Videos about the group of projects related to the problem of turbulence and sum of squares of polynomials. These projects are offered to the final year undegraduate students and to MSc students. Such projects are about four months long. The videos can also be considered as a general introduction to this area of research, for example for those who are seeking an interesting topic for a PhD. Each video is about 5 minutes long.
