Gravimetry (Part 1)

Ever experienced to stumble and tumble?

The reason is Gravity (and maybe clumsiness in the first place)!

Gravity is one of the four fundamental interactions of nature. Objects with mass are attracted to each other and the amount of attraction is proportional to their masses and the inverse square of their distance.

Considering the size of earth and all its mass there is very strong gravitation or a gravitational field, being the reason that we are attracted to earth. (There are other attractions like love who don’t belong here…) Now Gravimetry is the field of Geophysics that measures the gravitational field. You might say ‘I heard that earths gravitational acceleration is g=9.81 m/s2!’ But fact is that depending on mass variations in the subsurface, the latitude and the tides this value varies slightly. With Gravimetry we are able to measure these small variations which can be smaller as…
