The Icu Book Terapia Intensiva: Principi Fondamentali

What do we know about the origins of the Universe, and more important, how do we know it? In a small, easy-to-read package, this book introduces you to all of the important ideas about the Big Bang and its consequences. Craig Hogan explains what happened in the early days of the universe, why we think it's expanding (and how the expansion can look the same from everyplace at once), different ways the universe could end, and the meaning of such terms as "cosmic inflation," "cosmic background radiation," and "dark matter." For everyone who has always wondered just what the cosmologists are talking about but could never find the basics explained clearly and simply, this is the book to read.

Actually, there are many different kinds of bees, most of which live relatively hidden from our view. Maybe some of us are familiar with bumblebees, but who would recognize the solitary bees, which considerably o- number the social bees? These little-observed bees are often dubbed “wild bees” to distinguish them from our honeymakers.
