This week we had a fun physics colloquium given by Paul Canfield of Ames Lab and Iowa State University. He spoke about the discovery and characterization of new materials, with a particular emphasis on heavy fermion compounds, but with a significant discussion of MgB2 as well. His main purpose was to convey how physicists like him think and approach problems, and I think he succeeded. He also had a funny slide called "Periodic Table According to Most Physicists" that looked roughly like this:
H H' (almost like hydrogen)
H'' H''' C H'''' H'''''
Elements that may not even be real
