\Delta x\,\Delta p \geq \frac{\hbar}{2}

Limit on knowing position and momentum together.

ABV = (OG - FG) \times 131.25

Estimated alcohol content of beer or wine from gravity readings.

L = \tfrac{1}{2}\rho v^2 S C_L

Aerodynamic lift produced by a wing depends on air density, speed squared, area and lift coefficient.

C_{D,i} = \dfrac{C_L^2}{\pi e AR}

Drag due to lift, decreasing with higher aspect ratio and span efficiency.

AR = \dfrac{b^2}{S}

Ratio of wingspan squared to wing area; higher AR reduces induced drag.

WL = \frac{W}{S}

Aircraft weight per unit wing area.
