New Video – Some NOAA Visualizations Data Projections More Gravity Sun Moon Global Cooperation

Some NOAA Visualizations Data Projections More Gravity Sun Moon Global Cooperation https://youtu.be/4waIa-2tMlY My comments and a few suggestions. Then another pitch for global cooperation, and for help with gravimeter arrays to scan the atmosphere, the oceans, the earth interior, the moon, sun and planets and moons. Richard Collins, Director, The Internet Foundation The video refers

Notes from Weather.gov survey questions.

Internet Research – global sensor networks and sharing Looking for data to correlate with other sensor networks Your left bars are rich in links. But you are using almost a different style of navigation on every page, certainly every section. With about 3 Million entry points for site:weather.gov that is a lot of hand building

Comment on video to measure wavelength of sound and apply reasoning

Waterloo Double Slit 1 at https://www.youtube.com/watch?v=acgb5uP4CBM David, I think it would help viewers if you draw a wave on a transparency and overlay it onto another wave to show what is happening. Put two arbitrary time series and look where they match or do not as the time difference changes. Put a time series made

Comment on “Aerodynamic Center and Center of Pressure location. Computation and Misconceptions”

​At https://www.youtube.com/watch?v=67eTLeNwLgE Alexander, You are using what looks like to be a good computer tool for these calculations and visualizations. But you don’t explain your tools and give links to let others know what to use, or what you recommend. I watched your hysteresis video. It is really shaky and hard to watch. You could use

Equation Accessibility on ScienceDirect.com, Encouraging Global Collaboration

I like the MathML and equation accessibility of your pages. I am at https://www.sciencedirect.com/topics/engineering/observability right now. But suggest you integrate some tools to immediately use the equations.  You have LOTS of them on your site, and they are disconnected fragments. Collectively they can change the world. And, there is no sense of community on this

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

Gravitational, Magnetic and Electric Field Changes from Global Climate Change

I wrote yesterday about magnetism and gravity and temperature at gravimeter and related sensor array detector sites.  I give averages over all frequencies, but the fine details can be tracked across all frequencies from picoHertz to ZettaHertz. Relation between gravity, magnetism and temperature at the earths surface at /?p=1893 Today I realized that if global

Question for Houston Astronomical Society and anyone else on the Internet

https://www.facebook.com/groups/AstronomyHouston Can you suggest a program to take two images from different cameras, combine and compare them? I am too tired to write more programs. Just wanted to look at some pictures I found on the web and see how the fit together. They are the same part of the sky, but different rotations, different
