Mad Scientist Questions

What's the happiest animal? When did people first stand in line? What plants are like mayflies, with very short lives? What could we put in a time capsule for our descendants a thousand generations away? Could a tree blowing in the wind be reshaped to sound more musical? How much gold dust is in the air? What's the noisiest size of gravel to walk on? When are mass extinctions good?
This book collects hundreds of eccentric questions to ponder, in topics ranging from steampunk machinery to animal behavior to ghost stories. The catch? There are no answers here. There may be no answers at all. The reward? No answers means that there are no wrong answers, so all speculation and discussion is fair game.
