h, p, d or g
combine of these any three,
FEM in a periodic table,
Conforming, commuting and mighty stable.
If the numbers don't converge
the method hears a sombre dirge
If instead they go too well
the method may be quite spectr-el.
The Circus at the IMA
adaptive work, refined play;
from those (and not!) at the meeting
to Doug, a special birthday greeting.

Every Point at Avery,
Is much above the Average.
I heard some people say:
"Could we switch with Dmitriy?"
Said the newborn Mariner,
To the happy, plenty crowd:
"Alas, I like my Elements,
Water, Wind and Rain and Clouds."
On a pleasant inland coast,
Even with less sun,
This Circus has been fun,
Warmed by our host.

While joint meetings of the Finite Element Circus/Rodeo were held at the University of Texas in Spring 2000
and at Louisiana State in Spring 2008, this meeting a the University of Chicago Center in Paris, June 3-4, 2011,
must count as a Fabulous First: The FE Fair, the Rodeo, and the Circus combined.
It was organized by Christine Bernardi (Paris), Vivette Girault (Texas A&M) and Ridgway Scott (Chicago).
About 35 people attended, and while we do not have a complete record, to the best of our investigations,
the Circus showed the flag with seven members: Andrew Barker (Louisiana State), Alan Demlow (Kentucky),
Todd Dupont (Chicago), Rick Falk (Rutgers), Peter Monk (Delaware), Victor Nistor (Penn State) and Ridg Scott (Chicago).
No recorded poem for this occasion has been found, so instead the special menu at the Le Train Bleu restaurant is given:
Foie gras de canard compote'e d'oignons rouges
Souris d'agneau confite jus au thym/Gratin dauphinois
Brie de Meaux
Mi cuit tout chocolat, chantilly cacao
Cafe', Pays d'Oc viognier, Me'doc chateau Plagnac.

The Circus came from far away
to party at the IMA;
All these people highly keen
to honour Falk, Pasciak and Wahlbin
The messages were loud and clear
for PDE we all hold dear
Even though the slides flew by
speedier than asking 'why'?
`Hybridize your DG so
the error and the work be low!'
`Exterior calculus shall save us all
Use a complex, big or small!'
`Keep your talks not too long!'
Constraints from organizers, fairly strong
[This panick'd scribe they brow-beat
to craft this verse, (a minor feat).]
No matter what our FEM may be
h-conforming or h-p
we all do (in faulty meter)
thank Johnny, Jay, and Peter.
The message from the assembled `crew'
(and yes, there were some sailors few)
Dear Rick, Lars and Joe
Happy birthday, and many more!

In the fair town of Providence,
At a University named Brown,
There is plenty much of evidence,
They will never win the Ivy basketball crown.
On the other hand, on the evidence,
The Brown Circus wins, hands down,
One can say with much confidence,
That glorious DG crown of renown.

Stand in one little spot,
Shake your bending moments hot,
That's when you got something,
Yeah, you got a lot.
It is elements a-shaking,
Shaking hot as they can be,
Yeah, some elements a-baking,
Down in Knoxville Tennessee.

This Circus in Delaware,
May have made you aware,
To use care and avoid the snare,
To fall for deficiences bare,
Beware, be fair, and then dare!

To model gradients extreme,
With confidence most supreme,
Study element methodology.
Compare with the topology,
Of Troy; and then dream or scream.

A Circus and a Rodeo bring,
Elements that glow like bling,
Add a roaming tiger, too,
And you will have a Zoo,
Lots of horseplay in the ring.

The talks were flying by
At the Circus at Cornell.
Where one stopped and the next one started
Was almost impossible to tell.
In my mind, the talks have merged to one.
And I am sure you will agree
After hearing just the title.
It's the best in history.
L-infinity estimates and fast solvers
For methods nonconforming, mesh free, or DG
For the Darcy-Stokes-Monge-Ampere equation
With a corner singularity.

There was a young man named Galerkin,
In numerical methods researchin'.
On even days smooth and continuous.
On odd days rough, discontinuous.
A divide in Galerkin was lurkin'.

Thirty-six talks at the Penn State Circus.
It's great we've achieved such renown.
But my talk was just getting started,
When I was told it was time to sit down.
All my best results left unsaid.
I was really quite perturbed.
Perhaps if we held the next circus in Antarctica,
I would get all the time I deserve.

UMBC, the place to be,
For finite elementers, he or she,
Knowing what's now,
Glowing news of elements in MD.

On the mathematics of two of the founding fathers of the Circus on the occasion of their 75th birthdays.
Jim and Bruce, they got the juice,
They know how to cruise,
In waters Mathematical.
They are in their element,
They do their Theorems cement,
With Proofs pure and economical.
Among ensnaring, snaky integrals,
And choppy, sharp differentials,
They navigate with ease.
Yes, it's all breezy, it's all so easy,
When THEY pull the barge,
Those two Mathematicians at large.
Yes, they can do whatever they please,
They can follow their whim,
They know how to swim, do Bruce and Jim.

Gauss and Seidel had a flair,
For solving their systems with care.
The importance of getting it right,
So the numbers will shed true light;
Of this were Gauss and Seidel aware.

A lovely number born in Greece, ever ready to tease,
PI a maiden of Hellas, toyed with a Syracuse fellow:
"I like being irrational, transcendental and random,
You are so very rational, but can you catch a phantom?"
Ardent Archimedes, in turn set his clever Hunter's snare:
"For a phantom and enigma, a mirage and chimera,
You do cut solid figures, spheres, paraboloids, what not,
They make me hot to trot to untie that Hymen's knot,
Ninety-six elements I hope we merrily shall share,
3 10/71 < PI < 3 1/7,
I'm longing to embrace you in our Seventh Heaven."
Lovely PI was pleased to be so gently squeezed:
"I'll add my elementary and very merry share,
Both Earth and crisp October Air,
But mostly I'll your mind inspire,
In Water and with Fire."

Finite Elementers all felt the urge,
To converge at U. of Pittsburgh.
Their spirits surged, indeed they splurged,
Their thoughts meshed and truly merged.
From clownish pitt-falls all purged,
Finite elements emerged, boldly verged.

Courant, Friedrichs and Lewy
they pitched their tent at night.
They had been drinking heavy,
they couldn't get it ... straight.
They stumbled in the dark,
they couldn't find the light.
They all had lost their spark,
they didn't look too bright.
But then they all sat down
to really start to think.
"We really are all clowns,
we really truly stink."
But they were charismatic,
and in a very blink,
with thinking charact'ristic,
they found the missing link.
"I think we aimed too high
it got to be unstable.
Let's lower our sights,
and start when we are able."
Soon the blinking stars,
their light-rays straight, unbent,
shone down on our three Stars
in their cozy circus tent.
The night was soon all gone,
the sun came up to glance:
Sweet dreams inside their cone,
had Dick and Kurt and Hans.

If you missed it,
It's a pity.
We had quite a circus
In the Motor City.
Zhang and Zhang picked the date
And hosted us at Wayne State.
Ivo was there, it was nice to see.
We listened intently to his philosophy.
Validation and verification
Were his themes.
Without them, we have only
by L. Wahlbin, Spring 2003
On the fair campus of Wayne State,
We were given verification,
That finite elements are, simply, great,
In helping us in validation.
The terminology may be confusing,
Maybe we mean validation
of the methods we try to be using
in modeling verification ?
What we can all validate,
What struck us all uppermost,
What we can all verify:
The Zhang Brothers are super hosts !
by L. Wahlbin, Fall 2002
Mathematicians came; like lambs looking tame,
Not-any lions in sight?
Their theorems true; did though shine through,
As tygers burning bright.
What immortal hand or eye,
Dared frame their fearful symmetry?
Sweet delight of endless strain,
In the furnace of the brain,
Glor'ous mor'ns of sweet delight,
When your thoughts shine bright and right,
Endless nights of strain and pain,
When your brain goes down the drain.
Is sun rise to eternity,
Infinities of elegance,
Grace dancing Finite Elephants.

A Circus at Maryland
Is a pleasant affair.
You walk to the Math Home
And climb up the stairs.
Mathematics will greet you;
It's all in the air.
Old and New Friends will meet you.
Yes, it's that atmosphere.
If I were an M.D.
Healing Body and Soul:
A Circus at MD
Prescribed, makes you whole.
A Circus at Maryland
Is indeed a Most Pleasant Affair.

Heeding the words of GWB,
Continuing on our path,
A reduced but still energetic group
We presented our latest math.
Maxwell, powder, fluid flow,
The applications swirled,
Then engineer Mareno gave
A glimpse of the real world.
Appeared at the circus again,
History is cyclical
And good ideas remain.
by L. Walhbin, Spring 2001
The Rotunda gives the Big Top idea,
The Lecture Room is Top Notch, we agree,
What Perfect a Venue,
for a Circus Adventure;
for algorithms for DE in DE.

A numerical analyst named Bubba
Had considerable stability trouble.
For some help he was sent
To the circus he went
At a campus named after George W.
To explain he was offered the floor
His ideas were splattered with gore.
With his scheme inconsistent
His errors were persistent
At the end he was thrown out the door.
by R. Falk, Spring 2000
When the Rodeo joins the Circus,
It's an event you shouldn't miss.
It's a time to learn of new results
And a chance to reminisce.
The Circus founders knew it
And were there, just as long ago
To see Finite Elements still going strong.
Was there ever a doubt that would be so?
by L. Wahlbin, Fall 1999
The Millennium closes,
And so will this Circus;
Are Foundations done Right for the next thousand years?
Is reasoning Bright,
Are arguments Tight,
Will they Live in the next thousand years?
When Work sheds Light,
And is Bright and is Right,
It SHINES, through the next thousand years.
by R. Falk, Spring 1999
We got the order of speakers at the first circus
By drawing numbers from a hat.
In recent times we've gone high tech
Using a random number generator to do that.
Some complained, so Doug's computer
Now makes the sounds of days gone by.
If he can make it look like Mary Wheeler
We old-timers may start to cry.
Author's notes: 1. In the early circuses, Mary Wheeler was chosen
to draw the numbers.
2. This poem provides an updated ending to the poem of Fall 1996.
by R. Falk, Spring 1998
It was the first circus ever in Denver
And Leo put on quite a show.
His web site had all the info
And the signs told you where to go.
He got the sun to shine on the Rockies
And the snacks were the best and most.
If Leo would only reimburse my airfare,
I'd make him permanent circus host.

In the land of magic and mythica,
Laid I mine eyes on the maiden of Ithaca.
I followed her to where she did dwell
In the shimmering kingdom they call Cornell.
A posteriori estimates at her feet did I lay,
Logarithms for her love I did slay.
Domains I decomposed, to amuse here
Secrets of superconvergence did I peruse her.
I hoped to win her over this way,
But my heart sank when she did say:
"Finite elements do nothing for me
I care not a whit for hp...
"If my hand 'tis your wish to secure,
Try not to be such a bore.
There's one big mistake you're making, pal...
This lady's a finite difference kinda gal!"
by D. French, Fall 1997
The time to discuss finite elements once again came around;
The circus was in Ithaca where fall colors could be found.
Alas, many of the usual performers did not appear
But we still gave our talks and they were all perfectly clear.
The lectures were excellent as we all would attest.
Lars vigorously chased that nasty logarithm pest,
John Osborn explained how badly our method could perform,
And from Jinchao Xu a new multigrid algorithm was born.
But the conference was quieter without Ivo to run the show:
No clapping or yelling to keep us all in tow.
His questioning and badgering were all part of the game
And he would not let us forget the L-shaped domain.
The Cornell circus will soon come to an end;
We have now shown where all our approximate solutions will tend.
So back to our homes we must now go
To refine more meshes before the next circus show.
by R. Falk, Spring 1997
The circus in the Big Apple,
I knew it was meant to be,
When Olof showed his unstructured mesh
And it was a map of NYC.
by R. Falk, Fall 1996
We used to determine the order of speakers
By drawing numbers from a hat.
Now we use a laptop computer
And random numbers to do that.
Someday, we may only have a virtual circus,
Connecting only by computer and phone.
I knew when I let those new guys run the circus
They would not leave well enough alone.
by R. Falk, Spring 1996
We came to South Carolina
To a circus hosted by Sue.
She made sure the azaleas were in bloom
And got Hootie and the Blowfish to be there too.
The talks proceeded at a leisurely pace,
An unheard of thirty minutes was each speaker's due.
It seems that all is well in the finite element world
Except for Ivo, who was home with the flu.
by R. Falk, Spring 1993
OK, Ivo, so it's a little terse.
Be grateful you are getting any verse.
Author's note: This poem was written under extreme pressure from our peerless leader.
