FutureLearn

One of my favorite websites for online learning (or amusment) is FutureLearn.com. It offers short and free introductions to a variety of subjects.  Courses are usually 3 to 5 weeks and average about 3 hours a week of work. You can learn about everything from mobile programming to introductory Italian. Or you could inform yourself about nuclear energy, Japanese philosophy, cardiovascular disease, or Roman archaeology. Check it out.
