Theoretical and experimental optical holography

The intent of this paper is to present an analysis of optical holography. Both the physical theory behind holography and the experimental techniques used in making holograms will be presented. To accomplish this goal, the paper is divided into two independent sections: the theoretical section followed by the experimental section. Each section is intended to be a complete unit. The Theoretical Section is an exposure to the theory behind holography. This consists of a review of the concepts of interference and diffraction. followed by a brief review of partial coherence. The remaining part of the Theoretical Section is devoted to the mathematical analysis of optical holography. The Experimental Section begins with an introduction to the equipment and facilities currently available for optical holography at Colby College. Holographic procedures is dominated by the description of transmission holography (v.s. reflection. or white-light. holography). After these general holographic procedures a few variations on the basic transmission hologram are presented. The experimental section will end with an introduction to holographic interferometry, a major application of holographic techniques.

Solar Panel Modeling on Suitable Roofs at Colby

With the recent construction of Colby Green and the current plans for the construction of several new buildings, the total area for future development on campus has declined. The goal of this study was to illustrate existing campus development and to determine where future growth could occur. GIS was used in determining the different soil systems on campus, the current use of the land, and the boundaries of the Colby property. The project shows what potential obstacles the college will have in attempting to expand the campus and proposes where the best options are for construction.

Gay and Lesbian Life at Colby 1969-1974

The history of a gay and lesbian student community at Colby seems to point to the difficulty of visibility. For students who were able to find others like themselves, their group of lesbian and gay friends had to remain underground. For students who were grappling with their newly found, socially stigmatized sexuality, the experience was isolating if they did not know where to find others like themselves. This paper seeks to address the social forces that kept sexually variant students from expressing their sexual identities openly on campus. Part of this difficulty is attributable to the compulsory heterosexuality assumed by general American society at the time, manifested in the silence or outright hostility directed against homosexuals. Naturally, Colby students replicated this assumption. Some of the students we interviewed seemed to internalize compulsory heterosexuality, while it was forced upon others. Religion and psychology were two methods of enforcing heterosexuality that were relevant to the people we interviewed. Another significant obstacle to visibility was Colby's location and the nature of Colby's student body. Waterville, unlike more urban cities, did not have a history of gay life, and thus an established gay community or gay identity into which one could be socialized. Colby, as a small, homogeneous and isolated space, posed difficulties in establishing a gay community as the population to draw from was small and regulated.

Monitoring Surface Displacement of the Colby Green Retaining Pond Dams

The Colby Green is a campus expansion project which began in October of 2003. The construction would result in three new buildings, additional parking, and an elliptical 75,000-squarefoot green southeast of Mayflower Hill Drive. There were also plans for the construction of three run-off management and sediment ponds below the green, to manage flooding of the green. Three drains in the green transport water to the three retaining ponds which slowly disperse water into the surrounding environment. The ponds were created by constructing earthen dams around the drain outlets. The dams are composed of soil, cobbles, and boulders procured from the surrounding excavation site. Unfortunately, earthen dams are susceptible to many types of erosion which result in their failure. In this case the potential for clay and silt from the underlying Presumpscot Formation to mix with the soil in the earthen dams raised concerns with regards to frost action. In order to monitor the surface displacement of the dams I drove 92 poles into the ground in 8 straight lines across the faces of the dams in the fall of 2005. I returned to the sites during and after the spring thaw of 2006, to check for any signs of movement resulting from frost-heave, surface creep, or any other form of mass wasting. Fortunately, there was no recordable sign of movement in the stakes across any of the retaining ponds. The dams appear to be functioning as designed.

You know how I know you're gay? : masculinity and homophobia in mainstream comedy

You Know How I Know You're Gay?: Masculinity and Homophobia in Contemporary Mainstream Comedy is a three-part senior scholars project that consists of a critical analysis of homophobic humor in contemporary mainstream comedy, an original feature-length comedy script entitled Don 't Be that Freshman, and a DVD of selected scenes from Don't Be that Freshman. The critical analysis first establishes the existence of homophobic humor in mainstream comedy and then links this homophobia to masculine anxiety, applying the ideas set forth in Michael Kimmel's essay, "Masculinity as Homophobia," to contemporary, mainstream, homosocial comedies. The paper goes on to examine audience reactions to this homophobic humor, focusing on audience members who enjoy these movies, yet consider themselves to be accepting of homosexuality and against homophobia. I discuss ways of resistance and the importance of opposing homophobic humor, and finally, I look at comedy as a potentially transgressive medium that could be used to fight homophobia and social inequality. The critical analysis, therefore, leads into Don't Be that Freshman, a film that uses progressive humor to oppose homophobia and expose the potential dangers and pitfalls of conforming to social constructions of gender. Don't Be that Freshman is a film about three pairs of college roommates in their first semester at college who become each other's first friends on campus. It is a character-driven comedy that attempts to normalize non-heterosexual sexual orientation and gender non-conformity, to advocate a type of living that does not conform to problematic social constructions and cultural ideologies, and at the same time to appeal to a mainstream audience. The film version is twenty-five minutes long and consists of ten scenes from the script.
