What gives time a direction is (IMO) thermodynamics.  One of the consequences
of thermodynamics, according to Hawking in 'A Brief History of Time'
is that you can't remember the future.  (Not really too surprising :-)).
I don't recall the details, but basically a 'memory' device (like a
flip-flop, for instance) according to good ole thermo _can_ remember the
past, but not the future. Hawking argues that this is what gives time its
directional quality, and I tend to agree.

I also think the percieved 'velocity' of time depends on past experience -
this is a subjective thing, but as one gets older, time seems to fly by
faster (IMO).  I think this is because any given amount of time is shorter
compared to one's lifespan.  Then there are mood elements to the subjective
passage of time - when you're bored, it can seem like an infinity, but good
times often seem to go by too quickly.

     No one is claiming that theory is bad.  However, a computer
calculation is just that: a calculation.  If mathematicians use the word
"experiment" to describe some of their computer work, that's fine.
However, physical scientists must reserve to the word the exclusive
meaning of performing measurements on actual systems.
     Let's take a ridiculous example.  Suppose I want to know something
about ideal gases and calculate the pressure at several different
volumes and temperatures from the equation P = nRT/V.  Is that an
experiment?  Of course not.  Tell me now, just how complicated does a
calculation have to be before it becomes an experiment?  You see the
problem now, I hope.

You know, all this Larsonian physics stuff reminds me of
the episode about a year ago with Petr Beckmann.  To summarize,
he didn't really understand SR (let alone GR) so he re-wrote it.
Not suprisingly, he was flamed until he quit the net.  Mr.
McElwane (I'm not sure about the spelling, so I apologize if it's
wrong) seems to be promoting ideas that stem from similar misunder-
standings, but seems either even less inclined or incapable of
discussing them in a rational fashion then Dr. Beckmann was.

I have always had a mild interest in the bizarre gedanken experiment.
For example, what information do we have about matter that is outside 
of a gravity well?  What do we know about the fundamantal constants
outside of the earth's and sun's G field?  But questions like this are 
simply a way of learning more about the universe, and getting some
intelligent discourse going.

There is clearly a place for highly speculative physics on the net.
Unfortunately for Mr. McElwane, that place is alt.sci.physics.new-
theories.

I'll tread on the dangerous ground of quoting things I don't understand here.
If baryon number is a discrete gauge symmetry of a TOE then apparently baryon
hair can be expected in black holes, otherwise not. Either case, we'll likely
have to wait a fair while to find out.

This makes sense. What I don't understand is why a region of high density
homogeneity does not recollapse in a time appropriate to that density. I.e.
if the universe were filled with stars, in the density of a galaxy, the
universe would have recollapsed long ago. The region of space which is
inside a galaxy satisfies the same local einstein equation as the above
recollapsing example, so why do galaxies live so long?

Hello,

I'm looking for a few images to use for some experiments with a new
image segmentation approach.  Currently I'd like to find a few
remote sensing images with intensities at two or three wavelengths.
I've already found gif files of boston, new york and so on (for
example from vab02.larc.nasa.gov), but they aren't quite what I'm looking
for.  What I'd really like are a few simpler images where there are
larger, roughly homogeneous regions such as "corn," "soybeans," "water,"
"roadway," and so on.  The images I've found so far have easily
discernable "water" regions but the rest is much harder.  Best of
all for me would be images that are accompanied by a "correct"
segmentation, i.e. a standard to measure my results against.

I realize that it isn't too likely that what I'm looking for is
publically available, but I'd appreciate any help that could be
provided.

Hi,   
        I am trying to develop an image registration tool which can be
used to register remotely sensed images ( ie. geometrically align two images
of a common scene, taken from two different views and scales, so they may be
directly compared ).
 
        The registration process will be semi-automatic, using a set of
user-defined control points, to "map" one image onto the other. The software
will be compatible with the Khoros environment and will be implemented in C
on a SUN sparcstation.
 
        I would be extremely grateful to anybody out there who can suggest
any references, sources, papers, etc. on image registration algorithms.
So far I have only obtained information on bilinear transformations but I
like would to increase my understanding on how various Fourier Transforms may
be used in the registration process.
 
        I am a novice to image processing, ANY information relating  to
this subject would be greatly appreciated.
 
Thanks in advance for all replies.
 
James.

I have inherited some pages copied out of a book.  Unfortunately,
there is no indication on the pages as to the book they came from, and
it's one that I'm not familiar with.

The pages (I don't have all of them) appear to form an un-numbered
chapter entitled `Image Operation Studies'.  The first page is #129,
the last #172.  The next `chapter' is `Further Reading and
References', so I guess it's a fairly thin book.  There are 19
examples in the chapter; they're all pretty simple, implying that it's
an introductory text, but are nicely explained.

I would guess the book was published in the period 1983--1986.  Can
anyone supply me with a reference for the book?

Many thanks in advance.

The Wang Integrated Imaging System (recently ranked as the number one

equivalent or better functionality, and named OPEN/image for AIX.
Customer shipments began in September.

While "many vendors have been mimicking WIIS...., Wang has stayed ahead
by adding color and gray-scale support.  Wang is the only major
document imaging vendor to have achieved this," said Rich Barrett, manager
of the client/server component of the product.   The development group
also significantly improved the speed of black and white images.

Full information and demonstrations are now available from any
