I am writing my phd dissertation in a technical field and I have a question. When in the same chapter, I finish a section and want to connect it with the next section I am not sure what is better. Lets see an example:
Chapter: "Popular Vehicles"
A bus was very popular and cheap... Everybody loved it! However, new production techniques, robotics, whatever and an economic revolution allowed every one to own a car.
A car offers convenient transportation...
Indeed, I don't like to finish the first section without a rational ending by just saying "and then buses were replaced by cars" and finish the section. However, I am afraid I am losing relevant information regarding the "Car" which should go in that section, and I don't want to repeat that information in the next section. If you are reading everything it should be okay, but if you just open the book, go to the section "Car" because you care only about it and read that part, you have missed important information regarding the birth of cars!
In short, I am doubting whether a sentence should be a conclusion of a section, or an introduction of the next. So, what would you think is the best approach to technical writing?
