Summing Up

Many of our discussions in previous chapters have alternated between physics and mathematics, though in the last chapter we saw them intertwined in the concept of duality. In some cases, we have discussed a given topic (A) from the mathematical as well as physical perspective. We then discussed the opposite topic (let’s call it anti-A), again from both perspectives. We also worked through some puzzles that combined ideas from physics and math into a kind of dual picture.
