Making scientific culture accessible to the visually impaired

"Look at this diagram showing the water cycle in order to understand it" - typical instructions from any science textbook. Yes, but what do you do if you can't see the diagram? Nowadays, and for a very long time, the transmission of knowledge has been essentially based on vision. We refer to this primary sense for absolutely everything. Faced with this situation, the question arises: how can we give visually impaired people access to all this knowledge? This book looks at existing ways of transmitting culture other than through vision. It also looks at the problem of transforming content: how do you give access to content that is originally visual, without transforming the meaning of that content? This is a work in progress. Tactile images, mental representations, audio terminals or even visually impaired, blind or born blind... This book also aims to help people understand the subtleties of visual disability. One of the theses put forward in this book is that facilitating cultural access for a minority makes it easier for everyone.
