If you can actually reflow and resize a math/science textbook there's no reason it can't work on a 6" screen but with many titles still shipping horrid versions that use images for equations for kindles/ancient readers that are almost always blurry AND the wrong size to surrounding text often considerably so. This is especially bad after being used to crispy gorgeous TeX-made PDFs.
Way back in the early days of ePub 2, I did see a scientific document that was brilliant. It reflowed and the math was done with SVG. There was no need for PDF. It reflowed and the math resized correctly. It displayed no problem on a 6" eInk screen.
