The Importance Of A Steady Source Of Light - 936 Words

For thousands of years, man had used the sun as the main source of light during the day and fire by night. Light progressed from crude shells filled with moss or animal fat to pottery vessels filled with whale oil2. In 1802, Humphry David placed two wires from a battery to a piece of carbon and created the first electric light. While it did not produce light for very long and was too bright for everyday use, it gave hope to inventors everywhere who believed that a steady source of light could be created3. It was not until almost seventy years and countless hours of research later, that the modern electric light came into existence. This discovery literally changed the world. Thomas Edison recognized the importance of a steady source of light and is credited with the first of several patents on a bulb that used a carbonized bamboo filament. But perhaps his most important contribution was to recognize the future of the light bulb and he went on to invent a method of transporting electric current and tracking electric usage. Other inventors took the light bulb to its next level with the invention of the tungsten filament and how to use an inert gas like nitrogen inside the bulb to increase efficiency4. The first light bulb was called an incandescent bulb. This light bulb was originally produced by hand, but now the manufacturing process is entirely automated and light bulbs are produced in a machine that can produce more than 50,000 bulbs per hour5.

Thus the method of manufacture is highly important as the study showed directl y compressed pellets had better dissolution profiles. Also it shows the importance of the choice of excipients as pellets manufactured via wet granulation in the absence of microcrystalline cellulose showed similar release to that of directly anhydrous theophylline.
