Optics-Physics at the Speed of Light

A luminary ray of mystique and romance. One that persists to confound and to astound, to gleam and shower all with its radiant luminosity. This familiar phenomena, bequeathed by nature and synthesised by that of man continues on a persistent basis to stagger and bewilder, not as a direct result of its refractory or reflective dynamics but rather its indispensable mantle. Light is ever ubiquitous and elementary yet the optic principles that deploy the image of a dynamic and versatile phenomenon prove paradigm-shifting. The inception of modern physics has foreseen myriad indications for optics; from the classical canons of refraction and reflection to the quantum constancy of photons to the boundless utility of lasers and optical fibre. Optics seeks the laws and axioms that drive and facilitate light; the 'bending' of a straw in a glass is a simple happening, but the mathematically sound, physically oriented and thermally dynamic explanation proposed by optics unveils a mechanism of infinite complexity and diversity. The laws of nature seem to articulate in synchrony, playing unanimously to a symphony; light remains the culmination of such a symphony, the crux of illumination and the subject of inquiry for optics. Understanding light was confined to the parameters of Newtonian particle theory until the advent of relativity and the elucidation of photons entered the scientific repertoire. It is the successive stances of optics that has redefined the approach to light and illumination, while bound by the universal laws of physics. Light is nothing short of dynamic and sprawling, it is our reduction of its form and function that has bequeathed the spectrum of electro-magnetism and forged new frontiers as to its velocity and insurmountable versatility. A preeminent instance of this versatility would be the oculi, commonly recognised as the eyes, centered on the concept of diffraction via a lens of biological tissue that warps light into a curvature prior to its conversion to nervous impulses. While the eyes may remain an inherently biological conception of light, the physics at the heart of the optic moment is both paramount and uncompromising. The advent of the lens as a sprawling optic application has reinforced the prospect of utility. Lenses, whether concave or convex, focus parallels of light rays upon a focal point in a fashion of diffraction. It remains synergy of light and the laws of physics that has surmounted gaps in understanding such dynamic phenomena and deployed a methodical means of first-hand investigation. And above all descriptors of physics and dynamics is an aesthetic pleasure that enriches the conception of light, divisible into its inherent spectrum of shades and hues; an elegant and alluring entity, abundant in beauty and charm. For all of natures laws lay hid in night, until optics was and all was light!
