Sorry, Craig, you got this wrong.
Light of different colors is light of different frequencies.
The frequency of light emitted by some atom, does, in fact, 
exist independent of our brains. It's called hertz.

Using your argument, only the word "color" is dependent upon
out brains to interpret it (as you point out below).

Oh dear. In an attempt to give my view of an apparant stretching of a 
word's definition I seem to have done the same thing. :^)

: Here is some real flame bait [addressed primarily to Mr. 'Vibrating' ;-)]: 

Actually Vibrating is my first name. You may call me Vibrating but for

Well, I recently posted this in another newsgroup 
(rec.sport.rugby.league, strange as it may seem) which may answer the 
question:

In otherwords, just because we do not know of something or are unable to 
comprehend it does not mean such a thing does not exist. 

<Dogs doing calculus in their heads to catch balls snipped for brevity ;^) >

Now then, the defintion I attribute to mathematics I laid out like 
this:

What I'm trying to say here is that it could be argued (by me amongst 
others) that the relationships between objects and phenomena exist 
anyway. Mathematics is the ongoing creation of a extraordinarily rich and 
diverse language which enables us to express those relationships. A 
mathematician is creating a tool for scientists and engineers alike. It 
may require a mathematician to make use of that tool at times but, at 
it's very core, tool creation is what I believe to be the essence of maths.

I don't see it as being different from any other language in that it 
enables us to get a particular idea or point of view across. It often 
does so with more success than I do with English, but there I digress. :^)

Distant unknown planets do not crash into their sun because no one there 
has *discovered* the inverse square law. That relationship continues 
to exist in a form unexpressable to the local inhabitants. 

That is what I meant by saying "Mathematics exists in the mind alone". 
The relationships and properties are already there but the language 
used to describe them is a human creation.

: The universe does not revolve around the human race.  The human race is a

I do not, not by any stretch of the imagination. I'm quite sure that my 
comprehension of the universe we live in is inexplicably small in 
relation to the size of that universe. As such I'm quite happy to be 
talked out of a point of view if I can be convinced I'm on the wrong 
track.

Chris.

	I like to think of mathematics as a means of expressing the
relationships between numbers. The angles of a square, the lengths of
the sides of a pentagon, even the relationships between musical notes
can be expressed as a pattern of numbers. C4 is 12 notes from C5 is a
perfectly valid mathmatical statement. Programming is merely a way of
expressing the relationships between a computer and the outside world.

	One is a totally arbitrary name. It may be called "Throbene" for all it
matters, it is merely a way of expressing the number. The names for the
numbers are a human invention, the numbers themselves are not.

You are not helping the cause any. Color arises from how are brains
process light, and does not exist independently of our perceiving it.
Because of this, it is clearly only in our minds even more than math
is. I think Mr. Goats point can be made clearer once you realize that 
math is about symbols and how you can transform them into one another.
"2 + 2 = 4" seems to be expressing a relationship of some sort that 
exists externally in nature, but what it means and how we interpret 
is actually quite close to how we process langauge. You wouldn't say 
English exists in nature, and is not solely the product of our brains, 
just because you can point to a big leafy green thing and say "tree".
It is not like the word "tree" was laying about, just waiting to be
discovered, any more than the symbol "2" was. In this sense (and in
many others as well) math is a product of our brains.

Spoken like an engineer.  I don't think many scientists would actually
say this sort of thing.

Go read G.H.Hardy's _A Mathematician's Apology_.  Considering that (in
my experience anyway), the (vast) majority of mathematicians hold
basically the views expressed there, you will immediately see what a
"hornet's nest" you have just kicked.

So - how do you feel about the "Copenhagen interpretation" of QM?

Not broad enough. There exist plenty of abstract mathematical entities with
interesting formal properties that are nevertheless not numbers.

Try to see it that way:
Without minds to think, there would be no numbers. Of course there would
still be one earth, but the abstcraction from the planet to the number 1
would
not be made. But that abstraction is what mathematics is about.
Therefore: No mind, no mathematics.

That's wrong. Wavelength is wavelength, color is color. There is a relation
but it is not nearly as close as you seem to think. Color is definitely
about perception. You can perceive color even though no light of the
relevant wavelength is present. the Land two color experiments (and many
other similar experiments) show this conclusively.

That is false, Spiff.  Colors can be perceived as a result of a pure frequency
or as a result of the mixture of two or more frequencies. The eye only responds
to two or three different regions of the spectrum. This is why only three
different kinds of phosphor elements in a CRT display are able to reproduce
such a wide variety of hues.

>The frequency of light emitted by some atom, does, in fact, 
>exist independent of our brains. It's called hertz.

From this it does not follow that every brain perceives color in the same way,
or that color exists independently of the observer. I don't see the necessary
connection between frequency and the sensation of color.

I think a distinction should be made between NUMBERS and NUMERALS. Our
mathematical system's rules are not arbitrary, they have been chosen
because of their mapping to the laws of numbers we see in nature,
e.g. if we have 4 things (I mean the number 4, not the numeral) and
remove 2, we clearly have only 2 remaining. Admittedly, maths is not a
science per se because most of it deals with platonic ideas that
cannot be directly seen or touched, making it trickier to get a handle
on in these areas than e.g. physics, but I think it's wrong to suggest
that something like the Mandelbrot set doesn't exist outside people's
minds.....surely the Mandelbrot set is a discovery, not an invention?
I don't think mathematical systems can have the arbitrariness of
languages. The numerals and symbols can be arbitrary, but their
transformation rules MUST consistently map onto and track the
relationships of numbers. But getting your head around the
verifications involved in this is indeed tricky stuff......

OK, I finally got sucked into this maelstrom.

Why are people talking about numbers so much?  There seems to be a strong
impression that mathematics = the study of numbers.  No, that's 
arithmetic.

Mathematics is the study of logical implication: one puts up a set of
postulates and studies the theorems (implications) that result.

Some of these postulates concern these "number" things (like Peano's
postulates).  Others concern these "geometric" things (like several
people's attempts to perfect Euclid's postulates).  Others concern
things with no obvious relation to observable reality.  (The latter
are often the most interesting and turn out to have great impact on
the "real" world.  Talk about serendipity!)

When I was working on that elusive Ph.D. in math, my field was
topological algebra (as distinguished from algebraic topology).
I REALLY didn't deal with numeric concepts.

0 (Zero) ! A cow on a catapult does not move much. This changes when the

What if it hits the observer?

>Conclusion: The tree makes a sound when it falls.

When a tree falls in the woods and crushes a deaf-mute, is there a sound? 
And in the same vein, what must the initial velocity of a cow being flung
from a catapult be in order to achieve orbit?

Good point.  Here are a couple (not too good, complete or
elaborate) definitions:

1)  Molecular vibrations of a particular type.  (Typically in air.)
Implication:  Tree does make a sound.

2)  A human experience which all humans (who are
    not deaf) know about.

Implication:  Tree does not make a sound.

Schrodinger fastened a piece of toast to the cat's back and dropped it.
Since a cat must always land on its feet, and a piece of toast must
always land buttered side down, the only way to resolve the impasse
was for the cat (without the fiddle) to follow the cow to the moon.

With hopes of antigravity, Schrodinger tried to duplicate the
experiment, with another cat, but so far has been unable to get a cat
to hold still long enough.

But orbit is not good enough.  The cow should jump over the moon.

That doesn't have much of an impact on the tree, only the stupid
observer.  Of course, according to the Hiesenberg Uncertantity
Principal, the observer either alters the location of the tree or alters
the motion of the tree, depending on whether the observer is measuring
the speed of the tree or determining its location.

No. Sound is a cranial occurance.  The motion of the tree produces
compressions and refactions in the atmosphere, it requires and ear and a
certain minium congnitive ability to convert the compressions and
rarefactions into sound.  A deaf mute does not have the requisite ear. 
Of course, almost any animal could be present to make the needed
conversion.

The cow would not be able to acheive orbit, but you would have an
interesting phenomona, a meteorite rising from the Earth's surface.  Not
to mention, a very well done roast, somewhere.

Well, what is the required velocity (magnitude and direction), if said
launch should take place in central Iowa?

As somebody pointed out, let's use the velocity of the cow after it's
flung from a catapult, rather than the initial velocity (0, and remains
so until we fire the catapult).

It can't go into Earth orbit without a course correction, since if
it were in an orbit it would return to the last point delta-V
was nonzero, which corresponds to the catapult.  It will likely
have left due to Earth's rotation, but that's still deep in atmosphere.

So, we come up with the following questions:

What's the terminal velocity of an unladen cow?

Will the cow burn up in re-entry?  Or will there be parts only
medium well?

Is this an African or a European cow?

If it burns up on re-entry, wouldn't it also burn up on leaving the
catapult?

What does any of this have to do with comp.lang.c?
