recording, and logging, but essentially their sensors are based upon
variations of a mass on a spring. If the force on a spring is to be measured
accurately to tell us geologically useful information about gravity, then
changes in spring length, :math:`ds`, must be measured with a precision of
1:109. Therefore, some form of "amplification" is required. A complete
changes in spring length, :math:`ds`, must be measured with a precision of :math:`10^-9`.
Therefore, some form of "amplification" is required. A complete
discussion of instruments is beyond the scope of these notes, but some of the
characteristics of the most common instruments are listed here.
