In 1956, the Dutch graphic artist M.C. Escher made an unusual lithograph with the title `Print Gallery‘. It shows a young man viewing a print in an exhibition gallery. Amongst the buildings depicted on the print, he sees paradoxically the very same gallery that he is standing in. A lot is known about the way in which Escher made his lithograph. It is not nearly as well known that it contains a hidden `Droste effect‘, or infinite repetition; but this is brought to light by a mathematical analysis of the studies used by Escher. On the basis of this discovery, a team of mathematicians at Leiden produced a series of hallucinating computer animations. These show, among others, what happens inside the mysterious spot in the middle of the lithograph that Escher left blank.

"Cannons at Sparrows". Hirzebruch lecture by Günter M. Ziegler on Wednesday, November 2

The story told in this lecture starts with an innocuous little geometry problem, posed in a September 2006 blog entry by R. Nandakumar, an engineer from Calcutta, India: "Can you cut every polygon into a prescribed number of convex pieces that have equal area and equal perimeter?" This little problem is a "sparrow", tantalizing, not as easy as one could perhaps expect, and Recreational Mathematics: of no practical use.

Hausdorff Cinema at MPIM: The Discrete Charm of Geometry

MPIM Lecture Hall

A team of mathematicians is working together on a big project. Excitement of discovery, hope and disappointment, competition and recognition are shown from an infinitely close distance. Scientists united by the idea of discretization, which, in short, means: constructing continuous objects from basic building blocks. Akin to the scientists’ search for the right discretization of continuum, this film itself is composed of fragments – individual characters of different ages, temperaments and scientific approaches – which form a single continuous melody.

MPIM Lecture Hall

This Thursday, January 21st at 19:00h, members of the larger MPIM community will give us the honor of an informal musical concert. First, Carmen Rovi (Piano), Matthias Kreck (Cello), and Yael Fregier (Baritone) will play and sing classical pieces by Mozart, Schubert, Schumann, and Wagner. This is followed by a short break and some traditional folk music performed by the MPIM folk group with Tim Ballance (fiddle)Kristian Hodén (button accordeon), Pavel Mnev (flutes), Davide Spriano (electric bass), and Alessandro Valentino (acoustic guitar). Everybody from the math community in Bonn and their families are welcome.

A Voyage of the Intellects: A Global History of Mathematics in the 17th century

Location: 
MPIM Lecture Hall
What is the history of mathematics? And who is it written for? This talk introduces the world history of mathematics in the 17th century to a general audience; unlike the conventional approach of viewing the history of mathematics in order to make a comparison between different parts of the world, this talk traces the pathway of mathematical ideas across nations, and observes the 17th century world on a global scale. We will start our journey in Kyoto, and will investigate the intellectual cultures of Europe and China. The presentation uses various techniques of digital humanities.

Geometry, Analysis, and Gravitation. Hirzebruch Lecture 2014 by Gerhard Huisken

Since ancient times geometric concepts have been used to model astronomical phenomena such as the motion of the planets. In modern times geometry has merged with analysis to provide accurate models of gravitational phenomena involving stars and their planets, black holes and gravitational waves in the context of General Relativity - with the new mathematical insights leading also to progress in the understanding of many other phenomena surrounding us. The lecture describes in a non-technical way how ancient geometric concepts such as the isoperimetric inequality as well as classical concepts from Newtonian physics reappear in the curved space-times of General Relativity.

Do musical improvisation and mathematics research have anything in common? A public jazz performance and mathematics discussion with Rob Schneiderman

MPIM Lecture Hall

"Mathematics is not only a solo gig. When two or three mathematicians get together to share their ideas on how to attack a problem, sessions can easily stretch out for hours and even days. The dynamic is not unlike jazz musicians improvising with each spurring the other to go farther than they would go alone." Rob Schneiderman, New York based mathematician, regular guest at the Max Planck Institute for Mathematics, and professional Jazz pianist together with John Goldsby (bass) and Hans Dekker (drums) will explore the relations between Jazz & Math in a public concert with open discussion. (Free admission)

„The extra-scientific in scientific creativity: Galileo's mechanics and Bohr's quantum atom“. Hirzebruch lecture by John Heilbron

John L. Heilbron is Professor of History and Vice-Chancellor Emeritus, University of California, Berkeley, and Honorary Fellow, Worcester College, Oxford. His talk is drawn from material in and reflections on his recent books, Galileo (2010) and (with Finn Aaserud) Love, literature, and the quantum atom. Niels Bohr's 1913 trilogy revisited (2013), both from Oxford University Press.

This documentary is a celebration of the story of Ramanujan while walking in his footsteps trying to fathom his genius. I will begin with a very short (less than 5 minutes) introduction to the making of the documentary. Then we will watch the documentary; it is about one hour long. Finally, I can (try to) answer any questions the audience might have.

The Secret Mathematicians. Hirzebruch lecture by Marcus du Sautoy

From composers to painters, writers to choreographers, the mathematician’s palette of shapes, patterns and numbers has proved a powerful inspiration. Often subconsciously artists are drawn to the same structures that fascinate mathematicians as they constantly hunt for interesting new structures to frame their creative process. Through the work of artists like Borges and Dali, Messiaen and Laban, Professor du Sautoy will explore the hidden mathematical ideas that underpin their creative output and reveal that the work of the mathematician is also driven by strong aesthetic values.

Location: 
MPIM Lecture Hall

Anges Handwerk and Harrie Willems have made a remarkable documentary about the life and work of Yuri Manin, Emeritus Director at the Max Institute for Mathematics in Bonn, who began his career as a student at Moscow State University in the year of Stalin's death 1953 and whose subsequent professional life reflects the history of mathematics and mathematicians trying to overcome the political constraints of that time. The film will be shown for the first time in Bonn, prior to its publication by Springer in 2012. The directors will be present and available for questions and discussion after the screening.

 »Ein Mathematiker, der nicht etwas Poet ist, wird nimmer ein vollkommener Mathematiker sein«, schreibt der Mathematiker Weierstraß im August 1883 an Sofja Kowalewskaja. Aber ist die Mathematik als exakteste der Wissenschaften nicht eigentlich die Gegenspielerin der Poesie? Ist es nicht wie für Lessing »gewiß, daß dasjenige, was die Poesie von der Mathematik borgt, den Witz vertrocknet und ihn zu einer körperlichen Genauigkeit gewöhnet, welche mit der metaphysischen Genauigkeit der Dichter gar keine Verwandtschaft hat«?

Ein kurzes Gegenbeispiel, das der junge Theodor Vahlen 1891 veröffentlichte und das ein halbes Jahrundert lang als Teil des mathematisches Menscheitswissens galt, wurde plötzlich im Zweiten Weltkrieg druch Oskar Perron zum Mittelpunkt einer politisch-mathematischen Debatte. Im ersten Teil des Vortrags erinnern wir zunächst an diese Geschichte. Das Beispiel ist schon deshalb interessant, weil mathematisch-politische Debatten nicht sehr häufig sind. Ausserdem aber werfen wir im zweiten Teil einen frischen Blick auf das Problem.
