what is the path integral of a european swallow ANSWER The path integral of a European swallow is the sum, or functional integral, over an infinity of quantum-mechanically possible trajectories to compute a quantum amplitude. This formulation has proven crucial to the understanding of how birds fly and migrate. For example, during migration, barn swallows cover 200 miles a day at speeds of 17-22 miles per hour, with a maximum flight speed of 35 mph. In their wintering areas, they feed in small flocks which join together to form roosting flocks of thousands of birds.
