Topology is one the most important and interesting subjects in mathematics. Since topology is is hardly taught at school, I thought I'd make some lessons about it. The material is accessible to everybody, and will hopefully be educational for children and adults alike. Some of these problems are great for expanding the mind and practicing visualization.

The projective plane is a beautiful, fundamental and peculiar surfaces. In this video we take a practical approach towards visualizing the `twisted sphere' using simple models.
