Relation between gravity and the vacuum impedance is through Z0 = (dB/dT)/(dD/dT)

Why is Coax 50 Ohms? (#340) at https://www.youtube.com/watch?v=I-OnQZJv35I Thanks! Your explanation of 50 ohm cables was very helpful. I wrote a long comment about vacuum impedance you might find interesting. Richard Collins, The Internet Foundation I was going over transmission line theories and trying to get a better feeling for the vacuum impedance which CoData gives

Comment on Video about “Real Capacitors” – When you give people memories of real things, they learn faster

Real Capacitors at https://www.youtube.com/watch?v=hlmPFbHTHTw Sabrina Koffler, You could easily have shown the behavior of a few “real” capacitors as a function of frequency. And added a variable resistance and inductance to show the effects of changing those. Design, testing, measurement is all about numbers, data collection. More and more that also means models, algorithms, comparison between

The vacuum is teeming with real magnetic pairs; some are ‘invisible’ particle:antiparticles with no charge and no moment

Twitter comment on Physical Review Letters @PhysRevLett  Feb 13  Measurement of the Electron Magnetic Moment to 0.13 parts per trillion (replacing a limit from 14 years ago).  Letter: https://go.aps.org/3E3jjSX  Viewpoint: https://go.aps.org/3xfgeLT  Replying to @PhysRevLett  —  One of my favorite experiments. Thanks. I particularly like “according to quantum physics, the vacuum is teeming with virtual particles”. Except I

Comment On The Normal Height Differences Determination From Geopotential Differences

https://www.researchgate.net/publication/359389325_ON_THE_NORMAL_HEIGHT_DIFFERENCES_DETERMINATION_FROM_GEOPOTENTIAL_DIFFERENCES/comments Using real time comparisons via electromagnetic signals gets more complicated. Trying to use high speed storage of the signals gets memory intensive and expensive. As much of the data is nearly the same.   The reason I used the vector tidal gravity signals for calibration and standardization is that each location can compare to

Update to Solar System Gravimetry and Gravitational Engineering

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
