Who likes maths?


Go see my friend Ed give a math lecture:

In the unlikely event that you find yourself in western Massachusetts this Wednesday, come check out my talk about the concept of duality in projective geometry.

WHERE?: Lederle Graduate Research Tower, Room 1521D, UMass Amherst

WHEN?: Wednesday, March 30, 2005, 7:00 p.m.

WHAT?: Projective geometry is a non-Euclidean geometry where there is no such thing as parallel lines, and no concept of distance or angle measure. Duality is a valid concept of projective geometry where points and lines are mathematically indistinguishable from each other. This is cool because if you prove a theorem, it can be dualized to give you a new theorem that will be true (unless the theorem is self-dual to begin with)! It's like a 2-for-1 sale on mathematical concepts.
