摘要: Since the dawn of time, human kind have felt presence shock waves in nature through thunders and vulcano eruptions and, unable to understand them, associated their often destructive might divinities such as Zeus Jupiter Greek Roman mythology, Norse divinity Thor, elusive Thunderbird Native North American culture. Through history, albeit unknowingly, humans been able generate via cracking a whip or explosion fireworks. It was invention atomic bomb that brought back fear respect towards this natural phenomena [1].
