This is an incredible story of how a 14-year-old boy from Malawi who had to drop out of school was able to generate electricity and eventually change his whole family’s and villages situation by building a windmill on his own out of garbage and scrap: http://www.wired.com/wiredscience/2009/10/kamwamba-windmill/.
His initial desire was to be able to have light for him to use at night after the sun has gone down. Now it has developed in to much more than that.
Here’s an interesting, nice graphic showing the history of the International Space Station and how it has grown/evolved over the years.
Fascinating video about an experiment they did with the Hubble telescope. They pointed the telescope in to a dark, empty part of space about the size of a small grain 0f sand and then left the lens open for 10+ days. This video shows and talks about what they found. In that incredibly small window they found tens of thousands of galaxies each of which contains hundreds of billions of stars. It really gives a glimpse of a perspective of how big and infinite the universe is.
An interesting interactive graphic from the NY Times of how different groups of people spend their time. Link
Can you imagine their thoughts as they exited this plane?
