we make our world significant by the courage of our questions and the depth of our answers

The cosmic calendar compresses the local history of the universe into a single year. If the universe began on January 1st it was not until May that the Milky Way formed. Other planetary systems may have appeared in June, July and August, but our Sun and Earth not until mid-September. Life arose soon after. We humans appear on the cosmic calendar so recently that our recorded history occupies only the last few seconds of the last minute of December 31st.

The universe is a pretty big place. If it's just us, seems like an awful waste of space.

The sky calls to us. If we do not destroy ourselves, we will one day venture to the stars.

A multitude of aspects of the natural world that were considered miraculous only a few generations ago are now thoroughly understood in terms of physics and chemistry.

We live in a society exquisitely dependent on science and technology and yet have cleverly arranged things so that almost no one understands science and technology.

The cure for a fallacious argument is a better argument, not the suppression of ideas.
