My "nice" and "new" contributions to the Online Encyclopedia of Integer Sequences
NEW AND NOTEWORTHY 18 December 2018
* arXiv versions of [63, 74], Zbl reviews of [63, 70], online version of [71], new papers [38, 69, 72, 73, 74]
|
* Designation of [6] as the 6th most-cited Monthly paper on pi in [xlxvi]'s list of ``pi-star'' papers
|
* Co-author links in [53] to a tribute page for, and in [59] to a paper by, my friend and coauthor Sylvester
Reese, who passed away 21 May 2014
|
*
Link in [54] to Hajja's Zentralblatt review: "The paper under review is
a major contribution to the literature
on the arbelos. For the first
time, someone dares make drastic changes on the Archimedean
configuration..."
|
* Link in [xxxv] to Paul Loya's book "Amazing and Aesthetic Aspects of Analysis." My symmetric formula for pi
(see below) is a "beautiful expression" and "quite astonishing!"
|
*
Belated publication of my solution [21] to my Monthly Problem 11222: An
Infinite Product Based
on a Base; the editor comments
"The proposer's elegant solution covers all cases simultaneously and
efficiently."
|
* Link [xxvi] to Michel Waldschmidt's Bombay lectures on irrationality; he mentions my work on Euler's constant
[5] and gives my geometric proof that e is irrational and my irrationality measure for e [14]
|
* At long last, the MAA has put a citation of [3] in Dunham's book "Euler, the Master of Us All", and PUP has
cited [3] in Havil's book "Gamma: Exploring Euler's Constant" - see [I] and [III] below
|
* Link [xviii] to John Baez's web page This Week's Finds in Mathematical Physics. He displays the infinite products
for e, e^gamma,
and pi/2 shown below, calls them "eerily similar" and a "mystery thrown
down to us by the
math gods, like a bone from on
high", and cites my Monthly note "A faster product for pi ..." [12].
|
* Link [VII] to A. V. Zhukov's book El Omnipresente Número "Pi". My symmetric formula for pi (see below) is an
exhibit in his "museum of elegant mathematics."

|
| If F(n) -> 0, then Euler's constant is irrational, but is not a super Liouville number [10] |
|
| If the graph -> 0 as n increases, then ln(pi) is irrational, but isn't a super Liouville number [13] |
