Originally‚ a device known as the ’photophone’ was used to transmit sound. This replaced Thomas .A. Edison’s ’phonograph. Since the development of optical fibres ’photo phones’ and ’phonographs’ are no longer used or needed. Optical fibres have many advantages; they enable the sound messages to carry for 50km without any need for a repeater unlike other optical communication systems‚ which need repeaters at 1km intervals. Optical fibres have replaced other methods of communication for many reasons

Taylor Gray 1/31/11 POW 6: linear nim For this game of Linear Nim you draw 10 line marks on a piece of paper and two players take turns crossing off only 1‚ 2‚ or 3 marks per turn. The person who crosses off the last mark is the winner. Firstly what I did was play a few games with my Mom and what I realized right away was that if you stopped just before the last four dashes in the game then you would always win. Since you aren’t always guaranteed of being the one who can put these dashes

Experiment 2: Microscopy & Simple Staining September 30‚ 2013 General microbiology laboratory The invention of the microscope has opened up a whole new dimension in science. By using microscopes scientists were able to discover the existence of microorganisms‚ study the structure of cells‚ and see the smallest parts of plants‚ animals‚ and fungi. Today‚ the microscope is still a commonly used tool to diagnose illness in hospitals and clinics all over the world (1)

Light From personal experience I would say light within architecture is what makes you feel uplifted as you walk into a room or a space. Light can be controlled and manipulated within certain spaces by adding light or having an absence of light. Light can completely change the dynamics of a room or space and can also have a very strong effect on the mood. Light within architecture can either be natural or synthetic‚ both creating a special experience within a room. In my research I will

1. Arm - Supports the body tube and is used for carrying the microscope. 2. Diaphragm - Controls the amount of light passing through the opening of the stage and into the microscope. 3. Stage - Supports the slide being used. You place the slide on it. 4. Mirror or Light - Reflects or shines light upward through the diaphragm to illuminate the specimen. 5. Nosepiece - Holds the different objective lenses; allows the lenses to rotate for viewing. 6. Base - Supports
