The Race to Discover Elements

To finish at the podium,

To be by posterity told,

Discount your rival Na,

Heed not of growin Au.

Red-light any parsimony;

Stay pro-chance, not Sb.

May the best-ran win!

They who delve righ Sn.

Get off the A axis,

And climb up the Z:

Isotopes in chemical praxis

Are cheap as pencil Pb.

Let minions envFe your den,

Who lick solvents with W.

May the best lab win!

Which doesn't pack i Sn.

Your offer to the Table
Is glory ripe for pilfer
By those that are unable,
Sure as Hg's quickAg.
Publish for credit proper,
And history shall be your Cu.
May the best jab win!
That in time go Sn.

Limerick #41: Loren(t)z

There was an old physicist called Lorenz,
Not to be confused with Lorentz.
On one's gauge we depend,
The other lengths shortened.
(Then seeded chaos a second Lorenz.)

Clerhiews #19--21: Chaucer

Geoffrey Chaucer
Is a double-crosser. 
One moment on the Path of Life, 
The next on the bath of wife. 

Geoffrey Saucy Chaucer
Sported a single flaw, sir. 
Sometimes -- on the pH scale --
He tended to a basic tale. 

Geoffrey Chaucer
Is no pauser. 
He'd recount at a canter,
Bury the average ranter.

Time flies like an arrow. Fruit flies like a banana.
- (attributed to) Groucho Marx.

Drosophila bifurca is a species of fruit fly. Males of this species are known to have the longest sperm cells of any organism on Earth—5.8 cm long when uncoiled, over twenty times the entire body length of the male.
- Wikipedia.

Certainly, Mr Marx,
Your fruit flies
Do a banana like.
Yet their hallmark's
That their seed flies
Like a lightning strike.

No, You Mind the Gap

Shall you this line catch again?
Or did you shunt and passage end?
'Tis three past twelve; I here remain.

Tell me not I wait in vain.
I know not all the routes you wend;
Shall you this line catch again?

As a refrain is a city train
On whose return I may... depend?
'Tis four past twelve -- I here remain.

How lose a briefcase in a refrain?
This far th' simile can't extend.
Shall you this line catch again?

Stand and count I each sand grain
That descends to my doom portend:
'Tis five past twelve! I here remain.

Is it your toot my ears attain?
To be tardy did you intend?
'Tis far past twelve, I here remain
So you this line catch again.

Rhymer's notes. The villanelle soars in One Art and Are you not weary of ardent ways, and perches highest at Do not go gentle into that good night. Line 16 was thrice composed. First it was through a misunderstanding of the rhyme scheme 'Is that your roll round the bend?'. Then it became 'Arrive you at last at the quatrain' before a less meta option was picked.
