Glenn Reynolds comments on the Ayres and Donohue's letter on the coding errors.
Reynolds also states that he is reluctant to believe charges of dishonesty against Lott because some critics have made ad hominem charges against him, for example, that his research was funded by ammunition manufacturers. However, his academic critics never made such charges. I specifically noted that the funded-by-ammunition-manufacturers charge was an ad hominem as recently as a few days ago and wrote generally about other unfair attacks on Lott years ago.

Ion-exchange resins are surprisingly simple things - here's the idea: just about everything that has a charge has to have an opposite charge around somewhere. Ususally, charged things float around willy-nilly in solution (your Na+ and Cl- in your salt, for example).
In our examination of the first of Maxwell's four equations, we saw that magnetic charge doesn't exist as far as we can tell. On the other hand, electric charge permeates every aspect of our existence.
