Gravity and Temperature, gravity and pressure

Shawn, What I am saying is that the energy density of the radiation field of the earth, which you can map by mapping the temperature is just “gravitational field stuff”.  The magnetic field of the earth which you can convert to magnetic energy density is also made of “gravitational field stuff”. The gravitational field of

Comment on my video Windows USB GPS Device Based on UBlox Chip and UCenter Software

Windows USB GPS Device Based on UBlox Chip and UCenter Software https://www.youtube.com/watch?v=uJZHVKGrl6Y @Ali Zitouna Hamed, I am not sure what you mean by “base ntrip”. I made this long ago and have not used UBlox lately. Since then i have been working on software defined radios, electromagnetic interference, gravitational wave detection, imaging arrays for gravitational

Comment on Aerodynamic Center and Center of Pressure

Alexander, https://www.youtube.com/watch?v=67eTLeNwLgE 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

Comment on a video about spatial filtering

Intro to Fourier Optics and the 4F correlator https://www.youtube.com/watch?v=wcRB3TWIAXE Great presentation! My physics professor showed me this in the lab one day, more than 50 years ago now. He used black and white microfilm and microfiche. He showed me newspapers on microfiche that could be searched for specific things. Your clearer explanation of how to

Comment on Pictor Open Source Radio Telescope – Recommendations

https://www.youtube.com/watch?v=70plmWJDt2k Open Source: https://github.com/0xCoto/PICTOR Website: https://www.pictortelescope.com/ Please leave the settings and all form fields. Don’t clear them. Just leave them the same as the last observation.  I am having to re-enter them ever time I make a request.  I am making series of requests.  Many people might.  Tell them how many files they will receive, how many

NANOGrav raw observing data – merging all global sensor networks on the Internet

Hello, I was visiting https://data.nanograv.org/ to see what kind of data you are sharing online.  I am tracking most all the sensor networks on the Internet, especially the emerging ones. If I understand this talk by Steve Taylor at https://www.youtube.com/watch?v=_UptA7pkARo you are only observing at widely separated times for about 30 minutes? He talks about

Comment on How much weight can you remove from your car?

https://www.youtube.com/watch?v=MCiNGmwopx4 I would like to see the bare minimum weight by taking everything. That weight in every car is costing fuel and global warming. Think how many cars are for one person. Need more people? — uber it or share. I drove for years with no one else in the car, carrying all that extra

Compressible Euler equations for the vacuum, comments and suggestions

https://www.researchgate.net/profile/Geng-Chen-21 Large solutions for compressible Euler equations http://people.ku.edu/~g828c364/application/Euler.pdf Geng Chen, “compressible Euler equations” shows up on the Internet 109,000 places.  There are hundreds of variations of that term and related models.  I try to find and classify and organize everything on the Internet. “euler” “compressible” “vacuum” “gravitational” has 134,000 entry points “euler” “physical vacuum” has

Luis, This year I joined the Houston Astronomical Society, the Astronomical League and now Texas Astronomical Society. I am a retired mathematical statistician, but I work full time still as Director of the Internet Foundation.  If you want me to bore you to tears about global Internet communities, I am happy to oblige. I have
