New Theories of Everything
Will we ever discover a single scientific theory that tells us everything that has happened, and everything that will happen, on every level in the Universe? The quest for the theory of everything - a single key that unlocks all the secrets of the Universe - is no longer a pipe-dream, but the focus of some of our most exciting research about the structure of the cosmos. But what might such a theory look like? What would it mean? And how close are we to getting there? In New Theories of Everything, John D. Barrow describes the ideas and controversies surrounding the ultimate explanation. Updating his earlier work Theories of Everything with the very latest theories and predictions, he tells of the M-theory of superstrings and multiverses, of speculations about the world as a computer program, and of new ideas of computation and complexity. But this is not solely a book about modern ideas in physics -- Barrow also considers and reflects on the philosophical and cultural consequences of those ideas, and their implications for our own existence in the world. Far from there being a single theory uniquely specifying the constants and forces of nature, the picture today is of a vast landscape of different logically possible laws and constants in many dimensions, of which our own world is but a shadow: a tiny facet of a higher dimensional reality. But this is not to say we should give up in bewilderment: Barrow shows how many rich and illuminating theories and questions arise, and what this may mean for our understanding of our own place in the cosmos.

Impossibility
In Impossibility, John D. Barrow--one of our most elegant and accomplished science writers--argues convincingly that there are limits to human discovery, that there are things that are ultimately unknowable, undoable, or unreachable. Barrow first examines the limits of the human mind: our brain evolved to meet the demands of our immediate environment, and much that lies outside this small circle may also lie outside our understanding. He investigates practical impossibilities, such as those imposed by complexity, uncomputability, or the finiteness of time, space, and resources. Is the universe finite or infinite? Can information be transmitted faster than the speed of light? The book also examines deeper theoretical restrictions on our ability to know, including Godel's theorem, which proved that there were things that could not be proved. Finally, having explored the limits imposed on us from without, Barrow considers whether there are limits we should impose upon ourselves. Weaving together this intriguing tapestry, Barrow illuminates some of the most profound questions of science, from the possibility of time travel to the very structure of the universe.

100 essential things you didn't know you didn't know about math and the arts
\"At first glance, the worlds of math and the arts might not seem like comfortable neighbors. But as mathematician John D. Barrow points out, they have a strong and natural affinity--after all, math is the study of all patterns, and the world of the arts is rich with pattern. Barrow whisks us through 100 thought-provoking and often whimsical intersections between math and many arts, from the golden ratios of Mondrian's rectangles and the curious fractal-like nature of Pollock's drip paintings to ballerinas' gravity-defying leaps and the next generation of monkeys on typewriters tackling Shakespeare\"--Dust jacket flap.

The Artful Universe Expanded
John D. Barrow looks at the relationship between the way our understanding of the universe reflects the ways in which evolution has shaped our brains, and our expression of that understanding in science, maths and art.

ثوابت الطبيعة من ألفا إلى أوميغا
هذا الكتاب رحلة ممتعة وشيقة للجميع في عالم الأعداد والظواهر الكونية المرتبطة بها، واستكشاف في فيزياء الكون والقوانين الناظمة له، التي تكفل بقاءه على هذا النحو منذ نشوئه والتوازن الدقيق بين قوى الطبيعة. لكن الفكرة الأهم التي يسعى الكتاب إلى استنتاجها هي أن نشوء الحياة كان مصادفة بحتة خلفتها هذه الثوابت في تاريخ الكون، فلو اختلت هذه الثوابت عن قيم دقيقة محددة لما وجدت الحياة على الأرض. يتطرق الكتاب، أيضا، إلى عدد من القضايا العلمية والفلسفية مثل الأكوان المتعددة، ومكانة الإنسان في تاريخ الكون، وعمر الكون والتاريخ الافتراضي والمبدأ الأنثروبي، بالإضافة إلى مساهمات كثير من العلماء المشهورين والمغمورين في تطور الفهم البشري للكون والطبيعة، وكل ذلك بلغة سلسة ومبسطة وبأسلوب أدبي رشيق يجعله يحقق المتعة والفائدة.
