: "The mind/brain is the most complex organism in the universe and physics can tell us nothing about it."
Trained as a physicist I am instantly motivated to say, "Well, that's not entirely true . . .", because it isn't entirely
true, but I readily agree, having studied neurobiology from a computational perspective in grad school, that it's as near true as makes no real difference.
I've mentioned before, possibly not here, that in the late 1980s and early 1990s, many physicists were leaving physics because of several related and co-dependent facts about funding, big science, and the growing tendency of physicists on the cutting edge to spiral off into string-land, never therefrom to return.
At the same time, it was the eve of The Decade of the Brain ("You're giving us a whole decade
to figure out the brain? How generous!"
), and so physicists, thinking themselves clever, began to pile on the bandwagon of computational neuroscience, arrogant as ever.
Watching the neurobiologists reach for their wastebaskets to throw up into was truly amusing -- not least because I was doing exactly what they found so objectionable (and rightly so).
Notably, the interesting physics is no longer so simple (and, if truth be known, the "simple" physics was always computationally quite hellaciously complex -- one reason Feynman gets props, as his best-known contribution, those loopy-wiggly diagrams for QED, was little more than a bookkeeping mechanism to make it remotely possible for physicists to keep straight all the cascading sums of integrals over all possible paths through spacetime of all possible particles involved in the simplest of high-energy interactions).
