A few that come to mind immediately: 1. Books by VI Arnold. To get a sense of his style, see https://www.uni-muenster.de/Physik.TP/~munsteg/arnold.html https://www.uni-muenster.de/Physik.TP/~munsteg/arnold.html 2. Visual Complex Analysis by Tristan Needham is an absolute treat in visual intution. 3. The road to reality by Roger Penrose. This is an absolute masterpiece building up to cutting edge physics and all the necessary math from scratch. Reading the whole thing is probably a long-term project for most readers, but it can easily be read in chunks, and is an absolutely pleasurable experience (with most of the conceptual substance of a textbook, but without the dry rigor) and a fascinating taste of what/how Penrose sees. 4. From Mathematics to Generic Programming by Alex Stepanov. I've read only small bits from Stepanov, but I'm really looking forward to reading the whole book.
