And the really amazing thing is, because there were so many students, it means that even if a student posed a question at 3 o'clock in the morning, somewhere around the world, there would be somebody who was awake and working on the same problem.
Lo maravilloso es que, debido a la gran cantidad de alumnos, si alguno hacía una pregunta a las 3 de la madrugada, en alguna parte del mundo alguien estaba despierto y trabajando en el mismo problema.
