We often think of scientific ideas, such as Darwin’s theory of evolution, as fixed notions that are accepted as finished. In fact, Darwin’s On the Origin of Species evolved over the course of several editions he wrote, edited, and updated during his lifetime. The first English edition was approximately 150,000 words and the sixth is a much larger 190,000 words. In the changes are refinements and shifts in ideas — whether increasing the weight of a statement, adding details, or even a change in the idea itself.

On the Origin of Species: The Preservation of Favoured Traces is a visualization of the edits Darwin made to the book over the course of six editions. This was created with Processing, something I’ve been meaning to try out. via Pharyngula

Just Landed

Posted by Shannon

This got me thinking about the data that is hidden in various social network information streams - Facebook & Twitter updates in particular. People share a lot of information in their tweets - some of it shared intentionally, and some of it which could be uncovered with some rudimentary searching. I wondered if it would be possible to extract travel information from people’s public Twitter streams by searching for the term ‘Just landed in…’.
