In science one tries to tell people,
in such a way as to be understood
something that no one ever knew
before. But in the case of poetry,
it's the exact opposite!
Does Dirac mean (above) that poets
speak of things everyone knows
in language understood by no one?
I think it’s a peculiarity of myself
that I like to play about with equations,
just looking for beautiful mathematical relations
which maybe don’t have any physical meaning at all.
Sometimes they do.
Dirac's words express thoughtfully the viewpoints of many 20th century mathematicians and scientists.. For more quotable lines from and about him, follow this link.
