Related to the post last week on quantum mechanics, here is a talk that got mentioned in the discussion thread. Warning: Carroll is a passionate advocate for the Many Worlds Interpretation, so don't expect a fair and balanced discussion. The video is about an hour long. http://www.youtube.com/watch?v=iXRLDatmbgA A couple of points.

I'm glad to see Apollo 8 getting some recognition. It's usually overshadowed by Apollo 11, the first mission to actually land on … Continue reading The difficulty of going to Mars

During that period, although I keenly missed our conversations, I had … Continue reading Merry Christmas
I've been thinking lately about quantum physics, a topic that seems to attract all sorts of crazy speculation and intense controversy, which seems inevitable. Quantum mechanics challenges our deepest held most cherished beliefs about how reality works. If you study the quantum world and you don't come away deeply unsettled, then you simply haven't properly … Continue reading Do all quantum trails inevitably lead to Everett?

This isn't a new theory of consciousness or anything, just my own way of making sense of what is an enormously complicated subject. That hierarchy of consciousness was as follows: … Continue reading Dogs have metacognition, maybe
