AbstractAbstract
[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

AbstractAbstract
[en] After reviewing the reasons of the existence of a new long range force in Nature, the limits that may be placed upon this new long-range force which couples to mass are presented. Some positive evidence that it exists are presented (measurements of 6N, gravity gradient anomaly)

AbstractAbstract
[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

AbstractAbstract
[en] The gaugeless limit helps to clarify and expose the heart of the problems confronting the standard-model. The existence of a residual force not proportional to gauge couplings manifests itself very clearly, and it is difficult to avoid facing its reality. Whether this is a fifth force is an arguable matter of semantics. If the weak force is what is mediated by W and Z, then the 5th force may be as yet undiscovered. However, we must still conclude that the W-exchange force is not ''pure gauge'', it is nonvanishing in the gaugeless limit. What is to be done if the phenomenological formulae for the W masses and for the partial width into electron and its neutrino are renounced. That is all that is needed to infer electron instability in the gaugeless limit. This is not to say that there are no alternatives possible, only that alternatives require a serious change or extension of the conventional point of view. What might such alternatives be. Perhaps in some extended theory (e.g. GUT) the gauge couplings are themselves functions of some parameter, call it λ, which has the property that α → 0 as λ → 0. It may be that some of the remaining standard-model parameters (e.g. quark and lepton masses) also vanish as λ → 0; this would then protect electron stability. This state of affairs might occur because the Yukawa couplings of fermions to the Nambu-Goldstone bosons W vector vanish as λ → 0 or even that GF → ∞ as λ → 0. And if superstring theory fulfills the promises of its prophets, then it may be arguable that the α's are not parameters at all and cannot be varied, since the theory contains no free dimensionless parameters

AbstractAbstract
[en] All science - physics in particular - is concerned with discovering WHY things happen as they do. The WHYS so adduced must clearly be ''deeper'', more universal, more axiomatic, less susceptible to direct experimental testing, than the immediate phenomena to be explained. The WHYS of one generation are often the points of departure for the next, to whom the earlier WHYS can appear subjective, conditioned by ''unscientific'' thinking, even wrong. The glory of science is that, this notwithstanding, correct predictions are often made - at least to the extent of the experimental accuracies achievable and often better. This continuing, ever-sharpening process about the WHYS of physics is discussed in the context of the fundamental unification of physical forces on which the present generation is engaged
