So, I had a really busy day today and wearing the mask didn't make it easier but, health is above all. I started with a new free online course, Introduction to Dynamical Systems and chaos, on Complexity Explorer. This is a course where an introduction to the modern study of dynamical systems, the interdisciplinary field of applied mathematics that studies systems that change over time is given.
Attending the first lectures was great, I learned a lot and also, it was easy. But the difficult part begins at chapter 2. I had to watch all the videos of chapter 2 more than 2 times to understand. And I had to do my own research on some topics. After all of this, I was to tired and needed a break And went for a walk.
During the walk, I took this photo.
