It took a world-champion instructor (Kainoa McGee) and ninety minutes but I started surfing at 61.

Conservation follows mathematically from isotropy, or continuous directional symmetry of space, that is, no direction in space is any different from any other direction. See Noether's theorem

A rotational analog of Newton's Third Law of Motion might be written, "In a closed system, no torque can be exerted on any matter without the exertion on some other matter of an equal and opposite torque." Hence, angular momentum can be exchanged between objects in a closed system, but total angular momentum before and after an exchange remains constant (is conserved)

Similarly, a rotational analogy of Newton's Second law of Motion might be, "A change in angular momentum is proportional to the applied torque and occurs about the same axis as that torque." Since a torque applied over time is equivalent to a change in angular momentum, then if torque is zero, angular momentum is constant. As above, a system with constant angular momentum is a closed system. Therefore, requiring the system to be closed is equivalent to requiring that no external influence, in the form of a torque, acts upon it

A rotational analog of Newton's First Law of Motion might be written, "A body continues in a state of rest or of uniform rotation unless compelled by a torque to change its state." Thus with no external influence to act upon it, the original angular momentum of the system is conserved

Funny but not too far from the truth...

What do you guys think?

People, when after a long long time return to us with open arms like nothing happened!! It seems like the burnt potato we threw back long ago has come back for recycling :-/
