THE CHEMIST'S RECIPIE FOR CHOCOLATE CHIP COOKIES
The following recipie for chocolate chip cookies recently appeared in Chemical & Engineering News (C&EN, Jun 19, 1995, p. 100). It was attributed to Jeannene Ackerman of Witco Corp.
In a second 2-L reactor vessel with a radial flow impeller operating at 100 rpm add four, five, six, and seven until the mixture is homogeneous.
To reactor #2 add eight followed by three equal portions of the homogeneous mixture in reactor #1. Additionally, add nine and ten slowly with constant agitation. Care must be taken at this point in the reaction to control any temperature rise that may be the result of an exothermic reaction.
Using a screw extrude attached to a #4 nodulizer place the mixture piece-meal on a 316SS sheet (300 x 600 mm). Heat in a 460K oven for a period of time that is in agreement with Frank & Johnston's first order rate expression (see JACOS, 21, 55), or until golden brown.
Once the reaction is complete, place the sheet on a 25 deg. C heat-transfer table allowing the product to come to equilibrium.

Ingredients:
1. 532.35 cm3 gluten
2. 4.9 cm3 NaHCO3
3. 4.9 cm3 refined halite

To a 2-L jacketed round reactor vessel (reactor #1) with an overall heat-transfer coefficient of about 100 Btu/F-ft2-hr add one, two, and three with constant agitation.In a second 2-L reactor vessel with a radial flow impeller operating at 100 rpm add four, five, six, and seven until the mixture is homogeneous.
To reactor #2 add eight followed by three equal portions of the homogeneous mixture in reactor #1. Additionally, add nine and ten slowly with constant agitation. Care must be taken at this point in the reaction to control any temperature rise that may be the result of an exothermic reaction.

Cesium (Burning in the Dead of Night)
(Tune, Blackbird)
Cesium burning in the dead of night.
Take your sky blue lines and start to shine.
All my life,
I was only waiting for the moment you were mine.
Cesium burning on a lake of ice.
Lift your glorious flame up to the skies.
All your life,
You were only waiting for some water to arise.
Cesium burn.
Cesium burn.
Give your light to this coal black night.

Biology Christmas
THE NIGHT BEFORE DEFENCE
(or A Visit From Citrate)
Twas the night before defence, when all through te lab
Not a gel box was shaking, with stain or with MAb;
The columns were hung in the cold room with care,
In hopes that my protein, I soon could prepare;
The post-docs were nestled all smug in their beds,
While extracts of barley muddled their heads;
With the tech in the suburbs and PI the same,
I had just settled down to another video game.
When out of the fridge there arose such a clatter
I sprang from the terminal to see what was the matter.
Away to the cold box, I flew like a flash
But the stench was o'erpowering and I threw up beef hash.
The mould on the dampest of walls were cold
Had the softness of kittens only seven weeks old;
When what to my view, a thing I despise
But a half eaten sandwich and four tiny mice;
With a little old scientist, so lively and galling,
I knew at a glance was Linus Pauling.
More vapid than undergrads, his charges they came,
And he whistled, and shouted, and called them rude names.
"Now, Watson! Now Francis! You strange little modellers!
On Luria! On Bertani! You stupid old broth'lers!
To the top of the bench, to the top of the wall!
Purify! Purify! Purify all!"
As dry heaves before the commitee meeting, bend
A young student's body and his colon distend,
So up their earlobes, acytes they grew,
With a sack full of antibodies, their skin turning blue.
And then, for a second, I heard from the 'fuge,
An unbalanced rotor spinning something too huge.
Where I put down my hand, to better hear the sound,
Came the snapping of sparks from a wire sans ground.
Pauling's hair was al wavy, and I thought I must be sick
`Cause the curls in his hair looked just like a helix.
On an arm load of oranges, he started to snack
An I recalled his fetish with citrate, the quack.
His eyes were all wrinkled, but the cheeks were yet red;
Not too shabby for a man who was several years dead;
The leer of his smile was just a tad scary
And the snow on his rooftop made his head yet quite hairy;
The end of a pipette, he held in his teeth
And a pile of kimwipes lay around his big feet.
He held a small vial of something quite gel-ly,
A mercaptan no doubt, for it make him quite smelly.
He changed `round the columns, adding to the confusion
And I laughed to spite my own paranoid delusion.
A wink of his eye and a rotation of his head,
Told me whatever I drank would soon leave me dead.
He spoke not a word, just buggered up my work,
And dried all my resins, that silly old jerk.
And separating his middle finger from first, fourth and third,
That crazy, old bugger, just flipped me the bird.
He grabbed up his cohorts and ran down the hall,
And away they all flew, letting me take the fall.
That is why, dear Commitee, I am sorry to say,
I need a five year extension, starting today.

Silver Nitrate
(to the tune of "Silver Bells")
Silver nitrate, silver nitrate
it's chemistry time in the lab
Ding-a-ling, with a copper ring
soon it will be chemistry day.
Take your nitrate, in solution
Add your copper with style
In the beaker there's a feeling of reactions
silver forming, blue solution
Bringing ooh's ah's and wows
now the data procesing begins.
Get the mass, change to moles
what is the ratio with copper?
Write an equation, balance it
we're glad it's Chemistry Day.
