Six More Elegantly Explained Concepts
on April 4, 2003
Six Not-So-Easy Pieces is the sequel to the book Six Easy Pieces. The first book is a collection of six of the easier lectures from Feynman's freshman and sophomore physics classes at CalTech. Six Not-So-Easy Pieces are some of the more difficult lectures from those classes. In contrast to the first book, these lessons are much more mathematical. Freshman calculus is definitely a prerequisite to reading this book. Courses in vector calculus and differential equations will help the reader to more completely understand the works, but they are not absolutely necessary. However, without much mathematical knowledge, one can just take Feynman at his word for all the equations, reading mainly the conceptual explanations, but one will invariably miss out on some of the points. For anyone reading the book, Feynman's teaching style is something that can be enjoyed. He explains the concepts in a comprehensive and not-too-difficult manner and seems to have a full understanding of what the student in the lecture hall is thinking. The six topics (chapters) covered in this book are: Vectors, Symmetry in Physical Laws, The Special Theory of Relativity, Relativistic Energy and Motion, Space-Time, and Curved Space. This book is in no way a survey of physics. It is more of a sampling of Feynman's teaching. However, the common thread that runs through the six pieces is that they all relate to understanding relativity. For the layman who has a mathematical background and wants to understand the concept of relativity, this book is an excellent help. I would suggest reading Six Easy Pieces before reading this book, but it is not necessary. If you enjoyed reading the first book, I would highly recommend this one and vice versa.
