Konrad Lehnert @Berkekey about MEMS gravimeters and other very sensitive accelerometers focused on ‘gravitational’ sources
Physics @Berkekey: Oct 13 Colloquium: Konrad Lehnert at https://www.youtube.com/watch?v=qbqTWe1qBbY Konrad Lehnert, Three axis MEMs gravimeters can be made sensitive enough to measure precisely the vector tidal sun moon signal that is the main part (about 98.5%) of the signal at a superconducting gravimeters station. Using the JPL ephemeris this is just the sun’s acceleration at the
