Whose scientific principle explains the lift in an airplane wing?

Answer Daniel Bernoulli

Bernoulli's principle is basically conservation of energy for a fluid. As applied to lift, it describes how a fluid (such as air) moving at a higher speed will have lower pressure than slower moving fluid. Airplane wings are designed to have air move faster over the top and slower underneath. As a result they have higher pressure underneath the wing and lower pressure on top. This pressure difference produces the upward lift force.
