The below TED Talk is awe-inspiring:
MIT researcher Deb Roy wanted to understand how his infant son learned language — so he wired up his house with video cameras to catch every moment (with exceptions) of his son’s life, then parsed 90,000 hours of home video to watch “gaaaa” slowly turn into “water.” Astonishing, data-rich research with deep implications for how we learn.
I would give so much to have a map of my very first words in chronological order. What a lucky little boy.
