The Space perspective with Jeffrey Hoffman (besides having flown 5 times in the Shuttle, he is also an astrophysicist and MIT professor, the photo is actually him repairing the Hubble)

Economic rationales for space activities, with Cohendet (world-renown economist, professor in Strasbourg and Montreal)

I like the way we take notes: no paper (save trees!!), but writable PDF files (thanks Jorge for Acrobat 7.0)
