Twitter simulation of fluids stirred by pointed paddles

Richard K Collins 3D Scannning Replication, Process Monitoring and Control, Visualizations Simulations July 27, 2022

Physics Magazine @PhysicsMagazine 8h Simulation videos illustrate how changing different parameters of the system alters how well two fluids mix together when stirred. (For the stirrers, tadpole and teeth shapes are best).

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,

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

Richard K Collins 3D Scannning Replication, Gravitational Engineering, Open Algorithm Development, Symbolic Mathematics, Visualizations Simulations March 14, 2022

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

Machine vision and Industries – ZWO group on Facebook about microscopes and noise imaging

Richard K Collins 3D Scannning Replication, All Sky Cameras, Machine Vision, Process Monitoring and Control October 12, 2021

David, The lens is usually a fisheye or other lens with 1X magnification. You have to add it to a microscope meant for a human eyeball. A decent microscope is expensive and odd shaped for humans, so it does not fit in an industrial or lab or security environment. What I want is a 10x

Comment on old style MIT lab presentations. They are SO slow

Optics: Fringe contrast – path difference | MIT Video Demonstrations in Lasers and Optics https://www.youtube.com/watch?v=IZGnYe7BUms This is like those old serials – always ends with a cliff hanger. How irritating. Some good stuff, glad to see it. But wish he would not be so Socratic, and more measurement and data oriented. But this is a

TheBackyardScientist,  Making Petrified Lightning …with electricity? at https://www.youtube.com/watch?v=m7YznIKe7bU 3D printing metal. You can use metal or glass powders, control the current, and randomly choose next points – probably run on Arduino. You have all the skills and stuff mostly. Maybe someone already suggested. You might invent a way for YouTube viewers to work together, combine

Contact Imaging Sensors, Linear CCD arrays for gravitational and magnetic imaging

Jean, I was trying at least two pathways: 1. Build circuits to read the analog signals from these linear sensors, and put the fastest and best ADCs to read and store the data. The focus on high precision measurement of the signals as a function of reference voltage. 2. Somehow learn to talk to these

Comment on plasma cutting video by Jason Michael Saunders, referring to 3D printed rockets

Richard K Collins 3D Scannning Replication, Atomic Fuels, Gravitational Engineering, Solar System Colonization September 12, 2021

Comment on YouTube Jason, I watched this Genius of 3D Printed Rockets video the other day. They are using plasma discharge heating, but it is not very well controlled at all. They say “it works really precisely”, but it throws off heat and light and bits of wire, and fluctuates a lot. It only needs
