With MathML epubs can look decent. For example take a look at the sample MathML epub "A First Course In Linear Algebra" [0] (in a reader that supports MathML of course). It looks pretty good. The problem is Amazon STILL doesn't support MathML, so publishers just churn out a gross version where all the equations are images and so then it doesn't scale properly with the text and the book becomes 300+ MB because of it. And they can't be bothered to make two versions for readers like Kobo that do support MathML.

MathML is not good enough. HTML+KaTeX/MathJax would be good enough, but is not properly supported in any epub readers I know of.

I tried the book. There are several places where long equations are cut off. Other minor spacing issues here and there.
