Abstract

In 2006, a final result of a measurement of the gravitational constant G performed by researchers at the University of Zuerich was published. A value of G=6.674 252(122)x 10^{-11} m^3 kg^-1 s^-2 was obtained after an experimental effort that lasted over one decade. Here, we briefly summarize the measurement and discuss the strengths and weaknesses of this approach.
