Exploding Meteors
When meteors enter the atmosphere, they are typically traveling at around 15km/s. At such
speeds, heat does not have time to be conducted away and even the air has no time to be

Perpendicular Axis Theorem
For a three dimensional object, the moments of inertia about 3 mutually
perpendicular axes are related due to geometry and the definition of the moment
of inertia.
