Brought together in one focused and exclusive treatment, this book provides an elementary introduction to the important role and use of the least action principle and the resulting Lagrange’s equations in the analysis of the laws that govern the universe. It is an ideal complimentary resource to accompany undergraduate courses and textbooks on classical mechanics. Features: Uses mathematics accessible to beginners Brings together the Principle of Least Action, Lagrange's equations, and variational principles in mechanics in one cohesive text Written in a clear and easy-to-understand manner

Inflativity is a groundbreaking new theory of universal 4D inflation that solves many of the fundamental problems currently existing in modern Physics. The reasoning follows from simple fundamental principles and develops one's thorough understanding and the revelatory implications. Requiring only a basic understanding of Physics, one is taken on an amazing journey that ultimately leads to a full explanation of the origin of time. Along the way we solve some of the eternal questions such as: Why is the speed of light always constant? What really is gravity? Does dark matter actually exist? How can particles behave like waves? Does God play dice? The conclusion amounts to a compelling new insight into the very nature of reality.

Observations of pulsar timing suggest that glitches and post-glitch behavior are due to variable coupling between the superfluid and normal components in neutron stars. A rotating superfluid is threaded by quantized vortex lines which, in the inner crust of a neutron star, can pin to the nuclear lattice that coexists with the superfluid. The dynamics of the superfluid is described by the motion of these lines. Vortices overcome their pinning barriers through thermal activation or quantum tunneling, and "creep" slowly outward under forces created by the superfluid flow. To the extent that vortices remain pinned, the superfluid retains its angular momentum as the crust slows through interactions with its environment. Catastrophic unpinning of vortices could lead to sudden dissipative coupling between the superfluid and the crust thus creating glitches, while post-glitch relaxation is likely due to the recovery of the vortex creep rate to the steady state. To explore this model, we develop a microscopic quantum theory for vortex unpinning and creep based on first principles. In considering a range of vortex pinning parameters obtained theoretically, we estimate the vortex creep rate throughout the inner crust. We make predictions for the form and time scales of post-glitch response, and compare with timing data from the Vela and Crab pulsars. In the second part of the thesis, we study the quark-hadron phase transition in the early universe assuming the transition is first order. First order phase transitions occur dynamically; a bubble of the new phase is nucleated which expands at the expense of the old phase. Using relativistic hydrodynamics, we study the propagation of hadron bubbles with surface tension. We demonstrate the hydrodynamic instability of deflagration processes, and discuss possible consequences for baryon concentration effects relevant in later nucleosynthesis.
