Robert Dicke (1961) later hit on an interesting rejoinder. As noted, Dirac had taken it to be more than mere coincidence that the Hubble age should happen to have the value A, thus linking it to the other two cosmic features. Dicke showed that this was indeed not a coincidence, but his explanation was quite different from Dirac s. Observers can exist in the universe only after heavy elements have had time to form, and within the maximum lifetime of a massive star. Calculations show that, given the components from which the other two constants are constructed, the Hubble age during the epoch of man, as Dicke called it, would necessarily be of the order of A. The relationship between H and the other two does not therefore indicate an invariant relationship, as Dirac thought, but is a selection effect, a constraint set on the value of Tby the conditions of human observership. Ihere is no reason, then, to make the gravitational constant or the mass of the universe vary.

Brans-Dicke theory A modification of the general theory of relativity that combined tensor and scalar qualities and allowed the gravitational constant Gto vary with time in a way that is in accord with Mach s principle. The Brans-Dicke theory was proposed by the American physicists Carl Brans (1935- ) and Robert Dicke (1916-97) inl961.Thistypeoftheoryhas largely been abandonded since its predictions have not been supported by accurate ejqierimental tests of the general theory of relativity.

In a consideration of the people involved in this initial effort, too many names come to mind to list all of them, for fear of leaving some out. When the subcommittee was formed, four subsections were set up. In addition to section leaders and the subcommittee chairperson, a subcommittee secretary was appointed. Those taking on these initial leadership positions were Tudy Raumann (Monsanto), subcommittee chair Paul Mdler, subcommittee secretary (US Army Corps of Engineers) John Ball (University of Alabama), followed by L. David Suits (then of the New York State DOT), Section on Permeability and PUtration chair Dana Toups (Carthage MUls), followed by Robert G. Carroll, Jr. (then of CEMC-Mirafi), Section on Endurance Properties chair Dick Van Scoy (DuPont), followed by Bennett Baird (DuPont) shortly after its formation. Section on Mechanical Properties chair and Marshall Silver (University of Illinois and STS Consultants), followed by Barry Christopher (then of STS Consultants), Section on Nomenclature chair.
