What conjures up in your thoughts when you think of an email? What factors into the length of time it takes to send an email from one place to another? Keep a diary to jog your memory of significant events and details. Where do they diverge from one another? Do you know the level of detail (or abstractness) that each model has?

When you think of email, what kinds of images come to mind for you? When an email is sent, what precisely takes on behind the scenes? Create a list that includes all of the information that you have found up to this point. Does anybody have any idea what the underlying factors that led to these inequalities are? Does your model perform effectively when subjected to varied degrees of complexity?

What types of mental pictures come to mind for you when I say "email?" Where does an email really go after it's been sent? Write down anything you can think of that fits this description. Does anybody understand the background of these variations, and if so, could you please explain them to me? Do your models all depict equally complicated scenarios?

When you think of an email, what comes to mind? The origin and destination of an email are the same place. Take notes on your research. Let's start with the obvious question: what's the deal with all the variations? Take note of how the degree of model detail (or abstraction) varies.
