The tragedy of this world is that everyone is alone. For a life in the past cannot be shared with the present.

With a background in science I am extremely interested in the meeting ground of science, theology, and philosophy, especially the ethical questions at the border of science and theology.

I think e-mail is representative of our fast food mentality in the United States, where everything has gotten faster and faster, and we're required to respond to inputs more quickly with less time for thought and reflection. I believe that we need to slow down.

And at the place where time stands still, one sees lovers kissing in the shadows of buildings, in a frozen embrace that will never let go. The loved one will never take his arms from where they are now, will never give back the bracelet of memories, will never journey afar from his lover, will never place himself in danger of self-sacrifice, will never fail to show his love, will never become jealous, will never fall in love with someone else, will never lose the passion of this instant of time.

As a scientist, I don't believe science will ever discover whether God exists. Nor do I believe religion will ever prove it.

In a world of fixed future, life is an infinite corridor of rooms, one room lit at each moment, the next room dark but prepared. We walk from room to room, look into the room that is lit, the present moment, then walk on. We do not know the rooms ahead, but we know we cannot change them. We are spectators of our lives.

I consider myself a spiritual atheist. I certainly believe there are forces bigger than ourselves, and that we should be searching, individually, for meaning in our lives. But I don't believe there's a supreme being, an intelligence that created everything.
