13 Thus the priest shall make atonement for him for the sin which he has committed in any one of these things, and he shall be forgiven. And the remainder shall be for the priest, as in the grain offering.
Laws for Guilt Offerings
14 The Lord spoke to Moses, saying, 15 “If anyone commits a breach of faith and sins unintentionally in any of the holy things of the Lord, he shall bring to the Lord as his compensation, a ram without blemish out of the flock, valued in silver shekels, according to the shekel of the sanctuary, for a guilt offering. https://t.cn/RJZk0ky

世间万物，不过是一堆response罢了。
无论是电流也好，能带也好，Chern number也罢，不过是这一个个响应的输出与特征
从量子力学S矩阵到量子场论Feynman格林函数
从kubo定律到拓扑能带First Chern number
不过是一个个响应游戏罢了
唯一的不同只是换了个toy background
从连续系统到离散格点
从单粒子到多粒子集体行为
从T²到S²，从Wilson loop到winding number
从pump到QSH，从interaction到FQH
从Chern-Simons到anyon exciting
道生一，一生二，二生三，三生万物
众生之下，皆是无趣
无趣！无趣！无趣！ https://t.cn/z86Jjg8
