Well, then.I know most of you think this is a book in which Stephen Hawking explains the history of what we think we know about space and time and the beginnings and end of the universe.You're wrong.This is a book in which Stephen Hawking shows people like me how poor our comprehension skills are.WHAT EVEN IS QUANTUM MECHANICS!?And more importantly, who are these people who understand it!?Granted, I still use my fingers to count, so... You know what surprised me most about this book?As he was ta...

Stephen Hawking writes in a very simple and approachable way. On the surface the book has been written for the common man, for he who has little knowledge of theoretical physics. Hawking uses basic terminology and he tries not to overload his writing with explanations and information dumps, but at times it is very clear that the reader needs a certain level of knowledge to understand what he's talking about. As such, Hawking makes certain assumptions as he shifts from concept to concept which le...

This is an absolutely magical book, both objectively and for me specifically. I first read it when I was about 9 or 10, and ever since I've assumed that I didn't understand a thing, and read it as a childish boast. Fast forward nearly twenty years, degree and PhD in physics in hand, and I decided to give it a proper read. Much to my surprise I found that the book had permeated my brain! I remembered a huge number of the explanations, and the book resonated with the way I've thought about physics...

Isn't it amazing that a person can read a book like A Brief History of Time by Stephen Hawking and come away feeling both smarter and dumber than before he started? What a universe we live in!It's quite short and generally a quick read. Not every page is filled with mind-blowing/numbing theories and brain-busting equations. Some of it is just history, say on Newton and such. However, there were a few pages worth of passages where my wee brain felt like it was getting sucked into a black hole...m...

بمناسبة الثقب الأسود الذي توقعه آينشتين و تحدث عنه هاوكينج كثيرا في هذا الكتاب و وضع له النظريات و السيناريوهات و القفشات أيضا و بمناسبة الصورة التي نشرت في ابريل 2019 فهذه المراجعة ربما تذكركم بالكتاب الملهم المختصر الغني جدا بالمعلومات و الذي أعتبره بوابة أساسية لمن يهتم بما يحدث في الفضاء البعيدمع انى دارس هندسه فراغية و هندسة وصفية و مساحة جيوديسيه و رياضه بحته و تطبيقية و فيزياء عامه و ثيرمو دايناميك لكن حسيت و انا بقرأ الكتاب ده انى كنت أدبى و انى خريج دبلوم زخرفهده مش عيب فى الكتاب لكن عي...

Things I learnt from Stephen Hawking11 October 2014 Ever since I took up physics in year 11 I have had a love affair with the subject, which is odd since I went on to study an arts/law degree (but that probably had something to do with the fact that I would not have had the staying power to pour all of my energy into helping human knowledge advance towards establishing a unified theory). I still wonder where I ended up getting this book, and it had been sitting on my shelf for quite a while (pro...

"والواقع أننا قد أعدنا تحديد مهمة العلم لتصبح اكتشاف القوانين التي تمكننا من التنبؤ بالأحداث في الحدود التي يفرضها مبدأ عدم اليقين" بدأ ستيفن هوكينج, وهو عالم في الفيزياء النظرية, في كتابة هذا الكتاب في الفترة التي كان مازال يستطيع فيها أن يستخدم صوته وهو شبه مشلول على كرسيه المتحرك, ثم وبعد فترة, وقبل أن يكمل الكتاب, خضع لجراحة شقت فيها حنجرته, ليذهب صوته وهو الشيء الوحيد الذي كان يتواصل به مع العالم آنذاكظن في البداية أنه لن يستطيع إكمال الكتاب, ولكن أحد طلبته "بريان هويت" قام بمساعدته, ليس فق...

This book puts me in mind of the story about how a Harvard number theorist, through some malfunction of the scheduling computer, got assigned to teach an introductory course in pre-calculus. Being one of those individuals to whom math came so easily that they couldn't grasp how difficult others found it, the professor had no idea what to cover in such a course. 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...

It is not clear to me who is in the target audience for this book. At times it tries to explain basic concepts of modern physics in simple language, and at other times it assumes a familiarity with the same subject. For the first time I think I "understand" why absolute time is not consistent with relativity theory or that space-time curvature supplants the notion of gravity, and for that I thank the author. There are a few other things I believe I have a glimpse of having (finally) slogged thro...
