Experimental Discovery of the Particle Properties of Gravity and Gravitons by Theoretical Investigation of the Bent Point of Space Time

As, it is known having more challenged on the wave or particle nature of light, from the theory of Newton to proof of its being wave by Huygens and also Young’s Double-slit experiment, more important ,Maxwell equations, all showed the nature of being wave of the light till Heinrich Hertz discovered photoelectric phenomenon and after that Einstein talked about the mathematic and quantum characteristics of this phenomenon, his explanations about this phenomenon showed failure of the characteristic of being wave of light in photoelectric explanation so double wave- particle characteristic failed in the scientific society. We all know that many of mass and energy fundamental systems have the same double characteristic of the light. The Photoelectric is the action of light and matter interactions that can prove the double light- particle nature because of inability of being wave principals of the light. Another one of the nature fundamental forces which many believed on its double wave- particle nature is gravity. In this essay we try to interpret the inability of wave nature of gravity in explanation of dark matter and we will see how the concept of invisible masses of the matter is the only action of the graviton interaction and proof of existence of constituent packs of gravity energy i.e. gravitons. Discovering this innovation is wonderful.

Experimental study of the transient motion of floats reproducing floating wood in rivers

The flow of large wood among hydraulic structures in rivers, especially in urban areas, can cause many problems. Despite many statistical, morphological and hydrodynamical studies on this phenomenon, little information is available on the transient motion of floating wood pieces. In this study, we investigate theoretically and experimentally the transient motion of floating particles under a simple acceleration. From a standard advection model we identify a particle characteristic response distance to the flow, noted λ. This key parameter is then measured for different floating particles reproducing wood in rivers (logs without and with idealized roots). We show here the typical value of this parameter as a function of particle streamwise body length for different particle geometries. The influence of roots can be well captured by an equivalent frontal area, regardless of the root pattern. This response distance could provide useful information on the probability of impact on hydraulic structures depending on the floating wood characteristics.
