Science is a collaborative enterprise, spanning the generations. When it permits us to see the far side of some new horizon, we remember those who prepared the way - seeing for them also.

Not explaining science seems to me perverse. When you're in love, you want to tell the world.

I believe our future depends powerfully on how well we understand this cosmos in which we float, like a mote of dust in the morning sky.
