The wonderful thing about this talk that I found blog-post worthy was the fact that the topic it is on is something that I have always found incredibly tedious, as is the case with most people I think and yet I found myself clued to the screen listening to Garik Israelian talk, feeling my sphere of understanding expanding by leaps and bounds.  It really opened my mind up to the potential of what we can learn and the incredible exploration that is going on in our universe.
