Light, heavy light, and asymmetry

Liang Han (U.S.T.C., Hefei, China), Chen Wang and Yifan Xiang (undergraduates at U.S.T.C.) and Siqi Yang (U.S.T.C. and now at U. of Iowa) are the primary analysts for this measurement.

The “Cosmic Frontier”

Perhaps that is one of those “duh!” questions. After all, humans have wondered about the cosmos for all of recorded history and no doubt long before writing was invented. But there is a modern component to this query., by Don Lincoln.
