About the 近现代物理与相对论专业级 certification
一项专业级认证，带你从牛顿的经典世界走入二十世纪与二十一世纪的物理学前沿。你将从狭义相对论起步：爱因斯坦的两条公设、同时性的相对性、时间膨胀与长度收缩、洛伦兹变换、相对论速度叠加、相对论动量与能量，以及科学史上最著名的方程式E=mc²——还有所有观测者都认可的时空间隔和相对论多普勒效应。随后你将从概念层面理解广义相对论：等效原理、弯曲时空、引力时间膨胀、光的偏折、黑洞与引力波。课程随后转向原子与核物理——原子模型、核结构、结合能与驱动裂变和聚变的曲线、放射性（α、β、γ衰变）、指数衰变定律与半衰期，以及核反应。从这里你将纵览粒子物理——标准模型、夸克与轻子、四种基本力及其载力子、反物质、希格斯机制，以及支配每次相互作用的守恒定律。凝聚态物理（能带理论、半导体、超导）与宇宙学（大爆炸、哈勃定律、宇宙膨胀、暗物质与暗能量、宇宙微波背景辐射）的专题内容完善了现代物理图景，同时涵盖激光背后的波动光学与光子概念。全程每一个公式都以平实的语言陈述，并通过具体数值加以演算——洛伦兹因子、能量释放、衰变份额——使你学完后能够真正计算，而不仅仅是背诵。这是从经典力学通向物理学前沿的桥梁。
