Brendan Damien McKay (born 26 October 1951 in Melbourne, Australia) is an Australian computer scientist and mathematician. He is currently an Emeritus Professor in the Research School of Computer Science at the Australian National University (ANU). He has published extensively in combinatorics.

Contents

McKay received a Ph.D. in mathematics from the University of Melbourne in 1980, and was appointed Assistant Professor of Computer Science at Vanderbilt University, Nashville in the same year (1980–1983). [1] His thesis, Topics in Computational Graph Theory, was written under the direction of Derek Holton. [2] He was awarded the Australian Mathematical Society Medal in 1990. [1] He was elected a Fellow of the Australian Academy of Science in 1997, [1] and appointed Professor of Computer Science at the ANU in 2000. [3]

Mathematics

McKay is the author of at least 127 refereed articles. [1]

One of McKay's main contributions has been a practical algorithm for the graph isomorphism problem and its software implementation NAUTY (No AUTomorphisms, Yes?). [4] Further achievements include proving with Stanisław Radziszowski that the Ramsey number R(4,5) = 25; proving with Radziszowski that no 4-(12, 6, 6) combinatorial designs exist, determining with Gunnar Brinkmann, the number of posets on 16 points, and determining with Ian Wanless the number of Latin squares of size 11. [5] Together with Brinkmann, he also developed the Plantri programme for generating planar triangulations and planar cubic graphs. [6]

The McKay–Miller–Širáň graphs, a class of highly-symmetric graphs with diameter two and many vertices relative to their degree, are named in part for McKay, who first wrote about them with Mirka Miller and Jozef Širáň in 1998. [7]

Biblical cyphers

Outside of his specialty, McKay is best known for leading a team [8] of Israeli mathematicians such as Dror Bar-Natan and Gil Kalai, together with Maya Bar-Hillel, who rebutted a Bible code theory advanced by Eliyahu Rips, Yoav Rosenberg and Doron Witztum, [8] which maintained that the Hebrew text of the Bible enciphered predictive details of future historical events. The paper in question had been accepted for publication by a scientific peer-reviewed journal in 1994. [9] [10] [11] Their rebuttal, together with a paper written by an anonymous mathematician, argued that the patterns in the Bible that supposedly indicate some hidden message from a divine source or have predictive power can be just as easily found in other works, such as War and Peace . [12] The discredited theory was taken up by US journalist Michael Drosnin. [13] [14] Drosnin said he was convinced of this theory when one of its exponents stated that the Torah predicted the Iraqi wars. He expressed his certainty publicly that such coded messages could not be found in any other work than the Bible, and, in an interview with Newsweek, he challenged: "When my critics find a message about the assassination of a prime minister encrypted in Moby Dick, I'll believe them." [13]

Rising to the challenge, McKay, employing the same Bible decryption method espoused by Rips' group, quickly found some nine references to Yitzhak Rabin's assassination in Herman Melville's masterpiece. He also showed that the same technique allowed him to find ostensible mentions not only of the assassinations of Martin Luther King, JFK, and Abraham Lincoln [8] but also references to Diana, Princess of Wales, her lover Dodi Fayed, and their chauffeur Henri Paul in the same novel. [15]

This debunking disproof of a theory that the bible encrypts secret messages containing future world history achieved international fame for McKay outside of his specific field of combinatorics. [16] [17] [18]

Azzam Pasha quotation

McKay also uncovered the original source of the Azzam Pasha quotation. The original source, an 11 October 1947 article in the Egyptian newspaper Akhbar al-Yom, was first referenced in an article by David Barnett and Efraim Karsh in the Fall 2011 issue of Middle East Quarterly without reference to McKay. [19] Tom Segev responded in an op-ed in Haaretz that McKay had in fact been the original source of the material and had uploaded it to Wikipedia. [20] McKay had notified the Wikipedia talk page of having found the original interview from which the quote was taken and later provided it to Barnett. According to Karsh, McKay was offered a co-author credit in the Middle East Quarterly article but he declined on the grounds of having a low opinion of the publication. [21]

Further

He gave an invited talk at the International Congress of Mathematicians in 2010, on the topic of "Combinatorics". [22] Notable students include Jeanette McLeod. [23]

The Bible Code is a book by Michael Drosnin, first published by Simon & Schuster in 1997.

In combinatorics, Ramsey's theorem, in one of its graph-theoretic forms, states that one will find monochromatic cliques in any edge labelling (with colours) of a sufficiently large complete graph. To demonstrate the theorem for two colours (say, blue and red), let r and s be any two positive integers. Ramsey's theorem states that there exists a least positive integer R(r, s) for which every blue-red edge colouring of the complete graph on R(r, s) vertices contains a blue clique on r vertices or a red clique on s vertices. (Here R(r, s) signifies an integer that depends on both r and s.)

The Bible code, also known as the Torah code, is a purported set of encoded words within a Hebrew text of the Torah that, according to proponents, has predicted significant historical events. The statistical likelihood of the Bible code arising by chance has been thoroughly researched, and it is now widely considered to be statistically insignificant, as similar phenomena can be observed in any sufficiently lengthy text. Although Bible codes have been postulated and studied for centuries, the subject has been popularized in modern times by Michael Drosnin's book The Bible Code (1997) and the movie The Omega Code (1999).

In the mathematical discipline of graph theory, a wheel graph is a graph formed by connecting a single universal vertex to all vertices of a cycle. A wheel graph with n vertices can also be defined as the 1-skeleton of an (n – 1)-gonal pyramid. Some authors write Wn to denote a wheel graph with n vertices ; other authors instead use Wn to denote a wheel graph with n + 1 vertices, which is formed by connecting a single vertex to all vertices of a cycle of length n. The rest of this article uses the former notation.
