Science began with mythology, when people started creating
ways to understand how the natural world works. Long before
they used written words, the Greeks conceived fictional science
—intelligent robots, for example, appear in the Iliad.

Today’s scientists are delighted to know that they rarely have final explanations, and there’s no end to new questions. Likewise good
science fiction writers, who are rich in the boundless fascinations that humans find in the adventures of other humans.
