Measurement Procedure
• Resonance Frequency is about 21 GHz
• Take 5 points on the resonance
• Fit for amplitude, with and mean
• Do it twice a second
• Take tilt, temperature, barometer
• Get seismic noise
• Get height of the waves in the N-Sea

Big G?
• In 8/2010 a new determination was published by Parks and Faller
• The number is - 300 ppm off the nominal
• Value, but 10 sigma from the best value
• Sofar
• SHOULD BE CLARIFIED

DM problem
• It is nown since long that stars in galaxies• And galaxies in clusters do not move
following Newton (DM-Problem),• Zwicky, and Rubin• Solution proposed by Milgrom proposes
changing Newtons law at small acceleration• Only one Parameter a(0) = 1.2x10e-10
m/sec(2)

In the future
• Get a more accurate measurementof G
• Improve on errors at small masses
• (accelerations at a(0) and below)
• It may require choosing a more quiet place
