摘要: The Newtonian gravitational constant G was the first known fundamental of physics. Nevertheless, measurement its value still seem to be in a rather sad shape. Recently, CODATA Task Group on Fundamental Constants recommended preliminary with relative uncertainty 0.15 %. This is more than ten times larger as previous recommendation!
