Optical Properties of Quasicrystals: Negative Refraction Quasicrystals‚ or crystals that display the unusual property of non-periodicity (while remaining ordered)‚ were discovered in the 1980s by Dan Shechtman. A highly controversial topic‚ Shechtman did not produce a paper describing them for over two years after their discovery. However‚ within the past 30 years‚ the scientific community has come to accept them‚ reproduce them for study‚ and even award Dan Shechtman with a Nobel Prize for their

Creating optical illusions is an art in itself. And portraying an optical illusion into an aesthetically pleasing work of art requires a fair bit of sense and sensibility. Expressing your artistic skills through illusions calls for the stroke of genius. Literally. In today’s post featured artists have shown their mastery of artistic shapes and colors to produce enlightening as well as scary optical illusions. The post also includes some awesome 3D optical illusions and Jesus optical illusion pictures

Abstract α-amylase was immobilized covalently on iron oxide magnetic nanoparticles. The synthesis of magnetic nanoparticles was done by the coprecipitation conventional method. The chemical composition and particle size of the synthesized particles was confirmed via X-ray diffraction. Tyrosine‚ Lucien and chitosan and glutaraldehyde were investigated to make a covalent binding between the iron oxide magnetic core and the immobilized enzyme. Immobilization using chitosan and glutaraldehyde show

LIST OF ACRONYMS/ABBREVIATIONS 1. INTRODUCTION 1.1 Research Motivation Laser induced damage is of interest in studying the transmission of large amounts of optical energy through step-index‚ large core multimode fibers. Optical fibers often have to be routed around objects when laser light is being transmitted between two locations which require the fiber to bend into a curve. Depending on how tight the bend is‚ this can result in transmission

I did a little research on this‚ but not much. "A good essay‚ but a few grammer errors." I corrected them in the one I submitted to you. Optical Illusions Have you ever looked at something‚ and it appears normal‚ but after a few minutes of thinking about it‚ you find it distorted? The brain and eyes are two organs that work together constantly. Two sources feed visual information to the brain:the eyes and the brain’s memory of past experience. Usually the information is clear enough‚ and you have
