Projective geometry started life over 500 years ago in the study of perspective drawing: the distance between two points on the artist’s canvas does not represent the true distance between the objects they represent so that Euclidean distance is not the right concept.

Lecture notes on Geometry and Group Theory. In this course, we develop the basic notions of Manifolds and Geometry, with applications in physics, and also we develop the basic notions of the theory of Lie Groups, and their applications in physics.

The Radon transform is an important topic in integral geometry which deals with the problem of expressing a function on a manifold in terms of its integrals over certain submanifolds. Solutions to such problems have a wide range of applications.
