Is there anything useful I can do given those conditions?

	I don't know what the added cost of printing red/blue
stereograms might be, but it is probably something like the price of a
colour page even though only two colours are needed.  I have always
found that red/blue stereograms degrade the images significantly.  It
works pretty well for drawing, diagrammes and comic books, but gets
irritating when a photograph has any degree of subtle shading, as
against high contrast.  I have seen photos presented in red/blue, but
have never tried to make one.

	One hint about their suitability is how quickly red/blue was
abandoned when the polaroid became available, both for slide projection
and for movies.  In my experience the best display is through a good
viewer made of optically correct glass, second is a plastic viewer,
third is free-viewing, next is polaroid projection and the last choice
is red/blue pairs.

	I'm glad you had no trouble with the pairs in _JW_.  They are
nearly the perfect size for people who don't have much experience with
free-viewing.  With a bit of practice you can also view pics about
double those printed there.  Anything much bigger than that requires you
to switch them for cross-eyed viewing.  Salvadore Dali even did a large
painting intended for cross-eyed viewing and Rene' Magritte also did
some stereo paintings in the same format.

	What we need now is an artist/juggler to design a stereo T-shirt
so that we could force people to cross their eyes whenever we walk
toward them. ...  Maybe Martin Frost could also concoct some two-hand
passing patterns for crossed eyes, kind of a Mills Mess for the
eyeballs.

	An now, back to reality.

Organization: Carnegie Mellon University
Date: Thu, 21 Jan 1993 14:56:29 GMT

Many of those roboticists do juggle.  But the theoretical computer scientists
seem to be better jugglers.  I wonder why?  

Mohit asked, does one's own juggling transfer to one's robot?  Not clear.  But
studying biological systems can sometimes help guide design of robotic systems. 
In particular, Sakaguchi, Masutani, and Miyazaki (IROS 91) recorded data of two
guys, each doing two-ball fountain.  For each subject, the hand followed a
roughly elliptical path.  But the locations of the release and catch points along
the ellipse seemed to differ between the two subjects.  Sakaguchi et al designed
their robot to use elliptical paths too.

I've been juggling more intensely recently, partly in hopes of transferring
the skill to a robot.  It is too soon to tell whether I'm getting any
useful insights.  There are a couple of things that I could use some help on.

First, analysis and design of a catch would be a lot simpler if there were only
one strike, rather than a sequence of bounces.  One way to do that would be to
have a zero coefficient of restitution---a perfectly plastic impact.  Like when a
beanbag hits a concrete floor.  I've noticed that when I drop a lacrosse ball
into my hand, it doesn't bounce.  But if I repeat the experiment with my hand
resting on a table, the ball bounces.  Apparently flexion of the elbow joint
gives an effective restitution of zero.  But it only works with heavy enough
balls.  Nerf balls of the same size don't work.  It makes me wonder if very light
balls would make blindfold juggling impossible, or harder.

To apply the same trick to clubs, you need to cancel the translational and
rotational energy simultaneously.  In theory, this can be done by striking the
club at the center of percussion.  I notice that if I catch a club in my usual
fashion, but don't close the fingers, the club really does seem to strike without
bouncing, hang motionless for an instant, then slip off.  This suggests that
velocity-matching and closing of fingers play only a secondary role in catching. 
Any reaction?  It also suggests that clubs could be tuned "scientifically", by
matching mass and angular inertia to the dynamic characteristics of the human
arm.  Maybe even customized to the individual juggler, since some of us are
beefier than others.  Much as the "tuned track" was designed to match human
running dynamics.

The details of release are also interesting.  Baseball pitchers let the ball roll
off the end of the fingers to get speed and backspin, and they use knucklers to
get slow rotation.  But in juggling things are different because the speeds are
too low for aerodynamic effects.  (Aren't they?)  We care mostly about accuracy. 
How do the details of release affect accuracy?  Does it help to let the ball roll
out of the hand?  Do good jugglers all give similar rotation to the ball?

"In 1985, he made an unexpected appearance at the International Information

rooms that the snowy-haired man with the shy grin who was wandering in and
out of the sessions was none other than Claude Shannon.  Some of those at
the conference had not even known he was still alive.

"At the banquet, the meeting's organizers somehow persuaded Shannon to
address the audience.  He spoke for a few minutes and then--fearing that he
was boring his audience, he recalled later--pulled three balls out of his
pockets and began juggling.  The audience cheered and lined up for
autographs.  Said Robert J. McEliece, a professor of electrical engineering
at the California Institute of Technology and chairman of the symposium:

I hear that Claude Shannon also has a tilted air-hockey table on which to 
juggle in effectively lower gravity. (Which seems a great way to learn, 
to me: in particular, it forces you to throw from the middle, rather than 
throwing and catching in the same motion.) 

I think Buhler (who worked with Koditschek) is Joe Buhler, of the siteswap
mathematical paper, and has taught many famous mathematicians to juggle
(such as John Horton Conway of Life fame).

I got the impression from talking to Koditschek that he had very weird
ideas about juggling (i.e. that an experienced juggler wouldn't have). 
I don't remember precisely what, now; one thing I do remember is that 
in the robotics applications they were after, it was much less important 
to be able to juggle many, than to be able to recover from really grievous 
error. And indeed, their machine could fix situations no human could.

 Anyone got any suggestions for things to do in lifts that actually make
use of the varying gravity? I've been just plain juggling (which, oddly
enough, is easier at the bottom end, when gravity increases -- the
ceiling in lifts is so low that to fit five balls under it without
bending my knees, I need all the help I can get -- at the top, they just
tend to hit the ceiling that much more often.), and trying chin balance
(easier at the top, as things slow down under less gravity).

 Still working on keeping five balls going all the way down/up -- managed
both transitions at each end, but not on a single trip; that said, the
ceiling is only about 6'4, which really speeds things up a fair bit.

I know its not for a while but I thought I should let people know how
its going.
OK.

When and Where

    1-5th September 1993 in Leeds, the North of England, Europe

Facilities

    So far the convention will take place on two different sites. The
sports halls will be at the Metropolitan University (where the
British one was a few years ago) and most of the accomodation is at
University Halls of residence 20 mins walk away. There will be a
shuttle bus between the two sites. The price for rooms is about stlg12
sterling a night. At the Universty that includes breakfast, at the
Metropolitan that does not. Camping is of course free and there will
be places to park up buses.

Cost and Registration.

    The convention will cost stlg25 sterling for all 5 days. There will
be tickets for less days available at cheeper prices. I don't have
the address for registration at the moment but if you want it the
email me.

Other Attractions.

___THE PEKING OPERA____

    Its looking very likely that 15 members of the Peking Opera will
be coming across to preform in the public show and GIVE WORKSHOPS.
    If anyone hasn't come across the Peking Opera, its got very
little to do with singing and lots to do with circus (acrobatics,
clowning, staff twirling, sword, hammers,.....) Not to be missed.

    Unfortunately we were unable to get a major European circus, the
council weren't able to underwrite them and so it was too big a risk.

    Were also trying to get Antony Gatto to come along and Karl
Heinze Zeithan (I dont think I've spelt that right but never mind)
but nothing is confirmed yet.

    There will be 2 or 3 public shows, everyone who comes gets a free
ticket to one of those and there will be the Renegade show on a
couple of nights aswell.

    I think I've rambled enough. If you're not convinced yet then I
don'k know what to do.
    If you have specific questions about the convention or feel like
offering your services for a specific thing, then get in touch.

   There is a reason that whenever Mike does this with another juggler, 
   the other guy always drops first, apart from the fact that he has
   actually practised this stupid trick. Mike keeps his margarine cold, and
   serves the other guy margarine at room temperature.

I was the volunteer in one of his shows in Mill Valley, CA.  Instead of
liver, we juggled whole chicken fryers (heavy and awkward to catch).  After
a long run (15 or 20 seconds), I finally dropped the chicken, but not the
2-pound margarine ball.  Of course, perhaps if my margarine had been cold,
I would've had more time to concentrate on the chicken.

 Aak! Personally, (and I'm not the only person I know who feels this -- not by
a /long/ way), The Complete Juggler is, whilst fairly encyclopaedic, well-nigh
useless to learn things from. For one thing, he's horribly brief with his 
descriptions of tricks -- he'll just say what a trick is, rather than how it's
done -- and, some of his instructions are downright counterproductive. The 
'how to learn five balls' method looks designed to teach you how /not/ to
juggle five -- learning how to stop rather than continue is going to teach
how to, well, stop. Not juggle. Hmph.

 And his use of traced photographs, whilst it may be accurate, is nothing like
as clear as well-designed diagrams can be. 

 Other books? Kit Summers' Juggling With Finesse is very good, and equally
all-encompassing (well, there's no huge section in the back about how to 
teach children, but that's no great loss IMHO); the Dick Franco books are
nicely made, if too heavy on archival photography -- and, of course,
Beyond The Cascade.
