Yet More chutzpah in
assigning Erdös Numbers
 In our first
web page, it was explained how Erdös Numbers are computed from a chain
of joint papers starting at one coauthored by Paul Erdös. To continue:
Those who gain their knowledge of mathematics from that most reliable medium, the film,
will learn from Good Will Hunting that publication in MIT TechTalk is the absolute pinnacle of
mathematical achievement,
if a little lower in stature than the actual award of a Fields Medal. With the publication of
the
May 17, 1979 issue of
MIT Tech Talk featuring Alexander's exploration of fluid mechanics at MIT my son
Alexander had it made  at least within mathematics.
But it was nice that with assistance from the subeditor of Tech Talk
this issue constitutes a joint publication of Alex
with MIT's latest Field Medallist.

Which Movie Star has the lowest Erdös Number?

Good Will Hunting, was conceived and
scripted in part by Matt Damon.
The technical consulant for that movie 
Dan Kleitman
 was a mathematician with
the notably low Erdös Number of 2  so that
Matt Damon,
emphatically gained the low Erdös Number of 3.
Arguably all those listed on the credits for Good Will Hunting
also gained
a low Erdös Number.

Does Joan Baez have an Erdös Number of 3 ?

Quote from Email:
Lucy Kaplansky was the opening act at a recent concert
given by Joan Baez.
Lucy Kaplansky's father is Izzy Kaplansky.
Izzy Kaplansky is a coauthor of Erdos'.

Do any animals have an Erdös Number ? Is it possible ?

Recent work by animal psychologists showing that not only primates
but even birds have surprising intellectual capacities,
opens the question as to whether nonhumans can boast a Erdös Number.
The answer is indeed yes; the story is however curious.
Jerry Grossman at Oakland University
contributed an article to a Bridge magazine, jointly with Smarty, his wife's horse.
As Grossman (Grossman, Jerrold Wayne) has an Erdös Number of 2, the horse achieved an Erdös Number
of 3.
In keeping with the hardedge, yet generous, approach taken on this site, here are the detailed facts
re Smarty.
A clue/entry in a crossword included in a magazine devoted to Bridge cast aspersion on the Arabian breed.
Smarty, as was his style, expressed gross irritation, and was consoled by Jerry Grossman, who
ghosted a letter of complaint to the magazine. The published letter only featured Smarty's name,
but as this is common practice in "ghosted" books and articles, the joint authorship of this publication is accepted.
And how could one dispute with the principal compiler of
the official Erdös Number Project ?

Did my Partner Acquire an Erdös Number on marriage ?
If Not, How can he/she acquire a finite one?
What if one party to a marriage already has an assigned
Erdös Number
while the other has no finite
Erdös Number.
Does a marriage certificate
signed by both parties, constitute a publication of those two parties,
assigning Erdös Number + 1
to the spouse?
No  a single copy does NOT constitute a publication.
In our opinion only in the case of "serial marriage"  repeated marriages of the same parties 
would the duplicated marriage certificate constitute a publication for these purposes.
Its arguable that in the case of a bigamist, certificates each with different partners names constitute revised editions 
but we won't buy that.
Can Sophie Acquire an Erdös Number ?

Can a character in a novel gain an Erdös Number ?
Clearly the author of a novel can give one of his characters
any such attribute he requires, but an Erdös Number
bestowed by an author will NOT be recognised by this Project.
The work of the author remains a fiction.
We are more flexible than the Erdös Number Project, but not fanciful.
In detail, the Erdös Number Project will only recognise an awardee
whose act of collaboration involved an act of free will on their part.
Few characters in novels possess the philosophical nouce required to escape
the author's direction and to act for themselves.
But
in Sophies World
the character Sophie, with devilish cunning, achieved an act of freewill,
Sophie escaped from the tyranny of her author, The Major, himself a fictional construct of
Jostein Gaarder.
There is a further question: in which world can Sophie  or any other fictional character 
acquire an Erdös Number. For the answer to this question, we await further.
presentations by Jostein Gaarder.

Quintrino Assignment of an Erdös Number
There is a fivefold chain of collaborators linking the author of this site,
Harvey A. Cohen, with Paul Erdös,
In detail, the five chains of collaborators linking Cohen with Erdös are:
 Cohen, H.A.  Bracken, A.J. Doebner, H.D.Schott, R.Janson, S.Erdos
 Cohen, H.A.  Bracken, A.J., Barut, A.O.Wilson, RajMacintyre, A.J.Erdos
 Cohen, H.A.  Bracken, A.J., Rogers, C.Swetits, J.J.Kroo, A.Erdos
 Cohen, H.A.  Bracken, A.J., Vyborny, RLee, P. Y.Chen, C.C.Erdos
 Cohen, H.A.  Bracken, A.J., Hughes, J.W.B.Moshinsky, M.Sharma, A.Erdos
No further proof is required that the topology of this multiple fivefold linkage matches
the sculpture
Quintrino shown to the left:
But this publication is a joint publication of the webmaster, and of
the mathematical sculptor
Bathsheba Grossman
QED: By virtue of this joint publication, Bathsheba Grossman has gained an Erdös Number
of 6.

Note that
successful
claims for
Erdös Number
assignment are invariably
outrageous 
Like the claim that the sum of the (Babe) RuthAron Numbers,
714 and 715, is a backwardsforwardssideways prime:
In detail: 714 + 715 = 1429.
1429, 9241, 1249, 9421, 4129, 4219 are all prime numbers.
As to 1492? That couldn't be more prime in the dictionary sense, despite being an even number,
as it was the year that Columbus 'discovered' America.
What's more, 714 x 715 = 2 x 3 x 5 x 7 x 11 x 13 x 17  the product of the first seven primes. This must be the clincher !!
So we accept
Ivars Peterson's
claim
that 1429 is a backwardsforwardssideways prime,
as we apply
the same principle in assigning Erdös Numbers.
The Basic Rule for Assigning Erdös Numbers Outrageously: If there isn't a chain of
formally mathematical papers connecting the assignee with Paul Erdös
was enough Chutzbah involved in the claim for
it to be taken
{ uproariously }
seriously ???
