Here is a copy of the e-mail I just sent to physorg.com. Let's see if it gets any attention (and maybe even a response). Ezra
========= Dear PhysOrg: I noted with interest an article on how scientists were able to observe the hydrogen bond exchange that you have published on your web site. While the article was quite fascinating, I was disappointed to note that you were still using the non-SI unit "angstrom" in your story. Isn't it time, now that we have entered the 21st century, to abandon old ways (no matter how traditional or well-worn) and replace "angstroms" with nanometers, particularly since the use of the angstrom is officially discouraged by both the International Committee for Weights and Measures and the American National Standard for Metric Practice? Thank you for your thoughtful consideration of this matter. Sincerely, Ezra Steinberg Technical Writer Kirkland WA
