Hello, Recently I've learnt about Fourier Transform, and the uncertainty principle that is arose from it. According to Fourier Transform, if there is only one pulse in a signal, then it is composed from a lot more frequencies, compared to the number of frequencies that are building a repeating pulses in a signal. But I'd like to talk about a logical paradox- if we belive that the Fourier components, the harmonic waves, are building our signals in nature, and the particles, and etc, so let's look on a repeating pulse in a signal - when we operate the first pulse, it is composed from many frequencies, and when we operate the second and the following pulses of the signals, then all the pulses including the first one in the signal are composed from less frequencies. Can the second pulse change the number of frequencies that built the first pulse?! Also, when we make a noise in certain dt [sec] it is composed of more frequencies, then if we continue the pulse to: 2dt[sec]. Where the many frequencies gone to? Could the first part of the pulse know that we will continue the pulse later, so it will effect it to use less frequencies to build it? This paradox, can be explained, as I understand it, by observing the Fourier Transform as only a mathematical algorithm that helps as to analyze the signal, only after we know the whole shape of it. Namely, only after we see how many pulses are in it, and how long it is. And for the famous uncertainty principle that says: dt x dw ~1. It is only the limitation of this Fourier algorithm, but is not a limitation of nature. This uncertainty principle is more an uncertainty limitation when we try to analyze the nature in harmonic functions as building blocks. But if we won't assume nature is built on sin, and cos waves, so we won't suffer from this uncertainty principle everywhere. Only when we try to measure things with our instruments ,and analyze it with Fourier algorithm, then we will have the uncertainty limitation of our measurements. Because I'm only starting to learn with physics, so maybe those things are wrong or already known, so I'd like to hear your opinion on this matter. Yael Perkal, Israel.
