Comment on Comment – Supernova near the earth 2.5 M years ago

Where do the elements come from? Nucleosynthesis in stellar environments at https://www.youtube.com/watch?v=6C-F7afeupw Interesting. (“fe60” OR “al36”) “supernova” has 6170 entry points (Google, 26 Jun 2022) and fairly rich in particulars Interstellar 60 Fe on the Surface of the Moon at https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.116.151104 Limits on Supernova-Associated Fe 60 / Al 26 Nucleosynthesis Ratios from Accelerator Mass Spectrometry Measurements

Update on Richard Collins “Solar System Gravimetry and Gravitational Engineering” project on ResearchGate

https://www.researchgate.net/project/Solar-System-Gravimetry-and-Gravitational-Engineering I was updating my notes of gravimeter arrays as gravitational imaging arrays. At the end I recommend using electrons interferometer and related electron methods for measuring and monitoring acceleration. Every electron on earth has mass and is affected individually by the changing gravitational field. Electron methods are far in advance of atom methods, less

Comment on Computational Microscopy Video (includes lensless methods)

Computational Microscopy by Laura Waller https://www.youtube.com/watch?v=sCCGnxRoUr4 Your diagram at 18:05 is not the way it works. Your every day matrix methods ALL are used by tens of thousands of groups and individuals all using related methods. The things you do not know, mostly there will be others who do. If you haven’t learned something yet,

Comment on Video Removing Heavy Wind Shake from FPV footage

Removing heavy wind shake from FPV footage at https://www.youtube.com/watch?v=iDRJCyCKWfQ I have been collecting live video streams on the Internet for some time. I call the collection “shake wind”. Mainly beaches, bridges, mountains and places where the wind is fierce and the camera will often shake, sometimes violently. But the equation of motion of the camera is

What is the ratio of nuclear to gravitational energy for the sun during its whole life cycle?

David, I was starting to read “Submillimetre Astronomy” by Watt and Webster and they were talking about molecular clouds. They mention the magnetic energy density being approximately equal to the kinetic energy density, then talked about a cascade of scales.  It has been on my mind to check how much nuclear energy in generated in

Scripting with video samples and Forum posting, Multiple camera clusters, arrays and sharing

Hello, I have been using Sharpcap for testing cameras.  But I am only now getting things set up after several years of trying to select or design the telescopes and cameras. For single cameras I am running these kinds of manual captures. I have to manually set the gain, exposure and processing steps. Then I

Comment to All Sky Camera group

https://www.facebook.com/groups/172438633343696 Can someone tell me the current best all sky set up? I was thinking of one that had zoom from all sky to 30x. Any suggestions. Thanks. I was looking at PTZ low light security cameras. Dan Bush Thank you. Your picture gallery is filled with beautiful images. I searched fro Hikvision cameras and

Comment on Houston Astronomical Society website and practices

Debbie, First, your novice videos should be globally public on your website.  Either HAS is an organization devoted to all people knowing about the sky and heavens, or not.  Share openly.  If there are things specific to secure gatherings at private places, those should not be shared, but minimized or separate.  I tell groups like

Comment in Microwave Handy Scanner

https://www.youtube.com/watch?v=vDyo_OQFdAc I doubt that you read comments that come years after you make a video. But I will leave this in case anyone wants to try to improve on this. I think it is a really good idea and there are lots of tools and methods to improve on it. Particularly for humans, but for

Piezoelectric film and fiber, Three Axis, High Sampling Rate Gravimeters for Imaging Arrays

https://hackaday.io/project/164550-low-cost-time-of-flight-gravimeter-arrays/log/203460-piezoelectric-film-and-fiber-three-axis-high-sampling-rate-gravimeters-for-imaging-arrays I have not posted updates here for a while, but I work on this continually.  The latest possible technology that I will be trying to adapt is related to piezoelectric films and piezoelectric fibers.  I have seen several efforts to use piezo disks, but not these films.  As I am reading the history of these materials
