Ball Lightning

by Liu Cixin

“Actually, son, it’s not hard to live a wonderful life. Listen to me. Choose a tough, world-class problem, one that requires only a sheet of paper and a pencil, like Goldbach’s Conjecture or Fermat’s Last Theorem, or a question in pure natural philosophy that doesn’t need pencil and paper at all, like the origin of the universe, and then throw yourself entirely into research. Think only of planting, not reaping, and as you concentrate, an entire lifetime will pass before you know it. That’s what people mean by settling down. Or do the opposite, and make earning money your only goal. Spend all of your time thinking about how to make money, not about what you’ll do with it when you make it, until you’re on your deathbed clutching a pile of gold coins like Monsieur Grandet, saying: ‘It warms me…’ The key to a wonderful life is a fascination with something.

“That’s what scientific research is. Every step you’ve taken, no matter how absurd, is a necessary one.”
