\"It would be better for the true physics if there were no mathematicians on earth.\" - Daniel Bernoulli (February 8, 1700 - March 17, 1782)

This paper claims that physics textbooks, the internet, science museums and even NASA incorrectly explain the phenomenon of lift by misapplying Bernoulli\'s Principle. Thus they are, ironically, validating Bernoulli\'s quarter century old proclamation about mathematicians. This paper also proposes a replacement theory to explain lift: namely, Radial Momentum.

The misapplication of Bernoulli\'s Principle rests on the incorrect assumption that lift occurs with incompressible (constant density) fluid. This paper claims this assumption is incorrect and that, indeed, the decrease in density that attends radially expanding fluid is essential to the explanation for lift.
