If you move at high speed, time slows down, space squashes up, and you get heavier. Travel fast enough, and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing - and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes....
These are but a few of the extraordinary consequences of Einstein's theory of relativity. It is now over a hundred years since he made these discoveries, and yet the general public is still largely unaware of them. Filled with illuminating anecdotes and fascinating accounts of experiments, this book aims to introduce the interested lay person to the subject of relativity in a way which is accessible and engaging and at the same time scientifically rigorous. With relatively few mathematical equations - nothing more complicated than the Pythagoras theorem - this VSI packs a lot of time into very little space, and for anyone who has felt intimidated by Einstein's groundbreaking theory, it offers the perfect place to start.

The first explanation of the distinction between the Special and the General parts of Relativity that started to make sense. Now I have to go back and re-read it so I can remember how to explain what Inertial Frame of Reference is.
The whole manifold concept of spacetime is fascinating, along with the effect of velocity and gravitational field on the observed rate of time. Can all points in time exist in each point in space?
Got to go and study "Frame-dragging" more so I can get the significance of that too.
Lots more to read it for - could be looked as a simple intro to the development of the math involved in Relativity for non-mathematicians.
Just read it - or better yet, listen to the audio, then read it.
