Mark (Henschel), The American Society for Nondestructive Testing (ASNT) is publishing a new industry Handbook; Aerospace NDT.
The editor at Boeing in Seattle is Dr. Richard H. Bossi. The editor at ASNT is Patrick O. Moore, who sometimes contributes to this USMA list. Patrick has invited me to verify the conversions to SI Units of Measurement in draft Chapters of Aerospace NDT. You will be pleased to know that numbers + units are expressed *first* in SI, and second in units outside the SI! There are some problems with this "duality"; e.g. three significant digits increasing to four digits of implied precision, and graphs with only unit markers outside the SI. Is "duality" a problem in recent issues of Popular Science? Which issue did you examine? Which issue did Mike examine?

Where do you see the metric units? The whole thing was in inch pound. They even used pounds when they should have used tons. I remember writing letters to Popular Science years ago asking them to use SI, and I was hoping you were right. Sadly, even magazines like "The Futurist" still uses inch pound. One would think we would use SI in the future, right? Years ago back I even got a response from an editor at Discovery Magazine, who was convinced Discovery would gradually move into a metric future. But that never happened either. Wish I could see more metric usage in science and technology magazines. About the only thing that's metric is the cigarette ads, back when they advertised cigarettes. They were advertised as 100 millimeters long. When I was in Canada, all the weather reports were metric, and they even pronounced kilometer correctly. A bit of hope for a metric advocate since all of that happened in my lifetime.
