Stephen Hawking es un físico teórico cuya hipótesis sobre el tiempo, los agujeros negros y el espacio han constituido la forma en que actualmente pensamos en el universo. Su brillantez logra un dramatismo, debido a que su mente habita un cuerpo que se ha consumido por varios años a causa de una esclerosis lateral amiotrófica, la cual ha sido una enfermedad que lo ha dejado impedido para moverse o hablar, excepto un par de dedos que los utiliza con su computadora para relacionarse con el mundo.

There's nothing like the contemplation of the universe for making one feel simultaneously awe struck and incredibly insignificant.

Kind of random, but I loved Hawking's frequent use of the exclamation mark. For example::

"However, when an antiparticle and a particle meet, they annihilate each other. So if you meet your antiself, don't shake hands - you would both vanish in a great flash of light!"
"The supermassive black hole has a star orbiting it at about 2 percent the speed of light, faster t

An exceptionally good, concise look at physics for the layman. The explanations were just super. Simple, yet not stupidly so for me with my high school & Sunday supplement level of education on the subject. There are some tough concepts to understand. For instance, wave-particle duality is pretty weird, so be prepared to stop the book & think about what he says at times. Maybe even repeat his explanation. I found most became fairly clear, even time travel, but maybe not string theory. Th ...more

If you're thinking of reading A Brief History of Time, read this first. At least if you're a total civilian, which I am.

My son and I read this together. We did have to hit the Internet pretty hard a few times to get clarification on some critical points; but all in all, this is a well-written, accessible introduction to some pretty heady stuff.

I would recommend having the basics of atomic structure and the life cycles of stars under your belt before giving this a go. Also, it really helped my s

كتاب لطيف، مختصر، ومركّز، يجعلك تعرف بشكل جيد أكثر الموضوعات التي تهم علماء الفيزياء اليوم
يحوي الكتاب عدة موضوعات متّصلة بطريقة ما، قرأت عن أكثرها سابقا بشكل منفصل، لكني لم أجد كتابا مثل هذا جامعا لها، بشكل واضح يجعلني أفهم رغم أني لستُ مختصّا
استمتعت به، وأراه مناسبا لكل من لديه أسئلة حول الفيزياء والكون بشكل عام.

Kitapta zaman yolculuğu yapmanın neden mümkün olabileceği güzel anlatılmış. Solucan delikleri, zamanda yolculuk, galaksiler arası yolculuk gibi ilgi çekici konulara anlaşılır cevaplar verilmiş.

Wow and wow. I am not by nature a science person. The largely-repressed memories I have of high school chemistry still make me feel a little ill. But this, friends, is more like reading poetry than it is like reading a textbook. I am officially in awe of Stephen Hawking - the man can actually make you feel about subatomic particles and forces of nature. It's nothing short of amazing, really. I don't pretend to understand 99% of what the book discusses beyond an extremely superficial level, but I ...more

In an attempt to prove to some recent mega-brainiac friends (not that they asked me) that I was capable of some limited understanding of physics, I picked up this slim volume. The result: my brain hurts, I learned a few things, and I humbly submit that I will stay in the humanities. Although I think I got most of it, I nonetheless find it hard to accept certain things. I need some time-travel pills, as I am queasy. A lot of this material I learned in school or absorbed over time in media (and St ...more

To begin, I am not….scientifically inclined. But I would like to get a better grasp on some scientific principles, so I thought I would give this book a whirl. I didn’t grasp everything, by any means, but the book is very informative. I found it very interesting to learn how little/much physicists know about the universe, its properties, and the struggle to find natural governing laws that consistently prove true. I feel that I’ve learned a great deal from this book, and will probably read it ag ...more

"A briefer history of time" is briefer and simpler version of "A brief history of time". However I wish explanations to some theories made sense to me. I still feel unfullfilled about string theory and multi dimensions.

In addition, the language was a bit dry, or so I thought. After Carl Sagan's flowing poetry-like language, I am unimpreed by Stephen Hawking. Still humor wasn't absent.
Apart from those, I liked this book. Got good deal of information and understanding of theories. After reading sc

Коротка і просто написана книга про фізичний світ (чи світ фізиків, якщо бути точним). Початок оманливо простий, але автори швидко піднімають рівень - переходячи до складніших питань.

Одним з важливих сюжетів книги є питання: "Чи Бог існує?" Адже фізики відомі своєю схильністю до атеїзму. Але автори не займають чіткої позиції, хоча у висновку все ж розкривають карти: питання "Навіщо?" - це питання філософії, а не фізики. І скрушно додають, що філософи тепер не ті - вважають, що вивчати можна лиш

الكتاب بيتكلم عن كيفية نشئة الكون من وجهة نظر علمية ، المفروض إن الكتاب ده هو تبسيط للكتاب الأصلي " موجز تاريخ الزمن " بس للأسف الكتاب لسه بيحتوي على معلومات و نظريات صعبة و معقدة على غير المتخصصين زي حالاتي .

الكتاب ممكن تطلع منه بشوية معلومات مفيدة كل كام صفحة و لكني في النهاية لا أنصح بيه لغير المتخصصين أو الباحثين في علوم الفيزياء و الفلك.

Imagine you are a tiny particle, one that lived throughout the universe since the beginning of time. You witnessed the dawn of creation, and within you lie the rules with which the end can be foreseen. You are fully aware of the characteristics of space-time. Relativity & Quantum Mechanics are nothing but infant struggles to identify you and your behavior. You could even be a string! But nobody can say for sure, for only you have that knowledge.

I love Physics. And I suck at understanding Physics. But I try. I can actually identify the paragraph where I get lost. I guess that, at least at this time in my life, I'm not capable of getting my head around the concept of a unified and relative space-time and all the implications it carries (such as the bending of time near large gravitational fields, differences in aging the farther one gets from the center of a large gravitational field, and that whole section about time travel).

Very readable, and I was actually surprised to realize I'd learned most of this information in an astronomy class I took in college. Who knew I was this educated?

The end of the book, where Hawking discusses the theories that scientists are currently trying to prove, started getting to be a bit above my head - in my lay opinion, I think it was a combination of Hawking getting a bit more vague and having fewer concrete facts and observations to state.

En mi opinión, está bastante bien para ir alimentando el gusanillo de la curiosidad y desengrasando el cerebro que solemos tener de vacaciones (al menos en estos temas) y preguntarnos cosas como: ¿cuál es la naturaleza del universo? ¿Cuál es nuestro lugar en él, y de dónde surgimos él y nosotros? ¿Por qué es como es?
¡De vez en cuando no está mal leer algo distinto!

I began watching Neil Degrasse Tyson's Cosmos last year and it rekindled my interest in learning about physics and astronomy. It began when I watched Carl Sagan's Cosmos, which I loved. I would dream about the stars at night. So Stephen Hawking's A Brief History of Time caught my eye. Now, I had always been total shit at physics class in school and I excelled in the IGCSE/A Level programs of English Literature, Biology and Modern History.

This is ridiculous, I finished it in less than a day! Yes, it's that interesting and overwhelming, no matter if you've read the earlier version of this book - A Brief History of Time, or how many times you've watched Stephen Hawking's popular series on BBC.

This is Stephen Hawking’s way of describing gravitational attraction of composite bodies.

And you recognize good old Stephen Hawking humour when he introduces Isaac Newton by stating that "Isaac Newton was not a pleasant man."

كتاب ممتاز لغير المختصين يأخذ القاريء في رحلة عبر تاريخ نظرة الإنسان للكون: من تسطح الأرض و مركزيتها, إلى كوبيرنيكوس و مركزية الشمس, وصولا إلى نيوتن و مداراته الإهلجية, ثم إلى نسبية أينشتاين و نزع مفهوم الإطلاقية عن الزمن و اعتباره بعدا رابعا, و أخيرا و ليس آخرا نظرية الأوتار الفائقة بوصفها محاولة لتوحيد القوى الفيزيائية و ما يشوبها من نقص

ما أعجبني: سلاسة الطرح التي غلبت على الكتاب إضافة للأمثلة المرسخة و المبسطة للمفاهيم المطروحة

This will be a shorter-than-usual review for me, but it doesn't seem necessary to add much more to the many excellent reviews of this book. This is the Hawking-Mlodinow easy-reader (because his best-seller A Brief History of Time was bought to make people seem better informed, but not actually really read. The challenge here was to comprehensively and cogently present complex concepts like relativity, quantum theory, string theory, etc. without using *any* numbers whatsoever (not even powers of ...more

رحلة فيزيائية جميلة من عظيم هذا الكون الى أبسط جزيئاته. شعرت بالأسف حيث أن دراستي الثانوية كانت بالفرع العلمي ومن ثم تخرجت بكالوريوس من كلية علوم ومن ثم تخرجت ماجستيرا من كلية علوم ومع ذلك، فإن معظم المعلومات كانتمعلومات جديدة بالنسبة لي. هي في أساسيات القوانين الكونية وقوانين الفيزياء

La estructura del libro es la de una cronología. Va desde los primeros descubrimientos sobre nuestro universo hasta las teorías más complejas, es por ello que, inicia remontándose a las ideas de Aristóteles y Ptolomeo que instauraron el modelo inicial de nuestro sistema solar con la tierra en el centro, y que luego fue refutado por Copérnico que pensó en el sol como el cuerpo central. Esta teoría heliocéntrica no fue tomada en consideración hasta que Galileo y Kepler la apoyaron y confirmaron un ...more

Une belle histoire du temps offre un aperçu de l'histoire de la physique allant des anciens Grecs et, surtout, de Copernic à l'actuelle quête d'une théorie quantique de la gravité, en passant par la relativité restreinte et générale, les théories des cordes, le principe d'indétermination, l'intégrale des chemins et la dualité onde/corpuscules. L'ouvrage se veut concis et clair, et abonde en expériences de pensée illustrant les arguments et problèmes centraux de chaque système.

An even shorter version of a History of time... then a brief history of time and now a briefer history of time. I dont care how short he makes the next one. If it will take physics and make it digestible to the average joe then I'm all for it.

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

At eleven Stephen went to St Albans School, and then on to University College, Oxford, his father's old college. Ste ...more
