The video presents two challenges: one in music and another in measure theory. The first challenge explores musical harmony through frequency ratios, discussing how rational and irrational numbers affect harmony. The second challenge involves covering rational numbers between 0 and 1 with open intervals, where the sum of the intervals' lengths is less than 1. The solution involves listing rational numbers and assigning intervals, demonstrating a counterintuitive result in measure theory. The video concludes with a visual explanation, connecting the two challenges and highlighting the surprising nature of the results.
