If you just casually look at a baby, it doesn't look like there's very much going on there, but they know more and learn more than we would ever have thought. Every single minute is incredibly full of thought and novelty. It's easy as adults to take for granted everything it took to arrive at the state where we are.

Babies and young children are like the research and development division of the human species, and we grown-ups are production and marketing.

If you just, pretty much, take a random 15-month-old, just sit and watch them for 10 minutes and count out how many experiments, how much thinking you see going on, and it will put the most brilliant scientist to shame.
