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

Comment on Electromagnet for attracting copper

Electromagnet for Attracting Copper, Aluminum and Non-Ferrous Metals like GOLD! https://www.youtube.com/watch?v=_mQeaKkaEcQ Yes, vary the frequency and measure the force response. A spectrum is easier to use and understand. There should be specific resonances for each kind and shape of material. Electric and magnetic polarization studies of materials have been tried since earliest days, but have

April Fools Day comment on DOUBLE VORTEX solves mystery of Saturn’s rotation

DOUBLE VORTEX solves mystery of Saturn’s rotation | ft. Tom Stallard & Nahid Chowdhury https://www.youtube.com/watch?v=pVlV7Er_jFU Does this apply to galaxy rotation? I would much rather hear that a relatively small bit of charge and magnetic field – changes apparent rotation rates – than the bleak alternative of still more years of looking for dark matter

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

Superhalogens, hyperhalogens, hyperatoms, and controlled nuclear decays

Walter, This morning I was going over the magnetic, isotopic and chemical properties of manganese, and all the industrial and societal uses. I came across the terms “superhalogens” and “hyperhalogens” “hyperhalogens” OR “superhalogens” OR “hyperhalogen” OR “superhalogen” has 20,500 entry points There are LOTS of related terms – superalkalai, superatoms.  People like to make their

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

Can You Modify A Car To Save Fuel? – Fifth Gear https://www.youtube.com/watch?v=39g5D7h7jf8 The weight reduction impact shows up if you start and stop as part of a test. Aerodynamic drag goes as the density of air times the velocity squared. You should have waited for a day identical to the first. You guys are in

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
