The Unreal in Reality: Top 5 Largest Planes Ever Built In The World! at https://www.youtube.com/watch?v=92tTrLKWlHc Thanks, I was looking to see what the limits might be. I was looking at SpaceX (and competitors) who might want to offer global point to point freight and human cargo. As I watched your list, I was thinking that any

Akira Kokado, You came up with an expression for the gravitational potential. Did you ever convert the earth’s geopotential into your form? [ My son and his small family live in Japan. He decided to go to college there and never came back to the USA. ] I worked with Steve Klosko on the early NASA

Jyoti Lather The “zero point EM fluctuations” are most likely gravitational energy density fluctuations. At the surface of the earth, the gravitational energy density is equivalent to a magnetic field of about 360 Tesla, the peak is about 1500 eV. The distribution is approximately black body and extends through soft x-ray and XUV down

Magnetron Sputtering, E-Beam Evaporation, Thermal Evaporation, Ion Beam Processing at https://angstromengineering.com/tech/magnetron-sputtering/ I was encouraging groups to tackle improving the chemical only propulsion used in things like SpaceX Starship and related earth to orbit systems. Their specific impulse is limited because they do not understand how to generate ion electron and plasma flows with high specific energy.

Signal Decomposition and Feature Extraction Techniques: Application to Seismic Mitigation of Vibration-sensitive Eq Shieh-Kung Huang, This is very informative. I will only suggest a few things. Vibration isolation is now needed for buildings, as an integral part of energy harvesting, to allow orders of magnitude improvement in seismometers and gravimeters, and for gravitational wave

I have learned its limitations and by careful adjustment to the way I write, I can get it go generate words in the directions I want to go. I realized most people cannot absorb

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

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

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

Low Cost, Time-of-Flight Gravimeter Arrays https://hackaday.io/project/164550-low-cost-time-of-flight-gravimeter-arrays More information posted at ResearchGate on 3 axis gravimeters RichardCollins • 07/19/2022 at 17:15 • 0 comments My main “job” is the Internet Foundation, so I am constantly monitoring global issues, methods and activities on the Internet. But I have a heart for research groups and gravitational noise detector
