The cold atom absolute gravimeters are intrinsically sensitive to its orientation due to the Coriolis effect, which should be understood clearly and compensated for field applications. The sensitivity on the orientation for a free-fall atom gravimeter is investigated in this paper. The apparatus is simplified and improved a lot such that fast adjustment and measurement could be carried out within 20 minutes. From the experimental results, it is found that the orientation angle has a dominant influence on the absolute gravity measurement, especially when the horizontal velocity of atoms is non-negligible. Besides, the magnitude and direction of average horizontal velocity of the detected atoms are obtained in this experiment. In particular, the direction of East-West has been measured by the atom gravimeter itself, such that gravity bias arising from Coriolis effect is estimated precisely.

For many years, major theoretical efforts have been underway to unify gravity and the other forces. Today I suggest a different direction for unification; that of the unification of action and entropy. Exploring a few different derivations of this governing thought, we unveil new physics in that the variance of a particle is dependent on its absolute velocity. While this theory has multiple simple arguments that point in the same direction, it might seem speculative. Thus, a testable hypothesis is put forward that particles move via the discrete Bernoulli process which is a core assumption of these derivations. Still anticipating resistance to exploring this line of thinking, an experiment to measure the variance of jitter was undertaken. The experiment has collected 2 years of continuous jitter on 2 clocks and calculated the Fourier Transform of its magnitude. Three spikes in the data, which combine to 19+ sigma away from current theory, are not only predicted by our hypothesis, but the best fit parameters of the hypothesis suggest the Earth is moving with the same velocity as the Planck collaboration measured Earth is moving in the Cosmic Microwave Reference Frame. Lastly this line of thinking, where one explores the variance instead of the mean value of a particle's location, is worthwhile as it gives insight into the original desire to unify gravity with quantum mechanics.
