The bit as the measuring unit of information is a human creation, just 
as the meter is for distance.  It is a human abstraction, to describe a 
physical attribute.  It is a "secondary" abstraction, made by humans, 
who themselves are built from "primary" abstractions called elementary 
particles.  Does not matter how hard do I look an elementary particle, 
or even a mountainy, I do not see just from the "outside" the 
intelligence that is capable to make this secondary abstraction.  Now a 
machine is a "tertiary" abstraction, and being so it is much more 
convoluted and complicated and  slower than a primary one, for example a 
simple molecule.  A computer, a machine does not have a connection to 
Information Ocean, like a human has, because it is not built from 
humans, but by humans.  So a machine is stuck at the secondary or 
tertiary abstraction level and till humans are not building that special 
parts - like a human brain -, for the machine to communicate to 
Information Ocean, the machine will never able to do more, just to build 
things starting with "n", - like numeric :-)  Telling otherwise the 
information in Information Ocean is not really that bit that we humans 
use to measure information content, just as distance is not really the 
same as the meter to measure it.  Probably we would run into similar 
difficulties with human perceivable information as we go down the scale 
as we had with distance as we approached the atomic scale.

little. "Planet" is the name of a simple (and rather shifty) story we 
tell about celestial objects. "Pluto" is the name of another story, but 
that's much more complex. The concrete reality behind the story is 
easier to find, and we can relate it to other stories (e.g. "methane"). 
Dualism is actually a barrier to real understanding here.

while logic is useful in elucidating the relationships between 
hypotheses, it cannot determine truth. Logic steps from falsehood to 
falsehood as easily as it steps from truth to truth.

mechanism remains elusive. I thus think Boole's belief has been 
comprehensibly falsified.

bits are fundamental to anything physical.

this message is full of dualism: while dualism isn't very true to how 
the world works, it seems essential to human communication. Can we, in 
mathematics and science education, learn to better exploit this 
mechanism while also teaching awareness of its profound difficulties?
