In this episode, Angela learns about seven big ideas that help explain how people, animals, computers, and even the world change over time. She learns that things can grow while still staying themselves, that hidden problems can build up before something breaks, and that memories and past choices can change what happens next. Some lessons are about how we see only part of the world, how systems connect together, and how broken things can sometimes heal and recover. Using simple stories and examples, these ideas help explain thinking, feelings, learning, friendship, faith, science, and why everything in life is more connected than it first seems.
