Our brains are organized through networks of related concepts, stories, or the overall perception of a topic. When you learn a new fact, it gets embedded in a nest of everything else you know. The tighter the connections, the better you will remember and recall the information.
If you want to remember facts better, create a little contextual nest for your new fact to live in: Read some background. Consider what you've just read. Think about the terms you already know. Write it down or draw little images.
