What is the difference between Helmholtz and Bernard in Brave New World?

In "Brave New World," Helmholtz is an Alpha Plus who struggles with conforming to the rigid social structure and feels unfulfilled creatively. Bernard, on the other hand, is an Alpha who is physically and socially maladjusted, feeling alienated and inadequate within the society. Both characters represent different forms of discontent with the World State's conditioning, but express it in distinct ways.
