FSC stands for the Fine Structure Constant. It is a dimensionless physical constant that characterizes the strength of the electromagnetic interaction between elementary charged particles. The fine structure constant, denoted as FSC, is approximately 1/137. It frequently appears in quantum mechanics. Deviation from this value would render the formation of the universe and life impossible. "精细结构常数 FSC (fine structure constant),1/137,量子力学多次出现,偏离该值,宇宙和生命无法形成 |
