What determines the longitudinal stability of an airplane?
The location of the CG with respect to the center of lift.

The longitudinal axis of an airplane is an imaginary line running lengthwise from nose to tail. Movement around the longitudinal axis is referred to as "roll" and is controlled by the ailerons. Movement about the longitudinal axis results in a banked attitude of the aircraft (where one wing is higher than the other) and, combined with rudder input causes the aircraft to turn.

There are three axes of motion on an aircraft, they are the lateral, longitudinal, and vertical. The lateral axis is from wing tip to wing tip and it is responsible for pitch. The longitudinal axis is from nose to tail and it is responsible for roll. The vertical axis goes straight down from the top to bottom and it is responsible for yaw. The elevator controls pitch along the lateral axis, the rudders control yaw…
The largest determinant to an atom's behavior is its electron configuration. An atom's electron configuration determines its interactions with other atoms, such as which atoms it can form bonds with and whether that bond is covalent or ionic. Additionally, the number of neutrons and protons influence the stability of the atom's nucleus.
While there are many different scientific principles and disciplines used to design and build an airplane, I suppose the most important "science" would be that of aerodynamics. Aerodynamics is the science that determines the shape of the wings and the fuselage, and how it performs while moving through the air.
