You are being downvoted, but this is not as off-topic as it may seem. Simone Weil had a brother, André Weil. You may not know his name on the top of your head, but I guarantee you that you've heard of the pseuodonym he created together with some other mathematicians: Nicolas Bourbaki. I'm sure Weil and/or Bourbaki has lots to say about these topics.
