"In his phenomenal bestseller A Brief History of Time, Stephen Hawking literally transformed the way we think about physics, the universe, reality itself. Widely regarded as the most brilliant theoretical physicist since Einstein, he has opened our minds to today's most important scientific ideas about the cosmos. Now Stephen Hawking returns to shed new light on the darkest regions of space and time...and to reveal an extraordinary array of possibilities for our understanding of the universe." "These thirteen essays and one remarkable extended interview broadcast over the BBC on Christmas day 1992 range from the autobiographical to the purely scientific. Building on his earlier work, Stephen Hawking discusses imaginary time, how black holes can give birth to baby universes, and scientists' efforts to find a complete unified theory that would predict everything in the universe, a concept that he believes will come to seem as natural to the next generation as the idea that the world is round." "With the great unfolding mysteries of the universe as a backdrop, Stephen Hawking also reflects on free will, the value of life, and his perceptions of death. He looks at how science theory converges with - and diverges from - science fiction, as well as how science fact interfaces with our own lives." "The pieces in this collection reveal Stephen Hawking variously as the scientist, the concerned world citizen, the man, and - always - the rigorous and imaginative thinker. Severely disabled by ALS - Lou Gehrig's disease - he describes the way in which this has affected but not constrained his personal and intellectual life: from the special computer technology that lets him translate his thoughts into words and his words into sounds, enabling him to write and speak, to the process of evolving his ideas, teaching his students, and working with his colleagues.".… (lisätietoja)

As other viewers have noted, this is not a book in the same mode of [b:A Brief History of Time|3869|A Brief History of Time|Stephen Hawking|https://d2arxad8u2l0g7.cloudfront.net/books/1333578746s/3869.jpg|2192250]; it is a compendium of assorted essays and interviews and talks from 1976-1992. If you're curious to discover more of Stephen Hawking the man and evolving physicist (essays 1-6, and the interview at the end), this is your book. If you're look for more popular science, this is probably not it--though the science essays (7-13) are still devoid of the complex formulae found in whitepapers.

Hawking emerges from these pages a brilliant man who has persevered and maintained a solid character of balance and optimism in the face of detrimental physical limitation. He states that, after diagnosis, he "felt somewhat of a tragic character" and "took to listening to Wagner," but he also clears up the media-marketed rumors that he drank heavily (23). He presents his position that the physicist view of "reality" is really just a mathematical model used to describe observations--further, "[i]t is no good appealing to reality because we don't have a model independent (sic) concept of reality" (44).

In one essay, he cleverly refutes the anthropic principle (53); in another he makes clear that physicists, i.e. "the people who actually make the advances," do not think in terms of the categories that historians and philosophers subsequently assign to them (42); and in yet another he says that his desert island music would be Mozart's Requiem and his desert island book would be George Eliot's [b:Middlemarch|19089|Middlemarch|George Eliot|https://d2arxad8u2l0g7.cloudfront.net/books/1386924110s/19089.jpg|1461747] (keeping in mind that Shakespeare and the Bible are implied).

My head turned at this book selection. Stephen Hawking reading Middlemarch? Alas, he is a dynamic human being after all. ( )

"No estoy de acuerdo con la idea de que el universo constituye un misterio que cabe intuir pero que jamás llegaremos a analizar o a comprender planamente", afirma Hawking en el prólogo. Y al hacerlo, le hace justicia a la revolución científica iniciada hace casi cuatro siglos por Galileo y desarrollada por Newton. Ellos demostraron que algunas áreas del universo no se cojmportan de manera arbitraria, sino que se hayan gobernadas por leyes matemáticas precisas. Todavía es mucho lo que no sabemos o entendemos acerca del universo; pero el gran progreso logrado, sobre todo en los últimos cien años, debe estimularnos a creer que el entendimiento pleno no se encuentra fuera de nuestro alcance. Esta es la firme creencia del autor de estas páginas, convencido de que pugnar con conseguir una teoría definitiva acerca del universo es mucho mejor que desesperar de la capacidad de la mente humana. Tal vez no estemos, después de todo, condenados a avanzar a tientas en la oscuridad. Este libro da fe de esta luminosa posibilidad.

Unfortunately, it was no better than a recap by way of various essays of his more well-known work. Very readable, but no new info. I should have just done a little rereading. ( )

Tras el exitazo cósmico de "Una breve historia del tiempo", el maestro Hawking empezó a darle a la manivela y produjo unos cuantos libros que, seguro, no estaban previstos inicialmente. Éste es uno de ellos, una colección de breves artículos que empiezan con lo biográfico (mi bisabuelo era de Sussex y se arruinó por comprar demasiadas granjas) y terminan con lo filosófico (hablemos de cómo la mecánica cuántica es compatible con el libre albedrío) pasando por el camino por bastante física. Un libro corto, disfrutable y muy bien escrito que se lee mucho más fácilmente que el primero del autor. ( )

სტივენ ჰოკინგის ესეების და ლექციების (და ინტერვიუ) ნაკრები, სადაც ის მისთვის ჩვეული ადვილად გასაგები ენით მოგიყვებათ კოსმოლოგიის იმ მთავარ საკითხებზე რომლებზეც კარიერის განმავლობაში მუშაობდა და ფიქრობდა.
მეცნიერული თემების გარდა, შეხვდებით ავტობიოგრაფიულ ესეებს, სტივენის ოჯახურ ცხოვრებას, ადრეულ სიყმაწვილის პერიოდს, დაავადების განვითარების და ოჯახის შექმნას. ოქსფორდის და კემბრიჯის პერიოდს, გაიგებთ როგორ დაიწერა სტივენის ბესტსელერი "დროის მოკლე ისტორია" და ა.შ.
ლექციების უმეტესობა 80-იანების მეორე ნახევრით და 90-იანების დასაწყისით თარიღდება, ასე რომ რამდენიმე ლექციის შემთხვევაში სამყაროს მომავლის წინასწარმეტყველებას რამდენიმე მნიშვნელოვანი პრობლემა და მთელი რიგი ინტერპრეტაციები და სცენარები აკლია. რაც სრულიად გასაგებია სამყაროს აჩქარებით გაფართოება და ბნელი ენერგია უფრო ახალი აღმოჩენებია, ეს ყოველივე გათვითცნობიერებულ მკითხველს აგრძნობიენებს რა სწრაფად იცვლება სურათი და რა მასშტაბებს აღწევს პროგრესი.
გარდა ზემოთ ნახსენები ფაქტისა ჰოკინგის ადვილად გასაგები ახსნის უნარი, მისწრებაა კოსმოლოგიაში გაუთვითცნობიერებელი მკითხველისთვის, რომელსაც ამავდროულად აინტერესებს კოსმოსური თემები და ეძებს მარტივ ენაზე დაწერილ წიგნს. თუმცა თავად კოსმოლოგიის და ფიზიკის სირთულე გარანტიას ვერ მისცემს ვერავის რომ ყველაფერი გასაგები იქნება.
