DESCRIPTION:Modern mathematics movement of the early 20th century found it
s way into the teaching of mathematics across the world in the early post-
war period\, with Georges Papy and André Lichnerowicz leading the way in
Europe. In Czechoslovakia\, this transformation of mathematics education i
s known as “set-theoretical approach”. Indeed set theory is at the cor
e of Bourbakist transformation of the mathematical knowledge\, as exemplif
ied by their masterpiece Élements de Mathématique\, which became mathema
ticians’ manifesto. In the educational setting\, the adjectives “new
” and “modern” were found more appropriate\, but not so in Czechoslo
vakia. \n \nDirk de Bock’s recent book on the topic (Modern Mathematics:
An International Movement?\, Springer 2023) covers a lot of Modern Math\,
but Czechoslovakia is missing\, and here we are. Czechoslovakia is at the
heart of Europe\, perhaps the heart of Europe. Hence we connect to other
countries: Poland\, Hungary\, Soviet Union\, but also Belgium\, France\, S
weden (marginally)\, the Netherlands\, and Yugoslavia as a very special ca
se.\n\nThis seminar reports on a joint project of Helena Durnová\, Petra
Bušková (Masaryk University)\, Danny J. Beckers (Vrije Universiteit Amst
erdam)\, and Snezana Lawrence (Middlesex University).\nSpeakers:\nHelena D
urnová (Masaryk University)

SUMMARY:The Conceptualization of Mathematics in Pharaonic Egypt - Annette

DESCRIPTION:Ancient Egypt is credited (along with Mesopotamia) for providi
ng the oldest extant mathematical texts. Since the 19th century\, when the
first edition of the Rhind mathematical papyrus was published\, it has he
ld an important role in the historiography of mathematics. One of the earl
iest researchers in the field of ancient Egyptian sciences was Otto Neugeb
auer who has been a major influence on the early development of the field.
While research in Egyptian mathematics initially focused on those aspects
that could be linked to its possible successors in modern mathematics\, r
esearch has also revealed various characteristics that could not easily be
transferred into a modern equivalent. In addition\, research on other sci
ences\, like medicine and astronomy\, has yielded further evidence that a
limitation on those aspects that have successors in modern sciences will a
t best give an incomplete picture of ancient scholarship. This will be exp
lored in a new long-term project\, which is briefly sketched. In the conte
xt of this project\, Egyptian mathematics is also studied. The talk will p
resent an example from the terminology used in Egyptian mathematical texts
to describe this area of knowledge and explore its epistemological conseq
uences for our studies of ancient Egyptian mathematics and aim to situate
it in its ancient context.\nSpeakers:\nAnnette Imhausen (Goethe-Universit

SUMMARY:Mathematising certainty in the 18th century. Jacob Bernoulli’s a
nd Thomas Bayes’ redefinition of “absolute” and “moral” certaint
y through probability calculus - Dinh-Vinh Columban (Université Paris Nan
terre)

DESCRIPTION:In the 17th century\, certainty was still largely organized ar
ound heterogeneous categories such as “absolute certainty” and “mora
l certainty”. “Absolute certainty” was the highest kind of certainty
rather than degree and it was limited to metaphysical and mathematical de
monstrations. On the other hand\, “moral certainty” was a high degree
of assent which\, even though it was subjective and always fallible\, was
regarded as sufficient for practical decisions based on empirical evidence
. Although this duality between “moral” and “absolute” certainty r
emained in use well into the 18th century\, its meaning shifted with the e
mergence of the calculus of probabilities. Probability calculus provided t
ools for attempts to mathematise “moral certainty” which would have be
en a contradiction in terms in their classical 17th-century sense.\n\nJaco
b Bernoulli's Ars Conjectandi (1713) followed by Thomas Bayes and Richard
Price's An Essay towards solving a Problem in the Doctrine of Chances (17
63) reshuffled what was before mutually exclusive characteristics of those
categories of certainty. Moral certainty became mathematizable and measur
able\, while absolute certainty would sit in continuity in degree with mor
al certainty rather than be different in kind. The concept of certainty as
a whole is thus redefined as a quantitative continuum.\n\nThis transforma
tion lays the conceptual foundations for a new approach to knowledge. Know
ledge and even scientific knowledge are no longer defined by a binary mode
l of an absolute exclusion of uncertainty\, but rather by the accuracy of
measurement of the irreducible uncertainty in all empirical-based knowledg
e. Such measurement becomes possible thanks to the new tools provided by t
he emergence of probability calculus.\nSpeakers:\nDinh-Vinh Columban (Univ

DESCRIPTION:Although Green's theorem\, currently considered one of the cor
nerstones of multivariate calculus\, was published in 1828\, its widesprea
d introduction into calculus textbooks can be traced back to the first dec
ades of the twentieth century\, when vector calculus emerged as a slightly
autonomous discipline. In addition\, its contemporary version (and its de
monstration)\, currently found in several calculus textbooks\, is the resu
lt of some adaptations during its almost 200 years of life. Comparing some
books and articles from this long period\, I would like to discuss in thi
s lecture the didactic adaptations\, the editorial strategies and visual r
epresentations that shaped the theorem in its current form.\nSpeakers:\nRo

DESCRIPTION:Mathematicians frequently present their own work in a diachron
ic fashion\, e.g. by comparing their "modern" methods to those supposedly
of the "Ancients\," or by situating their latest theories as an "abstract"
counterpart to more "classical" ones. The construction of such contrasts
entangle mathematical labour and cultural life writ large. Indeed\, it inv
olves on the part of mathematicians the shaping up of correspondences betw
een their technical achievements and intellectual discussions taking place
on a much broader stage\, such as those surrounding the concept of modern
ity\, its relation to an imagined ancient past\, or the characterisation o
f scientific progress as an increase in abstraction. This talk will explor
e the creation and use of such mathematical diachronies\, the focus being
on the works of Felix Klein\, Hieronymus Zeuthen\, and Hermann Schubert.\n

DESCRIPTION:To be a mathematicus in 15th- and 16th-century Europe often me
ant practising as an astrologer. Far from being an unwelcome obligation\,
or simply a means of paying the rent\, astrology frequently represented a
genuine form of mathematical engagement. This is most clearly seen by exam
ining changing definitions of one of the key elements of horoscope constru
ction: the astrological houses. These twelve houses are divisions of the z
odiac circle and their character fundamentally affects the significance of
the planets which occupy them at any particular moment in time. While the
re were a number of competing systems for defining the houses\, one system
was standard throughout medieval Europe. However\, the 16th-century witne
ssed what John North referred to as a “minor revolution”\, as a differ
ent technique first developed in the Islamic world but adopted and promote
d by Johannes Regiomontanus became increasingly prevalent. My paper review
s this shift in astrological practice and investigates the mathematical va
lues it represents – from aesthetics and geometrical representation to e
fficiency and computational convenience.\nSpeakers:\nStephen Johnston (His

DESCRIPTION:The first edition of Thompson’s famous book 'On Growth and F

work in mathematical biology and a revolutionary contribution to the fiel

s who produced the 793 pages of the 1917 edition and 1116 pages of the 194

DESCRIPTION:Computers have been used to process natural language for many
years. This talk considers two historical examples of computers used rathe
r to play with human language\, one well-known and the other a new archiva
l discovery: Strachey’s 1952 love letters program\, and a poetry program
ming competition held at Newcastle University in 1968. Strachey’s progra
m used random number generation to pick words to fit into a template\, res
ulting in letters of varying quality\, and apparently much amusement for S
trachey. The poetry competition required the entrants\, mostly PhD student
s\, to write programs whose output or source code was in some way poetic:
the entries displayed remarkable ingenuity. Various analyses of Strachey
’s work depict it as a parody of attitudes to love\, an artistic endeavo
ur\, or as a technical exploration. In this talk I will consider how these
apply to the Newcastle competition and add my own interpretations.\nSpeak

DESCRIPTION:In the aftermath of the Thirty Years War (1618–1648)\, the m
ining regions of Central Europe underwent numerous technical and political
evolutions. In this context\, the role of underground geometry expanded c
onsiderably: drawing mining maps and working on them became widespread in
the second half of the seventeenth century. The new mathematics of subterr
anean surveyors finally realized the old dream of “seeing through stones
\,” gradually replacing alternative tools such as written reports of vis
itations\, wood models\, or commented sketches.\n\nI argue that the develo
pment of new cartographic tools to visualize the underground was deeply li
nked to broad changes in the political structure of mining regions. In Sax
ony\, arguably the leading mining region\, captain-general Abraham von Sch
önberg (1640–1711) put his weight and reputation behind the new geometr
ical technology\, hoping that its acceptance would in turn help him advanc
e his reform agenda. At-scale representations were instrumental in justify
ing new investments\, while offering technical road maps to implement them

DESCRIPTION:\nStatus: This talk has been cancelled\nIn the hieratic Egypti
an mathematical texts\, which are extant from the periods of the Middle Ki
ngdom and the Second Intermediate Period\, the verb form sDm.xr.f has its
most numerous attestations. This verb form has been recognized to express
a necessary consequence from a previously stated situation\, e.g. in indic
ating the result of a previously stated arithmetic operation. Therefore on
e might expect this form to be similarly (frequently) used in Egyptian law
s to express the consequences of wrongdoing. Only few collections of laws
from pharaonic times are extant\, of which the earliest are the Great Edic
t of Haremhab and the Nauri Decree of Sethos I. both from the beginning of
the Ramesside Period. These sources\, however\, show no use of this form.
In this respect then\, the Egyptian concept of rational practice is diffe
rent from its Mesopotamian neighbour\, where a connection between mathemat
ical and legal procedure texts has been shown by Jim Ritter based on their
verbal structure. Using examples from several Egyptian genres of texts\,
I would like to document that in ancient Egypt\, too\, this relation exist
ed\, and explore how it was expressed.\nSpeakers:\nAnnette Imhausen (Goeth

DESCRIPTION:American mathematics was experiencing growing pains in the 192
0s. It had looked to Europe at least since the 1890s when many Americans h
ad gone abroad to pursue their advanced mathematical studies. It was anxi
ous to assert itself on the international—that is\, at least at this mom
ent in time\, European—mathematical scene. How\, though\, could the Amer
icans change the European perception from one of apprentice/master to one
of mathematical equals? How could Europe\, especially Germany but to a les
ser extent France\, Italy\, England\, and elsewhere\, come fully to sense
the development of the mathematical United States? If such changes could
be effected at all\, they would likely involve American and European mathe
maticians in active dialogue\, working shoulder to shoulder in Europe and
in the United States\, and publishing side by side in journals on both sid
es of the Atlantic. This talk will explore one side of this “equation”
: European mathematicians and their experiences in the United States in th
e 1920s.\nSpeakers:\nKaren Hunger Parshall (University of Virginia)

Hartree and Porter's original model\, which is also made from Meccano.\n\n
The 'Kent Machine' sits at a unique intersection of historical research an
d educational engagement\, providing an alternative way of teaching STEM s

Wheel' apparatus\, inviting attendees to physically re-enact the mathemat

DESCRIPTION:Charles Babbage (1791–1871) was Lucasian Professor of mathem
atics in Cambridge from 1828–1839. He displayed a fertile curiosity that
led him to study many contemporary processes and problems in a way which
emphasised an analytic\, data driven view of life.\n\nIn popular culture B
abbage has been celebrated as an anachronistic Victorian engineer. In real
ity\, Babbage is best understood as a figure rooted in the enlightenment\,
who had substantially completed his core investigations into 'mechanisati
on of thought' by the mid 1830s: he is thus an anachronistic Georgian: the
construction of his first difference engine design is contemporary with t
he earliest public railways in Britain.\n\nA fundamental question that mus
t strike anybody who examines Babbage's precocious designs is: how could o
ne individual working alone have synthesised a workable computer design\,
designing an object whose complexity of behaviour so far exceeded that of
contemporary machines that it would not be matched for over a hundred year
s?\n\nWe shall explore the extent to which the answer lies in the techniqu
es Babbage developed to reason about complex systems. His Notation which s
hows the geometry\, timing\, causal chains and the abstract components of
his machines\, has a direct parallel in the Hardware Description Languages
developed since 1975 to aid the design of large scale electronics. In thi
s presentation\, we shall provide a basic tutorial on Babbage's notation s
howing how his concepts of 'pieces' and 'working points' effectively build
a graph in which both parts and their interactions are represented by nod
es\, with edges between part-nodes and interaction-nodes denoting ownershi
p\, and edges between interaction-nodes denoting the transmission of force
s between individual assemblies within a machine. We shall give examples f
rom Babbage's Difference Engine 2 for which a complete set of notations wa
s drawn in 1849\, and compare them to a design of similar complexity speci
fied in 1987 using the Inmos HDL.\nSpeakers:\nAdrian Johnstone (Royal Holl

DESCRIPTION:It is unnecessary to emphasize important place of algorithms i
n computer science. Many efficient and convenient algorithms are designed
by borrowing or revising ancient mathematical algorithms and methods. For
example\, recursive method\, exhaustive search method\, greedy method\,
“divide and conquer” method\, dynamic programming method\, reiteration
algorithm\, circulation algorithm\, among others. \n\nFrom the perspecti
ve of the history of computer science\, it is necessary to study the histo
ry of algorithms used in the computer computations. The history of algorit
hms for computer science is naturally regarded as a sub-object of history
of mathematics. But historians of mathematics\, at least those who study h
istory of mathematics in China\, have not realized it is important in the
history of mathematics. Historians of Chinese mathematics paid little atte
ntion to these studies\, mainly having not considered from this research a
ngle. Relevant research is therefore insufficient in the field of history
of mathematics. \n\nThe mechanization thought and algorithmization charact
eristic of Chinese traditional (and therefore\, East Asian) mathematics\,
however\, are coincident with that of computer science. Traditional Chines
e algorithms\, therefore\, show their importance historical significance i
n computer science. It is necessary and important to survey traditional al
gorithms again from the point of views of computer science. It is also ano
ther angle for understanding traditional Chinese mathematics. \n\nThere ar
e many things in the field that need to be researched. For example\, when
and how were these algorithms designed? What was their mathematical backgr
ound? How were they applied in ancient mathematical context? How are their
complexity and efficiency of ancient algorithms? \n\nIn the present paper
\, we will study the circulation structure in traditional Chinese mathemat
ical algorithms. Circulation structures have great importance in the compu
ter science. Most algorithms are designed by means of one or more circulat
ion structures. Ancient Chinese mathematicians were familiar them with the
circulation structures and good at their applications. They designed a lo
t of circulation structures to obtain their desirable results in mathemati
cal computations. Their circulation structures of dozen ancient algorithms
will be analyzed. They are selected from mathematical and astronomical tr
eatises\, and also one from the Yijing (Book of Changes)\, the oldest of t
he Chinese classics. \nSpeakers:\nGUO Shirong (Institute for the History o

DESCRIPTION:Jacob Bernoulli is known for his studies of the curves\, infin
itesimal math- ematics and statistics. However\, before being a professor
in mathematics\, he taught experimental physics at the University of Basel
. This explains his high interest in solving physical problems with newly
developed Leibnizian calculus. In his scientific notebook\, Meditationes\,
there are more than thirty notes about various mechanical problems for so
lving of which Bernoulli has applied Leibnizian calculus and has advanced
this method along the way. A discussion with a craftsman brought Bernoulli
’s attention to the problem of the strength of a beam early in his caree
r and occupied his mind until his death. The craftsman’s narration based
on his experience highlighted the flaws in Galilean-Leibnizian theory of
the strength of a beam. This was the starting point of Bernoulli’s quest
to mathematically find the profile of a bent beam (the Elastica Problem)
and the physical laws governing it. He started a challenge to encourage ot
her mathematicians of the time to study the problem\, providing a hint hid
den in an anagram. Although he published his solution of the Elastica Prob
lem in 1694\, that was not the end of the quest for him. Studying his unpu
blished notes in Meditationes reveals that over the last decade of his lif
e\, Bernoulli has reconsidered the problem. In my project\, I demonstrate
that he has found remarkable concepts such as mean tensile stress\, and th
e notion of local stress-strain relation\, etc.\nSpeakers:\nSepideh Alassi

DESCRIPTION:The Oberwolfach Research Institute for Mathematics (Mathematis
ches Forschungsinstitut Oberwolfach/MFO) was founded in late 1944 by the F
reiburg mathematician Wilhelm Süss (1895-1958) as the „National Institu
te for Mathematics“. In the 1950s and 1960s the MFO developed into an in
creasingly international conference centre.\n\nThe aim of my project is to
analyse the history of the MFO as it institutionally changed from the Nat
ional Institute for Mathematics with a wide\, but standard range of respon
sibilities\, to an international social infrastructure for research comple
tely new in the framework of German academia. The project focusses on the
evolvement of the institutional identity of the MFO between 1944 and the e
arly 1960s\, namely the development and importance of the MFO’s scientif
ic programme (workshops\, team work\, Bourbaki) and the instruments of res
earch employed (library\, workshops) as well as the corresponding strategi
es to safeguard the MFO’s existence (for instance under the wings of the
Max-Planck-Society). In particular\, three aspects are key to the project
\, namely the analyses of the historical processes of (1) the development
and shaping of the MFO’s workshop activities\, (2) the (complex) institu
tional safeguarding of the MFO\, and (3) the role the MFO played for the r
e-internationalisation of mathematics in Germany. Thus the project opens a
window on topics of more general relevance in the history of science such
as the complexity of science funding and the re-internationalisation of t
he sciences in the early years of the Federal Republic of Germany.\nSpeake

made the calculation of solar eclipse much more complex than before. The s
trategy that Chinese calendar-makers dealt with was different from the geo
metrical model system like Greek astronomers taken as. What Chinese astron

DESCRIPTION:The emergence of analytic methods in the 17th century opened a
new way in order to tackle the elucidation of certain quantities. The str
ong presence of the circle-squaring problem\, focused mainly the attention
on π\, on which besides the serious doubts about its rationality\, it ar
ises an awareness---boosted by the new algebraic approach---of the difficu
lty of framing it inside algebraic boundaries. The term ``transcendence''
emerges in this context but with a very ambiguous meaning.\n\nThe first gr
eat step towards its comprehension\, took place in the 18th century and ca
me from Johann Heinrich Lambert's hand\, who using a new analytical machin
ery---continued fractions---gave the first proof of irrationality of π. T
he problem of keeping this number inside the algebraic limits\, also recei
ves an especial attention at the end of his 'Mémoires sur quelques propri
étés remarquables des quantités transcendantes\, circulaires et logarit
hmiques'\, published by the Berlin Academy of Science in 1768. In this wor
k\, Lambert after giving to the term ``transcendence'' its modern meaning\
, conjectures the transcendence of π and therefore the impossibility of s
quaring the circle.\nSpeakers:\nEduardo Dorrego López (Seville)

DESCRIPTION:The Czech lands were the most industrial part of the Austrian-
Hungarian monarchy\, broken up at the end of the WW1. As such\, Czechoslov
akia inherited developed industry supported by developed system of tertiar
y education\, and Czech and German universities and technical universities
\, where the first chairs for applied mathematics were set up. The close c
ooperation with the Skoda company led to the establishment of joint resear
ch institutes in applied mathematics and spectroscopy in 1929 (1934 resp.)
.\n\nThe development of industry was followed by a gradual introduction of
social insurance\, which should have helped to settle social contracts\,
fight with pauperism and prevent strikes. Social insurance institutions se
t up mathematical departments responsible for mathematical and statistical
modelling of the financial system in order to ensure its sustainability.
During the 1920s and 1930s Czechoslovakia brought its system of social ins
urance up to date. This is connected with Emil Schoenbaum\, internationall
y renowned expert on insurance (actuarial) mathematics\, Professor of the
Charles University and one of the directors of the General Institute of Pe
nsions in Prague.\n\nAfter the Nazi occupation in 1939\, Czech industry wa
s transformed to serve armament of the Wehrmacht and the social system hel
ped the Nazis to introduce the carrot and stick policy to keep weapons pro
duction running up to early 1945. There was also strong personal discontin
uity\, as the Jews and political opponents either fled to exile or were br
utally persecuted.\nSpeakers:\nJan Kotůlek (Technical University of Ostra
