one song to the tune of another - explained
Try to think of the song as an ordinary everyday object - like a nuclear particle accelerator for example. This handy gadget is basically only two components, the linear cyclotron and the elemental betatron, and you hardly need to have what they do explained. As you know, these can be realigned in such a way that particle beams split supra-segmentally rather than by relativistic modulation. I know what you are thinking, surely that configuration creates a proton synchroniser? Exactly!
But there is another component we haven’t touched on - that’s right the plug. How many times have you tried to use your particle accelerator only to find you had forgotten to plug it in? That is why so many atomic research establishments take on someone whose sole job it is to perform that menial repetitive task requiring a minimum skill base and little or no training. Even then there are those that fail the interview and are forced into casual employment elsewhere. At the piano please welcome Colin Sell.
Now 1 + 2 = 3, and the numbers 1 2 3 (usually expressed in that order by experts) are the factors of 6, which is what is known as the first perfect number. The only thing known about a perfect number is that we have never yet heard one from Colin Sell.
