It is widely believed that the gravitational constant G is difficult to measure with any degree of precision, due to the tiny magnitude and difficulty in shielding experimental apparatuses. Most scientists also believe that G cannot be derived in terms of other more precisely known physical constants. In his book, scientist Ronald Sherrod seeks to disprove these notions. Sherrod will show, by numerical analysis, an indirect pathway for relating G to other physical constants such that it can be evaluated. Thinking outside the box, Sherrod attempts to break through those barriers scientists have put up concerning G. About the Author: Ronald Sherrod is a retired member of the scientific community. He is currently a member of the ResearchGate community of scientists and is actively working on methods of carbon entrapment in regards to climate change. Sherrod resides in San Jose, California.
