More Gravimeters, now with piezo film and single lens interferometers

https://www.researchgate.net/project/iLens-Interferometer-towards-a-new-class-of-frugal-devices I’m interested in this research – could you provide the full-text for it? – Richard Collins I was searching arxiv.org for “piezoelectric film” “piezo film” which can be used for low cost vibration and acceleration measurements. I want to use it for a sensitive three axis gravimeter at high sampling rates. I found your

Note to SETI – Is anyone searching the gravitational signals?

When I was at the University of Maryland at College Park in the late 1970’s I met Joe Weber and Charles Misner and others who were starting gravitational wave detection. So I have followed it over the years. I think it very unlikely that aliens would be using the very narrow band of electromagnetic signals

Comment on Nuclear Desalination Report

http://Article Nuclear Desalination: A State-of-the-Art Review Thank you for putting this together. This is a clear, and fairly complete, review of the issues, economics, performance and maintenance of nuclear desalination processors. I just wish that each site’s operational, financial and social impacts were public on the Internet in a form for comparison and optimization. Encouraging

Is there an Internet data policy for SKA and related data? Human value of shared raw, live data streams

Karen Lee-Waddell, Pete Wheeler, SKA web contact, I am trying to piece together the Internet data sharing policy for SKA from what is visible on the Internet. Is SKA data going to be available to everyone on the Internet?  In accessible form? Reading these it seems SKA data is only for certain people for very

Models at CCMC, Vitmo ModelWeb Browser Results, Fundamental constants and equations used

Hello, I was enjoying your model site.  One of the better ones on the Internet in terms of ease of use and clarity. The only thing that I would like different is to have parameters in the generated URL, so that I can bookmark a run and go back to it again, without manually entering

Houston Astronomical Society Presentation by Noah Pearson on 28 Jan 2022 – comments and suggestions

Luis, This was a good presentation.  On Vimeo, watching reruns, no way to say “Thank you to the presenter” or to ask questions. We live in a world where any author’s work might be available globally for all time forward.  And, it they are living, the small matter of “time” it taken care of by

Comment on Sally Pias – Molecular Modeling, Cholesterol, Oxygen Diffusion, (diabetes)

Dr Sally Pias | Molecular Modeling Changes How We Interpret EPR O2 Measurements | O2M Webinar Series https://www.youtube.com/watch?v=QmcGZy_xZEA Sally, thanks for the link to your paper. I found you on ResearchGate, but it only has the abstract (unless I missed something). I like your visualizations and discussion. I see your paper on proteins and membranes,

Mars and moon and space need atomic power – shipping to Mars example

SpaceX Starship can return from Mars without surface refilling at https://www.youtube.com/watch?v=u55zpE4r-_Y The engineering design and manufacturing costs for atomic power are a lot less than the cost of hauling chemical or solar panels to Mars. Do the numbers and see what it is worth to spend on lightweight atomic power units and technologies. A few ten

Comment on Earthquake Seismograph Using Bismuth Magnetic Levitator – about state of the art in low cost gravitational detector arrays

Earthquake seismograph using bismuth magnetic levitator as sensor at https://www.youtube.com/watch?v=aIANNzpec7Y Tomislav Stimac, The “standard” still for accelerometers is the small but global network of super conducting gravimeters (SGs). They use liquid helium cooled niobium magnetically levitated spheres as the test mass. The sensitivity is about 0.1 nanometers per second squared (nm/s2) at 1 sample per second.

Comment on a wonderful recipe

It’s so delicious that I cook it almost every day! incredible recipe # 10 at https://www.youtube.com/watch?v=4G54qzw7iQM The food is beautiful. Your methods and cooking show well. It is easy to see the care you put into making textures that fit the cooking, and probably taste good and are satisfying to eat. But, you need context.
