内容简介
"用细线把胡萝卜水平吊起，从细线的位置切断胡萝卜，两边的重量会发生什么变化？"这是一个关于杠杆与平衡的问题。杠杆可以将很小的力放大。
我们四周有很多利用杠杆原理的东西，例如，剪刀、开瓶器、螺丝刀、门把手、自来水水龙头、自行车或汽车的车把和转向盘等。这些现象都与物理法则密切相关，即使物体产生转动趋势（力矩）的平衡。
本书以猜谜的形式为出发点。每篇开头都会抛出与前文类似的小问题，让大家一边思考一边阅读。相信大家会惊讶地发现"原来这里也有物理法则"，在不知不觉中加深对物理知识的理解。
本书涉及的物理以"物理学"为基础。相信大家都知道物理学是自然科学（以下称为"科学"）的一种。物理学的研究对象小到基本粒子、原子，大到宇宙，自然界的一切都属于物理学的研究范畴。
物体及其运动属于自然界的共通法则，而物理学旨在探究这些自然界最根本的法则。
学校会教学生物理、化学、生物、地理这四门理科学科，其中物理是抽象度最高的学科，许多人都对此感到非常头疼。确实，力学、能量、波、电磁学等都非常抽象，不易理解，每个知识点都难以用一般的方法掌握。
本书的内容聚焦初中、小学物理，主要介绍中小学理科的物理知识。
每章的划分也以中小学物理为依据。书中没有一下子讲到高中物理知识，而是通过巩固小学、中学的物理要点，即物理的基础、基本知识，循序渐进地进行讲解，通过这种方法，我们可以有效进入下一阶段的学习。
就像书名一样，本书采取猜谜、谜题的方法来说明。这也是根据我教理科课程总结出来的方法，"提出问题，确认问题"→"写下设想·自己的思考"→"讨论" → " 根据讨论， 写出经过深思熟虑得到的答案"→"通过实验和观察确认答案"→"写下实验及观察确定的答案"→"备注：具有延展性的问题、实验、科学词语、补充说明文字"。
这本书的精华是在一定时间内弄懂各个谜题，并体会谜题带来的趣味性。课程围绕解开谜题展开。在科研中，我们经常把"疑问"以"问题"的形式提出，进而探究问题。
请尽情享受"有趣得让人睡不着的物理"世界吧！
