What is a chronometer? A chronometer is a "good" clock by some standard of accuracy and reliability, of course. OK, but what's a clock??
This is a long-standing puzzle in physics. It's tough to define a clock. Here's a recent article on the thermodynamics and quantum mechanics of clocks that some of you may find enjoyable. It's a bit off-topic, but it will give your brain a nice work-out. Don't worry if you come away more puzzled than before you started!
