……跑到客厅，按着我伴侣（完全不懂数学物理）听我即兴讲了 15 分钟，还用了好几种颜色的墨水画图。她倒是没觉得有多惊艳。（Fleisch 的《Student's Guide to Waves》也强烈推荐，要是我当学生那会儿有这本书就好了）。
…to the living room and subjected my partner (not a math or physics person at all) to an impromptu fifteen minute lecture with diagrams in multiple colors of ink. She wasn't as impressed. (Fleisch's "Student's Guide to Waves" is also highly recommended as a book I wish I'd had when I was a student).
题外话——看看《A Student's Guide to Waves》，这是一本我成年后才啃完的数学书，非常棒 https://www.danfleisch.com/sgw/ https://www.amazon.com/Students-Guide-Waves-Guides/dp/110764...
Offtopic - check out A Student's Guide to Waves, a math book I just worked through as an adult which is awesome https://www.danfleisch.com/sgw/ https://www.amazon.com/Students-Guide-Waves-Guides/dp/110764...
