Ask HN: Recommend a maths book for a teenager?
During the first year of my undergrad someone introduced me to Gödel, Escher, Bach. I thought it was mind blowing at the time and still find it to be an incredible introduction to formal systems, thinking mathematically and understanding the concept of proofs.All these concepts are central to higher level mathematics, and are not covered in high school (at least not the Danish one).I'm was very thankful for that introduction, hopefully they would be as well :)
