We shall explore several fields in mathematics and sciences. We do not attempt go through all the little tiny details. But we shall try to give enough self-contained references so that the interested students can make up by themselves. From time to time, we also invite speakers from different disciplines to give lectures.In this course, we also require students to give presentations in class. In doing this, the students gets more involved in the material. Some of the selected topics are preparations for a big exhibition of mathematics which is supposed to take place from the coming December and will last for several months. We hope after training in this class some of the students can help to explain mathematics to general audience in the fore mentioned exhibition.
