Re: [Phys-L] What is the best value and uncertainty to assign to G?

Perhaps not a canonical example of how Science Is Done, but a fascinating account
of experimental approaches to refining the value of a fundamental constant.

Thanks to Aanti for noticing it.

we have had a discussion on gravitational constant in the past ("New gravitational constant", starting from 22 Jan 2008). However, there is an interesting article in Physics Today on the quest for a better value of G: <>

Among other things, they write that "it appears that we know G to only three significant figures". Astonishing!
