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

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

Explaining to MathWorks about Infinite Levels of Knowledge and Hover

Jordan, Image Acquisition Toolbox: Your online, and now the attached price list, is not appropriate for “Home” users. Today someone fixed the website issue where the license information was not accessible.  I could not open my account information. Now, when I look at my account information, “Manage Products”, it has  “But Add-Ons” as a working

Comment on Geomagnetically Induced Current Data

https://www.researchgate.net/post/Please_I_want_to_enquire_How_can_I_download_Geomagnetically_induced_current_data_GIC_of_one_minute_time_resolution_data Alaa Mohamed, Today I was just reviewing “global conductivity models” and “geomagnetically induced currents” for the Internet Foundation. The common practice seems to be to use 1D and 3D conductivity models, then use the fairly dense magnetotelluric (MT) arrays for the changing magnetic fields that induce the changes. There are LOTS of electromagnetic datasets.

Comment on Fusion Rockets Video

https://www.youtube.com/watch?v=STtXdpD8LtM Neutrons have a permanent magnetic moment and can be accelerated (controlled) by magnetic gradient fields. This included dynamic gradients of many sorts. And nanoscale fields. search “neutron acceleration” and “neutron deceleration” to see people have not ignored the need to control and use neutrons. There are a thousand times that many people working on

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
