alt Hacker NewsOften the most straightforward way to walk through an idea while teaching it is not the same order that the ideas were developed, and might not even use the same set of ideas in building up to it, so it can be tricky to get both the best explanation of the idea and the historical context in at the same time without making things more confusing.
I like to see ideas presented as the evolved. Each solution is developed as a perceived reaction to the shortcomings of the previous. This becomes a contrast and comparison as to why one idea is appropriate for a particular context.
