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

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 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

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

Comment on Equations for Reactance and Impedance Equations Video

Physics – RCL Circuits With Reactance and Impedance (1 of 2) https://www.youtube.com/watch?v=IVS-vjHdC1c I like your video. But I put the equations and data into a spreadsheet, and could play with scenarios quickly. This is an old video. I hope you are encouraging people to use computers to manage the equations and data. Teach them to

Comment on Planetary Data System

https://pds-ppi.igpp.ucla.edu/search/view/?f=yes&id=pds://PPI/CO-E_SW_J_S-MAG-2-REDR-RAW-DATA-V2.0/DATA I like this site. It took me a while to understand it. But I don’t see the SIZE of the datasets in Bytes so I can plan on how large they might be and how long to download. And the tools that I need I have to find by reading. But that (the dependencies

Comment on Small and Large Gaps Between the Primes

https://www.youtube.com/watch?v=pp06oGD4m00 All this wonderful insight and technique, and most is lost because he does not store anything in the computer in a form that can be readily verified and improved upon. Yes, you can use symbolic math tools, rather than chalk. Human memory has carried us so far, but more people will benefit from communicating

Note about why I built Sculptor.Org

J, I talked to my sister, T, yesterday. She is one who has painted all her life. Maybe she will have time and space to do it again. For ten years, about 20 hours a week, back from about 1993 to 2003, I ran a website for sculptors. At the end it had 50,000 unique
