A Brief History of Time
In the ten years since its publication in 1988, Stephen Hawking's book has become a landmark volume in scientific writing, with more than nine million copies sold worldwide. That edition was on the cutting ed...more

هناك لذّةٌ ما ،، في أن تفتحَ كتاباً تشعُّ من سطوره ألوان الفضاء
شيءٌ ما في فعلِ المعرفةِ ،، والتأمل فيها
شيءٌ يأخذ عقلك إلى أمكنةٍ أخرى
لا بين المجرات
ولا في خضّم الكونِ الواسع
بل هنا بداخلك
عند هذا النبض الأخّاذ في قلبك
حيث تبدأ المتعة في التحرر
لتغمر مسامّك برائحة الدهشة
فالكون في داخلك أنت يا صاحبي
تاريخٌ موجز للزمن ،، يُعتبر من أهم الكتب العلمية الحديثة
يأخذك ستيفن هوكنج في رحلةٍ عبر تاريخ العلم
ويشرح لك كيف تغيّرت نظرتنا للكون ،، ولمجرتنا ،، ولكرتنا الأرضية ،، ولأنفسنا كذلك عبر العصور
So, he went to the chair of the department, who told him: "You'll want to start with the real number-line and then progress to inequalit...more
Where Hawking fails, in my opinion, is his hubris. He proceeds in to the realm of metaphysics and religion in several portions of this book. For instance, in his chapter on the "arrow of time", he states that, essentially, the universe can only move in one direction of time. It cannot go backwards. He also states that this limits the...more
Hawking uses this idea to explain why travelling back in time is impossible. It requires very little energy to knock a glass over and smash it...more
But... without it, we would never have had MC Hawking. If you haven't come across him, start with the lyrics to "E = MC Hawking". Then buy A Brief History of Rhyme.
At times Hawking lost me. He wants to explain theory to the masses, but as he draws near to his own theory, he got...more

The book starts out by discussing theories as they developed, beginning with theories we all are familiar with and consider trivial, and then showing how they have proven to be wrong in des...more
Overall, this book was pretty good, but I guess the biggest problem I had with it was that Hawking never really came out and declared which of the current theories he most subscribes to. He does a great job presenting a mostly unbiased view on the differing theories, but doesn't take a stance on which he thinks is the b...more
It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination.
That was somehow lost in our information generation. So like I said, if this tiny take on life and physics gets into more hands then horray. Its a crazy world out there. Be curious.
This book takes topics like general relativity, quantum theory, string theory, the universe, it;...more
Essentially, as you may know, Christian Marclay assembled a 24 hour film out of clips from zillions of movies. Each clip features the TIME on a clock or watch or in the dialogue, and of course it's all in order, and the film runs continuously, so if you start watching it at 4.17 there you will see a clip where it's 4.17 in some Jimmy cagney movie from 1936... etc etc......more

A landmark volume in science writing by one of the great minds of our time, Stephen Hawking’s book explores such profound questions as: How did the universe begin—and what made its start possible? Does time always flow forward? Is the universe unending—or are there boundaries? Are there other dimensions in space? What will happen when it all ends?
Told in language we all can understand, A Brief History of Time plunges into the exotic realms of black holes and quarks,
It is difficult, from the contents of A Brief History of Time, to see how it managed, famously, to become the least read bestseller of the twentieth century. The answer, of course, is the romance of Hawking's life and the way in which he was able to overcome his disability.
The book itself, in this revised edition marking the tenth anniversary of the original publication, is a clear account of modern cosmology from one of the subject's leading r...more
In retrospect, I really enjoyed it. It mostly served as a good refresher for a lot of freshman physics I have seen a couple of years ago, particularly the first half of the book where Hawking explains the ground work on which he built his own theories. The historical part of the book was great not only because of the content, but because we can also see...more
Hawkings explained connections between time, space, and physics. He shows how people use what they know about space and physics to lear about time, and vice versa. He talks about how...more
On the other hand I have *loved* A Short History of Nearly Everything and Fermat's Enigma: The Epic Quest to Solve the World's Greatest Mathematical Problem, finding them as gripping as a thriller.
