What do you mean by 'effective'? if 'effective' means 'does well what it is supposed to do', then nuclear weapons are very very very effective. If 'effective' means 'helpful for humans', then either man-made fire or the wheel are the most effective ('man-made fire' specifically, because fire does exist in the wild, so 'fire' on its own is more a discovery than an invention).
