今天一早打开信箱，见到中微子实验家曹俊研究员发来的消息，题目是“中微子也过周末”，介绍了一篇L.E. Bergman的预印本，十分有趣。下面引用有关的信息：

A Weekly Pattern from Hourly Estimates of the Super-Kamiokande-I Neutrino Flux 1996-2001

h for a neutrino flux difference between weekdays and weekend days, for the average week of the Super-Kamiokande-I (SK-I) Experiment, was undertaken using the 5-day period version of the SK-I data taken from May 31st, 1996 to July 15th, 2001. A significant (p << 0.001) difference was found and the most obvious neutrino flux change from weekdays to weekend days can be summarized as follows: Some neutrinos took the weekend off, especially on Saturday.
