Summary of the impact
By using the progress of his own research over the course of a year as a
major narrative theme, in Finding Moonshine Marcus du Sautoy
provides the public with unique insight into the content and nature of his
mathematical research programme. The success of the book, published in
2008, in conveying the essence of cutting edge research, in elementary
terms, attracted the attention of broadcasters and policymakers and
provided a platform from which du Sautoy has been able to expand his
public engagement activities to reach millions of people through TV,
radio, public lectures, social media and interactive projects. His three
part documentary The Code stimulated over a million viewers to
play Flash games based directly on mathematical concepts. The phenomenal
success of his unique brand of engagement in awakening an interest in
mathematics, in both young and old, has had a great impact on society.
Underpinning research
Marcus du Sautoy has been at the University of Oxford since 2001, first
as a Royal Society University Research Fellow (until 2005), then as
Professor of Mathematics (20058) and, since 2008, as the Charles Simonyi
Chair for the Public Understanding of Science. In the period 20056, du
Sautoy's research programme, centred on zeta functions and Higman's PORC
conjecture.
The zeta function of a group
G is defined as the sum of the
Dirichlet series whose
n^{th} term is
a_{n}n
^{s}
where
a_{n} is the number of subgroups of index
n
in
G. Such zeta functions have an Euler product decomposition in
which the
plocal factor is the zeta function enumerating subgroups
of
ppower index in
G. Nilpotent groups are natural objects
of study in this context because of their polynomial subgroup growth. Du
Sautoy's work with Grunewald (HeinrichHeineUniversität Düsseldorf) shifted
the paradigm of comparison from analytic number theory to algebraic
geometry, specifically zeta functions associated to algebraic varieties. The
mathematical significance of du Sautoy's programme of work with Grunewald
was recognized by his invitation to speak at the International Congress of
Mathematicians in Zürich in 2006. The corresponding paper, [1], reports on
"progress and problems concerning the analytical behaviour of the zeta
functions of groups and rings" and provides a technical mathematical
presentation of this strand of the research described in
Finding
Moonshine.
Another strand of du Sautoy's research programme during 20056 concerned
his conjecture that all zeta functions of groups satisfy functional
equations. However, during the period, explicit calculations uncovered a
counterexample. The mathematical details are published in [2].

Details of the impact
Published in 2008, Finding Moonshine created a channel via which
du Sautoy's research has had huge impact on society, stimulating interest
in, and engagement with, mathematics. The ultimate beneficiaries have been
millions of members of the general public whose mathematical curiosity has
been awoken.
Finding Moonshine provides the general public with a unique
insight into mathematical research. As the story of the classification of
finite simple groups unfolds, du Sautoy charts the progress of his own
research, month by month, during the year following his 40th birthday. Its
publication cemented Marcus du Sautoy's position as an outstanding
expositor of mathematics and provided a platform from which he expanded
his public engagement activities. Millions of people have subsequently
watched his TV shows, listened to his radio programmes, played his Flash
games and interacted through Facebook. He has been able to use his
position as a leading mathematician and public figure to engage with
Government. Throughout he has maintained close contact with his audiences
and developed new ideas through more intimate activities such as `Maths in
the City' and `Pi Day'.
How research underpins impact
Marcus du Sautoy's second popular book, Finding Moonshine: A
Mathematician's Journey into Symmetry was published in 2008.
Although primarily concerned with the story of the classification of the
finite simple groups, du Sautoy's own research is central to the
narrative. The story begins in 2005, on his 40th birthday, and uses the
literary device of being divided into twelve chapters, one for each month
of the year. Amid many diversions into the (often colourful) lives of
famous mathematicians and stories of major mathematical discoveries, it
has two narrative strands. The first is the story of the classification of
the finite simple groups. The second is the progress, month by month, of
du Sautoy's own research. As part of this second strand, he describes the
problems that he is working on and something of the process of solving,
or, in the case of the problem that he first describes, not solving, them.
He describes Higman's PORC conjecture and his growing scepticism about its
validity. We also see his programme develop: he and a research student
demolish one of his conjectures by exhibiting a group for which the
corresponding zeta function does not satisfy a functional equation — a
concept elegantly explained in terms of palindromic symmetry — as the
conjecture predicts, and so the question is refined. His research, and the
process of research, are thus brought directly to the reader. Crucially,
the book demonstrated that, rather than cherrypicking pieces of
mathematics that are easy to explain, du Sautoy is able to explain the
mathematical concepts that lie at the heart of his research in a way that
is accessible and engaging. The next step was to provide his audiences
with the opportunity to go beyond the passive process of reading and to
actually participate in the mathematics. This required multiple media, but
combining his abilities as a broadcaster with his deep knowledge and
boundless curiosity as a researcher he developed ideas based on these same
mathematical concepts into TV shows with accompanying webbased Flash
games.
Nature and extent of impact.
The impact of Finding Moonshine has been both direct and indirect.
It has been translated into ten languages and has sold over 62,311 copies
worldwide [A]. The Fields medallist Professor Sir Timothy Gowers wrote in
his review for the Times Higher Educational supplement [B]: "If
you are genuinely curious to know what it is like to be a mathematician,
there is now a better way of satisfying your curiosity: read Finding
Moonshine." The publication of the book gave du Sautoy the platform
to promote and explain the importance of group theory to a wide audience,
with diverse mathematical backgrounds, as evidenced by many of the
comments from readers left on du Sautoy's blog [C]:

"I'm a former student of maths. I abandoned my studies 20 years
ago. Recently, my wife gave me your book about symmetry as a present.
Now I am enjoying the reading greatly. You awakened in me a kind of
longing for maths. A math worm that was sleeping for years. [...]
I just wanted to thank you for making Mathematics so appealing."

Just finished this book. It really is a very good read even for
those who have a little understanding of maths. Considering I only
have a GCSE I didn't find it too bewildering."

"I just finished reading Finding Moonshine in the dead of night
last night :) I so enjoyed it [...] Now I see symmetry
everywhere — what a joy!"
TV and Radio. With the success of Finding Moonshine, du
Sautoy found himself in increasing demand as a broadcaster. A string of
appearances on TV and radio, in which he explained the importance, and
excitement, of mathematics followed, including:
 The Story of Maths (4 part series on BBC4, Autumn 2008): Episode 1,
0.58 million viewers;
 Horizon: How Long is a Piece of String — Presented by comedian Alan
Davies and featuring Marcus du Sautoy on BBC2 on 17th November 2009:
2.11 million viewers;
 Horizon: What Makes a Genius — on BBC2 on 17th February 2010: 1.76
million viewers;
 A Brief History of Mathematics — a ten part series profiling famous
mathematicians on BBC Radio 4 in June 2010.
(TV viewing figures here and below are taken from www.barb.co.uk/viewing/weeklytop30.)
One of Horizon's viewers commented on du Sautoy's blog [C]: "Your
enthusiasm is infectious. I repeated your explanation of Euclid's Prime
Number Proof to my 9 and 12 year olds and they were gripped. I didn't
understand about mathematical proofs until after I left school! Thanks
for a great piece of work."
With such clear evidence of his appeal as a broadcaster and of his
ability to present complex mathematical concepts, right up to the cutting
edge of research, in a way that was accessible to audiences from very
mixed mathematical backgrounds, he next went beyond the traditional format
of these programmes to develop new shows, supported by materials that
exploit a range of electronic media, which appeal to audiences with a much
wider demographic profile. Importantly, the public actively participate in
the mathematics. Building on the success of Finding Moonshine, the
material of these shows is directly based on mathematical concepts,
especially the prime numbers and symmetry that lie at the heart of du
Sautoy's research.
The first such show was The Code, a three part documentary series
on BBC2 which started on 27 July 2011. Viewing figures for the three
episodes were 1.75 million, 1.53 million and 1.33 million. Viewers of The
Code were invited to participate in an interactive mathematical
treasure hunt based on the academic ideas presented in the programmes. The
treasure hunt involved four webbased Flash games, produced by the company
Six to Start, who state [D] "all of the games are tied directly
into concepts shown in the show", focusing on mathematical concepts
such as symmetry and prime numbers, hunting for clues in the programmes,
solving riddles, finding examples of prime numbers in everyday life and
completing a complex mathematical quiz book. They add that over 1 million
people played the Flash games, playing for an average of 24 minutes, and
more than 100,000 took part in the treasure hunt challenge. The level of
engagement by viewers was staggering, as all of the elements of the
treasure hunt involved dedication and complex mathematical concepts.
According to the Six to Start Executive, reported in an external
blog [E], there are "300,000+ interactions on the Facebook fan page,
1000+ photos, videos, 3D models, and a wiki with 100,000 views and 2000+
edits — all created by users". An appraisal of the treasure hunt on
the same blog emphasises the significance of the engagement: "The whole
thing was really involved and quite complex, not to mention on a
traditionally unpopular subject, maths, so over 100k players for the
metapuzzle is impressive [...] it does seem like quite an
achievement."
The opportunity to engage a quite different kind of audience arrived when
du Sautoy was chosen as copresenter of the comedymaths show, Dara Ó
Briain's School of Hard Sums. First aired on Dave on 16^{th}
April 2012, it attracted 1.7 million viewers. According to the Executive
Producer of the show [F] "[it is] the most watched completely new
title in the history of the channel" with "more than double the
normal ratings in its slot with 555,000 viewers for episode one".
She adds that proof that viewers have engaged with the maths that du
Sautoy introduces on the show is that "the homework questions were
viewed a staggering 442,124 times! The title accounted for almost a
quarter of all page views when it was on air (2,030,796 total page
views) and has recently been recommissioned by Dave".
Recognition of the huge educational potential that du Sautoy had unlocked
came in a speech [G] of Michael Gove, Secretary of State for Education: "Computer
games developed by Marcus Du Sautoy are enabling children to engage with
complex mathematical problems that would hitherto have been thought too
advanced. I am sure that this field of educational games has huge
potential for maths and science teaching".
Maths in the City and Pi day. Public engagement activities must be
continually refreshed if they are to continue to have impact. Recognising
the importance of a twoway dialogue, and also the value of smaller scale,
more intimate, projects than his TV shows, in 2010 du Sautoy began working
with a team from the University of Oxford's Department of Continuing
Education to create a way to reach out to the public with maths, ensure
engagement with the subject and open a twoway dialogue with participants.
The result was the Maths in the City project: a website with a user forum
heavily involving social media, and walking tours around Oxford and London
pointing out examples of maths in everyday life. Just as when he describes
outings with his son in Finding Moonshine, symmetry, inevitably,
plays a central role. Du Sautoy helped to design the free tours and
materials and led some of them before handing over to students from the
Oxford Mathematical Institute, whom he had trained. Funded by the EPSRC,
the tours, which were attended by adults and school groups from as young
as Key Stage 3, were a huge success with over 2500 people engaging via
social media, over 460 people attending the tours and over 130 examples of
`maths in the city' from around the world posted on the website. The Maths
in the City project has been so successful, that the same format is being
used in the training of mathematics teachers in China.
Du Sautoy has continued to work with the University of Oxford's
Department of Continuing Education to create events that not only broaden
the knowledge of the participants, but also their approach to maths.
Through the use of online communication, these events allow participants
to engage both during and after the live event. The first event, Pi day,
which took place in March 2013, made innovative use of social media in
arranging for participants to `rediscover Pi' through experiments.
According to http://oxfordconnect.conted.ox.ac.uk,
around 2000 participants from 17 different countries took part.
Sale of Groups and Common Hope. In a completely different
direction, in October 2012, du Sautoy offered opportunities to name
nilpotent groups appearing in his research in recognition of contributions
to charity. Through this direct application of his research, du Sautoy
sponsors the Common Hope Charity that supports orphanages in Guatemala.
Amid widespread, and very positive, publicity for mathematics, such as the
article [H] in The Times, he also offered one of the groups to
Queen Elizabeth II in honour of her Diamond Jubilee.
