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

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

NASA Web methods, policies, practices, staff, training, purpose

Emily, I have not forgotten about you and NASA.gov. In fact, I spent many full days checking different aspects of what is going on, who is doing it, who it serves, how much (if any) user involvement is allowed, the level of practice shown in the pages, integration (or not) with contractors and federal agencies,

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
