Umberto Lombardo,Gianluca Giuliani,Yifei Niu Niño could shift blame from underlying causes of vulnerability to a hazard-centric viewpoint. Instead of focusing on one hazard-influencing phenomenon, opportunities should be created for the Pacific region to tackle wider DRR and development concerns.

This study concludes that some of these impacts—including coral bleaching, drought (in the northern islands), flooding (in some seasons), infectious disease, and fishery an

,Space–Time Symmetries and Classical Observables,Quantum Mechanics, introduced and developed at the beginning of the last century, represents a revolution of the ideas and laws of Classical Mechanics.

Superposition Principle,Classical Mechanics endorses the sharp separation between particle and wave phenomena in the macroscopic world, the former being governed by Newton’s laws and the latter by Huygens–Fresnel’s laws.

Elementary Phenomena,After having mastered the formalism of quantum mechanics, we address the application of the principle of superposition to simple phenomena, that involves either light or particles. Firstly, we shall consider the interference and diffraction of X-rays or particles from periodic structures such as crystal lattices, which are . for such phenomena.

Harmonic Oscillations,Harmonic oscillations are frequently encountered in several fields of physics. Remarkable examples are the electromagnetic waves, lattice vibrations in solid state physics, giant resonances in nuclear physics, neutrino oscillations in elementary particle physics.

,Approximations to the Stationary Schrödinger Equation,The Schrödinger equation can be solved without approximations only for a few simple systems. As a matter of fact, each physical system requests a specific method of approximation, nevertheless, some general methods have been devised to be employable for particular classes of systems.
