Can a Penning trapped electron or ion be used as a time of flight gravimeter?

Subject: In your months long measurements on single electrons did you see diurnal variations? Has anyone tried to make a single electron gravimeter? Gerald, I was doing a quick review of linear and quadratic effects in paramagnetic resonance, and happened to notice “Gabrielse and company confined single electrons for months at a time”.  For many

Comment on Visualizing the world’s largest turbulence simulation video

Visualizing the world’s largest turbulence simulation https://www.youtube.com/watch?v=EPe1Ho5qRuM Please post links to your sites. If you have data to share (it can be mere 1000^3 samples or statistical summaries), give people more than just pretty pictures. I think you went too fast. I think your simulations left off all the low density pieces because I don’t

About optically connected processors for home use and many things

Nora, Thanks, I will keep that in mind. If you cast tiny angular (square, triangular, for example) blocks of plastic on ends of an optical fiber, then polish the whole thing, that would give a fiber that would alighn properly with a corresponding hole and fiber (or fibers).  It is something that human hands could

Comments on LibreOffice Sites and Community

Hello, Is there, somewhere, a profile of the Document Foundation community online?  The “LibreOffice community”?  The “Community Map” has no weights or sizes. I looked at the people and groups that you follow, and a bit of who they follow and are linked to.  https://twitter.com/tdforg  I attached my notes. The totals are not indicative of

Comment on Endaq Steve Hanly blog about accelerometer sensitivity

Accelerometer Specifications: Deciphering an Accelerometer’s Datasheet by Steve Hanly https://blog.endaq.com/accelerometer-specifications-decoding-a-datasheet I see you mention temperature sensitivity. I am writing an article on gravimeters and recommending different ones. Someone estimated their response to temperature. It can be estimated for gravimeter arrays. Here is how I estimated it. Relation between gravity, magnetism and temperature at the earths

Why the sun moon tidal signal is so important for helping global sensor arrays with calibration

Shawn, I worked with the US Agency for International Development, the US State Department, World Bank and many international organizations.  Most countries cannot afford to do their own mineral exploration, so outsiders come and take what they have. I helped put microcomputer training and technology into that system so that some countries could afford to

Comment on Planetary Data System

https://pds-ppi.igpp.ucla.edu/search/view/?f=yes&id=pds://PPI/CO-E_SW_J_S-MAG-2-REDR-RAW-DATA-V2.0/DATA I like this site. It took me a while to understand it. But I don’t see the SIZE of the datasets in Bytes so I can plan on how large they might be and how long to download. And the tools that I need I have to find by reading. But that (the dependencies

Solar System Colonization – Comment on How to Terraform Venus video

https://www.youtube.com/watch?v=G-WO-z-QuWI (“terraform” OR “terraforming”) (“venus”) gives 14.3 Million entry points. There is certainly plenty of interest and people talking. The groups and individuals are just not working together effectively. (“planetary engineer” OR “planetary engineering”) has 34,600 entry points. Topic development on the Internet is generally mostly random and undirected. (“planetary” OR “planets”) (“engineering” OR “engineer”

Note in Houston Astronomical Society about Gravitational Engineering

https://www.facebook.com/groups/AstronomyHouston I have been looking at all the radio astronomy groups on the Internet. There are a lot of them, at all levels of age and experience and size. I am trying to see how many of the ground and orbiting networks are also picking up signals in the nanoHertz to GHz range. That includes

Comment on Bessel Beams, Basis sets, Schrodinger equations, Particle-Antiparticle pairs as dark energy and matter

I was looking at Bessel beams and came across your work. You have some good methods and insights. I would like to read where you started. Three things I was thinking about. The Schrodinger equation is usually written in terms of spherical harmonics. But the Bessel functions could be used instead. Just as a basis.
