Certain things, certain events, seem inexplicable only for a time: up to the moment when the veil is torn aside.

Unless a thing can be defined by measurement, it has no place in a theory. And since an accurate value of the momentum of a localized particle cannot be defined by measurement it therefore has no place in the theory.

Beauty begins the moment you decide to be yourself.

If you neglect to recharge a battery, it dies. And if you run full speed ahead without stopping for water, you lose momentum to finish the race.
