Tech Central Station is full of goodies today, including this article from Jennifer Zambone on experimental economics, Arnold Kling on investing and the margin of safety, and Jim Glassman on investing in the “Nifty 50″. Very interesting. OK, I’m off to teach.

Okay, I admit it, I’m a gearhead. Tools, gadgets, all very cool. Energy industries are chock full of really cool technology, as indicated in this Globe and Mail article about 3-dimensional computer imaging of potential drilling sites, based on seismic data. Such technology enables the petroleum engineer to survey the plot from Calgary instead of having to schlep to the far, chilly corners of Canada. Very cool.
