A Window on Physics

“It’s No Small Matter” (Dec. 20), your Column One article, always a treat, was especially good this time. It has managed to make the search for the sterile neutrino quite understandable to us who know no physics -- not to mention quite human (even comic), heroic in its tedious progress and somehow beautiful as well. Thank you for publishing challenging concepts quite lucidly explained.
