Quotes:
• Applause is the most powerful thing… people talk about the sound of it, but what I hear is glee. — Carol Christine Hilaria Pounder (1952-) Guyanese-born American actress
• You gleefully say, “I just thought of something!”, when in fact your brain performed an enormous amount of work before your moment of genius struck. When an idea is served up from behind the scenes, your neural circuitry has been working on it for hours or days or years, consolidating information and trying out new combinations. But you take credit without further wonderment at the vast, hidden machinery behind the scenes. — David Eagleman (1971-) American neuroscientist
