Today, everyone is familiar with Neil Armstrong's famous words as he first set foot on the moon: "one small step for man; one giant leap for mankind."

This book guided Jennifer Doudna to focus her studies not on DNA, but on what seemed to take a backseat in biochemistry: figuring out the structure of RNA, a closely related molecule that enables the genetic instructions coded in DNA to express themselves.

Phaedrus lures Socrates outside the walls of Athens, where he seldom goes, by promising to share a new work by his friend and mentor, Lysias, a famous writer of speeches.
