Sunita Williams, Space Station Commander, Provides Video Tour of Orbital Laboratory

In her final days as Commander of the International Space Station, Sunita Williams of NASA recorded an extensive tour of the orbital laboratory.

This video is incredibly interesting, but something very noticeable, to me, is that this woman, Sunita, has got what I can only describe as the perfect voice and also the perfect way of talking. The very exact pause, the very exact timing between two words, at least its average, or distribution, is absolutely perfect. In fact there is even something else in her voice, that I can feel, that I have always associated to intelligence, but I don't know how to call it or describe it, I just know it's there. It's very rare for me to observe it, and most of the time I observe it's with university teachers. I always notice it when I hear it, but again I don't have a name for it.

[update] Thinking of it..., I think I have a way to sort of describe it. She is intellectually happy; and in humans, when this happens, because it filters out in their speech patterns in a very particular way, I can hear it. Intellectual happiness ("Intellectual happiness" is probably a temporary name before I find something better), is very rare because it is difficult to achieve. Knowledge and understanding, first of all, is not accessible to everybody, one needs to have solved basic survival problems that some are still struggling with. Then, our standard schooling system, which is the way most kids in the developed world and some developing countries access to knowledge, does nothing else than giving them a very insane relationship to knowledge and understanding. (I read yesterday news of a bunch of Chinese female school students who jumped to their death because they had too much homework, and don't even get me started on the South Korean kids killing themselves for as little as a bad marking...). Thinking of relationship to knowledge, I have never ever heard intellectual happiness in any religious believer I have ever met in my life.
