We thus define the notion of tangent boost along a worldline. We also introduce a matrix of the Lie algebra which, together with the tangent boost, gives the whole dynamical description of the considered system acceleration and Thomas rotation. After studying the properties of Lie algebra matrices and their reduced forms, we show that the Lie group of special Lorentz matrices has four one-parameter subgroups.

These tools lead us to introduce the Thomas rotation in a quite general way. At the end of the paper, we present some examples using these tools and we consider the case of an electron rotating on a circular orbit around an atom nucleus.
We then discuss the twin paradox and we show that when the one who made a journey into space in a high-speed rocket returns home, he is not only younger than the twin who stayed on Earth but he is also disorientated because his gyroscope has turned with respect to earth referential frame.

Date: April 28, Date: January 19, Generalized general and special relativity in the presence of the gravitation, related to the space-time curvature. Date: May 18, Date: March 28, We have a dedicated site for Germany. Special relativity is the basis of many fields in modern physics: particle physics, quantum field theory, high-energy astrophysics, etc.
This theory is presented here by adopting a four-dimensional point of view from the start. It is thus possible to treat physical effects such as the Thomas precession or the Sagnac effect in a simple yet precise manner. In the final chapters, more advanced topics like tensorial fields in spacetime, exterior calculus and relativistic hydrodynamics are addressed.

In the last, brief chapter the author gives a preview of gravity and shows where it becomes incompatible with Minkowsky spacetime. Well illustrated and enriched by many historical notes, this book also presents many applications of special relativity, ranging from particle physics accelerators, particle collisions, quark-gluon plasma to astrophysics relativistic jets, active galactic nuclei , and including practical applications Sagnac gyrometers, synchrotron radiation, GPS. In addition, the book provides some mathematical developments, such as the detailed analysis of the Lorentz group and its Lie algebra.
The book is suitable for students in the third year of a physics degree or on a masters course, as well as researchers and any reader interested in relativity. Thanks to the geometric approach adopted, this book should also be beneficial for the study of general relativity.
