In this lecture  I will review some recent studies on the beneficial use of randomness in many real situations beyond physics.  In particular,  by adopting  random strategies, I will show how  it is possible to face successfully the problems of  the Peter principle in hierarchical organizations, to have a more efficient and democratic Parliament, to tame  the wild fluctuations  of  financial markets,  to counterbalance the unpredictable role of luck and  foster  innovation.
