Opis

This book provides an accessible introduction to astronomy and general relativity, aiming to explain the Universe, not just to describe it. Written by an expert in relativity who is known for his clearly-written advanced textbooks, the treatment uses only high-school level mathematics, supplemented by optional computer programs, to explain the laws of physics governing gravity from Galileo and Newton to Einstein.

Recenzje

'Altogether, this is a very illuminating work … The general reader will profit from the well thought-out representation, and the specialist will find many original new view-points for looking at well-known facts.' General Relativity and Gravitation
