Yiassou Antreas:
For your information, the foregoing was written (and performed) by me on the occasion of the Number Theory Conference held at Caltech in June 1955.
My verses stimulated some unknown bard to post the following lines on the bulletin board at Cambridge University in 1973:
What Tom Apostol Didn't Know
Andre Weil has bettered old Riemann's fine guess, By using a fancier zeta of s, He proves that the zeros are where they should be, Provided the characteristic is p.
There's a good moral to draw from this long tale of woe That every young genius among you should know: If you tackle a problem and seem to get stuck, Just take it mod p and you'll have better luck.
In a telephone conversation with Tom Apostol in 1990, Saunders MacLane claimed to be the author of the two verses posted anonymously in Cambridge. MacLane has since added the following new verses:
What fraction of zeros on the line will be found When mod t is kept below some given bound? Does the fraction, whatever, stay bounded below As the bound on mod t is permitted to grow?
The efforts of Selberg did finally banish All fears that the fraction might possibly vanish. It stays bounded below, which is just as it should, But the bound he determined was not very good.
Norm Levinson managed to show, better yet, At twotoone odds it would be a good bet, If over a zero you happen to trip It would lie on the line and not just in the strip.
Levinson tried in a classical way, Weil brought modular means into play, Atiyah then left and Paul Cohen quit, So now there's no proof at all that will fit.
But now we must study this matter anew, Serre points out manifold things it makes true, A medal might be the reward in this quest, For Riemann's conjecture is surely the best.
MacLane may have written more verses that I don't know about.

Thanks, Tom!

PS: The story of the long Greek (and others) surnames truncation in the States (Apostolopoulos > Apostol):
In the following article: Kageleiry, Jamie: What Hardly Anyone Knows About Ellis Island. The Old Farmer's Almanac 200(1992) pp. 76  79
we read how the immigrants' names got transmogrified by officials at Ellis Island (during the years 18921954)
Some examples of long surnames: Andrjuljawierjus  Grzyszczyszn  Koutsoghianopoulos  Zemiskicivicz this is Greek
