I had read this in my youth, and carried its memory for many years. Sharing my knowledge of the story with no one, for no one I knew was a big Asimov fan.

Later, while attending college, I decided to take an astronomy course as a general education class. I discovered my teacher was a big Asimov fan. He had remembered a story that he had read and shared its theme with us but had forgotten its name. I raised my hand in class and said, “Eyes do more than see.”

And for a brief moment - two Asimov fans nodded at each other.

Back then - I wasn’t a remarkable student. I was lost in many thoughts.

But I do remember this:

On the final exam for this class - for extra credit - he asked “What is answer to the Last Question?”

I smiled - then wrote my answer. The only answer. And I knew I got at least one question correct on that exam.
