Answering a question on GSA.gov survey about what I was doing

Re: june 2022 long-baseline neutrino newsletter on the web – suggest you help build a global neutrino collaboration – starting with the US federal labs and GOV domain I was mapping the results from this Google Search which gives 37,200 entry points (today is 6 Jul 2022) site:gov “internet” “collaboration” (“neutrino” OR “neutrinos”) to advise

Comment on Video about paramagnetic resonance algorithms

Dr. Mark Tseytlin | Rapid Scan EPR Imaging Methods and Applications https://www.youtube.com/watch?v=DsVchd3Bzw0 This would be much more useful if you posted links to your papers, particularly General Solution for Rapid Scan EPR Deconvolution Problem https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7575242/ I generally do not recommend Matlab for Internet users. It is too slow and expensive to recommend to billions of

Laser self mixing and laser feedback interferometry and Fabry-Perot cavity precise position measurements

Thank you for sharing your research. – Richard I try to follow all low cost interferometry methods. I started it because of my interest in gravitational imaging arrays and gravitational wave communication. Joe Weber at Univ Maryland College Park encouraged me to work on that back in the late 1970’s. Beside photon interferometry, there is

Comment on Quantifying the potential causes of Neanderthal extinction

Axel, Thank you for sharing your paper.  Academia.edu notified me that you had uploaded it.  I read it this morning, then read it again.  I wish your model was in a form that could be shared more easily. I follow groups using the internet.  I am interested in how people approach complex problems, and the

Comment on Industrial applications of pulsed power technology

https://www.researchgate.net/publication/3340967_Industrial_applications_of_pulsed_power_technology_IEEE_Trans_Dielecrt_Electr_Insul/comments Thanks for gathering this together. But the last decades or so, the cost of high power, high dI/dt controls has dropped considerably – drones, 3D printers, PWM servos, robotics, vehicles. I have only looked at a few areas so far. What you sort of missed was the sensor and control and modeling side. Atmospheric

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

Jimmy Wales thanked me for my donation to support the current Wikipedia. Here is what I wrote back

Jimmy, I would like to make some specific recommendation for upgrading wikipedia to be more useful globally. But I doubt your organization is set up so that a “reply to a message from the founder” ever gets read and treated seriously. My time and skills are far more valuable than any money donation. But only

Comment on Jordan Sullivan, Neutrinos and Antimatter Video

Neutrinos and antimatter at https://www.youtube.com/watch?v=YcpNhPBxwfo Jordan, You can combine a particle and its anti-particle into a stable form, if you provide angular momentum. The external charge and magnetic dipole moments are effectively zero, and the particle is effectively all binding energy which has no mass. The pair can store most any amount of energy, but

Comment on video about the solar interior – another way, with the whole human species working together

What Does The Inside Of The Sun Look Like? https://www.youtube.com/watch?v=8ayHXTnN4fk In the visualization from 3:00 to 4:00, I think there should be small particles coming from every point to every point in the detector. For instance something coming from the far upper right. to the far lower left. Not just radially outward from one point

Comment on Downwind Faster Than the Wind by Veritasium, How Does it Work?

Downwind Faster Than the Wind by Veritasium: How Does it Work? https://www.youtube.com/watch?v=CkhBskovitQ A good quantitative simulation does not need words, and the process of design is more efficient, not maintaining an inaccurate word model alongside the simulation. The words will always be ambiguous, but the model can be calibrated and fit to measurements from the
