About

Retired physical chemist, physicist, book author, user-interface researcher, software engineer.

Oh hey, I found myself on Wikipedia by accident one day: Barton–Nackman trick!

Just in case:

• I am the coauthor of Barton, J. J., & Nackman, L. R. (1994). Scientific and Engineering C++ an Introduction with Advanced Techniques and Examples. Addison-Wesley Longman Publishing Co., Inc.

• I have two highly cited papers in Physical Review Letters:
  • Barton, J. J. (1988). Photoelectron holography. Physical review letters, 61(12), 1356 and
  • Barton, J. J. (1991). Removing multiple scattering and twin images from holographic images. Physical review letters, 67(22), 3106.
• My PhD in Chemistry from UC Berkeley was about half theory of electron scattering from atoms in surfaces. See^[1] for a peer-reviewed summary.
• My master's degree in Applied Physics from Caltech applied quantum chemistry to the surface structure of gallium-arsenide

Experience with Templates

The template system is very irregular and confusing:

• The regular expressions are non-standard and limited.
• The string matching occurs on parsed wikitext, so you can't base patterns on reading wikitext.
• some tags, esp. <ref> tags are magic and cannot be processed by template code.
• many existing templates really only support special cases, eg {{Plain text}}

Experience with Wikipedia

I really enjoy learning about new topics by editing wikipedia.

Some things are less fun. An effort was made by an editor ban me from editing "his" articles. Disheartening.
