All “exact” models have to live in the real world, even Rapunzel had supplies and an early form of Internet

Richard K Collins Assistive Technologies, Gravitational Engineering April 17, 2024

Physical Review Letters @PhysRevLett An exact full set of matrix product states of highly degenerate tricritical Lifshitz points in the quantum spin model with anisotropic interactions has been discovered https://go.aps.org/3Q3Pxna https://pic.twitter.com/w22Em2B3EZ Replying to @PhysRevLett It only looks simple because you use simple potentials with no real world inputs. In the real world, every tiny cubic

Sub nanosecond flash 3D video sampling allows gravitational imaging, “imaging accelerometry”

Richard K Collins Electrokinetic Electrodynamic Field Methods, Electromagnetic Gravitational Field, Gravitational Engineering March 28, 2024

I am interested in your “double exposure”. 200 ns would be 5 Mfps. Can you say which specific cameras from Imperix or elsewhere can support that? I am also interested in LWIR “thermal” camera for passive radiometry. Do you have anyone interested in camera interface standards? There are many cameras, and the cost of storing

Add diamagnetic gravimeter to the list of ways to make chip scale gravimeters and their imaging networks

Richard K Collins Electromagnetic Gravitational Field, Gravitational Engineering, Sun Moon Vector Tidal Signal March 25, 2024

Diamagnetic magnetic levitation at nanoscale is one way to make chip scale gravimeters. A “gravimeter” is an accelerometer that can track the sun and moon by their gravitational fields precisely. https://arxiv.org/abs/2105.13555   The three axis signal allows “gravitational GPS/GNSS” and “gravitational compass” in 3D. Array for imaging atmospheres, oceans, magma and interiors of things. After

Updating a link on Hackaday.io for Low Cost, Time of flight, gravitational imaging arrays

Richard K Collins Electrokinetic Electrodynamic Field Methods, Gravitational Engineering January 12, 2024

​https://hackaday.io/project/164550-low-cost-time-of-flight-gravimeter-arrays/log/208711-more-information-posted-at-researchgate-on-3-axis-gravimeters/discussion-195371 https://www.researchgate.net/profile/Richard-Collins-16 ResearchGate canceled their project support last year and I managed to save some things before they erased everything. I had/have a few dozen followers and collaborators.  I have been working on many things and still many different designs and things related to gravitational imaging.  But I am not making devices, only checking components. Do you

Every day gravity is Newtonian, and gets more interesting at higher sampling rates

Richard K Collins Gravitational Engineering, Sun Moon Vector Tidal Signal December 30, 2023

https://twitter.com/RichardKCollin2/status/1741046739237228715 Sensitive three axis gravimeters show that vector sun moon tidal signals are nearly perfectly Newtonian, only requiring three linear regressions (6 numbers) to lock a station to the sun and moon for position and orientation sensing. Many types now.   https://twitter.com/RichardKCollin2/status/1693165581329985565   This is one month for the vertical component of the vectors signal.

CLaE @leafs_s  nature Mysterious ultraslow and ordered activity observed in the cortex https://nature.com/articles/d41586-023-03795-9 Replying to @leafs_s You might look at what Ilya Prigogine and Dilip Kondepudi wrote in 1983 after Prigogine got his Nobel prize. “Sensitivity of Nonequilibrium Chemical Systems to Gravitational Field” DK Kondepudi, I Prigogine. It is listed in Google Scholar and there

Gravity is often ignored or considered constant or negligible. Gravity has a wide measurable spectrum, from at least nanoHertz to gamma ray frequencies.

John Preskill @preskill “The goal of airing some skepticism, [Matthias] Troyer says, is not to diminish interest in the field, but to ensure that researchers are focused on the most promising applications of quantum computing with the greatest chance of impact.” https://spectrum.ieee.org/quantum-computing-skeptics Replying to @preskill John, besides, offering skepticism, or simply pointing out directions with
