For a fixed mass of gas, at constant pressure, the volume is directly proportional to the absolute temperature. V1 / T1 = V2 / T2 such that as T increases, V increases.  In other words, the harder you try (T) to keep a baby or toddler quiet, the louder (V) they get.

When a body is partially or completely immersed in a fluid, it experiences an apparent loss in weight that is equal to the weight of the fluid displaced by the immersed part of the body.  

The concept of micelles was introduced to describe the core-corona aggregates of small surfactant molecules (i.e. the flock of adoration that surrounds a new Dad with a baby in a carrier).

Buffers are solutions that resist a change in pH (i.e. sanity) on dilution or addition of small amounts of acid (babies) or alkali (toddlers).

4.5 billion years ago, Theia collided with Baby Earth and together, they form a  new Earth and moon.

A parcel of air (i.e. dirty diaper smell) expands and become less dense as it rises.  This occurs because the air pressure lowers around a parcel (i.e. dirty diaper smell) as it increases in altitude.  The volume of the parcel (i.e. dirty diaper smell) increases since it is expanding.  The mass of the parcel (i.e. dirty diaper smell) remains constant since adiabatic theory assumes no exchange in mass between parcel (i.e. dirty diaper smell) and environment.

A solid body in which deformation is zero or so small it can be neglected.  The distance between any two given points on a rigid body remains constant in time regardless of external forces exerted on it (e.g. an unwilling toddler in a car seat).

The motion pee takes when an unsuspecting caregiver removes a diaper.  The object or pee moves in a plane with constant acceleration along a curved path under the action of gravity only.
