Visual change suggestion to Graphic used in Chapter 3

Hi Chris, Just a suggestion on a change to one of the presentations you use in your Crash Course (Chapter 3 - Exponential growth). In the 'Population Growth Example' (time reference 4:04) your graph shows speeding up by using a down arrow. I find this distracting as people normally associate growth with an upwards arrow/trend. Perhaps you might want to consider reversing the table contents to list the growth occurring the other way so that the growth arrow and smaller numbers starts from the bottom and heads upwards - this way it doesn't cause a momentary distraction while people readjust to thinking about growth being listed downwards instead of upwards. Yes - logically it doesn't matter but it is a momentary readjustment never-the-less and causes a break in a person's concentration (at least it did me). My 2c worth... :-)
