Please correct an error on Sciencing.com, Physics of Plasma Globes

I happened on a nicely done study of the plasma ball.  The filaments are re-created every cycle.  They start as spherically symmetric (probably depending on the roughness of the sphere they use) and then extend outward at fast but finite speed. Each cycle, the tendrils (that is the most common name so far) follow the

Note to Astronomical League

https://www.astroleague.org/ I found a few YouTube live all sky cameras. They are for weather, weather research, astronomical viewing planning, a tiny bit of actual teaching of human astronomical methods, some moon and sun projects, some cosmic ray and lightning, some comet, some other things. I just wondered if your members and groups are doing this,

Comment on Google Search for “temperature energy” with no count

You forgot to put the count of the results when you put these buttons at the top for “temperature energy”. Contact me if you would be willing to share counts from Google searches for profiling the whole Internet. You are missing opportunities. Some high profile survey results for the Internet might help. Add “Comment or

Add “donate and support buttons” to Wikis and online pages

Dear Thoughtful and Caring Wikipedia Workers, Designers, Helpers, Gatherers, Visualizers, Programmers, Database people, Donors, Online Communities connected to and using Wikis, or workers on any page on the Internet: I am visiting https://en.wikipedia.org/wiki/Calca,_Peru because my daughter sent me a photo from there. But it is a stub. I found a few things on the internet

Comments on UCAR community registration and purpose, global climate change

I was looking at https://climatedataguide.ucar.edu/climate-data/gpcp-daily-global-precipitation-climatology-project where it says “Become a Registered User”. Courteous, inviting. But click and it says, “Access denied, The page you requested requires that you login.” So it seems to login you have to register, and to register you have to be able to log in.

Comment on Mars Helicopter Snaps color image – Metric, Documenting, Teaching, Sharing

​You are very thoughtful. Yes, I agree about the usual human practices and methods. Every single one of the tens of thousands of groups I studied in detail on the Internet ended up failing or limiting themselves because of the greed of a few people, or policies that benefited only their group. It is particularly

Comment on Persistent luminescence instead of phosphorescence

https://www.researchgate.net/publication/327939317_Persistent_luminescence_instead_of_phosphorescence_History_mechanism_and_perspective/comments Enjoyable read with many thoughtful ideas and descriptions. There are several energy sources for these photon flows, but thermal energy harvesting over long periods, then optical photon emission for shorter periods seems to be the theme. The energy stored in electronic states.   I am posting this on 18 Apr 2021: “persistent luminescence” has

Comment on Gold on Mars Video

https://www.youtube.com/watch?v=mvKrwSNy69Q The rovers have x-ray spectrometers to determine elemental compositions of Martian rocks and materials. https://mars.nasa.gov/mer/mission/instruments/apxs/ https://en.wikipedia.org/wiki/Alpha_particle_X-ray_spectrometer Ralf Gellert is the principle investigator for the Curiosity APXS. I suppose you could ask him if they checked. They probably are doing random samples of everything, and might be able to estimate elemental abundances, including gold, in
