Historical Collection Home. Chemistry: All About You! AstroEDU. Neil deGrasse Tyson Explains The Origins Of Atomic Elements In Our Bodies. What's the human body made of? Ninety-nine percent consists of atoms of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus, with the remaining one percent consisting of trace elements like magnesium, sulfur, and iron. But where did those elements come from? That question long presented a puzzle to scientists. At least it did until the publication of a now-obscure scientific paper in the middle of the twentieth century, as celebrated astrophysicist Neil deGrasse Tyson explains in a new video (above). "There was a seminal paper -- one of the most important research papers ever published -- that gave us the description of the origin of the elements," Tyson says in the video.

The paper is entitled "Synthesis of the Elements in Stars" but is sometimes referred to as the B2FH paper, after the authors' initials. It was published in Reviews of Modern Physics in 1957. So where did the heavy elements found in nature come from? Related on HuffPost: 500 experimente la tine acasă - episodul 1.
