Gotcha. So whenever someone claims an absolute technological

("the sound barrier was like a brick wall in the sky"), one should
always append to that claim the phrase "...with current technology".

Like I said, didn't we go over this once before?

Why don't you read up on communications theory and figure out what is
going
on.

You mean, like everyone else read up on communications theory when they
claimed that we couldn't go past 2400bps.

Or when they read up on aerodynamics and claimed, definitively, that you
couldn't fly faster than the speed of sound.

We've heard it all before.

Are you willing to put money on any of this?


I am curious, how many courses in communications and information theory have
you taken?

Have a degree in any of the appropriate fields?
Any publications or patents? A hobby in mathematics?

What is your background to support your contention that information theory
is all wrong and you on the other hand are correct?

Your "history" of modems is false. You have ignored the simple fact that
commercial technology is driven by costs and availability of technology and
almost never truly by physical limits. Bell 2xx modems were NEVER up against
the channel capacity limits, they were up against the signal capacity of the
modulation technique that was currently affordable and the signal/noise
environment that was then the norm.

Your supersonic claim is laughable for as I said, bullets had been
supersonic and KNOWN to be supersonic for many decades prior to the X1's
flight. Ernst Mach worked with supersonic velocities in the 1800's. This was
not a secret.

These issues were simplified for the technically ignorant and you have
mistaken the simplified description for the state of knowledge - just as you
have for modems, just as you have for TV and I suspect for many other
topics.

Ignorant opinion stands in a weak position when compared to rigor.
