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

Video about NASA.gov – draft sketch of some issues and ideas

Ben NASA Profile Video 1 Trying to summarize the methods and issues and goals https://www.youtube.com/watch?v=aARsXPWQnRo This is a draft review of some NASA.gov pages. I am trying to formalize and simplify the recommendations for the whole Internet. NASA is so important to the human species right now. If this solar system colonization goes smoothly and

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

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

Are 3D simulation results shared globally in an efficient manner?

David, I came across an old video on YouTube that refers to PSAAP.  Here is the link: Towards air-breathing hypersonic vehicles through numerical simulations – PSAAP at Stanford by Ivan Bermejo-Moreno https://youtu.be/llM8RSGagXI?t=120 In this simulation, at two minutes, it is showing cross sections.  I was wondering if, in any of these 3D simulations you do,

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
