By the Numbers
are used to measure the impact of an author's
academic publications by quantifying, in various ways, the number of
that they generate.
The following were measured on June 14, 2022 using
h-index is 30,
which means that 30 of my papers have been cited 30 or more times.
is 63, which means that 63 of my publications have been cited 10 or more times.
The following were measured on August 14, 2019 using
Publish or Perish
using data from
is an alternative to the h-index.
g-index is 55,
which means that 55 of my publications have together been cited a total
of 552=3,025 times.
is a version of the h-index that normalizes for
number of co-authors per paper so that the impact of scholars in different
disciplines can be compared.
My hI,norm-index is 24.
is a version of the h-index that normalizes for length of career.
My hI,annual-index is 0.59,
which means that I have published an "impactful" paper (defined
to be those that have accumulated enough citations to be included in
my h-index) every 1.7 years on average.
is a measure of excess citations ignored by the h-index.
My e-index is 40.78.
Your Erdös number
is defined as follows.
Paul Erdös has Erdös number 0.
If the smallest Erdös number of the coauthors of
your research papers is i, then
your Erdös number is i+1.
My Erdös number is 3,
at least four different ways:
Paul Erdös, Endre Szemerédi, Georg Schnitger,
Paul Erdös, Jeff Shallit, John Sorenson,
Paul Erdös, Carl Pomerance, John Sorenson,
Paul Erdös, Michael Saks, Piotr Berman,

Your Bacon number
is defined as follows.
has Bacon number 0.
If the smallest Bacon number of the actors in movies
in which you have acted is i, then
your Bacon number is i+1.
My Bacon number is 3 because I was
an extra in the film
who has Bacon Number 2 (you can check
this using the Oracle of Bacon).
Your Erdös-Bacon Number
is the sum of your
and your Bacon number.
Very few people have a finite Erdös-Bacon number;
lists just 9 scientists (not including me) and 5 actors.
Since my Erdös number
and my Bacon number are both 3, my Erdös-Bacon
number is 6, putting me alongside luminaries such as
Richard Feynman and
and the actor
I am not worthy.
One of my papers
is mentioned on
p. 666 of the Second Edition of
Knuth, vol. 3
I'm 3 handshakes away from
I've shaken the hand of a man (my father-in-law) who has shaken the hand of a man (a politician
dunning for votes in rural West Virginia when my father-in-law was a kid)
who claimed to have shaken the hand of Abraham Lincoln.
