When I was invited to give this talk  a couple of months ago, we discussed a number  of titles with the organizers, and a lot of different items were  kicked around and were discussed.
عندما دُعيت لإلقاء هذة المحادثة قبل بضعة شهور، ناقشنا عدداً من العناوين مع المُنظمين، و تم طرح و مناقشة العديد من  البنود المختلفة .
