The Newtonian Gravitational Constant: Present Status and Directions for Future Research
The recent measurements of the absolute value of the Newtonian gravitational constant, G, are discussed and some thoughts on the direction of future work in this area are presented. Although some of the recent searches for variations in G are also mentioned, special attention is paid to one branch of that work focusing on the possibility of detecting variations in G with temperature. Past experimental searches for such an effect are reviewed.
