李老师 explanation has some conceptual mistakes. Historically, Einstein has derived E = mc2 *seven* times, but all have mistakes. Max von Laue's (1911) derivation is better.

李老师没在视频里个别推导 E=pc 这公式,因为这基础公式已经涵盖在更基本的公式里了: 1. 功 (能量): work done (E) = force (F) x distance (s) 2. 牛顿第二定律: force = rate of change of momentum F = p/t 代入,就得到光子能量: E = (p/t)s = p(s/t) = pc
