This equation translates to:
Integral z-squared dz
Before you send me critical emails, I already know that the "log" is "natural log" or "log to the base e". This limerick apparently dates from that period in history when physicists understood the convention that "log" without qualification meant "natural log" and that if any other kind of log was meant, you had to specify its base explicitly in the notation.
From 1 to the cube root of 3
Times the cosine
Of three pi over 9
Equals log of the cube root of e.
The next equation limerick is easier. It was devised
by Leigh Mercer (1893-1977), and appeared in
Word Ways, 13, 1, (Feb, 1980), p. 36.
Mercer also devised one of the most famous palindromes:
"A man, a plan, a canalPanama." Mercer's biography
can be found in Word Ways, 24, 3.
(August 1991), p. 131-138. He was a
London panhandler who drew caricatures on sidewalks
12 + 144 + 20 + 3√4
——————————————————— + (5 × 11) = 92 - 0
A dozen a gross and a score,
I suppose we should include here Mercer's example of how to make a
limerick from a number, 1,264,853,971.2758463, or vice versa.
Plus three times the square root of four,
Divided by seven
Plus five times eleven
Is nine squared and not a bit more.
One thousand two hundred and sixty
four million eight hundred and fifty
three thousand nine hun-
dred and seventy one

Here's some classic math limericks.
|A Möbius stripper.|
Cover of Science Askew
by Donald Simanek
and John Holden.
A mathematician confided
That a Möbius strip is one-sided.
You'll get quite a laugh
If you cut it in half.
For it stays in one piece when divided.
A burlycue dancer, a pip
Here's two original mathematical limericks by Donald E. Simanek.
Named Virginia could peel in a zip;
But she read science fiction
And died of constriction
Attempting a Möbius strip.
Cyril Kornbluth (1923-1958)
Null vectors have zero projection.
So you ask, "What can be their direction?"
They point any which way.
"That's magic!" you say?
Not really; it's just misdirection.
The Professor said, "Now I'll tell you
Finally, Martin Gardner contributes this one to our collection.
A fact known to only a few
Men and women alive.
Two plus two equals five!
For large enough values of two."
The Unending Mystery of π
π goes on and on and on,
And e is just as cursed.
I wonder, "How does π begin
When its digits are reversed?"
Pondering the infiniteness of π, Patrick Killen of Australia dashed off this limerick.
An adventurer once tried to fly
All the way to the far end of π.
A true mathematician
Won't attempt such a mission,
For such wishin' is just pie in the sky.
Martin Gardner revealed to me this curiosity of numerology:
Write out the alphabet starting with J:
Erase all letters that have left-right symmetry (such as A) and count the letters in each of the five groups that remain.
Who would have thought that π was hidden in the English alphabet? Folks addicted to mystical interpretations of mathematics get all excited about such things.
Write out 5 + 5 + 5 = 550 with pencil on paper, an "equation" which is obviously incorrect. But you can correct it by adding just one straight line with the pencil. Better yet, there are two different ways you can do this.
y ¹ f(x)
|This x is a very independent variable.|
Any variable x which refuses to be dependent on any y is
is about as "independent" as it can be.
A problem in number base conversions:
Prove that Christmas = Halloween = Thanksgiving.
Christmas = DEC 25
Certain impressionable minds might assume from this
remarkable exercise in number-base
conversions that there is some mystical significance relating the dates of
Halloween = OCT 31
Thanksgiving = NOV 27
DEC 25 is 25 base 10 or (2 x 10) + (5 x 1) = 25
OCT 31 is 31 base 8 or (3 x 8) + (1 x 1) = 25
NOV 27 is 27 base 9 or (2 x 9) + (7 x 1) = 25
Amoebas make poor mathematicians; they divide to multiply.
Q. What do you get when you cross an anopheles mosquito with a mountain climber?
A: Nothing: you can't cross a vector with a scalar.
Since a homonym (scalar & scaler) is involved, this works only as a spoken joke.
