TANTALUM MEA CULPA

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!"
