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

wavelength of light. Because the velocity of light in air is always greater than that through a liquid‚ the refractive index is a number greater than 1; for example‚ hexane n20D 1.3751. The superscript 20 indicates that the measurement was made at 20 oC‚ and the subscript D refers to the yellow D-line of a sodium vapor lamp‚ light with a wavelength of 589 nm. The measurement is made with a refractometer using a few drops of liquid. Compensation is made within the instrument for the fact that white

P H A R M AC E U T I C A L application note Checking the accuracy of PERKIN-ELMER POLARIMETERS H. Stenz‚ Bodenseewerk Perkin-Elmer GmbH Abstract Quartz standards‚ sucrose solutions and optically active pure liquids are discussed as potential polarimetry standards. It is suggested to preferably use quartz standards for checking the accuracy of Perkin-Elmer polarimeters. Quartz standards are absolutely stable‚ have a high accuracy and are easy to use. For laboratories working in an environment

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
