NOT BASEBALL

I have been busy at work lately.  So, the blog has suffered.

I wanted to share a link that a colleague shared with me.  Khan Academy has videos on many topics including math from developmental math, through algebra to calculus.  They are lectures with low production value.  The ones I watched were accurate and would serve as decent reviews or references.  I would certainly use them before spending time making a video on something other than a specific question.
