Everyone, I am including this as an update to this project because the routine laboratory and wide area measurement of the speed of the gravitational potential is critical to all the groups working together. You HAVE to be able to measure the signals at high enough sampling rates to get good correlations and comparisons. For

https://www.researchgate.net/project/Solar-System-Gravimetry-and-Gravitational-Engineering I was updating my notes of gravimeter arrays as gravitational imaging arrays. At the end I recommend using electrons interferometer and related electron methods for measuring and monitoring acceleration. Every electron on earth has mass and is affected individually by the changing gravitational field. Electron methods are far in advance of atom methods, less

I’m interested in this research – could you provide the full-text for it? – Richard Collins https://www.researchgate.net/publication/345347726_Infrared_variability_due_to_magnetic_pressure-driven_jets_dust_ejection_and_quasi-puffed-up_inner_rims I found this on Arxiv. ResearchGate is saying “request full text” because they or you have to provide a pointer to the arxiv file. Or you have to manually download it. I am interested in your ideas about

Hello, I have been using Sharpcap for testing cameras. But I am only now getting things set up after several years of trying to select or design the telescopes and cameras. For single cameras I am running these kinds of manual captures. I have to manually set the gain, exposure and processing steps. Then I

A MEMS Resonant Lorentz-Force Magnetometer with Both Structural Topology Optimization and Parametric Pumping for Q-Factor Enhancement at Yuan, Life has been interesting lately. I get to work on some of the most interesting questions. Just now I am tracing down some laser wakefield capillary tube x-ray sources. The laser diode groups seem to have gotten

The latest possible technology that I will be trying to adapt is related to piezoelectric films and piezoelectric fibers. I have seen several efforts to use piezo disks, but not these films. As I am reading the history of these materials

https://www.researchgate.net/project/iLens-Interferometer-towards-a-new-class-of-frugal-devices I’m interested in this research – could you provide the full-text for it? – Richard Collins I was searching arxiv.org for “piezoelectric film” “piezo film” which can be used for low cost vibration and acceleration measurements. I want to use it for a sensitive three axis gravimeter at high sampling rates. I found your

When I was at the University of Maryland at College Park in the late 1970’s I met Joe Weber and Charles Misner and others who were starting gravitational wave detection. So I have followed it over the years. I think it very unlikely that aliens would be using the very narrow band of electromagnetic signals

Earthquake seismograph using bismuth magnetic levitator as sensor at https://www.youtube.com/watch?v=aIANNzpec7Y Tomislav Stimac, The “standard” still for accelerometers is the small but global network of super conducting gravimeters (SGs). They use liquid helium cooled niobium magnetically levitated spheres as the test mass. The sensitivity is about 0.1 nanometers per second squared (nm/s2) at 1 sample per second.

Counting Atoms with the Doppler Effect – Heterodyne Interferometer by Sam Zeloof at http://sam.zeloof.xyz https://www.youtube.com/watch?v=vPu6lN9yJOY Sam, I sent you an email about using this to replace the network of superconducting gravimeters with something more people can afford. You have several orders of magnitude available to you by very small adjustments. SGs cost several hundred thousand and
