I usually don't like to get too off topic and discuss things outside of the cooking realm on this site, but I've been really enjoying a website called the Khan Academy for the last few months. After someone recommended it to me to get some ideas for enhancing the usability of StellaClinary.com, I actually got hooked on his teaching style. I've been running through the chemistry series right now to help answer some of the questions I have regarding science and chemical reactions, but all of his videos are really amazing with a great conversational tone.
Since all of the SCS community members are life long learners in all fields, not just the culinary arts, I thought I'd share this resource with you incase you haven't heard of it. Sal, the creator of this site, is "fighting the good fight" so I see him as sort of a kindered spirit. Enjoy!
