The Histomap, created in 1931 by John B. Sparks, attempts to distill all of human history up to that point into a single image:
The chart emphasizes domination, using color to show how the power of various “peoples” (a quasi-racial understanding of the nature of human groups, quite popular at the time) evolved throughout history.

The infographic above shows how big a city would have to be to house the entirety of the worlds population if they lived like the residents of various cities, using the continental United States for scale. Its author, Tim de Chant, considered only the geographical space taken up by the residents and not the land required to provide them with resources like food and water in this particular graphic. He has, however, investigated these other factors as well:
What’s missing from it is the land that it takes to support such a city. In articles and comments about my infographic, some people overlooked that aspect—either mistakenly or intentionally. They shouldn’t have. Cities’ land requirements far outstrip their immediate physical footprints. They include everything from farmland to transportation networks to forests and open space that recharge fresh water sources like rivers and aquifers. And more. Just looking at a city’s geographic extents ignores its more important ecological footprint. How much land would we really need if everyone lived like New Yorkers versus Houstonians?
It turns out that question is maddeningly difficult to answer. While some cities track resource use, most don’t. Of those that do, methodologies vary city to city, making comparisons nearly impossible. Plus, cities in most developed nations still use a shocking amount of resources, regardless of whether they are as dense as New York or as sprawling as Houston. Any comparison of the cities in my original infographic would be an exercise in futility at this point.

After the jump, a really cool infographic that shows the tremendous distance from the highest mountain peaks to the deepest sea trenches. (Get ready to scroll down a LOT).
Great video that explains the financial crisis in a more comprehensible fashion. Part 2 is below.

This is a really cool chart by Dan Meth. Dan says:
No one really pays much attention to what year sci-fi movies take place. I thought it would be interesting to arrange some classic films about the future into chronological order and see what we’d find. I’ve also charted the years in which they were released as well as the current year. This is by far the geekiest thing I’ve ever done.
