Nima Arkani-Hamed
We shall not cease from exploration
And the end of all our exploring 
Will be to arrive where we started
And know the place for the first time.

It's a challenging talk, but I think it's worthwhile trying to digest it.



Thanks. I found that interesting. In case anyone is teetering on the brink of watching it, it is definitely aimed at a lay audience and the delivery is very un-dry.

I thought his response to a question about consciousness and the role it plays in quantum measurement was interesting (at about 1:24:25). He cut the questioner off quite abruptly and asserted that "there is nothing interesting going on in the foundations of quantum mechanics ... everything there is fully, completely understood within the ordinary logic of quantum mechanics."

As he is actually arguing that the foundations of quantum mechanics - like those of space-time - lie in the field of "amplituhedron theory" that he is working on, I assume his vehemence is directed against any role of consciousness in the process.
