ACKNOWLEDGMENTS
My greatest institutional debt is to the Social Sciences and
Humanities Research Council of Canada, not only for financial sup-
port of the research required for this book but for their generous and
consistent support of my work since graduate school. Without the
many research grants I have received, this work would have taken a
lot longer than it has. . . which means it might never have been com-
pleted. I would also like to thank the Philosophy Department at the
University of Toronto for financial support in preparing the manu-
script for publication.
Personally, my greatest thanks go to Colin Howson, who was
relentless in pestering me to both start and complete the book. His
sense of humour and good advice are unsurpassed, and I am grate-
ful beyond words to be the beneficiary of both. Because the book
is a combination of ideas and material that have been reconfigured
from past work as well as new ventures, the number of people who
have contributed, in one way or another, to the end product are too
numerous to mention. Peter Ohlin has been encouraging all the
way and over a very long period of time. I am also grateful to par-
ticipants at all the many talks and conferences, to referees for written

comments on earlier versions of this work that appeared in journals,
and of course to the referees for the book manuscript itself. I have
benefitted enormously from all of their input. Special thanks for vari-
ous comments, suggestions, and conversations about specific issues/
arguments that have made their way into the final manuscript go to
Sorin Bangu, Robert Batterman, Paul Humphreys, Wendy Parker, and
Eran Tal. The first version of the work on simulation was presented
at the Oberlin Colloquium in the Philosophy of Science held in April
2008, and I would like to thank Martin Jones for the invitation and
his generous hospitality. Other parts were presented at a workshop in
June 2008 and a conference in June 2011 at IHPST Paris, where I was
the beneficiary of the hospitality of Anouk Barberousse, Jacques
Dubucs, Marion Vorms, and Julie Jebeile. Themes and ideas from
chapter 2 were presented at The Twenty-fifth Annual International
Workshop on the History and Philosophy of Science entitled
“Mathematical Knowledge and its Applications.” The workshop was
in honour of Mark Steiner and held at Tel Aviv University and the
Van Leer Institute, Jerusalem, December 12-14, 2011. I would like
to thank the organisers, Yemima Ben Menachem, Leo Cory and Carl
Posey for their hospitality, and Mark Steiner for his generosity over
the years. The material on simulation and the Large Hadron Collider
was presented at a conference on methods of data collection held in
March 2013 and sponsored by the University of Wuppertal group
on history and philosophy of particle physics. I would like to thank
Koray Karaca and all of his colleagues there for their discussion and
feedback. Last but not least I would like to thank Emily Sacharin at
Oxford University Press for her expert help with various administra-
tive issues, Molly Morrison for her efficiency on the production end
and Kevin Kuhl for compiling the index.
