Explaining the Universe: The New Age of Physics
Princeton University Press, 05.06.2018 - 226 Seiten
In this fascinating book, John Charap offers a panoramic view of the physicist's world as the twenty-first century opens--a view that is entirely different from the one that greeted the twentieth century. We have learned that the universe is billions of galaxies larger than we imagined--and billions of years older. We know more about how it came to be and what it is. Because of physics, we live in a world of greater danger and more convenience, smaller particles and bigger ideas.

But I don't wish to suggest that all of physics is devoted to these extremes; most research is concerned with phenomena in between, some of which I will explore in chapter 12. I have benefited from numerous discussions with colleagues ...
ALTHOUGH I HAVE SCRUPULOUSLY TRIED TO AVOID MATHEMATICS in this book, I would have found it hard to convey without numbers the scale of phenomena encompassed by physics. Of all the sciences, physics is par excellence concerned with ...
Of course there is much more to the physics of today than the exploration by theory and experiment and patient observation of those phenomena at the extremes of size, the microworld of the particle physicist and the macroworld of ...
We may believe that at the most fundamental level there are some deep principles and laws that govern all the myriad phenomena of the physical world. But it is unreasonable and unrealistic to start from these fundamentals in order to ...
At any step it may be not only convenient but necessary to introduce new laws, new structures, new modes of description, the better to account for the emergent phenomena there encountered. It would be not just arrogant, but also stupid, ...
