• Following up on the recent exchange about the metal
  tantalum, Alan Luedeking writes: "My apologies -- Mr.
  Schmidt is right of course; moreover, I was wrong about
  the conductivity of tantalum altogether: While it is quite
  conductive, it is less conductive than both silver and gold,
  having a thermal conductivity of 57.5 J/m-sec-deg and
  an electrical conductivity of 80.321 1/mohm-cm.
  

  Silver and gold both have significantly higher values. For
  more information on all aspects of elements I recommend
  the following interesting website:
  http://www.scescape.net/~woods/elements/.
  I apologize to all for my misinformation!"
