- Who is Godot? What does he Mean? Is he supposed to be God? The magic words: Who Cares? Godot is what Alfred Hitchcock called the MacGuffin – a plot device about which the characters care desperately, but the audience isn’t meant to give a damn.
- Riemann hypothesis (Wikipedia)
In mathematics, the Riemann hypothesis is the conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part 1/2. Many consider it to be the most important unsolved problem in pure mathematics. It is of great interest in number theory because it implies results about the distribution of prime numbers. It was proposed by Bernhard Riemann (1859), after whom it is named.
