Procrastination with Coursera

Coursera is a place where you can take online courses from some of the best universities of the world (EPFL, Duke University...) and more universities are joining every month. You just have to register for the course and follow it weekly (on your own schedule). You might have assignments and everything. This is all completely free. There are so many courses that I think I didn't look at them all. Nevertheless, I point you to some that are interesting:

Medical Neuroscience
Healthcare Innovation and Entrepreneurship
Writing in the Sciences
Image and Video Processing
Digital Image Processing
Computational Methods for Data Analysis
High Performance Scientific Computing
Introduction to Data Science
