Ben Krasnow on How To Make An Expensive Microscope Work As Well As A Really, Really Expensive One

2:03 On using cheap microscopes:  you would need to be able to deconvolve the images with the point spread function characterising the aberration of the objective lens. That would probably be a difficult thing to do.

See this Nature article Wide-field, high-resolution Fourier ptychographic microscopy (paywalled) or try the Russian Sci-hub if your ISP hasn't blacklisted the server.  See also Multiplexed coded illumination for Fourier Ptychography with an LED array microscope and Quantitative phase imaging via Fourier ptychographic microscopy.

I wonder whether you could use a technique like this for processing data from Ground Penetrating Radar? I guess not because the medium you're imaging through is highly non-uniform:

A derivative is linearisation, and differential calculus is essentially linear algebra, ...  See  Freya Holmér - Why Can't You Multiply Vectors?  and  Freya Holmér on Continuity of Splines .

Alan Edelman talking about expressing mathematics as computer code. The idea is that you can use computer languages to communicate mathematical ideas precisely to other people.

... and his posterity too? See  On Communication in Linear Time And Hypertext And The Gospel of Sophia . So it looks like El Cielo of the cistine [sic!😂] chapel is not the limit anymore.  I think I just met one of his descendents. A guy called Versailles Toledo who is from Chiapas. That might explain the murals I mention in my recent untitled post , just before the post mentioning this video. I also just took this photo of Rafael Gonzales, born here in Tecate, B.C., who told me about a spring near here called Agua Fría , half way from Tecate to Loma Tova , where, a few decades ago, people used to go to have barbecues and stuff, but now he thinks it may be private land. If someone reading this has a Facebook account, please write a link to this post onto his FB page. To see why I took the photo, look at his T-shirt and the horse-shoes and ponder this: Subscribe to BeatrizER and her video(s?) about mathematical logic, ...
