  The most dramatic developments in theoretical physics in the next millennium
are likely to come when we make progress on so far unresolved foundational
questions. In this essay I consider two of the deepest problems confronting us,
the measurement problem in quantum theory and the problem of relating
consciousness to the rest of physics. I survey some recent promising ideas on
possible solutions to the measurement problem and explain what a proper
physical understanding of consciousness would involve and why it would need new
physics.
