Six Not-So-Easy Pieces: Einstein’s Relativity, Symmetry, and Space-Time by Richard Feynman

No twentieth-century American scientist is better known to a wider spectrum of people than Richard P. Position and time measured in one frame of reference one observer is different from another frame of reference another observer. In addition to his work in theoretical physics, Feynman has been credited with pioneering the field of quantum computing, and introducing the concept of nanotechnology creation of devices at the molecular scale.

In a few short lessons, he showed me what had taken months at university to understand. But how can a series of equations predict the mass? We have grown up in a 3-dimensional world that we understand somewhat, and it’s not easy to grasp relativity, curved space, of space-time, let alone curved space-time. The only thing we might suggest is something like this: He is a populist in the best sense of the word, in that he thinks, not that we ought to dumb down our subject to reach as many people as possible, but that people will be interested and understanding if only we stopped putting on airs and spoke clearly.

Open Preview See a Problem? Feynman designed these lectures so that, he hoped, physics non-majors would be able to grasp the concepts, while majors would get a sense of the excitement of physics and maintain their interest.

The example of page 64 establishes that simultaneity is not a unique thing in the universe, because it means different things to different observers. Hopefully though continued exposure I absorb just a little at a time. Oops, now we are supposed to know what a Lagrangian is to understand the significance of what he has done, generating classical mechanics purely from optimizing proper time in relativity.


This is a very entertaining book by an amazing teacher. He gives you the general principle, and then walks you through an example. The difference between spacetime, and space and the interval provides interesting sense of reality. But to do that we need to move the projectile up quickly, which slows down its time.

The book also had Feynman’s characteristic humor and crazy imagination to illustrate really tough physics and mathematics. Jul 24, Vikas Datta added it.

But, as Feynman shows so clearly and so entertainingly in the lectures chosen for this volume, these crazy notions are no mere dry principles of physics, but are things of beauty seos elegance. Jan 21, Abdulrahman Kauther rated it it was amazing. Writing this review many months after reading the book I find I can’t remember how well it worked for me.

Insight for non-mathematicians I’ve often wanted to understand how mathematics has been used to define laws that are proven, descarrgar not, by experiment. Apr 09, Prooost Davis rated it really liked it Recommends it for: Requires, and assumes, knowledge of Std XII Maths and Physics- you’ll be pretty lost if you don’t know what the hell differentials and integrals are.

The description of the object also depends upon the frame of reference observer. Feynman is as enigmatic as usual and his descriptions are vivid and inspiring. You can likely make it through it and learn things even if you have difficulties with the math. It is a foundational ingredient of the very universe in which we live.

When we look at an object, we find that it has an apparent width and depth, but they are not fundamental properties of the object, because if we look at it from a different frame of reference it would look different.


I found it interesting that the curvature of a sphere is the same as for a disk with a temperature that gradually increases out from the centre, which causes anything on it to expand accordingly.

He starts slowly, even simplistically with a discussion of piezaas and builds one upon the other taking the reader through some relativistic topics and finally concluding with a fantastic description of space-time geometry. However, the last chapter made the pieaas spent well worthwhile for me. Dec 22, Ashudza Uchiha rated it it was amazing. I generally suggest avoiding this book and its outdated approach to Special Relativity.

For his contributions to the development of quantum electrodynamics, Feynman was a joint recipient of the Nobel Prize in Physics intogether with Julian Schwinger and Sin-Itiro Tomonaga. He has a keen sense for the dramatic, and will unveil a physical principle like a magician pulling a dove from a hat.

But this is a book reviewing site, after all, descaggar review them I must. Persistent references to other parts of the original work sometimes leave information wanting, but generally the concepts covered are well explained in a creative plezas direct manner intended to shed light on difficult ideas without being convoluted or contradictory.

In summary, this is a jewel of a little book that I thoroughly enjoyed and which deserves a full 5-star rating.

The book really made me appreciate the power of mathematics and interpretation to determine the nature feynmaan the real world. Why is nature so nearly symmetrical?

Feynman is a wonderful teacher, who can get right to the core of topic with amazing facjles, and he has the gift to make even the potentially most complex concepts seem like the most obvious and commonsensical thing.
