An Introduction to the Relativistic Theory of Gravitation (Hardcover, 2008 ed.): Petr Hajicek An Introduction to the Relativistic Theory of Gravitation (Hardcover, 2008 ed.)

The contemporary theoretical physics consists, by and large, of two independent parts. The rst is the quantum theory describing the micro-world of elementary p- ticles, the second is the theory of gravity that concerns properties of macroscopic systems such as stars, galaxies, and the universe. The relativistic theory of gr- itation which is known as general relativity was created, at the beginning of the last century, by more or less a single man from pure idea combinations and bold guessing. The task was to "marry" the theory of gravity with the theory of special relativity. The rst attempts were aimed at considering the gravitational potential as a eld in Minkowski space-time. All those attempts failed; it took 10 years until Einstein nally solved the problem. The dif culty was that the old theory of gravity as well as the young theory of special relativity had to be modi ed. The next 50 years were dif cult for this theory because its experimental basis remained weak and its complicated mathematical structure was not well understood. However, in the subsequent period this theory ourished. Thanks to improvements in the te- nology and to the big progress in the methods of astronomical observations, the amount of observable facts to which general relativity is applicable was consid- ably enlarged. This is why general relativity is, today, one of the best experimentally tested theories while many competing theories could be disproved. Also the conc- tual and mathematical fundamentals are better understood now.

Jeder von uns kennt exzellente Teams: Wir gehen mit Vorfreude und Leichtigkeit zur Arbeit. Wir bringen Motivation und Ideen mit. Es gibt dort eine fröhliche, offene und robuste Kommunikation - und die Bereitschaft, jederzeit freundschaftlich zu streiten, wenn es dem besseren Ergebnis dient. Gute Leistung entsteht so fast von allein. Das macht die Magie großartiger Teams aus. Wie baut man ein exzellentes Team auf? Exzellenz und Hochleistung sind kein Geheimnis - wenn Führungskräfte und Teams das Wissen und das Können haben: Wissen: Wie verhalten sich Menschen in Organisationen? Neurobiologie und Sozialwissenschaften haben mittlerweile gut erforscht, welche Muster menschlichen Verhaltens in Teams und Organisationen immer wiederkehren. Zu verstehen, wie wir in der Gruppe ticken, ist die Grundlage für eine erfolgreiche Zusammenarbeit. "Exzellente Teams - Das Geheimnis von Hochleistung in 8 Schritten" fasst kompakt zusammen, was wir heute über die Funktionsweise herausragender Teams wissen. Können: Weil sie an die wiederkehrenden Verhaltensweisen und Bedürfnisse von Menschen in Teams anknüpfen, funktionieren die "8 Magic Skills", die dieses Buch empfiehlt, so zuverlässig. Mit ihrer Hilfe kann jedes Team Schritt für Schritt Sicherheit, Verlässlichkeit und Vertrauen aufbauen - und damit eine Kultur der Exzellenz. Meisterschaft: In Zeiten rascher und unberechenbarer Veränderungen sind selbsttragende und bewegliche Teams der Schlüssel zum Erfolg. Zur Meisterschaft gelangen herausragende Teams, indem sie sicher miteinander navigieren: Ihr Wegweiser sind der Sinn und die Bedeutung, die sie ihrer Arbeit geben. Auf ihrer gemeinsamen Reise durch Ungewissheit und Veränderung lernen sie ständig dazu. Das macht sie reaktionsbereit, leistungsfähig - und am Ende exzellent. Wissen, Können, Meisterschaft: Jedes Team und jede Führungskraft kann eine Gruppen-Kultur aufbauen, die Exzellenz und Hochleistung ermöglicht. "Exzellente Teams - Das Geheimnis von Hochleistung in 8 Schritten" zeigt, wie ein Team heranwächst, das sich wie ein intelligenter Schwarm bewegt und Leistungen erbringt, die alle Beteiligten glücklich machen.
