And yet, many people get the two confused, including physicists and mathematicians. Where the two meet, and the nature of the boundary between them, is a matter of debate — one of the greatest puzzles known to science and philosophy — but some things can be said for sure about what can and cannot be accomplished in the search for ever-better models of our world.
