A visually impaired person may grasp the concepts in "Visual Complex Analysis" by Needham, but their understanding will largely depend on their prior visual experience and the extent of their impairment. The book's mathematical content, heavily reliant on illustrations, poses challenges for those without sight. However, with effective assistance from someone without visual impairment, such as a skilled interpreter providing detailed verbal explanations, it is possible to convey the material. Resources discussing the experiences of blind mathematicians highlight that while visual aids are beneficial, many have successfully engaged with complex mathematical concepts through alternative methods.

Can a visually impaired person understand the book Visual Complex Analysis by Needham? I mean, in principle, e.g., even being helped by somebody with no visual impairment. IOW, can its content be conveyed by pure text, without illustrations?

It will depend on their experience, prior to impairment of their vision, and the degree of their vision impairment. The content is mathematical, with illustrations. A good interpreter, giving a running commentary, might help someone with visual experience.

Im currently reading mathematics for physicists by Philippe Dennery and André Krzywicki, and I’m understanding most concepts however I think it would be better for me to get a book on complex analysis or calculus to better understand it so I’m not left looking at an equation for an hour trying to figure out what it means. So here comes the split, do I get a complex analysis book? Or a calculus book? I might be able to Borrow a calculus textbook from my math teacher study that for a bit and...
