Whoever it was first played GF#GGGDCBDGF#G and thought it might make a merry tune to dance to could not have conceived that hundreds of years later people would still whistle the tune and associate it with the sea.
Archimedes, if he ever did jump into the bath and cry eureka! may have thought he had discovered something people would think about for a long time afterwards but was unlikely to have realised he had given rise to the expression "eureka moment".
Delibes could have had no idea that his Flower Duet from Lakme would be disseminated to the masses via digital media to advertise flying machines, or Bach (here I show my age) that the Air from his 3rd Orchestral Suite would be used to advertise cigars.
In one way, the most interesting of these examples, because its creator is the least famous, is that of the Hornpipe. We have no idea who thought it up, anymore than he or she had that we would still be whistling it. I'm thinking, I suppose, of the "butterfly effect". We usually think of it in relation to time travel - to going back in time and changing history. I'm thinking though, of the butterfly effects that have happened in the past and happen in the present, without the help of time machines, how what we say or do effects not only the moment in which we say or do it but the future as well.
Whistle a new tune and if it's catchy you might have invented a cultural virus that'll knock around for centuries.
Or - I have heard it said that a joke told in a playground in London will be told within 40 minutes in Newcastle. Try and think up as good a joke as you can.
