Real cause: global flow field and pressure distribution

Incorrect belief that induced drag is caused by wake vorticity

Issues: Focusing only on surface interactions, neglecting broader flow impacts

Issues: Incorrect assumptions and lack of direct physical reasons

Open floor for questions and discussion

Brief mention of topics not covered due to time constraints

Reference to the speaker's book for detailed explanations

Importance of correct understanding in fluid dynamics and aerodynamics

Pressure reactions on the ground

Larry Wigton's contributions: No net downward momentum in the atmosphere

Misunderstandings about momentum in the atmosphere

Classical approaches vs. recent insights

Example: Drag due to lift in 3D

Misconceptions about vorticity causing remote velocity changes

Biot-Savart law: mathematical tool, not physical cause

Need for a comprehensive explanation combining Bernoulli and Newton approaches

Downward turning explanations: Airfoil shape and angle of attack

Bernoulli-based explanations: longer path length and stream tube pinching

Popular but insufficient explanations of lift

True explanations require understanding the dynamics (forces and accelerations)

Newton's third law concerns forces, not motion

Examples from Smithsonian and NASA websites

Incorrect applications in explaining propulsion and lift

Interaction of fluid with solid surfaces: no slip and no jump in temperature conditions

Explanation of forces: surface forces (pressure and viscous shear stress) and neglecting body forces (e.g., gravity)

Key concepts: velocity as a continuous vector field, kinematic rules, and Navier-Stokes equations

Fluid flows as if it were a continuous material

Focus on continuum fluid mechanics

Potential coverage of boundary layer separation in 3D and pressure drag

Impact of lift on atmospheric motion

Exploration of vorticity and the Biot-Savart law

Examination of misconceptions about lift

Discussion on Newton's third law and its common misinterpretations
