I remember a lot of his works I had read when I was a child. Especially I'd loved "Childhood's End" and "Rendez-Vous With Rama".

I think that his achievement tells us that the science fiction is not only a sort of fictions. It can have a mission of a prediction of the future for us. It may be possible even to make our future if it was written by excellent SF writer such as Arthur C. Clarke.

We engineers have been chasing their works. Sometimes we have achieved or forestalled them even, but yet there are too many things which are waiting for us.

I pray for the future to keep attractive futures.
