Chris has been watching math videos (huh?!), so I tuned in for a few, including this video introducing differential equations. They’re really easy to watch, follow, and learn from, and the instructor is an absolute delight. It’s impressive to see lessons that are considered ‘upper level’ math presented with such ease and in such manageable chunks. I am sad that my last math class was 8 years ago; these mini-lessons are just enough to fill that void for awhile longer!

Even if you’re not a math person, there are videos for you! The Khan Academy is an online-based nonprofit with a mission to make quality education available to everyone. They have nearly 4,000 videos on topics from biology, to animation, to finance, to history. I love the mission and the execution; two thumbs up. Now go learn about differential equations!

Believe it or not, these are old images in which Guillaume Duchenne was attempting to find the perfect smile through electrodes targeted at specific muscles. He articulated this quest: The “Duchenne smile” is a genuine one, one that seems happy and friendly. It’s the result of two different groups of muscles working together. Cheek muscles turn the lips up in a voluntary maneuver that can be faked. But the muscles under your eyes that crinkle the skin to the outer side of each eye are involuntary, and they don’t necessarily start working just because you need to make a good impression at a job interview. Only the two combined really look genuine. When you smile with just your lips, you look like you’re either faking or in pain. Recently however, more people can fake a ‘perfect smile’. Are we as a society becoming more fake? Or less aware of the nuances of expression? Or (worst of all) less joyous?

Cows: what you never knew. Check out that stomach!  All this and more unnecessarily wonderful knowledge at the website that knows everything (or that I at least assume to be generally correct). Wikipedia gives different sorts of info; I’m pretty sure you never actually have to meet a cow if you consume both fact-laden webpages. But that would be the saddest thing, so go meet a cow.
