Chapter 4 Gravitation,rencing events in space and time: Cartesian coordinates on three orthogonal axes, either fixed or moving at constant speed in a straight line relative to the general stellar background, while time is measured by the Earth’s rotation relative to that background.

Chapter 1 Space and Time,Geometry very likely arose from the experimental need to do things like measuring land areas, but it soon went beyond this purely empirical existence to appear in the highly systematised form given to it by Euclid. It claimed its independence from the experimental facts that had given rise to it.

Chapter 3 Field Production by Relative Motion,We have seen that a coordinate system can be chosen in such a way that, in the neighbourhood of a point, the geometry will be Euclidean and the motion of free points will be uniform and in straight lines.

Chapter 5 Electric Charges,The definition of the electromagnetic field by the motion it communicates to electrically charged particles was investigated in Section 2.2. The laws describing the action of the fields on these particles were thus expressed in a form that was independent of the frames of reference used to study these phenomena.

Book 2019ng” from a “quantum primeval atom” resulting in an ever-expanding Universe with a positive cosmological constant. ..But how did the young Lemaître, essentially on his own, come to grips with the physics of Einstein? A year before his ordination as a diocesan priest, he submitted the audacious treati
