Also this, (funny, but very true): In the army they teach you to march, and each soldiers must walk in the same rithme. Everybody knows that. But, they also teach there that if you need to cross a bridge while marching, the soldiers may not march in the same rithme! But each soldiers must march slithly earlier/later then the one before him. This is because of the same thing, the marching frequency of a whole platoon marching in the same rithme could demolishe a bridge!
oh, yes! that's also true. At the end, it's all due to the same phisical effect. the resonance frequency.
