In physics, to be in two places at the same time would be a miracle; in politics it seems not merely normal, but natural.

The principle that light can be in two places at the same time is absolutely extraordinary.

I'm very particular but very thrifty at the same time.

In view of our public pledges, we public officials can never again go before the public merely promising election reform. The time for promises is past.

The great thing about my career in physics is that I never work, I just have a great time doing it.

At the same time, I've never been afraid of death or the concept of death.
