BBC has a bunch of pictures by Michael Markieta, visualizing all the flights around the world.  More on this can be seen at Spatial Analysis. 

Tallest Buildings

Council on Tall Buildings and Urban Habitat (who would have known?) has a nice page that lists the tallest buildings as per floors/overall height, and has a bunch of interesting info about large buildings. 

Online Education

Lot of chatter about online education, what some people are doing, and some suggestions on where we might be going.  (and some old points)

• Innovation Hub interviews Sal Khan
• TED Talk by Sugata Mitra about how people can learn on their own (also NPR writeup on this)
• Unstoppable Learning: TED Radio Hour shows on new ways of thinking of education.
• Is Massively Open Online Education a Threat of a Blessing (npr)
