Comment on Geomagnetically Induced Current Data

https://www.researchgate.net/post/Please_I_want_to_enquire_How_can_I_download_Geomagnetically_induced_current_data_GIC_of_one_minute_time_resolution_data Alaa Mohamed, Today I was just reviewing “global conductivity models” and “geomagnetically induced currents” for the Internet Foundation. The common practice seems to be to use 1D and 3D conductivity models, then use the fairly dense magnetotelluric (MT) arrays for the changing magnetic fields that induce the changes. There are LOTS of electromagnetic datasets.

Comment on Fusion Rockets Video

https://www.youtube.com/watch?v=STtXdpD8LtM Neutrons have a permanent magnetic moment and can be accelerated (controlled) by magnetic gradient fields. This included dynamic gradients of many sorts. And nanoscale fields. search “neutron acceleration” and “neutron deceleration” to see people have not ignored the need to control and use neutrons. There are a thousand times that many people working on

Compressible Euler equations for the vacuum, comments and suggestions

https://www.researchgate.net/profile/Geng-Chen-21 Large solutions for compressible Euler equations http://people.ku.edu/~g828c364/application/Euler.pdf Geng Chen, “compressible Euler equations” shows up on the Internet 109,000 places.  There are hundreds of variations of that term and related models.  I try to find and classify and organize everything on the Internet. “euler” “compressible” “vacuum” “gravitational” has 134,000 entry points “euler” “physical vacuum” has

Archiving and Sharing lossless sky data for all the people on earth

Dominic, I spoke to Chuck Allen, vice president of the Astronomical League, yesterday — https://www.astroleague.org/al/general/contact.html “The Astronomical League is composed of over two hundred and forty (280 now) local amateur astronomical societies from all across the United States.” https://en.wikipedia.org/wiki/Astronomical_League (pretty thin description) https://en.wikipedia.org/wiki/List_of_astronomical_societies We talked almost an hour about the growth of Internet sharing (I

Thank you to Jonathan at Bangor University for Reference Image

The Grid:  https://csee.bangor.ac.uk/wp-content/uploads/2020/08/regular-grid-random-colours.png Jonanthan, Bangor University: https://csee.bangor.ac.uk/cy/project-rainbow/create-a-coloured-grid-in-processing/ Jonathan, Thank you. I was working on a simple camera calibration and needed a good target. Your random colored grid made a great clear image. Correcting the camera colors, positions and intensities is much easier with a quantitative reference. The only suggestion I have is to also have the Javascript

All sky live cameras for teaching, research and learning to collaborate globally

Luis, Attilla —  Hi Dodie, Gary, I appreciate you looking into this.  I got a separate reply from Attilla Danko offering to help with monitoring and reporting on all sky visibility.  Lenses that see the whole sky will have visible areas on parts of the sky.  I have found live cameras where a few stars

Gravity Research Foundation Campaign, Gravitational Engineering, Simulating Gravity

Samir, Glad you noticed it.  Most of my messages never get answered or noticed.  I guess they mostly get treated as spam.  I try to not let it bother me. Your paper is online now.  I guess I was in a hurry to read it.  It has a really ugly URL.  It really needs to

Comment on: Trabecular bone organoids, synthesizing earth-like gravity equivalents

Trabecular bone organoids – A micron scale prototype designed to study the effects of microgravity and degeneration – https://www.nature.com/articles/s41526-021-00146-8 Alexandra, I received this note today about your work.  I have been tracking most all the levitation technologies on the Internet for some time. Then I realized that you probably know all this already, except maybe acoustic

Comment on: What is Clay by Miss Territo

https://www.youtube.com/watch?v=RgzW_qRRRLs Taking clay from natural soils requires mixing with water, settling, separation. Or crushing and dry separation, to get the fine enough particles that have the properties you want or need. And usually a degree of experimentation and learning to find the right sizes and properties that give different ultimate results. And some luck and

Comment on BriTheMathGuy This Sum Amazes Me Every Time – Covid, Internet, Math on the Internet

https://www.youtube.com/watch?v=tGcZDq2bmxM I turn off the sound, turn on the captions, set the speed to one quarter, and don’t look at you gesturing. Plenty of time and fewer distractions. Highly recommend using screen videos. Work out your presentation on the computer, record as you go. Explain the steps and move the pieces around yourself in real
