Non, je ne regrette rien (Inception)

Edith Piaf sang this beautiful song. I went to see Inception at Reforma 222, in Mexico City. Christopher Nolan, made a good choice. No, I don't regret anything.

More on ...rien.

Cobb does not regret anything either, he comes to terms with himself at the end.

Two issues I want to mention here, one I already wrote something about here recently. Consciousness, the other is "The Renormalization Group."

Consciousness is a social construct, if enough people claim something we start to believe it. Cobb gains his freedom by sticking to "reality," at the end we wonder when the top doesn't seem to do what I was expecting, I was expecting it to fall; but yes it does not fall, so we have to keep skepticism alive. Is this reality or not? Calderón de la Barca wrote many years ago, ``Life is a Dream.''

Kenneth Wilson received a Physics Nobel Prize, among other things for his work on critical phenomena and the Renormalization Group.

In the movie, every layer of dream state, there were four, goes faster and faster. One minute at a high level could be hours at a lower level. Each level has its clocks, and they don't have the same scale. One may be tempted to say slower, and slower. The issue is that one high level second corresponds to many low level seconds. More things happen, down there in deep sleep, than in one of the high level seconds.

Feynman said many years ago now: "There's plenty of room at the bottom.."
