Dispersion and the speed of light “So far as problems involving light are concerned‚ the electrons (in atoms) behave as though they were held by springs”.Feynman “In a microscopic but otherwise classical analysis‚ the electric field in electromagnetic radiation accelerates electrons held by springs in the atoms of a piece of glass‚ and these accelerated electrons re-radiate in all directions. The observed light is the superposition of the electric (and magnetic) fields of the incoming

High Speed Steel * High Speed Steel (HSS) refers to any of a variety of steel alloys that engineers primarily use to construct machine tool bits and blades and drill bits for industrial power tools. Materials scientists can infuse this steel with differing percentages of elements to form a variety of HSS manufacturing alloy types. While all of these different types exhibit HSS’s characteristic resistance to high-temperature‚ the properties of each alloy will vary depending on the percentage of

Describe the role of calcium in muscle contraction‚ where it is stored‚ and how it is released and recycled. Calcium storage‚ release‚ and recycling Muscles need to be malleable or have plasticity in order to function correctly. This is where calcium comes into the picture. All muscles use calcium molecules for regulatory and signaling purposes. Contraction control and relaxation control by calcium is achieved first by the activation of troponin-tropomyosin with the actin filaments. The second
