Hello, I had reason to write out some of what I found measuring the speed with which the gravitational potential comes to equilibrium. It is rather long, but perhaps might be useful. I am trying to encourage the development of arrays of three axis, high sampling rate gravimeters to use for imaging sites of interest

https://www.researchgate.net/publication/353838684 Recommend you change the title to “Can we ever replace the gravitational force model with something more practical, so we control the forces?” Mircea, Did you ever get an answer to your question? Masses with relatively small number of free charges per kilogram can have electrical forces equivalent to the gravitational force.

DOUBLE VORTEX solves mystery of Saturn’s rotation | ft. Tom Stallard & Nahid Chowdhury https://www.youtube.com/watch?v=pVlV7Er_jFU Does this apply to galaxy rotation? I would much rather hear that a relatively small bit of charge and magnetic field – changes apparent rotation rates – than the bleak alternative of still more years of looking for dark matter

https://www.youtube.com/watch?v=IhG_qHAvJd0 Fairly certain there is not enough information from one magnetic sensor to uniquely determine the position and orientation of the floating magnet. Once you actually measure the position and orientation of the levitated mass, its magnetic field, and the shapes of the supporting field. Then it is much easier. Do you think those rockets

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

Luis, This was a good presentation. On Vimeo, watching reruns, no way to say “Thank you to the presenter” or to ask questions. We live in a world where any author’s work might be available globally for all time forward. And, it they are living, the small matter of “time” it taken care of by

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.

Teri, I was doing a quick study on “color from structure” and related concepts. The colors of butterfly wings are often not pigments in the traditional sense, but emergent colors because of the shapes of the molecules. What clicked in my mind is that the sub wavelength structures (the structures that produce the rather large

Jean, I want to find a contact image sensor CIS that has high dots per inch, large color depth (bits per pixel color) and fast speed (lines per second). I need three of them, and don’t know where to buy the parts. I just started looking and found that the mobile document scanners (Brother) seem
