My design of a bus schedule and route combines a graphical timetable with a route map overlaid on a precisely
detailed aerial photograph, so much richer than the typical schematic diagram of bus routes. Hourly, daily, and
weekly rhythms of the buses are clearly revealed, as well as details of each journey. During rush hours, lines
densely crowd into spaghetti—but then service is so frequent that the jumble of lines informs the rider simply to
show up, for there will be virtually no wait for whatever bus it is that arrives. The gray grid is set at ten-minute
intervals in order to ease visual interpolation of the times of arrival. The aerial photograph unveils the area mostly
at the level of house resolution, that is, with sufficiently fine details to show individual buildings. Indeed, the
reaction of those who live in the area is to explore the photograph, personalizing the data, seeking to discover their
own residence, school, or workplace. Same picture, but many stories. -- Edward Tufte
In the video below, I explain several methods for comparing fractions. When comparing two fractions, there are three methods that sometimes work:
- If the denominators are the same, compare the amount of pieces
- If the numerators are the same, think of the size of the parts.
- Sometimes you can easily compare to 1/2
If none of those "work", you can always convert the two fractions so they have the same denominator, and then compare.
Sometimes it is easy to know which fraction is the greater of the two. Study the examples below! 7
At the end of their book,  Hallin and Mancini discuss the convergence- or homogenization-thesis. The basis for their argument is their observation of several transformation processes that take place especially in Europe. The most important processes are the European integration , politically as well as with regards to the media (. European media laws ), the decline of traditional political mass parties , the American influence on the professionalization of journalism , and finally the commercialization of the media markets in Europe. These are the main reasons why Hallin and Mancini conclude, that the European countries might be pushed toward the Liberal model . They even go one step further and hypothesize that the core forces of that homogenization- or convergence-process might be valid for other parts of the world. However, they point out that there might be limitations to this process as well because the elements of the process are anchored in the structural differences between the political systems around the world.
