many things are out of our control and we cannot control them, do you think it is simple?
No...I don't think that is simple
We have different definition on simple
I can't write it out explicit/clearly...
for example.
Newton 2nd law
F = ma and it governs a lot of motion
Equation is neat, simple and pretty to me
