A Walking Tour Through Projective Spaces
In this informative and elementary talk, we will discuss glass tabletops,
crystal balls, and railroad tracks. We will learn about why lines can be
points, when a hole dug to China can get you back where you started, and how to
compactify the real line by enlarging it. I will dip into algebraic geometry
via a worked example illustrating Bezout's theorem, then venture far beyond my
competence by mentioning combinatorics, topology, and number theory, then
finally return to my domain of expertise with an application to computer
graphics.
