“What is time? It would be nice if we could find a good definition of time. Webster defines ‘a time’ as ‘a period,’ and the latter as ‘a time,’ which doesn’t seem to be very useful. Perhaps we should say: ‘Time is what happens when nothing else happens.’ Which also doesn’t get us very far. Maybe it is just as well if we face the fact that time is one of the things we probably cannot define (in the dictionary sense), and just say that it is what we already know it to be: it is how long we wait!” – Richard P. Feynman, The Feynman Lectures on Physics, Vol. I (emphasis in original)
