Scott Manley: Artificial gravity, 3D time dependent acoustic and electromagnetic acceleration and excitation fields

Scott Manley: Can The Human Body Handle Rotating Artificial Gravity? at https://www.youtube.com/watch?v=nxeMoaxUpWk Scott Manley, One of the offshoots of the very fast development of 3D acoustic and electromagnetic imaging and levitation research, is that it is now possible to measure and control fields sufficient to create 3D fields of forces, that match precisely the impulse response

See the Pattern: Casimir forces, measurng and calculating 3D fields efficiently, Gravitational energy density and engineering

See the Pattern: Casimir Effect – What causes this force? at https://www.youtube.com/watch?v=OgJj49ws478 See the Pattern, To represent 3D fields, it is relatively easy to find many orthogonal representations. For atoms and molecules the groups often start from the Schrodinger equation, or the nonlinear Schrodinger equation. It is also possible to use 3D Fourier and wavelets. There

Large airplanes can go global, electromagnetic and look ahead

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

Note to Angstrom Engineering about Magnetron sputtering for space propulsion and applications

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.

Earth to orbit and hypersonic point to point, rocket propulsion optimization has orders of magnitude potential

Vidduley: Electrodeless Ring Discharge History (since 1884!) at https://www.youtube.com/watch?v=Nu6VvNJN8XM Wade Cooper, Don’t just focus on the electromagnetic fields, but spend as much time on acoustics. The ions carry a lot of the mass and energy. USE SI units (Pascal and Kelvin) most of the literature will use those units and you will waste a lot of

Earthquake early warning for mitigation and energy harvesting, atomic scale computing

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

Note to NIST about gold Au typos The Thermal Expansion of Pure Metals

Hello, I was looking at The Thermal Expansion of Pure Metals: Copper, Gold, Aluminum, Nickel, and Iron at https://materialsdata.nist.gov/handle/11256/32 It has a spreadsheet.  In the “Au data” sheet There is a temperature 38136.  I think that ought to be 381.36. The value for 157 centigrade, 37.3417?  Should it be 0.00373417? The value at 34.6 centigrade,

Project update – omega squared for high sampling rate gravimeters

Accelerometers and gradiometers get better at higher frequencies, use the Internet to multiply capabilities many fold https://www.researchgate.net/project/Solar-System-Gravimetry-and-Gravitational-Engineering These “updates” are just things I think are important to remember, and what I can find time and energy to write down. If you see something you disagree with, write me or make a comment. I got a

Electron Affinity, open sites, and new more precise sub electron volt cameras and sensors

Measurement of the electron affinity of lead and its isotope shifts at https://journals.aps.org/pra/abstract/10.1103/PhysRevA.106.L010801 Physical Review A @PhysRevA 3h Letter: Measurement of the electron affinity of lead and its isotope shifts @DenisonU @vassalloef https://go.aps.org/3BkBPpl https://pic.twitter.com/zVlUBLp75Z Replying to @PhysRevA @DenisonU and @vassalloef Looks like a lovely and precise study. I have been following “electron affinity” for years.
