书籍介绍
当CS背景的人越来越习惯把工程师当作'查文档的工具人'，这本小书却固执地提醒：真正能扛住问题的，是脑子里那套化简问题的能力。作者Ashby提出'乐高工程'——六条必须烂熟于心、能在脑中快速估算的基本规则，如同积木，拼对了，复杂问题便自行低头。它不追求公式的严密推导，而追求'量纲直觉'：从'电压*电流=功率'到'电感=(电压·时间)/电流'，把看似无关的物理量用同一套手感串起来。读者最在意的，正是这种'被遗忘的基本功'的重新拾起，以及书末'做人做事的道理'那份难得的工程师自省。适合想重建电子学整体直觉、或厌倦了碎片化查资料的人。
作者简介

精彩摘录
- "Cool application note: using two transistors to switch a signal level Vcc PNP switched by NPN."
- "电压*电流=功率 阻尼系数=阻尼力/速度"
- "电阻=电压/电流 质量=(力*时间)/速度 电感=(电压*时间)/电流"
- "“Lego” Engineering You can always look up the more advanced stuff, but most of the time a solid application of the basics will force the problem at hand to submit to your engineering prowess. These six rules are things that you should memorize, understand, and be able to do approximations of in your"
- "Thumb Rules ■ Electricity is fundamentally charges, both positive and negative. ■ Energy is work. ■ There are just as many positive as negative charges in both a conductor and an insulator. ■ In a good conductor, the electrons move easily, like liquid water. ■ In a good insulator, the electrons are "
- "Voltage generates an electrostatic field (it is this field repelling or attracting other charges that creates the voltage “pressure” in the conductor). Current or flow or movement of the charges generates a magnetic field around the conductor."
- "The charges in the wire are moving much more slowly than one might think. In fact, DC current moves at about 8CM per hour. (In a typical wire that is, the exact speed depends on several factors, but it is much slower than you might think.)"
- "Thumb Rules ■ An accumulation of charges is what we call voltage. ■ Movement of charges is what we call current or amperage. ■ Energy is work; in a circuit the electromagnetic effects move energy from one point to another."

嗯……好像对于外行来说还是难了点…
简要介绍入门知识 可以看看作为了解 科普性质大于教学性质 新手推荐读一读
不错的EE入门书籍，浅显易懂
用积木构建王国
扫了一眼目录，撑死大二看完。167页开始看完了最后部分
比教科书好看很多
没有另外的两本日本人写的书好懂🤔标记一下
最后的人生箴言部分也值得一看.正文部分难度曲线不太合理,可以挑着看.
配合b站麻省理工公开课《电路与电子学》共同食用
