science has now been for a long time - and to an ever-increasing extent - a collective enterprise. Actually, new results are always, in fact, the work of specific individuals; but, save perhaps for rare exceptions, the value of any result depends on such a complex set of interrelations with past discoveries and possible future researches that even the mind of the inventor cannot embrace the whole.
Simone WeilFor when two beings who are not friends are near each other there is no meeting, and when friends are far apart there is no separation.
Simone Weil
