Comments on “Frontier experiments: Tough science- Five experiments as hard as finding the Higgs”

The five frontier experiments published in Nature are commented item by item: spotting distant signs of life, seeing through the molecular mirror, looking for extra dimensions, catching a gravity wave, redefining the kilogram. It is concluded that the first two experiments are great ideals that are impossible to realize in recent years, the last three are false theories pulling physics into morass. Key words:...

The law of universal attraction with momentum exchange between objects and microparticles

The law of universal attraction has been used widely. However, how two objects attract each other is still a riddle. Hypotheses, such as gravitons, universal repulsion, sub-photon seas, etc., all have flaws, and do not deal with the basic reason why there is such a law. In this paper, suppose: (1) microparticles at a certain speed, moving like thermal motion of molecules, are distributed in space; (2) the objects are...

The modified simple equation method and its applications to (2+1)-dimensional systems of nonlinear evolution equations

The modified simple equation method is employed to find the exact traveling wave solutions involving parameters for nonlinear systems of evolution equations via the (2+1)-dimensional Konopelchneko-Dubrovsky equations and the (2+1)-dimensional Nizhnik-Novikov-Vesselov equations in two dimensions. When these parameters are taken to be special values, the solitary wave solutions are derived from the exact traveling wave...

Land use land cover change detection of Patani micro-watershed of Madhya Pradesh using remote sensing data

This study investigates Patani micro-watershed situated in Majhagawan block of Satna District (M.P.). The watershed characterization was carried out using RS and GIS techniques. The major aim of this study is to prepare land use land cover and their change detections. In this study IRS-P6 Sensor, LISS-III satellite images of the dates 19th October, 2008 and 5th January, 2008 were used to detect the seasonal (Kharif and...

Radio-sensitivity of selected cowpea (Vigna unguiculata) genotypes to varying gamma irradiation doses

An appropriate dose of radiation should be established on target genotypes before large scale mutagenesis undertaken. The objective of this study was to determine an ideal dose of gamma radiation to induce genetic variation in selected cowpea (Vigna unguiculata) genotypes. Seeds of three Namibian released cowpea genotypes were gamma irradiated using seven dozes at the International Atomic Energy Agency, Austria....
