Sal Khan has done it again with this exquisitely simple yet compelling look at how a heart attack happens. This MIT graduate’s Khan Academy is a non-profit educational organization, created in 2006 with the stated mission of “providing a high quality education to anyone, anywhere”.

This video on heart disease is just one of over 3,000 brilliant (and free!) online micro-lecture tutorials at Khan Academy. So watch it already.
