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.
