linkedin,
although i am confident that you shouldn't ask such question, but the best source for you is wikipedia.com, then put in the keyword in your mind
You may try coursera.com which is a free web portal where courses from top universities are available for free. I am not sure if any particular course of this sort is available, but there is a course - Finance for non-finance professionals. I understand this is not the course which you are looking for, but in the future there may be some courses on your desired subject and its worth visiting the site occasionally for checking it out.
Hope this helps.
