كتاب يفترض انه مبسط للعامة للعملاق العبقري ستيفن هوكينغ

يتحدث عن اخر ما توصلت له علوم الفيزياء والفيزياء الفلكية، يسرد علينا كيف بدأنا فهم الكون من ارسطو الى كوبرنيكوس الى جاليليو الى نيوتن واينشتاين الى العلماء الذين اوجدوا نظرية الكم

وهنا بقي ستيفن محتارا كيف ان النسبية ونظرية الكم متضادتين، وبقي يحلم ويعيشنا في حلم ان نصل الى نظرية موحدة

كل هذا وكثير من المعلومات التي وردت في الكتاب اعرفها قبل ان اقرأ هذا الكتاب، ولم اجد شيئا جديدا افهمه وانا امام هذا الكتاب المشهور ليس لأنني ختمت العلوم الفيزيائية، بل لأن عقلي للأمانة لم يستوعب اغلب المعلومات الجديدة علي، او حتى بعض القديم منها، نظرية الكم والزمكان ونظرية الأوتار، عندما اقرأ كلمة كهرومغناطيسية أتذكر اني درست مقرر اسمه الكهرومغناطيسية في الثانوي، وسبحان الله لا أتذكر منه شيء كأني لم ادرسه مع اني حصلت على درجة عالية فيما يبدو


تحية الى العباقرة محبي العلوم الذين يفهمون مثل هاته المعلومات الصعبة،

Nothing like physics and astrophysics to humble yours truly! Man, I’m sure if I understood everything I just read, I would have given it a 5, but my favourite part was probably learning that Isaac Newton was an a*shole as a person, so here we are.

All jokes aside - our universe is fascinating and so is the book. It just takes a lot of brain power to understand some of the concepts for the Humanities grad like me.

A must-have volume for readers of popular science!

The title says it all and is probably the best summary of this exciting and entirely accessible popular physics book. A BRIEFER HISTORY OF TIME is both an update on and a more succinct, briefer version of Hawking's best-selling original work, A BRIEF HISTORY OF TIME. In a whirlwind review of man's scientific exploration of the working of the universe, Hawking and his co-author Mlodinow summarize our knowledge of the evolution of the universe from its earliest beginnings to today and bring a curious reader up to date on the state of the theories that, for now at least, best describe such complex, mystifying cosmological material as dark matter, black holes, worm holes, the difficulties of combining quantum mechanics and general relativity into a single mathematical formulation, string theory and even the possibility, however remote, of time travel.

It's simply a given that someone who is interested in physics would find such material interesting and exciting. So it remains only to say that the achievement in writing such a fine book is to make the material accessible to mere mortal readers whose intellect simply can't compete with the likes of Stephen Hawking. With a wonderful combination of text and enlightening accompanying illustrations, A BRIEFER HISTORY OF TIME easily clears that standard and deserves a place in any interested reader's popular science library.

Highly recommended.
