(10) Sit next to a beautiful, attractive lady for 2 hours, you will see time has flown away !! Now walk on the street for 2 minutes in the middle of summer heat, it will feel like you are walking for eternity !! Albert Einstein.
(11) I always oppose testing. Exams kill students' curiosity. In no way should more than two exams be given in the life of a student. I used to organize seminars for the students. If the students listened attentively, I would give them a diploma. —— Einstein.
