- Abstract:
An interactive applet and associated web page that the definition of the center of a regular polygon. The applet presents a regular polygon, where the user can drag any vertex to resize it, and change the number of sides. The center point is shown to always be the point equidistant from every vertex. Applet can be enlarged to full screen size for use with a classroom projector.

- Abstract:
An interactive applet and associated web page that provide step-by-step instructions on how to find the center of a circle using any right-angled object, such as a piece of paper. The method uses Thales Theorem to draw two diameters, which intersect at the circle center. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector.

- Abstract:
An interactive applet and associated web page that provide step-by-step instructions on how to find the center of a circle using only a compass and straightedge. The method used involves constructing the perpendicular bisectors of two random chords. The bisectors intersect at the center of the circle. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector.

- Abstract:
This course explores how social theories of urban life can be related to the city's architecture and spaces. It is grounded in classic or foundational writings about the city addressing such topics as the public realm and public space, impersonality, crowds and density, surveillance and civility, imprinting time on space, spatial justice, and the segregation of difference. The aim of the course is to generate new ideas about the city by connecting the social and the physical, using Boston as a visual laboratory. Students are required to present a term paper mediating what is read with what has been observed.
