TED Talks　から　「18分でたどるビッグヒストリー」宇宙の誕生から今に至るまでの、壮大な歴史の話です。
抜粋：
We are blessed with a language, a system of communication, so powerful and so precise that we can share what we’ve learned with such precision that it can accumulate in the collective memory. And that means it can outlast the individuals who learned that information and it can accumulate from generation to generation.
