内容说明 About the content
本书是科普读物，用来帮助理解技术的原理和历史，不构成工程、医疗、法律或投资建议。App 里的互动实验是简化的教学模型（比如疫苗实验用的是虚构的疾病，链式反应实验是概念演示），数字只用来说明道理，不能用于实际设计、诊断或决策。
This is a popular-science book meant to explain how technologies work and where they came from. It is not engineering, medical, legal or investment advice. The interactive labs are simplified teaching models (the vaccine lab uses a fictional disease, the chain-reaction lab is a conceptual demo); their numbers illustrate ideas and must not be used for real design, diagnosis or decisions.
