SUMMARY:Geometry and mathematics for the technical and visual arts at the

DESCRIPTION:Although an increasing number of printed books around 1500 ass
essed geometry and arithmetic\, specific evidence of their applications in
the visual and technical arts is difficult to locate. Ten percent of incu
nabula addressed science\, and were consulted by readers of books on music
\, as well as the artes techinae. Luca Pacioli’s Summa (1494) is an exam
ple of the developing mathematical discourse that taught argumentative rea
soning and other practical and theoretical applications of mathematics in
general. A century after Francesco di Giorgio’s 1478 ‘Opusculum de arc
hitectura\,’ Ignatio Danti complained of the reduction of mathematical s
ciences among natural philosophers\, such that “the little which remains
to us is limited to some practical aspects learned from the mechanical ar
tificers.” The development of mathematical studies chiefly among artist/
engineers was rooted in the traditions of intellectual ‘omini pratici’
dating back to the treatises of Lorenzo Ghiberti\, Leon Battista Alberti\
, Filarete\, Piero della Francesca\, and Francesco di Giorgio. Followers o
f this scholarship\, generally around 1500 in the region from central Ital
y to southern Germany\, believed that the universal form and function of N
ecessity required proportional estimation and numerical definition. Thus\,
approaches to problems in statics and dynamics often relied on arithmetic
and Euclidean geometry\, at a time when mathematical solutions were also
sought for ancient Greek problems rational numbers could only estimate (eg
. doubling the cube\, squaring the circle\, trisecting the angle). I will
use examples in the work of Leonardo da Vinci and his contemporaries as ev
idence of the central role of proportional geometry and arithmetic among a
rtist/engineers for solutions in the natural sciences and practical arts.\

DESCRIPTION:How can diagrams account for the correctness of algorithms? Wr
itings composed in China between the 11th and the 13th centuries and devot
ed to algebraic equations illustrate an unexpected answer to this question
. They contain geometrical diagrams whose captions establish a specific co
nnection between the diagrams and the algorithms in relation to which they
are given. The talk will analyze the context in which these diagrams\, in
and of themselves\, formulate an argument. It will further examine the fo
rm of algebraic proof in an algorithmic context that replaces these diagra
ms when later on\, they disappear from writings devoted to algebraic equat
ions.\nSpeakers:\nKarin Chemla (CNRS)

DESCRIPTION:In his seminal work on numeracy Keith Thomas noticed the diffe
rent status of different forms of numbers. He quoted Gervase Markham’s 1
635 Honest Husbandman ‘there is more trust in an honest score chaulkt on
a Trencher\, then in a cunning written scrowle\, how well so ever painted
on the best Parchment’. This paper begins to explore this issue Thomas
raises by considering how speaking\, reading and writing numbers was taugh
t in seventeenth and eighteenth-century England. Most published arithmetic
s included numeration tables that were designed to help readers convert sp
oken numbers to written numbers and vice versa. The table played various r
oles in the explanations of place value\; at times it was seen to be a sub
stitute for a master\, and in some contexts the language of the body was u
sed to help readers navigate the table. A few authors were particularly ke
en to help readers understand very large numbers. Numeration tables also a
ppeared in manuscript arithmetics and the last part of the paper looks at
the heated controversies surrounding handwriting numbers in this period.\n

SUMMARY:Insights into the long “genesis” of Dedekind’s lattice theor

DESCRIPTION:In two papers published in 1897 and 1900\, Richard Dedekind pr
esents and studies a new notion\, the Dualgruppe\, which corresponds to w
hat is today called a “lattice”. This concept was the result of a long
and\, as Dedekind tells us\, strenuous research process that lasted aroun
d twenty years.\n\nNot only is it possible to identify\, in Dedekind’s p
ublished works\, the major steps of his work towards the notion of Dualgr
uppe\, we also can follow the research process in his – rich and well-pr
eserved – Nachlass. \n\nIndeed\, in Dedekind’s Nachlass\, one can f
ind several hundred pages of research\, notes and computations leading to
the slow\, progressive elaboration of the notion of Dualgruppe. These co
mputations and the stepwise generalization of the concept largely disappea
r from the published exposition of the theory\, which appears to be very g
eneral and abstract. The drafts highlight the working process and Dedekin
d’s exploration\, through computations\, tables\, half-written papers...
\n\nUsing Dedekind’s Nachlass\, I will show how Dedekind gradually bui
lt his Dualgruppe theory through many layers of computations\, often rep
eated in slight variations and attempted generalization. Insofar as these
drafts were working tools for Dedekind\, by studying the concealed strata
of mathematics they contain\, I wish to reveal and clarify the preliminary
and intermediary states and steps of the mathematical research during the
elaboration of the concept of Dualgruppe. \n\nWhile focused on Dedekind
’s work\, here\, I also hope to stress the fruitfulness\, for the histor
y of mathematics\, of taking into account the various notes and drafts le
ft by mathematicians.\nSpeakers:\nEmmylou Haffner (Bergische Universität

the Göttingen State and University Library. It was built upon the rich i
nventory that was created from collections of documents\, manuscripts\, an
d other archival resources\, donated as bequests (Nachlässe) to Göttinge
n’s university library. For example\, the Nachlässe of Abraham Gotthelf
Kästner\, Tobias Mayer\, Carl Friedrich Gauss\, and Bernhard Riemann as
well as the so-called Mathematiker-Archiv\, an archival collection of pape
rs of notable mathematicians started by Felix Klein\, were already present
in Göttingen. Today\, the archive houses a vast collection of documents
and archival material of more than 60 mathematicians.\n\nIn this talk\, I
will address present activities at the archive and will provide some examp
les in order to give an impression of the value of the vast collection for
the history of mathematics. Moreover\, I will share some ideas on future
projects.\nSpeakers:\nKatharina Habermann (Universität Göttingen)

SUMMARY:Justification of axioms: a neglected topic in the history of mathe
matics? - Ralph Krömer (Bergische Universität Wuppertal)

DESCRIPTION:In joint work with Hans-Niels Jahnke (Universität Duisburg-Es
sen)\, we investigate the issue of justification of axioms in mathematics\
, from ancient Greek geometry to current debates on set theory\, category
theory and the foundations of mathematics. The aim of the talk is not to g
ive a complete history of the phenomenon but to highlight its relevance (n
ot sufficiently taken into account in the existing literature\, in our opi
nion) by focussing on some particular cases. We take a look at Proclus’s
discussion of Euclid’s axioms and postulates (especially\, but not excl
usively\, the parallel postulate)\, at how Archimedes and much later Klein
discuss the archimedean axiom\, and finally at Penelope Maddy’s account
of axioms of set theory\, inspired by Zermelo’s remarks on the axiom of
choice. The last case leads us to similar considerations concerning the r
ole of category theory in the foundations of mathematics.\nSpeakers:\nRalp

SUMMARY:"Black strokes upon white paper": changing attitudes towards symbo
lic algebra from the 19th into the 20th century - Christopher Hollings (Un
iversity of Oxford)

DESCRIPTION:During the first half of the nineteenth century\, a debate too
k place amongst British mathematicians concerning the nature of the symbol
s used in algebra: did they necessarily stand for numbers\, or could they
simply be manipulated according to specified rules\, with interpretation (
if any) coming later? Critics of the former point of view decried the res
triction that would thereby be placed upon the use of algebra\, whilst tho
se of the latter saw it as being ill-justified and often too far removed f
rom concrete examples. For a range of reasons\, both educational and phil
osophical\, a fully abstract 'symbolical algebra' never appeared in ninete
enth-century British mathematics\; 'abstract algebra' as we now know it de
rives from largely German sources at the end of the century. Nevertheless
\, as the abstract point of view came gradually to dominate algebra during
the early decades of the twentieth century\, similar debates took place t
o those of a century earlier. This time\, however\, the abstract approach
was received more sympathetically. In this talk\, I will contrast these
changing attitudes towards abstract/symbolic algebra\, and address the que
stion of why this approach became more acceptable in the twentieth century
