My friend Albert Einstein told me the following about quantum theory: if the important thing is to ask the right question, he said, you must always try to find out what has been left out of the question, because that is the important thing at the end of the day.
Mon ami Albert Einstein me disait la chose suivante sur la théorie quantique: si poser la bonne question est une chose importante, il faut toujours tenter de trouver ce qui a été exclu de la question, car c’est finalement cela le plus important.
