Writing Is Perhaps The Greatest Of Human

Atoms Are Mainly Empty Space. Matter Is Composed Chiefly Of Nothing.

We Are The Only Species On The Planet, So Far As We Know, To Have Invented A Communal Memory Stored Neither In Our Genes Nor In Our Brains. The Warehouse Of This Memory Is Called The Library

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.

Ask Courageous Questions. Do Not Be Satisfied With Superficial Answers. Be Open To Wonder And At The Same Time Subject All Claims To Knowledge, Without Exception, To Intense Skeptical Scrutiny. Be Aware Of Human Fallibility. Cherish Your Species And Your Planet.
