text: xprts only plz: can we see any other way than digital? can we see things that aren't digital?   >>>can we see any other way than digital?  the only way we can see is analogue. human vision is totally anlogue. it is not digital.  >>> can we see things that aren't digital?  yes, everyhting we see is analogue.    the only way you could possibly stretch a description of human vision to say that it is digital is to invoke the fact that the neurons work on an all-or-none system. the inidvidual neurons are effectively digital.  however a single neuron will not produce vison, or any reponse at all, in the brain. vison is only possible by the intersction of thousands of such neurons, and that interaction is entirley analogue.  humans do not and can not see in a digital manner. our eyes and brain are both analogue machines.
