Tuy nói tác giả viết quyển này cho đối tượng phổ thông, nhưng mình thấy nó không dễ hiểu đến vậy.

Nội dung chính là giới thiệu và giải thích một số đề tài được yêu thích trong vật lí lí thuyết như không - thời gian, lỗ đen,.. bằng toán học và lập luận. Từng chủ đề đi tương đối sâu và có nhiều thuật ngữ được sử dụng nên người mới tiếp xúc (như mình) cần đọc chậm. Bù lại nắm được thì thấy khá hay.

Bên cạnh đó còn có các đề tài thú vị như du hành thời gian, vòng lặp,... được mổ xẻ chi tiết theo hướng kĩ thuật. Chứ không chỉ đưa ra các nghịch lí gây tò mò như nơi khác.

Tổng quát mình thấy đây là sách khoa học hay. Độ khó hiểu tầm trung bình. Nên nếu là dân ngoại đạo mà muốn tìm hiểu (như mình) thì cũng có thể xem qua.

Jätsin raamatu kusagil 1/3 peal pooleli, kuna selle lugemise vaib läks täiega üle + teised raamatud tundusid palju intrigeerivamad.

Iseenesest annab väga hea ülevaate Universumi lihtusest ja sügavast keerukusest. Kuna ma pole hingelt füüsik, kippus lugemine natuke automaatseks tähtede ülelugemiseks minema.

Ei anna raamatule hinnangut, kuna teos on ilmavalgust näinud siiski 2000ndate varases alguses ja selle ajaga on mingid põhitõed kindlasti ümber lükatud ja täiendatud ja/või on avastatud sootuks midagi uut. Sestap jäi tegelikult ka lugemine poolikuks, et ma polnud kindel kirjutatu 100% paikapidavuses (mis pole halb omadus, lihtsalt aeg ja uued teadmised tuhmistavad vanu).

O livro “The universe in a nut shell” é um livro sobre física teórica escrito pelo físico Stephen Hawking. Voltado explicitamente ao público leigo, apresenta, de forma clara e sem o uso de matemática, as principais ideias antes e hoje debatidas pelos físicos teóricos, abrangendo desde o mundo quântico até o gigante universo; abordando desde a possibilidade de existência de partículas fundamentais ainda não detectadas, de buracos negros e de viagens no tempo, até o destino biológico e tecnológico da humanidade em um futuro não muito distante.

While I am massively under-qualified to understand most of this book, having taken chemistry and physics classes, watched some lectures and read a few additional books, I understood the concepts that Hawking was exploring, if not the math or the reasoning behind most of them, and I think that's good enough for now.

Since this is currently a 20-year-old book, I imagine a few of the concepts may be slightly outdated. Quantum physics is not the kind of field that changes very much in a short time period unless there's a huge observational breakthrough, but I'm sure I'll have a better understanding of Helgoland: The World of Quantum Theory having read this book first.

I recommend reading a physical copy of this book because the graphics help immensely.

Dá pra ganhar conhecimento geral de muita coisa nesse livro, pegar de tempos em tempos pra ler é uma boa atividade, mas muitas vezes tive de recorrer à internet pra compreender melhor o que o autor queria dizer. Sinto que o Hawking fortalecia o esteriótipo de gênio e de que ciência dura é difícil, e como divulgação científica acho isso muito chato, porque discordo, mas de qualquer forma é uma leitura proveitosa. Dos livros dele espero que não seja o melhor. Recomendo 6/10.

Wie auch sein Vorgänger - ein Buch, das jeder im Schrank haben sollte.

Empieza explicando y enlazando bien distintos conceptos de física teorica bastante avanzados, pero hacia el final se le va un poco de las manos y acaba siendo enrevesado, en mi opinión, para alguien que no tenga una cultura cientifica bastante trabajada.

Un libro muy difícil pero delicioso. Hawking muy Hawking, fiel a su estilo, con una narrativa no demasiado didáctica, con sus toques excéntricos que me disgustan pero hablando de temas de los que solo él y muy pocos más, contados con los dedos de la mano, pueden hablar. Que una mente así se abra para acercar temas tan controvertidos, interesantes y avanzados como los que trata es para agradecerlo. Este es de esos libros que cambian vidas. Así que Hawking, muchas gracias. De verdad.

I’m not going to pretend that I understood most of it but he does raise a few thought-provoking points about the future of the human race. Plus it’s very well written.

I really liked "A Brief History of Time" much more.

While it isn't that bad (it's actually very good), in comparison with Brief History, it seems only to have many more illustrations and fewer thorough explanations.

I understand that Hawking tried to write a popular science book with a branching non-linear structure without depending heavily on what has been said in the previous chapters, but I don't think that's actually possible. At least I honestly doubt it could be done without losing a significant portion of quality and precision.

I don't know, I read too much about these kinds of things anyway so I guess I might not be right, it could be just what an intelligent layman without too much time needs. But that's a big maybe. Try it, after all, I put 4 stars up there for a reason.

This is not a book you can read on the bus to work, or if you just want to relax. This is not something easy to read. You can notice that Stephen tried his best to explain concepts that are by far not easy to explain. I had to read some of the pages multiple times, until I was almost sure that I understood at least some of the things that were explained. I know that this subject is not for everyone, but even if you grasp half of what this book contains, I believe you will have a much better understanding of the theories that try to explain everything around us.
The universe around us is fascinating!

I do not yet have intellect enough to comprehend the entirety of the book. However, for the extent I managed to understand, I must say it was incredibly brilliant. I didn't begin the book with the expectation of thorough understanding, so there was no disappointment. Furthermore, it was actually a relief that I could get a lot of the stuff in the book considering the fact that it is written by Hawking. I am glad I gave it a try. I will boldly explore science non-fiction from now on.

As for the writing, his simple language coupled with complicated theories resulted in a good flow. There is occasional intelligent humour that makes you chuckle in delight and subtle satire that helps you connect with Hawking.
