blind people can actually study pretty much anything
years ago, for a short time i volunteered at a charity for blind people that made academic audiobooks. at that time textbooks tended not to get turned into audiobooks and there was no text-to-speech etc. blind people could request the charity to create an audiobook and volunteer readers read the book onto cassette tapes. if there were pictures, diagrams etc in the books the readers would describe the pictures
