Scientists:
Tsung-Dao Lee (李政道) and Chen-Ning Yang (杨振宁) shared the 1957 Nobel Prize on their parity violation work [T. D. Lee and C. N. Yang, Phys. Rev. 104, 254 (1956)], which also opened the door to the studies of mirror symmetry.
Edward W. Kolb is a great cosmologist and his early work on mirror matter has fully turned my attention to mirror matter theory. The beautiful picture about mirror-matter in the early Universe is strikingly presented in his Nature paper [E. W. Kolb, D. Seckel, and M. S. Turner, Nature 314, 415 (1985)]; I leaned a lot from his classic textbook “the early universe” with M.S. Turner.
