Electric and Magnetic Aspects of Gravitational Theories

Publisher: arXiv 2011
Number of pages: 240
This thesis deals with the construction of conserved charges for asymptotically flat spacetimes at spatial infinity in four spacetime dimensions in a hopefully pedagogical way. As a first motivation of this work, it highlights the difficulties one encounters when trying to understand the gravitational duality, present at the linearized level, in the full non-linear Einstein's theory or even just in an asymptotic regime of it.

A book for the inquisitive reader who wishes to understand the main ideas of special and general theory of relativity. Only a modest understanding of high school mathematics is required. A formal account of special relativity is given in an appendix.

Assuming no prior knowledge by the reader, the book raises specific, hitherto overlooked questions about how time works, such as how and why anyone can be made to be, at the very same instant, simultaneous with events that are actually days apart.

Notes from the lectures on Quantum Cosmology and Baby Universes. The lectures covered quantum mechanics for closed systems, generalized quantum mechanics, time in quantum mechanics, the quantum mechanics spacetime, and practical quantum cosmology.

What is this theory of relativity and why is it so important? The mathematics of it are too much for most of us, but we can get some notion of it by a familiar illustration. A discussion of the more intelligible features of the theory of relativity.
