Found by a random web search for "Math Limericks", these are by Bruce Elliot

deBroglie, caught quite unawares,
Observed a mixed state of affairs:
'Twas Schroedinger's cat
Who quietly sat,
While running away down the stairs.

A Brief History of Gravity

It filled Gallileo with mirth
To watch his two rocks fall to Earth.
He gladly proclaimed,
"Their rates are the same,
And quite independent of girth!"

Then Newton announced in due course
His own law of gravity's force:
"It goes, I declare,
As the inverted square
Of the distance from object to source."

But remarkably, Einstein's equation
Succeeds to describe gravitation
As spacetime that's curved,
And it's this that will serve
As the planets' unique motivation.

Yet the end of the story's not written;
By a new way of thinking we're smitten.
We twist and we turn,
Attempting to learn
The Superstring Theory of Witten!

The graviton's something unique,
A particle many would seek.
To Earth we are stuck
It seems, more by luck,
For its coupling's exceedingly weak!

By Edward H. Green
The first law of Newton I sing
My voice has a relevant ring:
"An object left free
Of hassles will be
Engrossed in just doing its thing."

My twin is much younger than I
He's travelled a lot, that is why
If I had the brain
I'd be glad to explain
But Einstein I'm not, so why try?

It is worth noting that the page I found these limericks on did not have the disclaimer that comes with pealco's writeup - I did attribute authorship and picked the ones I found most amusing (from a selection far smaller that the one below)

So it ain't my fault.
