10)   Lastly folks, I surrender -- I CAN'T keep up with all the nifty posts/videos Mike Lawler puts up and also read my email each week (you know, like walking and chewing gum at the same time ;-); so rather than pick out specific offerings from Mike, I'll just direct you to his page (which hopefully you already follow anyway!) and let you pick the ones most pertinent to your math interests; there's always somethin' good!:
