Luckily for our poetic sensibilities, he was persuaded to ditch the Seagull and write about a Butterfly fluttering its wings instead, and so in a lecture he gave in December 1972 he used the expression: “a butterfly flapping its wings in Brazil can produce a tornado in Texas.”, and the rest (as they say) became history.
