"All science is either physics or stamp collecting." - Ernest Rutherford



Which physics relationship is more important?

How the binding energy per nucleon depends on atomic weight (makes possible fusion--that's what happens in the sun--and also fission).
How the gravitational force between two masses depends on their separation (shapes the universe).



Which unanswered question in physics is more important?

How can we explain the "Pioneer Anomaly?"
What happened at the Big Bang? (and before?)
