Look at my new online photo album filled with pictures from my vacations, sporting events, and several places around the world.

I have just finished reading an excellent book, "The Da Vinci Code" by Dan Brown, who masterfully concocts an intelligent and lucid thriller. It has enough twists and turns in a short amount of time and contains hidden codes, murders, secrets, conspiracies, art history lesson, chase story and religious symbology lecture. A really brainy stuff. Now, I start reading another excellent book by Stephen Hawkins which is entitled "A Brief History of Time". It throws new light on the modern physics and it is so well-written that an amateur in physics could understand difficult terms such as Black Holes, Supernovas or Einstein's theories. First of all, the author tries to explain the Universe, how was created, how is it expanding, why is the universe the way it is and and how will it end. He also writes about Space-Time, the Arrow of Time and the unification of physics. His intension, in general, is to find a  unified theory, complete set of all laws of physics (the idea of Albert Einstein) and he believes that a complete, consistent, unified theory is only the first step, "...our goal is a complete understanding of the events around us, and of our own existence...". Einstein once asked the question: "How much choice did God have in constructing the universe?"
Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe?... Why does the universe go to all the bother of existing? Is the unified theory so compelling that it brings about its own existence? Or does it need a creator, and, if so, does he have any other effect on the universe? And who created him? ... if we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just a few scientists. Then we shall all, philosophers, scientists, and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason - for then we would know the mind of God.

In sum, I believe that both books are well worth reading, practical, informative and challenging and I suggest both of them.
