Linus Pauling: I like thinking and for some reason it pleases me to feel that I have a thought that no one else has ever had before. Sometimes these thoughts aren't especially important ones. I ran across a rare mineral called sulvanite, a copper vanadium sulfur, which is found in very few places in the world. I went to Washington, D.C. to the Geological Survey and met a man, a geologist, a mineralogist, who had a small sample, a few crystals of this rare mineral, sulvanite. It had been, well I was able to get these from him and, practically the world's supply. For a while, I carried them around with me feeling pleased that I had this supply. Then, when, with one of my students I determined the structure of sulvanite. The structure turned out to be quite different from what I had predicted for it. For the first time, a sulfur atom, instead of directing its four bonds toward the corners of a regular tetrahedron, the way the carbon atom does in diamond and methane and most carbon compounds, it directed three bonds in three of these directions and the fourth one in the backward direction, right in between these three. This was an astounding discovery and I was pleased to think for a while now nobody knows, nobody else in the world knows that there is this odd sort of sulfur atom in the world.
