In many disciplines of physics, code is not explicitly discussed as part of the learning subject. Here I will focus on nonlinear dynamics, a discipline that suffers greatly from the disconnect between the mathematics and the coding. I will present our new approach in teaching this subject, based on JuliaDynamics and a new Springer textbook for nonlinear dynamics whose pages are interlaced with Julia code. I wish to demonstrate how Julia can fundamentally change the way physics is being taught.
