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 ،،

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 ...more

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

Things I learnt from Stephen Hawking
11 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

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 ...more

“The universe doesn't allow perfection.”
― Stephen Hawking, A Brief History of Time


I know. I know. I both loved and hated this book. I definitely should never have read this book, cut the pages, opened the box, etc.. Somehow Stephen Hawking has written a book that gently fluffs the tail on Schrödinger's cat (or perhaps Schrödinger's cat is fluffing Dr. Hawking).

Look, no doubt the guy is a genius and has a fantastic story (ALS, computer voice, nurses, Black Holes, strippers, movies, etc). My pro

Apparently this book tops the world list of "bought but not read", which may explain why it's so universally acclaimed as a work of genius. If you know anything much about relativity or cosmology, it comes across as a potboiler, admittedly a well-written one with a great final sentence. I wasn't impressed.

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.

Hawking is a brilliant physicist and a true expert in explaining highly complex aspects of our physical universe in terms that can be understood by most lay people.

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

Manny says this book is in the "bought but not read" category for most people. Well, I'm proud to say that I bought and read it, that too in nearly one sitting - back in my geeky days, when I used to get a sexual high just from solving a hard maths puzzle.

Unfortunately, I don't remember much of it (time for a re-read!) but I remember taking away the idea that time is a sphere. Being Indian, I loved this - because we are strong champions of cyclical time. Also, if time and space are both curved,

يسعى هوكينج في هذا الكتاب لوضع خريطة أو مسار كوني، بداية من الكيفية التي بدأ بها الكون، إلى وضع الاحتمالات التي سينتهي إليها، وتوضيح ما بينهما من أمور كونية فلكية.

بدأ الكتاب بالحديث عن الانفجار الكبير والمتفردة التي بدأ منها، وفيما بعد سيتناول احتمالات تنفي وجود متفردة أولية تقول بأزلية الكون، لكن المتفق عليه بشكل كبير في حالة وجود المتفردة أو لا أنه ثمة انفجار كبير بدأ منه الكون ثم تمدد، ومن الأشياء التي ستناقش بعد هذا هو الكيفية التي تمدد بها الكون. الانفجار الكبير كما قال هوكينج لا ينفي وجو

The main idea to take away from this book is that time has a clear direction. Entropy is the idea that the universe moves from highly ordered states to less ordered states. If you take the lid off a bottle of perfume, and leave it off for a few days the perfume will go from being highly ordered (all in the bottle) to highly disordered (all over the room).

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

A pesar de estar escrito para un público "no científico" no puedo decir que creo que sea un libro accesible al 100%. Es cierto que Hawking cumple su promesa de no incluir ni una fórmula matemática (excepto la conocida fórmula sobre la teoría de la relativdad E=MC²) pero los conceptos en sí pueden ser difíciles de imaginar y comprender. De toda la información que Hawking intenta explicar en este libro, ha habido cosas que notaba que se me escapaban. Quizá con algo más de material gráfico habría r ...more

On Horse-Flies: "A Brief History of Time" by Stephen Hawking

(Original Review, 1987)

Will having read Hawking's book help me understand the way a horse-fly "grasps" the arrow of time?
For starters, I'm great at killing horse-flies by hand. Should I get some black pyjamas and a balaclava and become a ninja? And there was me thinking that the horse-fly's all round vision and short nerve pathway had something to do with their reaction speed.

Without a doubt a masterpiece!
It's just incredible how Hawking explains to us the complex and mindboggling secrets and concepts of physics and our universe, with amazing wit , clarity, and simplicity.
The questions that we all used to ask to ourselves and to our parents, about god, about time, life and it's meaning, the sky, stars, about who created our universe and about it's beginning, about our fate......
we had that unique quality called curiosity when we were children, but then, as we grew up

Ένα πολύ ωραίο βιβλίο εκλαϊκευμένης επιστήμης που εξηγεί βασικές έννοιες της Φυσικής και πώς αυτές διαμορφώθηκαν ανα τους αιώνες - με κύρια κατεύθυνση στην μοντέρνα Φυσική που για πολλούς είναι ακατανόητη. Μου άρεσε πολύ ο τρόπος γραφής και το χιούμορ του Χώκινγκ αλλά θεωρώ πως κάποιος πρέπει να έχει κάποιες σχετικά γερές βάσεις Φυσικής για να το κατανοήσει. Θέλω πολύ να ξαναδιαβάσω τα κεφάλαια για την θεωρία των χορδών και τις μαύρες τρύπες γιατί νομίζω πως πολλά πράγματα τα έχασα. :(
Stephen Hawking's book is easy to read, but harder to comprehend. In every chapter came a point where my brain couldn't hold another permutation of a theory, and as the book progressed, I ended up taking the same approach as I do when reading a Norse saga for the first time. With sagas, I just read, even if my brain doesn't seem to retain all the information about who is related to who and what they named their horse. Inevitably, at the end, I have a reasonable basic grasp of the saga, and then ...more

A classic text where the amazing Stephen Hawking explains string theory and quantum mechanics "for dummies." Highly readable and even comical, it is a superb read. I need to go back and read this one again myself!

Oh, this is definitely one of my favorite books of science and my favorite one of Stephen Hawking. I love the way Hawking explains concepts so abstract and difficult to understand as time or black holes. It's a science book for the general public; you don't need to know math or physics to understand the amazing concepts about the Universe he tries to explain us. I totally recommend A Brief History Of Time to everyone, not only the lovers of science.

All I can really tell you with certainty is 'A Brief History of Time' is very logically organized, but as each chapter described a series of linked discoveries and what it all meant, unfortunately it mostly was still opaque to me.

Topics are introduced logically as Stephen Hawking describes in plain English the discoveries of scientists. He usually begins with observable phenomena which have led to verified maths (not actually detailed) demonstrating very likely how the Universe, and presumably

When he was eight, his family moved to St Albans, a town about 20 miles north of London. At eleven Stephen went to St Albans School, and then on to University College, Oxford, his father's old college. Ste ...more
