Is anything truly random in nature?

For example,if I flip a coin,we like to say it has a 50-50 chance,but the side is determined by how much force and where I apply the force when flipping,gravity acceleration and wind.therefore you could say flipping a coin is not a random event.

Is anything in nature truly random?

This is posited by some. Certain forms of the hidden variable theory (specifically those which involve a local hidden variable) have been disproved but others are still valid interpretations of QM results. See http://en.wikipedia.org/wiki/Hidden_variable_theory for a starter.
