Edward Soja was a very smart person who studied cities and how they work. Just like how you might take apart a toy to understand how it works, Edward Soja looked at cities to see how they were put together.
He was interested in how people moved around and how different parts of the city connected with each other. He also looked at things like how the buildings in the city were built, who lived in which parts of the city, and how people from different communities interacted with each other.
Overall, Edward Soja was really good at understanding how cities worked and how people lived in them. He wrote many books and taught a lot of students so that they too could understand cities better.
