The article on brain tingles, seem very interesting. The detail of whether it serves and evolutionary purpose seems that evolution had evolved from being the subject of skepticism to a necessary dogma. I actually experience the related feeling of music induced fissles or some word similar to that. This is when there is a key change. I read with interest the article trying to reason its way about the impossibility of the amount of earths water. It is refreshing to have something authored by a scientist rather than a science journalist. In the latter you look for the quote to come up in around paragraph 5 and the structure is so formulaic. This I feel didn't cut through to the different types of isotopes in water, and what the meaning is. I felt the major possibility is that the impact on of Thea carried a large amount of water. The last word on recycle battery dump spontaneous shorting wasn't very challenging. I also didn't get that much out of the discussion of the adhesion of water. I did find the letter on intellectual contamination of knotting culture and incredible left field wake up call in examining these ideas.
