This is one of the best courses I have taken so far. Not only the subject is essential in many scientific areas, but the course is extremely organized, facilitating follow-up. In my opinion, a few details that make this course one of the best are: (1) the introductory videos, giving a broader view of the following content; (2) the use of examples to explain the contents; (3) the review at the end of each video; (4) the PDF file available, presenting the content of the videos, exercises and solutions; and (5) the lenght of the videos, which are short enough not to make them exausting. In addition, this course is useful beyond engineering. I am actually a PhD student in chemistry and I have benefited a lot from this course!
