Six Not-So-Easy Pieces: Einstein's Relativity, Symmetry, and Space-Time

This is a great introduction to 20th century physics, which is still very much relevant today.

Great book - made me realise how rusty my maths had become but worth persevering with. As the book suggests, I would highly recommend searching online for a few videos of Feynman in action. An awesome and inspiring man to listen to. It made the book a real joy to read afterwards.

I first encountered this series of books, written by Richard P Feynman, in my local book retailer and I was surprised at their size. Despite the nature of their subject, they are barely a couple hundred pages in length. Usually scientific books are much thicker volumes. But when one realises these books were written from notes derived for student presentations by Feynman, then size doesn't really matter. I am more inclined to purchase a 'thin' book than a 'thick' book because apart from being cheaper to buy and easier to carry, it should be an easier book to read. Doubtless, size is a marketing ploy but it means these books are affordable to a great many more people. The information these books contain, often illustrated by original drawings by the author, help to convey some quite complex theories. These theories maybe right or they maybe wrong but they serve to illustrate the thoughts of a 'genius' whom many professionals believe rivalled Einstein in terms of his vision of how the universe works. Feynman was a controversial, colourful, some say eccentric theoretical physicist who cared little for convention and left an indelible mark in understanding science. I purchased 3 books in this series and I purchased 3 more for a friend's birthday. Doubtless I will purchase other books in the same series when I have time to read them.

'Easier' than companion book. Great to start but maths beyond me.

Covers some of the more difficult concepts in physics

Very good read even for those without a physics or maths background. He's able to take, what for most people, are incomprehensible concepts and ideas and explain them in a manner that even a numpty like me can understand. I recommend this book to anyone interested in physics as it gives an insight into the concepts of how the universe works on both the large and very small scales.

The book is great but it arrived with no protective seal and very dirty

This is a great book for the mid-range mathematician and relativistic incompetent. You can almost hear the humour shining through, and I just wish I had been able to actually hear him lecture.

E' la terza o quarta volta che compro questo libro per regalarlo a qualche studente bravo che prende la laurea triennale in Fisica, nella speranza di fargli venir voglia di diventare come Feynman.

Livro realmente muito bom! Feymann explica de maneira "simples" assuntos complexos, apesar das dificuldades e especificidades, dentro do livro alguns assuntos como derivadas e limites são abordados... Recomendo não começar a ler esses assuntos por ele, recomendo lê-lo após ter um conhecimento maior ma área.

For a genius to be a genius, is one thing. For a genius to be also a great teacher is the mark of a truly great genius! I am not a physicist. However, I have a love of the maths and sciences as they broaden our understanding of the natural world and reveal it to be a thing of great but hidden beauty. When Richard Feynman wrote this book, it is obvious to the reader that he loved to teach. The math is reasonably easy to follow. One of course should know how to manipulate algebraic equations and grasp geometric concepts. But what makes this an outstanding book is that this man knew how to take abstract concepts and make them understandable to the reader. Furthermore, he did this in a way that lightens the reader's intellectual journey with clever analogies, a touch of humour and a seemingly casual manner that captivates his audience. I strongly recommend this book to anyone who wishes to gain a real basis of understanding of this otherwise arcane subject. Read it. Learn. It's well worth the effort!

I read this book a long time ago when I was young. However, I discarded the book at 75 to prepare for the end of my physical life. Now I am 78 and forgot how Einstein showed his equation E = mc^2 in his theory of special relativity. Feynman explains the derivation of the equation very clearly. A good physics book!

Dives into vector, symmetry, special theory of relativity, curved space. Beginners will find it difficult to grasp. But others can understand fluidly. Book is in very nice condition... Btw do check my youtube channel of original music.... https://m.youtube.com/watch?feature=youtu.be&v=hOneHRXKdyc
