Signals from radio sources statistically look like noise". this is because we receive the signals from many, many electrons that are emitting sine waves of arbitrary amplitudes, frequencies, and phases. 1. explain in your own words why we receive the signal from many electrons (rather than just a single electron, or a few electrons) and why they all emit signals of different amplitudes, phases and frequencies. 2. what does "statistically looks like noise" mean? what properties of noise does this signal have? 3. demonstrate (in python) that such a signal will have noise-like properties
