You are failing to understand, which isn't rare when presented with information from someone that's been hanging around with a Timelord. It is nigh impossible to find the specific wave length of energy that I made use of, that even The Master's own Laser Screwdriver (which I believe is sitting in a vault in the TARDIS) would have difficulty. That being said, your instant use of the precise calculation to unlock the use of the speakers, and my microwave, defies both the laws of Newtonian Physics and the laws set by the scientific minds of Gallifrey.
