Some additional interesting links:

• Another example of emergent universal behavior, as it is demonstrated that runners at the start of a marathon seem to collectively obey hydrodynamics, like a fluid.
• The Voices of the Manhattan Project oral histories effort has a large number of interviews online.  It’s important for posterity that these were recorded before everyone involved is gone.
• Maybe massive open online courses were not, in fact, the end of the traditional model of higher education.  Who could have foreseen this?
• There are people arguing that the preprint arxiv model is a good path toward opens access.  This is definitely something I like, especially more than models involving authors paying thousands of dollars to for-profit publishers for open access journals.
