Special relativity is the root of many fields in glossy physics: particle physics, quantum box conception, high-energy astrophysics, and so forth. This idea is gifted right here through adopting a 4-dimensional viewpoint from the beginning. a good function of the booklet is that it doesn’t limit itself to inertial frames yet considers speeded up and rotating observers. it truly is therefore attainable to regard actual results resembling the Thomas precession or the Sagnac influence in an easy but distinct demeanour. within the ultimate chapters, extra complex issues like tensorial fields in spacetime, external calculus and relativistic hydrodynamics are addressed. within the final, short bankruptcy the writer supplies a preview of gravity and exhibits the place it turns into incompatible with Minkowsky spacetime.
Well illustrated and enriched through many historic notes, this publication additionally offers many purposes of distinct relativity, starting from particle physics (accelerators, particle collisions, quark-gluon plasma) to astrophysics (relativistic jets, energetic galactic nuclei), and together with functional purposes (Sagnac gyrometers, synchrotron radiation, GPS). moreover, the booklet offers a few mathematical advancements, corresponding to the certain research of the Lorentz team and its Lie algebra.
The publication is acceptable for college students within the 3rd 12 months of a physics measure or on a masters direction, in addition to researchers and any reader drawn to relativity.
Thanks to the geometric procedure followed, this publication must also be useful for the examine of normal relativity.
“A sleek presentation of distinct relativity needs to recommend its crucial constructions, prior to illustrating them utilizing concrete functions to express dynamical difficulties. Such is the problem (so effectively met!) of the gorgeous ebook through Éric Gourgoulhon.” (excerpt from the Foreword via Thibault Damour)
