Science can amuse and fascinate us all, but it is engineering that changes the world.

I never considered myself a patriot. I like to think I recognize only humanity as my nation.

Part of the inhumanity of the computer is that, once it is competently programmed and working smoothly, it is completely honest.

You see, proteins, as I probably needn't tell you, are immensely complicated groupings of amino acids and certain other specialized compounds, arranged in intricate three-dimensional patterns that are as unstable as sunbeams on a cloudy day.
