First, I didn't say that I thought everything already was discovered, but that the fundamental physics community doesn’t discover new things. That is due to how physics research is practiced today and has nothing to do with how much that is left to discover.

Second, even if it obviously wasn't true when Planck was told that almost everything is discovered, it doesn't say anything about the state today.

Are people working on fundamentals these days? It seems to be a forgotten art, where everyone is working at the edge of something.
