Hypotheses


Hypotheses—TEAM 3: Light and Wet

Hypotheses Team 3 proved its diversity and flexibility by establishing two hypotheses. The first centered around the central fountain. It's investigation enlisted the talents of four of our members—Bruce, Christina, Hofu, and Karen. "A dome of cooler more humid air is formed around the fountain in the center of the Great Hall."
Cool dome in section.	Cool dome in plan.
The second hypothesis focused on the lighting of the Great Hall. It's investigation could either be seen as depending on the kindness of strangers or as a means of diffusing the focus of the rival teams. Our raider, Sandy, led this operation and induced the aid of others with her sweet siren song on the poetics of illumination. "Daylighting provides sufficient illumination in the Great Hall."


Methods "A dome of cooler more humid air is formed around the fountain in the center of the Great Hall."
	Our initial attempts to find the cool, moist dome (an igloo in the warmer interior of the Great Hall?) were to use HOBO RTs strung over the fountain at the level of the first balcony (we made measurements with the fountain on and off) and to use Kestrels to measure temperature and humidity at grid points on the ground floor while the fountain was operating.
Karen discovers the wind!	Later we were seized by inspiration. While tending the HOBO line on the first balcony, Bruce began using the Raytek spot pyranometer to measure the surface temperatures of the Great Hall's floor, patches of sunlight, the fountain's edge, and the water. Karen used the Kestrel to detect a strong wind current at the edge of the fountain, which led to more detailed investigations and, ultimately, Christina's immersion in the fountain, Kestrel firmly in hand.
"Daylighting provides sufficient illumination in the Great Hall."
	Sandy used the illuminance meters and a squad of recruits to perform an illumination sweep of the floor of the Great Hall under two lighting conditions—all the lamps on (which was the default condition) and daylighting only (which turned out to be unachievable; only about half of the lamps could be turned off!).
