Absolutely. Real physics includes real noise, real turbulence, real surface roughness. A PDF can teach you the equations, but a wind tunnel teaches you that theory and reality are always in negotiation. The best aerodynamicists use CFD to hypothesize and tunnels to verify.

Lift is the glory of aerodynamics; drag is the price. And here again, real physics argues against the simple division into “parasitic” and “induced.” At the most fundamental level, drag is the irreversible transfer of kinetic energy from the body to the fluid. Two mechanisms dominate: Absolutely
Doug McLean's "Understanding Aerodynamics: Arguing from the Real Physics" bridges the gap between theoretical formulas and physical reality, focusing on cause-and-effect relationships and "Mental Fluid Dynamics". The text corrects common misconceptions, covering foundational physics, boundary layers, and lift mechanisms based on practical engineering experience.
