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 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
