The Mathsters is series of short video lectures introducing “proper” mathematics starring Dr. Eugenia Cheng of the University of Sheffield, UK. These are aimed at 16-18 year olds who want to stretch themselves towards undergraduate level mathematics, and interested adults who have little or no experience of formal mathematics.

Dr. Cheng is a dynamic and engaging speaker. She has a rare gift for making complex mathematical topics clear and approachable. Her enthusiasm for mathematics shines!

I absolutely love these videos. Your style is refreshing. You make the subject extremely easy to understand.

I would love to see you teA h a few lessons on Group theory or just abstract algebra in general. Thanks.
