Weekend Story-The Answers Have Changed

In 1942, Albert Einstein was teaching at Princeton University, and he once administered an exam to his 2nd-year students of Theoretical Physics.

Later in the day, he was walking on the campus with one of his senior assistants when all of a sudden, the assistant looked at Albert Einstein and said, ” Dr. Einstein, this exam that you just gave the senior class of Physics students, isn’t it exactly the same exam you gave them one year ago?”

“Yes, Yes, you are right,” chimed Dr.Einstein ” It is the same exam.”

“But Dr. Einstein, why would you give the same exam two years in a row to the same students?” asked the puzzled student.

“Because the answers have changed,” responded Dr. Albert Einstein, in all seriousness.
