefenverteilungen sind physikalisch plausibel. (orig./HP)Journal
[en] Interaction-free measurements introduced by Elitzur and Vaidman (1993) allow finding infinitely fragile objects without destroying them. Paradoxical features of these and related measurements are discussed. The resolution of the paradoxes in the framework of the Many-Worlds Interpretation is proposed. (orig.)
