圣经我读的不多，更谈不上感悟。本来是觉得小沙的帖有趣而跟了几句，没曾想竟引来
丝竹空这样认真的一篇，实属意外收获， 谢谢！
看来丝竹空是学物理的，那我就在中微子上多言几句。中微子的质量测定 is a subject
of current research。Indeed，they were believed to be massless for a long time. But the recent results indicate that they have finite mass. Different
neutrinos have different masses, for instance, the electron neutrino is the
lightest, with the mass on the order of ~1eV. Since neutrinos are so light and
charge neutral, it is difficult to measure their values experimentally. There
are predictions so far on the upper limits of the neutrino mass but not on the
accurate values yet. Of course, this has significant implications, for the universe is full of neutrinos.
本来不确定丝竹空是否是我已经打过招呼的人的新衣服，现在看来还真是第一次交谈，
并且我有似曾相识的感觉。：）那就再郑重地问声好（非指名字：））。希望以后能在
共同感兴趣的话题上多交流。
