NEW YORK TIMES BESTSELLER • Stephen Hawking’s closest collaborator offers the intellectual superstar’s final thoughts on the cosmos—a dramatic revision of the theory he put forward in A Brief History of Time.“This superbly written book offers insight into an extraordinary individual, the creative process, and the scope and limits of our current understanding of the cosmos.”—Lord Martin ReesPerhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. In order to solve this mystery, Hawking studied the big bang origin of the universe, but his early work ran into a crisis when the math predicted many big bangs producing a multiverse—countless different universes, most of which would be far too bizarre to ​harbor life. Holed up in the theoretical physics department at Cambridge, Stephen Hawking and his friend and collaborator Thomas Hertog worked on this problem for twenty years, developing a new theory of the cosmos that could account for the emergence of life. Peering into the extreme quantum physics of cosmic holograms and venturing far back in time to our deepest roots, they were startled to find a deeper level of evolution in which the physical laws themselves transform and simplify until particles, forces, and even time itself fades away. This discovery led them to a revolutionary idea: The laws of physics are not set in stone but are born and co-evolve as the universe they govern takes shape. As Hawking’s final days drew near, the two collaborators published their theory, which proposed a radical new Darwinian perspective on the origins of our universe. On the Origin of Time offers a striking new vision of the universe’s birth that will profoundly transform the way we think about our place in the order of the cosmos and may ultimately prove to be Hawking’s greatest legacy.

This book is aimed at everyone preparing for the ISTQB® Certified Tester ¿ Foundation Level exam based on the Foundation Level syllabus (version 4.0) published in 2023. It provides candidates with reliable knowledge based on this document and thus distinguishes itself from all the information about ISTQB® syllabi and exams on the Internet, which is often of rather poor quality and may even contain serious errors. The book expands and details many issues that are described in the new 2023 version of the syllabus in a perfunctory or general way only. According to the ISTQB® guidelines for syllabus-based training, an exercise must be provided for each learning objective at the K3 level, and a practical example must be provided for each objective at the K2 or K3 level. In order to satisfy these requirements, the authors prepared numerous exercises and examples for all learning objectives at these levels. In addition, for each learning objective, one or more sample exam questions are presented which are similar to those that the candidate will see in the exam. This makes the book an excellent aid for studying and preparing for the exam and verifying acquired knowledge.
