This book contains the great physicist's own explanation of both the special and general theories of relativity. Written for readers interested in the theory but not conversant with the mathematical apparatus of theoretical physics, it presents the ideas in their simplest, most intelligible form.
Some years ago in France a book by Jean-François Gautier appeared, entitled Does the universe exist?.
What if the universe were a concept like cosmic ether, or phlogiston, or the conspiracy of the Elders of Zion?
Philosophically, Gautier’s arguments make sense.
The idea of the universe, as the totality of the cosmos, is one that comes from the most ancient cosmographies, cosmologies, and cosmogonies. But can one describe, as if seeing it from above, something within which we are cont...more
The biggest problem I had with this was actually one of presentation. The team which had prepared it for release had presented all the equations as jpegs, a reasonable idea when reading it in HTML, but not a good one when reading it on a Kindle! Still, who am I kidding - the equations probably wouldn't have made sense to me anyway....
I am an arts graduate trying to understand relativity. I've read Hawking, and I've read Cox, and I thought I should r...more
In the Special Theory of Relativity, Einstein states that space and time are not fixed properties, that they are intimately connected to each other (hence, spacetime, "ST"), that time and space are shorter and slower as an object moves closer to the speed of light, and that mass increases with the addit...more
It surely imparts some best lessons for life, that keep your subconscious alert and curiosity should be the prime element of every thought process. The thing that Einstein got the idea of relativity while going home in a car, he saw the time in clock mounted on top of church, and it gave him the storm t...more

During middle school, or possibly during the freshman year in high school, I started going to the library to rea...more
I'm not going to go into the general and special theories of relativity, because I honestly only understand the theorie...more
What is most remarkably about this book is that it provides an excellent framework for the special and general theories without necessitating the understanding of advanced math. As someone who loves math, this is not something I would normally laud, but, in...more
Other summaries of relativity I've read by Hawking and Greene have been good but not as comprehensive. More dumbed-down versions are usually nothing more than analogies that offer no real insight.
As far as the math credentials, Einstein introduc...more
It is essentially a must to be very comfortable with college-level algebra and an understanding of basic Newtonian mechanics is certainly helpful. A persistent reader could probably find utility in this book if they were not particularly well-versed in basic math, though.
Also, I skipped the first 2 appendices. There was little hope for me,...more
the twin experiement. two twins with two 'clocks' (mirrors attached to the end of a mitre stick with a photon rebounding within the two mirrors), one twin boards a spaceship, one stays on earth. How do the twins age relative to eachother?
Turns out, relative to earth, the twin aboard the spaceshuttle ages less quick than the twin on earth....more
Even if you are not into science this is an important work of pure clarity that should be recommended reading everywhere......
I love this book so take a chance you may gain more from it than you expected........
