What Do Abraham Lincoln and the pH Electrode Have in Common?
Not a lot, you say. Well, you would be wrong. Last week Mr. Lincoln celebrated his 200th birthday. (More accurately, we remember his 200th birthday and reflected a lot on his legacy.) At the same time, in our February issue, Greg McMillan and Stan Weiner reminded us that this is the 100th anniversary of the invention of the glass pH electrode in their Control Talk column.
Greg and Stan may not be great Lincoln scholars, but they are the Carl Sandburg of all matters control. Their trilogy on pH electrodes began in February with Part 1 of the Secret Life of Electrodes. Part 2 is already in production for the March issue, and they'll be wrapping up the saga in May. Don't miss the next exciting episode.
