Man Is The Matter Of The Cosmos,

The Reappearance Of The Crescent Moon After The New Moon; The Return Of The Sun After A Total Eclipse, The Rising Of The Sun In The Morning After Its Troublesome Absence At Night Were Noted By People Around The World; These Phenomena Spoke To Our Ancestors Of The Possibility Of Surviving Death. Up There In The Skies Was Also A Metaphor Of Immortality.

Not Explaining Science Seems To Me Perverse. When You're In Love, You Want To Tell The World.

One Of The Reasons For Its Success Is That Science Has A Built-in, Error-correcting Machinery At Its Very Heart. Some May Consider This An Overbroad Characterization, But To Me Every Time We Exercise Self-criticism, Every Time We Test Our Ideas Against The Outside World, We Are Doing Science. When We Are Self-indulgent And Uncritical, When We Confuse Hopes And Facts, We Slide Into Pseudoscience And Superstition.

Extraordinary Observations Require Extraordinary Evidence To Make Them Believable.

If The Greenhouse Effect Is A Blanket In Which We Wrap Ourselves To Keep Warm, Nuclear Winter Kicks The Blanket Off.
