Stephen Hawking A brief history of time

I also describe the progress that has been made recently in finding “dualities” or correspondences between apparently different theories of physics. These correspondences are a strong indication that there is a complete unified theory of physics, but they also suggest that it may not be possible to express this theory in a single fundamental formulation. Instead, we may have to use different reflections of the underlying theory in different situations. It might be like our being unable to represent the surface of the earth on a single map and having to use different maps in different regions | Updated Most Popular Stuff On The Net.

That was done by Carl Sagan. Instead I wrote a short piece titled Acknowledgments in which I was advised to thank everyone. Some of the foundations that had given me support weren t too pleased to have been mentioned however because it led to a great increase in applications.

It has been translated into something like forty languages and has sold about one copy for every 750 men women and children in the world. As Nathan Myhrvold of Microsoft a former post-doc of mine remarked I have sold more books on physics than Madonna has on sex. The success of A Brief History indicates that there is widespread interest in the big questions like Where did we come from And why is the universe the way it is I have taken the opportunity to update the book and include new theoretical and observational results obtained since the book was first published on April Fools Day 1988 . I have included a new chapter on wormholes and time travel. Einstein s General Theory of Relativity seems to .
