Be Nice to Geologists Well, I have been taken to the woodshed by my many geologist friends for using the word “geologist” to describe those who use the Periodic Table to guide their expectations, which in turn are key to deciding whether or not a result is viewed as “extraordinary”, in the Sagan sense. My bad. And to think of it, more correct for such folks would be the word “chemist”. A Tempting Science
Unsociable methane comes in from the cold - physics-math - 13 May 2011 An abundant but stand-offish carbon-based molecule has been coaxed into playing nice. Chemists have devised a way to persuade methane to react with other molecules under gentle conditions, making it vastly more useful as a building block for synthesising more complex organic chemicals. Methane molecules are composed of a single carbon atom connected to four hydrogens. This means methane is the simplest of all the hydrocarbons that contain only simple carbon-hydrogen (C-H) bonds. To form a bond with another molecule or atom, at least one of these C-H bonds must break.
