I have the qualification of being able to read. From the top of the sampling theory whitepaper: "Nyquist Sampling Theory: A sampled waveforms contains ALL the information without any distortions, when the sampling rate exceeds twice the highest frequency contained by the sampled waveform." This is simply incorrect, as mentioned by a couple other posts. I'm not going to argue that most of a signal can be reproduced with a reasonable number of samples, but saying that all of it is reproduced (which is repeated, again in caps, later on the same page) is misleading.
The Nyquist theorem assumes infinite accuracy as well. And it's a mathematical theorem, with thorough mathematical proof behind it.
In the real world it would be impossible, of course.
Disputing the Nyquist theorem as being false, which is a theorem fundamental to signal processing, is like saying Pythagoras' theorem can't be true because you can't have 100% right angles in the real world.
