I feel like my geeky-minded son (and my husband) would find this fascinating... but my brain just feels like it is going to explode. Why am I reading so much science-techie stuff today?

I LOVE your quote

If you can't explain it simple enough,
you don't understand it well enough.

Because that just nails it SO well! I love it when someone can explain things in my language.

Awesome post. I wish I'd had this when I was teaching my kids years ago!
