Image handling on the Internet, Pixels around a star

Thanks for the links. I spent the last few days going over the NexGen Level 3 Weather radar system. I downloaded many example datasets and tried to review and organize all the parts of it. Looking to see how to integrated radar, satellite, SDR (electromagnetic networks of many sorts), GPS and other sensor networks and

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 how to copy trees and find Birth Parents using Ancestry DNA

I have used Family Tree Maker which syncs to Ancestry. You download the trees to FTM and merge them, and then upload to a new tree. The merging is tedious but better than “save to tree” bit by bit. It is the ONLY method I found that preserves the records as records so that all

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

Low frequency variations of high frequency signals

I have been looking at the general situation of tracking and studying slow variations of fast signals.  If you have a star, its main signal is likely electromagnetic or gravitational.  You track its “colors” with an FFT or spectrometer, and perhaps its slow variations up to decades of years or longer. (“pulsar” OR “pulsars”) “MHz”

Comment to a private group on Facebook about DNA genealogy

This group has grown to over 100,000 members. I see some wonderful advice that should probably be in a globally accessible form. This is a “private” group, so nothing posted here is seen or indexed and available except to people who join. I have helped more than a hundred people with finding their birth parents,

Notes about PixInsight on Houston Astonomical Society Facebook closed group

I have not used PixInsight, but read what they are doing at https://pixinsight.com/. The commercial license is 230 Euros (about $275). They have free versions, but not sure what limitations, if any. All their image processing workshops listed are from 2017. There are software tutorials by their “PTeam” members at https://pixinsight.com/tutorials/index.html I do not know how many

Comment on Google Search Hints for Search for Melting point of Al2O3

https://www.google.com/search?q=melting+point+of+al203 You are giving Fahrenheit temperatures on the Internet, and the global standard is SI. You are not only serving the few people in the world who are still not using Metric, but everyone. Or you ought to. K is the abbreviation for Kelvin. So it looked like you are giving 2.07 Kelvin at first

Comment on Optical fiber coupling to photonics chip

Optical fiber coupling to photonics chip by Wojciech Lewoczko-Adamczyk at https://www.youtube.com/watch?v=rHcfemtfP2s Suggest you use the whole screen for the graphs, equations, diagrams. It is too small to read easily and I do not need to see your face while you are looking at the screen. Such are called “screen videos”, where you and the viewer
